Climate Change

The world is warming up, with 2023 being by far the hottest year since record keeping began and 2024 shaping up to be hotter yet. But these changes only involve one or two degrees. What's the big deal?

The amount of energy required to raise the temperature of one liter of water by one degree is one kilocalorie (kcal). Scaling up, the amount of energy required for a one-degree increase in the water temperature of the Gulf of Mexico is 2,434,000,000,000,000,000 kcals. That's 25 million times more energy than released by the WW-II atomic bomb that destroyed the city of Hiroshima and killed more than 100,000 people.

So, for every one degree increase in water temperature, the Gulf of Mexico takes on 25-million atomic bombs worth of new energy, which is then available to fuel hurricanes and other storms. Maybe a one-degree rise in temperature is a big deal.

Medications, epilepsy and climate change: Added layers of complexity.

British journal of clinical pharmacology [Epub ahead of print].

Climate change-the global crisis with pervasive health impacts-has adverse consequences for people with epilepsy (PWE) who have low quality of life due to poor seizure control, socioeconomic disadvantages and comorbidities. This review focuses on the potential effects of climate change on the pharmacological characteristics of antiseizure medications (ASMs), antipsychotics and antidepressants. We note that findings particularly obtained from physicochemical stability studies have been demonstrated experimentally for some specific environmental conditions whereas studies for clinical outcome effects are very limited. Carbamazepine, valproate, phenytoin or lorazepam appear to be ASMs at risk of being affected by high temperature and/or humidity. Even the stability of blood samples needs to be considered during transportation to therapeutic drug monitoring units, particularly for the PWE living in low-income countries that are facing the most challenges of climate change effects attributed to low infrastructure and healthcare system capacity. We need more urgent research investigating drug responses of PWE regarding especially the effects of adverse weather events such as heatwaves on physicochemical stability or pharmacokinetics of drugs in a complex interaction with the vulnerabilities of individuals, accompanying neuropsychiatric disorders and geographical challenges. Then we will be able to develop pharmacological treatment strategies to improve the quality of life of PWE during adverse weather events.

Impacts of Climate Change on the Spatial Distribution and Habitat Suitability of Nitraria tangutorum.

Plants (Basel, Switzerland), 14(10):.

Nitraria tangutorum (Zygophyllaceae) is an ecologically and economically valuable shrub, locally dominant in the arid and semi-arid deserts of northwest China owing to its exceptional drought resistance and salt tolerance. In this study, environmental variable importance was evaluated within the MaxEnt model using percent-contribution metrics, based on 154 distribution records of N. tangutorum and 14 bioclimatic and soil-related environmental variables. We identified the five key variables of N. tangutorum distribution as follows: Precipitation of the Wettest Quarter (Bio16), Topsoil Sodicity (T_esp), Topsoil Electroconductibility (T_ece), Topsoil Car-bonate or lime content (T_CACO3), and Precipitation of the Driest Month (Bio14). The constructed MaxEnt model was then used to project the potential distribution areas of N. tangutorum under the four Shared Socioeconomic Pathways (SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5) for both current climate conditions and future climate conditions (2050s and 2090s). The results indicate that, under present-day conditions, high-suitability areas occur primarily in Xinjiang, Gansu, Qinghai, Inner Mongolia, and Ningxia; in future climate scenarios, the suitable habitat for N. tangutorum is anticipated to shrink by the 2050s but is expected to gradually recover by the 2090s. As time progresses, the suitable habitat areas will generally expand towards higher latitude regions. These findings demonstrate N. tangutorum's strong adaptive potential to climate change and provide a scientific basis for its targeted introduction, cultivation, and long-term management in desert restoration and ecological rehabilitation projects.

The Role of Insect-Based Feed in Mitigating Climate Change: Sustainable Solutions for Ruminant Farming.

Insects, 16(5):.

There has been an unprecedented demand for livestock production due to factors such as the ever-increasing population, limited resources (land, water, feed, etc.), and changing human lifestyles. Moreover, due to the interconnected nature of the world's biodiversity crisis, pollution, and climate change, environmental sustainability is going to play a pivotal role in addressing these pressing issues. Because of their high nutritional value and environmental benefits compared to conventional livestock feeds, insects as animal feed have demonstrated great potential for long-term sustainability. The current state of the IBF application on ruminants is presented in this review, together with its challenges, future direction, and strength-weakness-opportunity-threat analysis. The results from many studies on ruminants have demonstrated that insect nutrients-primarily amino acids, protein, and fat-are highly digestible, safe, and beneficial to ruminant health and productivity. Additionally, they do not harm the ruminant fermentation and microbiota, even having the benefit of possibly lowering ruminant farms' well-known methane emissions. Nevertheless, concerns continue to arise because this method is still relatively new and there is a lot of unexplored knowledge; as a result, regulation is not yet well established globally, which is a barrier to its implementation.

Climate Change: A Major Factor in the Spread of Aedes aegypti (Diptera: Culicidae) and Its Associated Dengue Virus.

Insects, 16(5):.

Climate change is thought to be responsible for the spread of various vector-borne diseases. The current study was conducted to evaluate the impact of different temperature and relative humidity regimes on the developmental stages of the yellow fever mosquito, Aedes aegypti (Diptera: Culicidae). The study also evaluated the impact of larval density on the survival of Ae. aegypti. In addition, the association between vector larval abundance, dengue incidence, and climatic factors were elucidated during 2016-2019 in three populated districts of Punjab, Pakistan, i.e., Lahore, Rawalpindi, and Multan. The results of the study revealed that at 10 °C and 35 °C, egg hatching and adult emergence were significantly reduced, regardless of the relative humidity. In contrast, at 20 °C and 30 °C, the rates of egg and adult survival increased with higher relative humidity. In addition, a density-dependent response was observed regarding larval survival of Ae. aegypti. Moreover, larval incidence was positively correlated with the number of dengue patients, Tmax, RH, and precipitation at Lahore (0.55, 0.23, 0.29, and 0.13), Rawalpindi (0.90, 0.30, 0.21, and 0.14), and Multan (0.05, 0.27, and 0.13) respectively, except in Multan, where a negative correlation (-0.09) with precipitation was observed. The inflow of patients had a positive correlation with the occurrence of a larval population, relative humidity, and precipitation at Lahore, Rawalpindi, and Multan districts, with the scale values of 0.55, 0.25, and 0.16; 0.90, 0.22, and 0.03; and 0.05, 0.06, and 0.03, respectively. In addition, a forecast model, ARIMA, predicted that there was a higher rate of larval occurrence in Rawalpindi, followed by Lahore. This study concluded that the role of precipitation > 200 mm prior to a 1-2-month lag, a 20-30 °C temperature range, and an RH exceeding 60% lead to the occurrence of larvae and dengue case spikes. This study will help to reinforce dengue surveillance and control strategies in Pakistan and to establish early management strategies based on changing climatic factors.

Current and Future Spatial Distribution of the Aedes aegypti in Peru Based on Topoclimatic Analysis and Climate Change Scenarios.

Insects, 16(5):.

Dengue, a febrile disease that has caused epidemics and deaths in South America, especially Peru, is vectored by the Aedes aegypti mosquito. Despite the seriousness of dengue fever, and the expanding range of Ae. aegypti, future distributions of the vector and disease in the context of climate change have not yet been clearly determined. Expanding on previous findings, our study employed bioclimatic and topographic variables to model both the present and future distribution of the Ae. aegypti mosquito using the Maximum Entropy algorithm (MaxEnt). The results indicate that 10.23% (132,053.96 km[2]) and 23.65% (305,253.82 km[2]) of Peru's surface area possess regions with high and moderate distribution probabilities, respectively, predominantly located in the departments of San Martín, Piura, Loreto, Lambayeque, Cajamarca, Amazonas, and Cusco. Moreover, based on projected future climate scenarios, it is anticipated that areas with a high probability of Ae. aegypti distribution will undergo expansion; specifically, the extent of these areas is estimated to increase by 4.47% and 2.99% by the years 2070 and 2100, respectively, under SSP2-4.5 in the HadGEM-GC31-LL model. Given the increasing dengue epidemic in Peru in recent years, our study seeks to identify tools for effectively addressing this pressing public health concern. Consequently, this research serves as a foundational framework for assessing areas with the highest likelihood of Ae. aegypti distribution in response to projected climate change in the second half of the 21st century.

Potential Distribution of Anoplophora horsfieldii Hope in China Based on MaxEnt and Its Response to Climate Change.

Insects, 16(5):.

Anoplophora horsfieldii Hope, a potential pest of the Cerambycidae family, is widely distributed throughout China, where it can cause damage to various living tree species. It has emerged as a critical invasive organism threatening China's agricultural and forestry production as well as ecological security. This study comprehensively analyzed the key environmental factors influencing the geographical distribution of A. horsfieldii and its spatiotemporal dynamics by integrating multi-source environmental data and employing ecological niche modeling. Model validation demonstrated high reliability and accuracy of our predictions, with an area under the receiver operating characteristic curve (AUC) value of 0.933, Kappa coefficient of 0.704, and true skill statistic (TSS) reaching 0.960. Our analysis identified four dominant environmental factors governing the distribution of A. horsfieldii: mean diurnal range (Bio2), temperature annual range (Bio7), precipitation of driest quarter (Bio17), and precipitation of coldest quarter (Bio19). Under current climatic conditions, the total potential suitable distribution area for A. horsfieldii was estimated at 212.394 × 10[4] km[2], primarily located in central, southern, eastern, southwestern, and northwestern China. Future projections under three climate scenarios (SSP1-2.6, SSP2-4.5, and SSP5-8.5) suggest significant reductions in highly and moderately suitable habitats, while low-suitability areas may expand into central, eastern, and southwestern regions, with Chongqing, Henan, and Anhui potentially becoming new suitable habitats. Concurrently, the centroid coordinates of suitable habitats exhibited a directional shift toward Guangdong Province, with the overall distribution pattern demonstrating a spatial transition characterized by movement from inland to coastal areas and from higher to lower latitudes. This study provides scientific theoretical support for forestry authorities in controlling the spread of A. horsfieldii, while establishing a solid foundation for future ecological conservation and biosecurity strategies. The findings offer both theoretical insights and practical guidance for pest management and ecosystem protection.

Impact of Climate Change on Schistosomiasis Transmission and Distribution-Scoping Review.

International journal of environmental research and public health, 22(5): pii:ijerph22050812.

Schistosomiasis, a neglected tropical disease caused by parasitic worms of the genus Schistosoma and transmitted through freshwater snails, affects over 200 million people worldwide. Climate change, through rising temperatures, altered rainfall patterns, and extreme weather events, is influencing the distribution and transmission dynamics of schistosomiasis. This scoping review examines the impact of climate change on schistosomiasis transmission and its implications for disease control. This review aims to synthesize current knowledge on the influence of climate variables (temperature, rainfall, water bodies) on snail populations, transmission dynamics, and the shifting geographic range of schistosomiasis. It also explores the potential effects of climate adaptation policies on disease control. The review follows the Arksey and O'Malley framework and PRISMA-ScR guidelines, including studies published from 2000 to 2024. Eligible studies were selected based on empirical data on climate change, schistosomiasis transmission, and snail dynamics. A two-stage study selection process was followed: title/abstract screening and full-text review. Data were extracted on environmental factors, snail population dynamics, transmission patterns, and climate adaptation strategies. Climate change is expected to increase schistosomiasis transmission in endemic regions like Sub-Saharan Africa, Southeast Asia, and South America, while some areas, such as parts of West Africa, may see reduced risk. Emerging hotspots were identified in regions not currently endemic. Climate adaptation policies, such as improved water management and early warning systems, were found effective in reducing transmission. Integrating climate adaptation strategies into schistosomiasis control programs is critical to mitigating the disease's spread, particularly in emerging hotspots and shifting endemic areas.

Exploring Policies, Strategies, and Legislations Related to the One Health Approach to Zoonoses, Antimicrobial Stewardship, and Climate Change in Jordan: A Multimethod Study with SWOT Analysis.

International journal of environmental research and public health, 22(5): pii:ijerph22050749.

Background: Mapping policies, strategies, and legislations related to disease prevention in Jordan is pivotal for strengthening the country's public health infrastructure. The aims of our study were to identify, review, and map the existing national policies, strategies, and legislations related to the One Health approach to zoonoses, antimicrobial stewardship (AMS), and climate change in Jordan. Additionally, we identified the key strengths and major gaps and uncovered opportunities for enhancement. The current paper reports a part of a nationwide project which was jointly executed in 2023 by the Jordan Center for Disease Control and the Health Care Accreditation Council. Methods: A multimethod approach was employed, including a comprehensive desk review of any existing policies, strategies, and legislations, along with key informant interviews involving key stakeholders. The combination of the desk review and key informant interviews allowed for a more nuanced understanding of the gaps, strengths, and challenges in Jordan's approach to One Health, AMS, and climate change adaptation. By triangulating the findings from both methods, the study was able to cross-validate its results and ensure greater reliability and accuracy in its conclusions. Results: Our analyses revealed that Jordan has made notable progress in integrating the One Health approach within its regulatory framework, particularly in managing zoonotic diseases, AMS, and climate change. Nevertheless, there is a need for more explicit and effective intersectoral coordination. While the country's AMS initiatives are supported by a national action plan, they are limited by inadequate public awareness, veterinary regulations, and monitoring systems. Moreover, Jordan's climate change strategies, aligned with broader sustainability goals and integrated into national frameworks like the environmental protection law, are constrained by a lack of emergency preparedness and multisectoral collaboration. The SWOT analysis highlighted strengths, including robust legal structures and international collaborations, while identifying gaps in enforcement and the need for updated guidelines. Opportunities exist to enhance the reporting mechanisms, public awareness, and international partnerships. Conclusions: Jordan's integration of the One Health approach to zoonotic diseases, AMS, and climate change adaptation into its disease prevention policies is commendable and aligns with global health priorities. To further enhance these initiatives, Jordan could benefit from updating its public health law and the relevant guidelines and policies, strengthening and structuring public awareness campaigns, and developing detailed climate change adaptation strategies.

Changes in the Distribution Range of the Genus Cardiocrinum in China Under Climate Change and Human Activities.

Biology, 14(5): pii:biology14050581.

Cardiocrinum are perennial herbaceous plants of the Liliaceae family with high ornamental, nutritional, and medicinal value. However, critical knowledge gaps remain regarding the following: (1) the fine-scale habitat preferences of Cardiocrinum; (2) the key ecological drivers influencing their growth and distribution. The MaxEnt software 3.4.1 was used to simulate the current and future suitable habitats of Cardiocrinum, evaluate the impacts of environmental changes on its distribution, and determine the distribution changes under climate change scenarios. The AUC value of the model used in the current study was >0.98, which indicates that the model had good accuracy. The results show that as a typical understory herb, precipitation in the warmest quarter (bio18) and temperature seasonality (bio04) are the main factors affecting the distribution of Cardiocrinum. In addition, Cardiocrinum giganteum and Cardiocrinum giganteum var. yunnanense are also affected by slope and human activity. Under the SSP126, SSP245, and SSP585 climate scenarios, the suitable habitat areas of Cardiocrinum cathayanum and C. giganteum showed an increasing trend. The suitable habitat area of C. giganteum var. yunnanense increased under the SSP126 climate scenario; however, it substantially declined in SSP245 and SSP585 scenarios. The distribution area of Cardiocrinum shifted to higher latitudes. The centroid of C. cathayanum shifted more than 5 degrees of latitude during SSP585 2081s, while the centroid of C. giganteum and C. giganteum var. yunnanense did not shift more than 2 degrees of latitude. In addition, the centroid longitudes of C. giganteum and C. giganteum var. yunnanense shifted westward under the three climate scenarios. There is ecological niche differentiation among C. cathayanum and others, whilst C. giganteum and C. giganteum var. yunnanense have overlapping ecological niches. In the future, we will strengthen the protection of wild Cardiocrinum resources in accordance with environmental factors and suitable habitats for Cardiocrinum.

MaxEnt Modeling of the Impacts of Human Activities and Climate Change on the Potential Distribution of Plantago in China.

Biology, 14(5): pii:biology14050564.

Human activities exert both beneficial and detrimental impacts on the ecosystem. In recent years, greenhouse gas emissions have significantly increased due to global climate change, causing profound alterations in ecosystem distribution and productivity. The synergistic interplay between climatic shifts and anthropogenic activities is intensifying ecological transformations and disturbances, and accelerating biodiversity depletion. The Plantago genus (Plantaginaceae family) includes 14 herbaceous species among China's flora. This study was conducted to elucidate the spatial distribution of Plantago species patterns across China and evaluate their differential responses to impending climate change and human interventions. In this study, we projected the potential distributions of Plantago species under three climate scenarios (SSP126, SSP245, and SSP585) across current and future temporal intervals (2021-2040, 2041-2060, 2061-2080, and 2081-2100) using the MaxEnt model integrated with ArcGIS V10.8 spatial analysis. A spatial trend analyses was also conducted to assess habitat suitability dynamics by incorporating anthropogenic influence parameters. The model validation yielded AUC values exceeding 0.9, demonstrating excellent model performance and predictive reliability. Precipitation variability and anthropogenic pressure emerged as the most predominant determinants shaping Plantago distributions. Centroid migration analyses further indicated the progressive northward displacement of optimal habitats under the projected climate scenarios. These findings significantly advance our understanding of Plantago species' adaptive responses to environmental changes. This study also offers an invaluable scientific foundation for sustainable resource management and ecological conservation strategies.

Future Climate Change Increases the Risk of Suitable Habitats for the Invasive Macrophyte Elodea nuttallii.

Biology, 14(5): pii:biology14050504.

Elodea nuttallii is an ornamental macrophyte native to North America that has been introduced to Europe and Asia, and having been established, has had detrimental effects on local aquatic ecosystems. In this study, we developed an optimized MaxEnt model to predict the global potential habitat suitability for E. nuttallii under the influence of climate change. The model incorporated 20 relevant impact factors and occurrence record data for E. nuttallii. The results reveal that under current and future climate scenarios, potentially suitable habitats for E. nuttallii can be found on six assessed continents, mainly in Western Europe, western and eastern North America, southeastern Asia, southeastern Oceania, and scattered coastal areas in South America and Africa. Moreover, temperature and precipitation were identified as factors having significant effects on the distribution of E. nuttallii. In the future, the area of habitats potentially suitable for E. nuttallii is predicted to expand, particularly towards higher latitudes.

Qinghai Province (Tibetan Plateau): Quantifying the Influence of Climate Change and Human Activities on Vegetation Net Primary Productivity and Livestock Carrying Capacity Growth Potential.

Biology, 14(5): pii:biology14050494.

Quantitative exploration of shifts in regional vegetation net primary productivity (NPP) and their driving factors holds immense importance in unraveling the mechanisms steering vegetation alterations, comprehending the impact of climate variations and human interventions on NPP, and guiding ecological management. Despite this significance, there is a scarcity of research reports on Qinghai Province. The aim is to dissect the influences of climate change and human activities on Qinghai's vegetation NPP and to estimate the growth potential of livestock carrying capacity. This study addresses the gap by juxtaposing the characteristics of climate-induced potential NPP changes, computed using the Zhou Guangsheng model, with actual NPP changes, calculated via the CASA model. Our findings underscore climate factors as the predominant drivers of Qinghai's vegetation NPP, accounting for 64.6% of the total area. Regions influenced by human activities contribute 34.3%, while unchanged areas constitute 2%. Climate emerges as the primary catalyst for increased vegetation NPP in Qinghai, encompassing 87% of the total area, with 73% attributed to climate factors across all counties. Conversely, human activities predominantly lead to decreased NPP, affecting 11% of the total area. Notably, 99% of the reduced NPP is attributable to human activities, concentrated in Golmud, Mangya, and Dulan counties in the northwest. Examining the growth potential of livestock carrying capacity from 1982 to 2018 reveals a consistent upward trajectory in Qinghai Province. The average annual growth potential per unit area escalates from 0.38 SHU/ha in 1982 to 0.56 SHU/ha in 2018. By 2018, regions exhibiting positive growth potential encompass 95% of the province, with areas exceeding 1 SHU/ha constituting 9%, primarily situated in the eastern part of Qinghai Province.

Functional safeguards for conservation: Identifying climate change refugia for frugivorous and nectarivorous birds in a degraded area of Colombia.

PloS one, 20(5):e0321817 pii:PONE-D-24-31667.

Habitat loss and climate change are major drivers of biodiversity loss, but their synergistic effects and functional perspectives have to be better understood. We employed species distribution models under future contrasting socioeconomic scenarios to assess the impacts of climate change and human footprint on avian frugivore and nectarivore functional groups in the Magdalena Valley, a highly transformed and biodiverse region in Colombia. We constructed the functional groups based on a dissimilarity matrix with 16 anatomical and ecological traits. Two types of future climatic refugia (type 1: areas that will maintain the current climatic conditions and type 2: regions outside the current distribution area that will have the current climatic conditions) were identified to guide conservation efforts for these groups and associated ecosystem services. Of the 27 functional groups identified, 19 are projected to undergo range reductions of 1-75%, with an average upward shift of their climatic niches along the altitudinal gradient of 690 m. Large frugivores from intermediate elevations, such as toucans and cracids, as well as nectarivores with extreme adaptations and specializations, are expected to experience the most severe range reductions. Distributional and altitudinal shifts will lead to spatial reorganization of communities and a reduction or complete loss of functional group richness, particularly in lowland areas. This could impact ecosystem services relevant for degraded area restoration, such as seed dispersal, fruit availability, and pollination of specialized plant species with economic importance. The low representation of future climatic refugia within protected areas highlights the need to incorporate climate change trends into future conservation strategies for these landscapes.

Emerging Human Fascioliasis in India: Review of Case Reports, Climate Change Impact, and Geo-Historical Correlation Defining Areas and Seasons of High Infection Risk.

Tropical medicine and infectious disease, 10(5):.

The trematodes Fasciola hepatica and F. gigantica are transmitted by lymnaeid snails and cause fascioliasis in livestock and humans. Human infection is emerging in southern and southeastern Asia. In India, the number of case reports has increased since 1993. This multidisciplinary study analyzes the epidemiological scenario of human infection. The study reviews the total of 55 fascioliasis patients, their characteristics, and geographical distribution. Causes underlying this emergence are assessed by analyzing (i) the climate change suffered by India based on 40-year-data from meteorological stations, and (ii) the geographical fascioliasis hotspots according to archeological-historical records about thousands of years of pack animal movements. The review suggests frequent misdiagnosis of the wide lowland-distributed F. gigantica with F. hepatica and emphasizes the need to obtain anamnesic information about the locality of residence and the infection source. Prevalence appears to be higher in females and in the 30-40-year age group. The time elapsed between symptom onset and diagnosis varied from 10 days to 5 years (mean 9.2 months). Infection was diagnosed by egg finding (in 12 cases), adult finding (28), serology (3), and clinics and image techniques (12). Climate diagrams and the Wb-bs forecast index show higher temperatures favoring the warm condition-preferring main snail vector Radix luteola and a precipitation increase due to fewer rainy days but more days of extreme rainfall, leading to increasing surface water availability and favoring fascioliasis transmission. Climate trends indicate a risk of future increasing fascioliasis emergence, including a seasonal infection risk from June-July to October-November. Geographical zones of high human infection risk defined by archeological-historical analyses concern: (i) the Indo-Gangetic Plains and corridors used by the old Grand Trunk Road and Daksinapatha Road, (ii) northern mountainous areas by connections with the Silk Road and Tea-Horse Road, and (iii) the hinterlands of western and eastern seaport cities involved in the past Maritime Silk Road. Routes and nodes are illustrated, all transhumant-nomadic-pastoralist groups are detailed, and livestock prevalences per state are given. A baseline defining areas and seasons of high infection risk is established for the first time in India. This is henceforth expected to be helpful for physicians, prevention measures, control initiatives, and recommendations for health administration officers.

Extensive Variation in Thermal Responses and Toxin Content Among 40 Strains of the Cold-Water Diatom Pseudo-nitzschia seriata-In a Global Warming Context.

Toxins, 17(5):.

Phytoplankton are single-celled microorganisms with short generation times that may comprise high diversity in genetic and phenotypic traits, allowing them to acclimate to changes rapidly. High intraspecific genetic variation is well known in phytoplankton, but less is known about variation in physiological traits. To investigate variability and plasticity in genetic, morphological, and physiological traits of the toxigenic diatom genus Pseudo-nitzschia in a global warming scenario, we exposed 40 strains of the cold-water P. seriata to different temperatures (2 °C, 6 °C and 10 °C). The maximum growth rate and cellular toxin content showed extensive intraspecific variation, whereas morphological and genetic variation was minor. Thermal reaction norms showed a general increase in growth rate with increasing temperature; however, three distinct types of thermal responses were found among the 40 strains. All 40 strains contained toxins (domoic acid) in both exponential and stationary growth phase, and toxin content increased significantly with temperature. Most strains (>87%) contained measurable levels of domoic acid at all three temperatures. In conclusion, P. seriata shows extensive intraspecific variation in measured physiological traits like growth and toxin content, a variation exceeding the response of each strain to increases in temperature. Intraspecific variation in harmful species thus needs attention for the future understanding of food web dynamics, as well as the management and forecasting of harmful blooms.

Research on Digital Orthophoto Production Technology for Indoor Murals in the Context of Climate Change and Environmental Protection.

Journal of imaging, 11(5):.

In response to the urgent need for the sustainable conservation of cultural heritage against the backdrop of climate change and environmental degradation, this study proposes a low-cost, non-destructive digital recording method for murals based on close-range photogrammetry. By integrating non-metric digital cameras, total stations, and spatial coordinate transformation models, high-precision digital orthophoto generation for indoor murals was achieved. Experimental results show that the resolution error of this method is 0.02 mm, with root mean square errors (RMSE) of 3.51 mm and 2.77 mm in the X and Y directions, respectively, meeting the precision requirements for cultural heritage conservation. Compared to traditional laser scanning technology, the energy consumption of the equipment in this study is significantly reduced, and the use of chemical reagents is avoided, thereby minimizing the carbon footprint and environmental impact during the recording process. This provides a green technological solution to address climate change. Additionally, the low-cost nature of non-metric cameras offers a feasible option for cultural heritage conservation institutions with limited resources, promoting equity and accessibility in heritage protection amid global climate challenges. This technology provides sustainable data support for long-term monitoring, virtual restoration, and public digital display of murals while also offering rich data resources for virtual cultural tourism, public education, and scientific research. It demonstrates broad application potential in the context of climate change and environmental protection, contributing to the green transformation and sustainable development of cultural tourism.

Predicting Workplace Hazard, Stress and Burnout Among Public Health Inspectors: An AI-Driven Analysis in the Context of Climate Change.

European journal of investigation in health, psychology and education, 15(5):.

The increasing severity of climate-related workplace hazards challenges occupational health and safety, particularly for Public Health and Safety Inspectors. Exposure to extreme temperatures, air pollution, and high-risk environments heightens immediate physical threats and long-term burnout. This study employs Artificial Intelligence (AI)-driven predictive analytics and secondary data analysis to assess hazards and forecast burnout risks. Machine learning models, including eXtreme Gradient Boosting (XGBoost 3.0), Random Forest, Autoencoders, and Long Short-Term Memory (LSTMs), achieved 85-90% accuracy in hazard prediction, reducing workplace incidents by 35% over six months. Burnout risk analysis identified key predictors: physical hazard exposure (β = 0.76, p < 0.01), extended work hours (>10 h/day, +40% risk), and inadequate training (β = 0.68, p < 0.05). Adaptive workload scheduling and fatigue monitoring reduced burnout prevalence by 28%. Real-time environmental data improved hazard detection, while Natural Language Processing (NLP)-based text mining identified stress-related indicators in worker reports. The results demonstrate AI's effectiveness in workplace safety, predicting, classifying, and mitigating risks. Reinforcement learning-based adaptive monitoring optimizes workforce well-being. Expanding predictive-driven occupational health frameworks to broader industries could enhance safety protocols, ensuring proactive risk mitigation. Future applications include integrating biometric wearables and real-time physiological monitoring to improve predictive accuracy and strengthen occupational resilience.

Bumble Bee Probability of Occurrence Responds to Interactions Between Local and Landscape Land Use, Climatic Niche Properties and Climate Change.

Ecology letters, 28(5):e70145.

Insect biodiversity is changing rapidly, driven by a suite of pressures, notably land use, land-use intensification and increasingly climate change. We lack large-scale evidence on how land use and climate change interact to drive insect biodiversity changes. We assess bumble bee responses to interactive effects of land use and climate pressures across North America and Europe. The probability of occurrence increases in landscapes with a higher proportion of natural habitat and a shorter history of human disturbance. Responses to climate warming relative to historical conditions are weakly negative in natural habitats but positive in human land uses, while human land use reduces the probability of occurrence most in the centre of species' temperature niches. We estimate that the combined pressures have reduced bumble bee probability of occurrence by 44% across sampled natural habitats and 55% across human land uses, highlighting the pervasive influence that human pressures have had on biodiversity across habitats.

Achieving the Global Biodiversity Framework Under Climate Change.

Global change biology, 31(5):e70249.

We have committed to ambitious targets under the Global Biodiversity Framework, but projected climate change makes the achievement of many of these targets extremely difficult and will effectively require a significant rethinking in how to achieve multiple targets. In this Opinion, we have chosen to focus on selected targets, considering how their achievement is likely to be compromised by climate change but also what the possibility of real response options might be. We focus on restoration (Target 2), spatial planning and integration (Targets 1, 2, 3 and 10), sustainable use and sustainable benefits to people (Targets 5, 9 and 10) and, finally, equity and social justice (Targets 13, 20-23 and Goal C). Now more than ever, the window for effective action on climate change and biodiversity is closing, requiring rapid and, most importantly, collective action.

Climate Change and Mental Health: A Human Rights Perspective.

The Journal of law, medicine & ethics : a journal of the American Society of Law, Medicine & Ethics pii:S1073110525101149 [Epub ahead of print].

Climate change-related environmental harms have been observed to negatively affect mental health. While policymakers and courts around the world widely recognise the impacts of climate change on physical heath as potentially endangering human rights, the implications of climate change for mental health have received significantly less attention. This paper analyzed five cases that challenged national response to climate change and the resulting impacts on mental health before four different international human rights protection bodies. Four out of these five cases were dismissed either because the petitioners did not seek prior action before the national authorities, or because their claims were deemed unsubstantiated. Despite these outcomes, the protection bodies' treatment of these petitions as well as various other ongoing developments show that the human rights approach to climate change and mental health is gradually emerging at the international and domestic levels, but it is still in its early days and there are various challenges to it.

Projecting the effect of climate change on multiple Geomorphological hazard using machine learning data driven approaches.

Scientific reports, 15(1):18333.

Land subsidence (LS) and collapsed pipes (CP) pose environmental and socio-economic threats in arid and semi-arid regions. This study assesses the effect of climate change to address these problems in Khorasan-Razavi province, Iran. Thus, we mapped soil landforms susceptible to LS and CP based on climatic, geolocic, topoghraphic, hydrologic and edaphic variables using an ensemble forecasting approach. Additionally, we predicted the future susceptibility of CP and LS based on two future emission scenario pathways (SSP 5-8.5 and SSP 1-2.6), in 2030, 2050, 2070, and 2090. The assessment showed that the area under the ROC curve (AUC) indicated that the ensemble model accurately predicted the distribution of CP and LS (AUC > 0.8). Slope and clay content proved to be the most important factors affecting CP, whereas distance from faults and precipitation seasonality played more roles in LS susceptibility. The classification results indicated varying susceptibility levels to CP and LS in Khorasan-Razavi province, with approximately 31.58% categorized as low and 15.24% as very high LS susceptibility, while 42.71% were in the low CP susceptibility class. Overall, 57.16% of the area is safe from both hazards; however, 6.16% is vulnerable to both hazards, with more than 35% at risk for at least one hazard. Future prediction models suggest that up to approximately 4% of the area will consist susceptible to both hazards under both scenario emissions and less than 1% of the study area will reduce susceptibility for both studied hazards in future. The majority of regions that remain susceptible are in the southern province. These results guide for soil management to protect soil and water from the effects of humans and climate alternation in poor areas worldwide.

Wildlife Management and Climate Change: How to Adapt Harvest Rates of Wild Turkey According to Extreme Weather Events.

Environmental management [Epub ahead of print].

Climate change is forcing many species to shift their distribution north. Managing these expanding species is a challenge because the factors that influence population dynamics vary with weather. The challenge is even greater for game specie, as other human factors must be considered. The wild turkey naturally expanded its distribution northward into southern Quebec, without humans transplanting turkeys from other regions. However, the northern expansion is currently limited by extreme weather events. We used matrix modelling to explore the respective and interactive effects of weather and harvest levels on demographic parameters of three populations at different expansion stages but all at the northern edge of the species distribution. Our results suggest that populations at the expansion front (fast-paced life history) can sustain higher hunting rates than well-established populations (slow-paced life history), but that the proportion of adult males declines more rapidly in response to a given level of harvest. Furthermore, populations at the expansion front under harsh to extreme conditions could not tolerate any level of harvest. Finally, fall hunting had the greatest influence on population dynamics mainly because harvesting of all females is permitted, while spring hunting is restricted to bearded birds only (<1% of turkeys harvested in spring are bearded hen). Optimal hunting regimes for populations at the limit of their distribution vary with weather and expansion stages. A conservative solution would be to allow fall hunting only in well-established populations, but adaptive management where fall harvest at the expansion front would be implemented during more mild winters. Our model approach is relatable to the very many populations currently expanding poleward in response to climate change by considering different adaptive management policies in established and expanding populations.

Integrating Ecofeminism Into Canadian Nursing to Tackle Climate Change and Health Issues.

Nursing inquiry, 32(3):e70035.

This paper presents an overview of the health impacts associated with anthropogenic climate change and examines the interconnection between human health and the environment. It highlights the nursing profession's stance on environmental issues, drawing attention to the disengagement of nurses from advocacy initiatives related to climate change and how this relates to the nursing metaparadigm. Moreover, this paper supports a multidirectional approach to address climate change solutions, with a particular emphasis on both adaptation and mitigation strategies. Ecofeminism is proposed as a critical framework to address the shortcomings of the metaparadigm and the approaches to climate change solutions. It examines the potential for integrating ecofeminism into nursing research and practice by reconceptualizing the concept of the environment, adopting an ethic of the environment, and critiquing oppressive social structures. The benefits of ecofeminism for nursing include enhancing nurses' responsiveness to the health consequences of climate change, facilitated by using a critical voice that promotes inclusion and collective action.

Ruminant livestock and climate change: critical discourse moments in mainstream and farming sector news media.

Agriculture and human values, 42(2):945-964.

UNLABELLED: There is ongoing contestation around greenhouse gas emissions from ruminant livestock and how society should respond. Media discourses play a key role in agenda setting for the general public and policymakers, and may contribute to polarisation. This paper examines how UK news media portrayed ruminant livestock's impact on climate change between 2016 and 2021. The analysis addresses a gap in the literature by comparing discourses in national and farming sector newspapers using a qualitative approach. Four national and two farming sector news outlets were searched for articles published between 2016 and 2021. A corpus of 996 relevant articles was assembled, from which 154 were selected for in-depth examination using Critical Discourse Analysis. Four 'Critical Discourse Moments' (CDMs), each signifying a discursive shift in the debate, were identified over the 6-year studied period: 1) Low salience, diverging discourses, 2) We must eat far less meat, 3) Fighting the anti-meat agenda, and 4) Policy (in)action at COP26. There was a large increase in the number of published articles from January 2019 onward, partly associated with publication of the EAT/Lancet Commission report. CDM 2 (We must eat far less meat) occurred mainly in the national media, while CDM 3 (Fighting the anti-meat agenda) occurred mainly in the farming media. Our findings reveal both opinion polarisation and intergroup polarisation between national and farming sector media, and low engagement with food system power imbalances. Addressing polarisation will be important to enhance capacity for collective decision-making regarding methane emissions from ruminant livestock.

Climate change skepticism of European farmers and implications for effective policy actions.

Communications earth & environment, 6(1):396.

European farmers struggle with mitigating global emissions of greenhouse gases effectively and to cope with climate change. European regulators and national governments encounter obstacles in implementing environmental policies, feeding frustration amongst farmers. We hypothesize that these issues relate to climate change skepticism within the farming community and dissensus with non-farmers and between countries. To test this hypothesis, we analyzed climate attribution and impact skepticism amongst farmers and the rest of the working population using the Eurobarometer and the European Social Survey, and national data about gross domestic product (GDP), innovativeness, share of agricultural land, and climate damage risk for agriculture. Impact skepticism of farmers increases with decreasing risk of climate damage and increasing GDP, causing a South-North gradient in Europe. The majority of farmers in the EU countries were more skeptical than non-farmers. Understanding and reducing this skepticism provides a key to more effective mitigation and adaptation.

Evolutionary Genomics Unravels the Responses and Adaptation to Climate Change in a Key Alpine Forest Tree Species.

Molecular biology and evolution pii:8148825 [Epub ahead of print].

Despite widespread biodiversity loss, our understanding of how species and populations will respond to accelerated climate change remains limited. In this study, we integrate population genomics, experimental evolution, and environmental modeling to elucidate the evolutionary responses to climate change in Populus lasiocarpa, a key alpine forest tree species primarily distributed in the mountainous regions of a global biodiversity hotspot. Over historical timescales, our findings demonstrate that demographic dynamics, divergent selection, and long-term balancing selection have shaped and maintained genetic variation within and between populations. In examining genomic signatures of contemporary climate adaptation, we found that haplotype blocks, potentially caused by inversion polymorphisms that suppress recombination, are linked to enriched combinations of locally adaptive environmental variations. We further assessed the relative contributions of environmentally induced plastic responses, constitutive expression divergence between genetic clusters, and their interactions in driving gene expression variation and divergence. Notably, we observed a strong correlation between sequence divergence and constitutive differential expression among genetic clusters. Finally, by incorporating genetic adaptation, migration, and genetic load into our predictions of population-level climate change risks, we identified western populations-primarily distributed in the Hengduan Mountains, a region known for its environmental heterogeneity and significant biodiversity-as the most vulnerable to climate change. These populations should be prioritized for conservation and management. Overall, our study advances the understanding of the relative roles of long-term natural selection, local environmental adaptation, and immediate plastic expression changes in shaping the responses of natural populations of keystone species to climate change.

Modeling vegetation dynamics in complex topography under impacts of climate change: Integration of spatial clustering and optimized XGBoost.

Journal of environmental management, 387:125902 pii:S0301-4797(25)01878-X [Epub ahead of print].

Understanding vegetation dynamics under impacts of climate change is essential for assessing ecosystem services, particularly in vulnerable areas. This study presents an efficient and accurate method for projecting the Normalized Difference Vegetation Index (NDVI) to evaluate environmental status influenced by climate change, focusing on the Karkheh watershed, an ecologically sensitive area with complicated topography in Iran. We optimized a XGBoost model with Particle Swarm Optimization (PSO) to estimate monthly spatiotemporal dynamics of NDVI, effectively handling extensive pixel-level time series data and capturing nonlinear relationships. After downscaling climate data from the Coupled Model Intercomparison Project phase 6 (CMIP6) using the Statistical Downscaling Model (SDSM), historical and future precipitation and temperature maps were generated through optimal Geographically Weighted Regression (GWR). The model incorporated 23 input variables, including phenological rhythm categories, meteorological factors (with various time lags), and seasonal cycles, to project NDVI from 2030 to 2050 under various Shared Socioeconomic Pathways (SSP) scenarios. Results demonstrate that the optimized XGBoost model effectively evaluates vegetation growth, with the Nash-Sutcliffe Efficiency (NSE) of 0.93 and NDVI is projected to increase across all future scenarios, particularly under higher emissions pathways. SHapley Additive exPlanation (SHAP) analysis reveals that phenological rhythms, moderate temperatures from the preceding month, moderately high current temperatures, and high precipitation from four months earlier play key roles in NDVI projection for this watershed.

Future projections of thermal and chemical stratifications in reservoir under the impact of climate change.

The Science of the total environment, 984:179722 pii:S0048-9697(25)01363-4 [Epub ahead of print].

Vertical stratification is a fundamental characteristic of water bodies that significantly affects vertical convection and mixing dynamics. With the impact of climate change, thermal and chemical stratification in lakes and reservoirs has been exacerbated, leading to more pronounced environmental and ecological challenges. While previous studies have identified the impact of climate change on reservoir stratification, they have primarily focused on temperature variations in future periods. This study goes beyond temperature and the direct outputs of General Circulation Models (GCMs) by also considering inflow volume and temperature, providing a more comprehensive assessment of climate change effects on both thermal and chemical stratification. To do so, this study developed a two-dimensional hydrodynamic model, i.e., CE-QUAL-W2, to investigate the thermal and chemical responses of the Wadi Dayqah Reservoir, located in Oman, to projected climate change. The results indicated that under the SSP1-2.6 scenario, the annual mean inflow temperature remained largely unchanged, whereas the SSP2-4.5 and SSP5-8.5 scenarios induced significant increases. Additionally, climate change led to a prolonged persistence of summer thermal and chemical stratification, with the most substantial delay occurring under the SSP5-8.5 scenario. Moreover, the SSP5-8.5 scenario exhibited a significantly higher frequency of critical chemical index occurrences than SSP2-4.5 and SSP1-2.6, highlighting the strong interdependence between thermal and chemical stratification in reservoir systems. Under SSP1-2.6, SSP2-4.5, and SSP5-8.5, thermal stratification (SI) is expected to rise by 12 %, 26 %, and 43 % by the end of the century. The chemical stratification index (CI) is anticipated to climb by 9 %, 21 %, and 38 % in the same scenarios, indicating higher warming routes intensifying stratification. These findings emphasize the urgent need for emission reduction strategies to mitigate climate-induced warming, maintain thermal stability, and protect reservoir ecosystems from extreme stratification under future climate scenarios.

Conserving the critically endangered Hangul (Cervus hanglu hanglu)-future distribution and efficiency of protected areas under climate change.

Environmental monitoring and assessment, 197(6):672.

Climate change is impacting species distribution at a global scale, posing a significant threat to biodiversity. Special attention needs to be given to threatened species like the Kashmir Red Deer (Cervus hanglu hanglu). Despite being a symbol of global conservation, holistic management is necessary for decision-making and species recovery. A comprehensive study mapping of the potential habitat changes for Hangul in the Dachigam landscape is crucial to enhance conservation efforts. We examined the impacts of expected global warming on the distribution of Hangul by employing a maximum entropy approach to assess species range shift. Hangul was anticipated to be sensitive to upcoming worldwide warming, and it was expected that this would increase its risk of local extinction. In the model, the severity of repercussions from climate change grew as the time horizon increased and decreased the species' suitable habitat. By 2080, predictions indicated a gradual reduction in range or, in some scenarios, the complete loss of habitat, regardless of the potential for Hangul to disperse indefinitely. We estimated that the overall very highly suitable habitat in the protected region is currently 2220 ha, while its vast distribution area in the unprotected zone is 30,445 ha, emphasizing the necessity of establishing corridor connectivity between fragmented populations and promoting conservation efforts. Among various climate conditions, the core-to-edge ratio is at its highest level in the current conditions. Our study reveals two critical findings: Firstly, endangered species unique to a particular region are highly susceptible to the impacts of global warming. Secondly, when evaluating the outcomes of global warming, the highly suitable habitat is expected to shift under predicted climatic changes, with an average altitudinal migration of 700 m. Consequently, conservation strategies must consider the expected regional shifts and are designed with a clear understanding of the accuracy of projecting climate change effects.

Factors affecting the responses of rice quality to global warming in the field conditions: a meta-analysis.

Journal of the science of food and agriculture [Epub ahead of print].

BACKGROUND: Global warming has been suggested to have negative impacts on most quality traits of rice; however, factors and how they affect the responses of rice quality to warming still need systematic examination under field conditions.

RESULTS: In this study, we conducted a meta-analysis to evaluate the overall impacts of field warming on grain quality and identify the key factors affecting these impacts, collecting data from 45 published studies with 1316 paired observations. Our results found that warming significantly increased chalkiness degree, chalky rice rate, protein content and breakdown value, but decreased head rice rate and amylose content. Growth stage when warming was imposed had significant impacts on the grain quality responses to warming, with larger responses generally observed at reproductive stage than vegetative stage; besides, warming responses of grain quality also significantly differed among warming patterns and subspecies. Importantly, our results suggest that deterioration of appearance quality under warming tends to decrease with increasing soil fertility. However, with the increasing N and P applications and panicle N percentage, negative responses of milling and appearance qualities to warming become more severe. Additionally, our results suggest that negative responses of appearance quality to warming could be mitigated by increasing K application.

CONCLUSION: Our present findings should further our understandings of the warming effects on rice quality under field conditions and be helpful in mitigating the negative effects of warming on grain quality by variety selection, amelioration of soil fertility and optimal inorganic fertilizer inputs. © 2025 Society of Chemical Industry.

Modeling the influence of global warming on carbon, phytoplankton, and zooplankton dynamics.

Scientific reports, 15(1):17911.

Over the last 250 years, anthropogenic activity has increased atmospheric carbon dioxide by nearly 40%. This increase is mainly caused by human fossil fuel combustion and deforestation, which are the main causes of global warming. Phytoplankton of the world's oceans synthesizes half of the carbon dioxide of the total Earth's photosynthetic activity. Thus, phytoplankton plays a crucial role in controlling Earth's climate. To study this scenario, we propose and analyze a mathematical model for the carbon-phytoplankton-zooplankton interaction dynamics. Positivity, boundedness, existence, and stability of biologically possible equilibrium points are studied. The system exhibits Hopf bifurcation with respect to the carbon capture coefficient and the criteria of Hopf bifurcation is established around the coexisting equilibrium. Complex spatiotemporal dynamics and patchy pattern formation are observed in the spatially explicit model. The proposed carbon-phytoplankton-zooplankton system incorporates the effect of global warming, and our simulation shows shifts in plankton seasonal dynamics.

Prediction of the potentially suitable areas of Elymus dahuricus Turcz in China under climate change based on maxent.

Scientific reports, 15(1):17959.

Elymus dahuricus Turcz (E.dahuricus) is an excellent forage grass with very high economic value and high adaptability.Predicting the potential habitat distribution of E.dahuricus in China can provide solid and scientific theoretical support for the effective utilization of E.dahuricus germplasm resources.In this study, 180 occurrence sites of E.dahuricus and 38 environmental variables were selected, and the optimized Maxent model and ArcGIS V10.8 software were used to simulate and predict the potential distribution areas of E.dahuricus in China for the present (1970-2020),2050s (2041-2060) and 2090s (2081-2100). The results showed that (1) the simulated AUC value of MaxEnt model is 0.850,with high simulation accuracy; (2)Temperature seasonality(bio4),min temperature of coldest month(bio6),precipitation of driest quarter(bio17),precipitation seasonality(bio15),cation exchange capacity of topsoil(t_cec_soil) and altitude(elev) were the main environmental factors affecting the distribution of E.dahuricus; (3)Presently, the suitable habitats were mainly distributed in Xinjiang, Xizang, Gansu, Qinghai, Ningxia, Inner Mongolia, Shanxi, Hebei, Beijing, Liaoning, Chongqing and other provinces.According to our results that the total suitable habitat area will increase under future climate scenarios and the general trend of mass center toward higher latitude.Our results provide wild resource information and theoretical reference for the protection and rational utilization of E.dahuricus.

Spatial and temporal patterns of lichen occurrence indicate shifts in atmospheric pollution and climate change - A case study from Bremen, North-Western Germany.

Environmental pollution (Barking, Essex : 1987), 378:126465 pii:S0269-7491(25)00838-3 [Epub ahead of print].

Lichens are used as bioindicators of air pollution and climate change. Despite a few studies from central Germany and the neighbouring Netherlands, the north German lichen flora remains poorly known. In this study we aimed to examine the occurrence of lichens in relation to various environmental drivers and to assess the temporal changes in the lichen flora in response to altered air pollution and climate change. We examined the abundance of epiphytic lichen species in relation to tree characteristics in the city of Bremen in north-western Germany. Trees distributed across 30 grid squares throughout the city were sampled according to the VDI-guideline (3957-13, 2023). The lichen flora was also compared to species lists for Bremen from 1985 and 1995. Tree circumference had significant effects on the abundances of the majority of single species and on total species richness. Most lichens preferred the southern and western sides of the trees and trees of the genera Quercus and Fraxinus (compared to Tilia and Betula). The cumulative number of lichen species had increased since 1985 more than 4 times, while the species composition had changed towards a community of more nitrophytic and fewer acidophytic species, reflecting the current changes in air pollution. Climate change indicator species had increased from zero (1985) to seven (2024), and the mean Ellenberg values indicated a shift towards a lichen flora of more Atlantic species. Our study emphasizes the importance of lichens as bioindicators to track changes in air pollution and climate.

The dynamics of wild Vitis species in response to climate change facilitate the breeding of grapevine and its rootstocks with climate resilience.

Horticulture research, 12(7):uhaf104.

Climate change presents significant challenges to agricultural suitability and food security, largely due to the limited adaptability of domesticated crops. However, crop wild relatives maintain greater diversity and are well adapted to various environments. This study evaluates the potential distributional responses of grapevine (Vitis vinifera L.) and its wild relatives (Vitis spp.) to future climate change using the maximum entropy model. We reveal that the annual mean temperature is the primary factor determining the potential distribution of cultivated grapes. By 2080, under the SSP585 scenario, suitable areas for wine and table grapes are predicted to decline by 1.5 million and 1.3 million km [2], respectively. The results suggest that grape cultivation, especially for table grapes, is highly vulnerable to future climate change. In contrast, approximately 70% of wild grapes are projected to demonstrate robust adaptability to future conditions. For example, wild grapes from North America, such as Vitis rotundifolia and Vitis labrusca, and from East Asia, such as Vitis heyneana and Vitis davidii, are projected to demonstrate significant adaptability in response to future climate change. These wild grapes are valuable genetic resources for improving the resilience of cultivated grapes through rootstock development and breeding programs to face the climate change. Our results predict the potential future distribution areas of wild grapes and highlight the critical role of their genetic resources in grape breeding for promoting adaptation to climate change.

Effects of climate change on stream temperature and salmonid habitats in a Cascades river basin.

Journal of environmental management, 387:125843 pii:S0301-4797(25)01819-5 [Epub ahead of print].

Rising stream temperatures pose significant challenges to aquatic ecosystems, particularly for coldwater-adapted organisms like salmonids. This study examines the effects of climate change on stream temperatures and salmonid habitats in the Clackamas River Basin, Oregon, USA. Using spatial stream network models and CMIP6 climate projections under SSP2-4.5 and SSP5-8.5 scenarios, we project mid- (2045-2074) and late-century (2075-2100) stream temperature changes. These projections are then integrated with thermal tolerances and intrinsic habitat metrics to assess future habitat suitability for key species, including steelhead, coho, Chinook, and bull trout. Stream temperature trends from 1991 to 2023 reveal basin-wide warming, with high-elevation tributaries demonstrating more resilience to climate impacts while lower-elevation subwatersheds face greater vulnerability. Future projections indicate a basinwide maximum 7-day average of daily maximum stream temperature increases of 1.42 °C-2.04 °C for the midcentury, and 1.84 °C-3.24 °C by the end of the 21st century. These increases reduce the most thermally suitable habitats for steelhead, coho, Chinook, and bull trout by an average of 27 %-36 % during the mid-century time period, and 35 %-51 % by the end-of-century time period. By linking climate-driven temperature projections with habitat metrics, we identify priority subwatersheds based on projected thermal suitability where conservation efforts can maximize impact.

OBJECTIVE: To understand health professionals' perceptions of climate change and its impact on health and their perceived role.

STUDY DESIGN: This was a systematic review of qualitative studies.

METHODS: A systematic review of qualitative evidence from three databases (MEDLINE, CINHAL and PsycInfo) was conducted according to the Cochrane method in June 2024. The PRISMA 2020 guidelines were followed for the synthesis report.

RESULTS: A total of 215 results were obtained, of which 10 studies were included on the basis of the inclusion criteria. The selected studies included predominantly nurses, physicians and public health professionals, with a smaller representation of other allied health professionals from Europe, North America and Africa. These studies were published between 2015 and 2024. Three themes were identified: "general knowledge of climate change", "role of health professionals in addressing climate change" and "barriers to action on climate change". Health professionals are aware of the health risks posed by climate change, but some barriers prevent or hinder their action. The main barriers are poor, overly generalised information and training, and a demotivating environment.

CONCLUSION: Health professionals are aware of the existence and dangers of climate change but are less aware of their role in the face of climate change. Contextualised training and an enabling environment are needed. It is essential to study the perceptions of each group of health professionals at the national or subnational level.

Across two studies using primary data (n = 3,653 adult participants; 11 countries) and secondary data (ns = 60,230 and 22,496 adult participants; 55 countries), we tested (a) the generalizability of pluralistic ignorance about climate-change beliefs, (b) the effects of a public-consensus intervention on climate action, and (c) the possibility that cultural tightness-looseness might serve as a country-level predictor of pluralistic ignorance. In Study 1, people across 11 countries underestimated the prevalence of proclimate views by at least 7.5% in Indonesia (90% credible interval, or CrI = [5.0, 10.1]), and up to 20.8% in Brazil (90% CrI = [18.2, 23.4]. Providing information about the actual public consensus on climate change was largely ineffective, except for a slight increase in willingness to express one's proclimate opinion, δ = 0.05 (90% CrI = [-0.02, 0.11]). In Study 2, pluralistic ignorance about willingness to contribute financially to fight climate change was slightly more pronounced in looser than tighter cultures, highlighting the particular need for pluralistic-ignorance research in these countries.

Emotions and climate change: The role of emotion regulation in climate action.

Emotion (Washington, D.C.) pii:2026-19037-001 [Epub ahead of print].

Although there is strong evidence for the role of emotion in climate change-mitigating behaviors (Brosch, 2021), little is known about the role of emotion regulation in climate action (Panno et al., 2015). Our studies (a correlational study and an experiment, conducted in 2022) investigated the role of emotion regulation in emotional responses to climate change and the likelihood of taking climate change-mitigating actions. In Study 1, 151 participants from the United States and Canada read about the detrimental effects of climate change before recording their emotional responses, emotion regulation strategies used in response to climate change information, and climate actions (proenvironmental behaviors and civic engagement in environmental actions). Some emotion regulation strategies predicted climate action, including when controlling for demographic variables. In Study 2, 245 participants from the United States watched a video on the negative consequences of climate change, rated their emotions, and were randomly assigned to distraction, worrying, or positive reappraisal in response to the video. Next, they were given the option to sign an environmental petition and donate money to an environmental organization before rating their intentions to engage in climate actions. Distraction reduced negative emotion, and positive reappraisal increased hope. The effects of emotion regulation on engagement in climate action were mixed. Exploratory mediation analyses indicated that worrying and reappraisal increased intentions to engage in climate action via negative emotion. Further experimental research on the effects of emotion regulation on climate action will be important for informing communications about climate change to protect mental health while motivating action.

Optimistic bias in updating beliefs about climate change longitudinally predicts low pro-environmental behaviour.

The British journal of social psychology, 64(3):e12905.

We investigated the preregistered hypothesis that an optimistic bias in updating beliefs about climate change (i.e., integrating good news more than bad news) cross-sectionally (NStudy 1 = 109) and longitudinally (NStudy 2 = 407) predicts self-reported pro-environmental behaviour (PEB). To test this, we employed an experimental task in which participants were presented with multiple climate change scenarios and asked to update their beliefs after receiving scientific evidence. Additionally, we investigated whether biased belief updating and PEB could be altered by brief experimental interventions providing information on different aspects of climate change. Results show that optimistically biased belief updating did not predict PEB cross-sectionally, but did predict PEB 4 weeks later, while controlling for baseline levels of PEB. The experimental interventions did not significantly alter belief updating or increase PEB, although there were significant gender differences. The results suggest that an optimistic bias in belief updating longitudinally predicts low engagement in PEB, possibly because selectively integrating good news over bad news reduces the perceived urgency to take action. Yet the effect may be small and detectable only in sufficiently large samples. The results also indicate that it is challenging to modify this bias. Implications for research on attitude change, social cognition and PEB are discussed.

Predicting current and future potential distribution of Changnienia amoena in China under global climate change.

Scientific reports, 15(1):17640.

Changnienia amoena is a terrestrial orchid endemic to China and holds significant ornamental and medicinal value. Understanding the current and future potential geographic distribution patterns of C. amoena under climate change is crucial for its effective conservation and sustainable development. This study uses 48 distribution records and 19 environmental variables to simulate and predict the potential distribution and spatial pattern changes of C. amoena under different future gas emission scenarios (SSP1-2.6, SSP2-4.5, and SSP5-8.5) for both the 2050s and 2090s. The dominant environmental variables influencing its distribution were also identified. The MaxEnt model yielded an AUC of 0.990 and CBI of 0.959, indicating extremely high predictive accuracy. The key environmental variables influencing the distribution of C. amoena include the minimum temperature of coldest month (Bio06), annual precipitation (Bio12), isothermality (Bio03), land use classification, slope, topsoil USDA texture classification, elevation, and topsoil calcium carbonate. Among these, temperature and precipitation have relatively significant impacts on the distribution of C. amoena. Under the SSP1-2.6 scenario, the suitable habitat for C. amoena shows a slight contraction, while under the SSP2-4.5 and SSP5-8.5 scenarios, the suitable habitat shifts and expands significantly towards the northwest, higher latitude and altitude areas. This research has important scientific significance and practical guidance value for the in-situ conservation, ex-situ cultivation, and sustainable utilization of C. amoena.

Evaluating the impact of climate change on hurricane wind risk: A machine learning approach.

Risk analysis : an official publication of the Society for Risk Analysis [Epub ahead of print].

In the residential sector, hurricane winds are a major contributor to storm-related losses, with substantial annual costs to the US economy. With the potential increase in hurricane intensity in changing climate conditions, hurricane impacts are expected to worsen. Current hurricane risk management practices are based on the hurricane risk assessment without considering climate impact, which would result in a higher level of risk for the built environment than expected. It is crucial to investigate the impact of climate change on hurricane risk to develop effective hurricane risk management strategies. However, investigation of future hurricane risk can be very time-consuming because of the high resolution of the models for climate-dependent hazard simulation and regional loss assessment. This study aims to investigate the climate change impact on hurricane wind risk on residential buildings across the southeastern US coastal states. To address the challenge of computational inefficiency, we develop surrogate models using machine learning techniques for evaluating wind and rain-ingress losses of simulated climate-dependent hurricane scenarios. We collect historical hurricane data and use selected climate variables to predict changing hurricane attributes under climate change. We build the surrogate loss model using data generated by the existing fragility-based loss model. The loss estimation of synthetic events using the surrogate model shows an accuracy with a 0.78 R-squared value compared to Hazard U.S. - Multi Hazard (HAZUS-MH) estimation. The results demonstrate the feasibility of utilizing surrogate models to predict risk changes and underline the increasing hurricane wind risk due to climate change.

Assessing ozone pollution and climate change impacts on winter wheat: flux modeling vs. dose-response modeling.

Journal of environmental management, 387:125767 pii:S0301-4797(25)01743-8 [Epub ahead of print].

Surface ozone is a phytotoxic pollutant that damages photosynthetic systems, reduces gas exchange, retards vegetation growth, and decreases yield. In this study, we developed a new ozone flux module within an agroecosystem model framework to enhance our ability to understand, measure, and predict the impact of surface ozone on agricultural productivity. The new module was calibrated and evaluated against historical observational data from multiple sites. It was then applied to predict winter wheat yield and gross primary productivity (GPP) in response to future ozone changes under different climate scenarios. The new ozone flux model was more sensitive to ozone concentration changes than the ozone dose-response model, demonstrating greater GPP and yield losses at the same ozone pollution level. We also investigated several key environmental factors (temperature, precipitation, carbon dioxide) and their synergistic effects with and without ozone to explore the complexity of ozone pollution impacts under climate change. The simulation results indicate a worsening food crisis, driven by interannual trends in crop losses from ozone pollution under high- and moderate-emission scenarios. A more accurate understanding and qualification of ozone's effects on crop growth and yield is essential for safeguarding food security.

The effect of climate change on glyphosate control of Avena fatua, Brassica napus, and Echinochloa crus-galli.

The Science of the total environment, 983:179682 pii:S0048-9697(25)01323-3 [Epub ahead of print].

Atmospheric CO2 concentrations and temperatures have significantly increased, accompanied by substantial changes in precipitation patterns. These changes are anticipated to intensify in the future. In Nordic regions, increasing temperatures can improve growing conditions for some crops by extending the growing season and expanding cultivation northward. Climate changes may also favour some weed species, potentially reducing crop yield and affecting herbicide efficacy. To assess glyphosate efficacy under future climate conditions, we conducted two dose-response experiments on barnyard grass (Echinochloa crus-galli- C4 plant), oilseed rape (Brassica napus- C3 plant) and wild oat (Avena fatua- C3 plant). Plants were grown under ambient conditions (400 ppm CO2 at 18/12 °C (day/night)) and predicted future conditions (800 ppm CO2 at 20.5/14.5 °C (day/night)). Glyphosate was applied at 3-4 - leaf-stage in doses of 0, 8.75, 17.5, 35, 70, 140, 420, 1260, and 2520 g active ingredient (a.i.) ha[-1], with the highest dose only included in the second experiment. Chlorophyll fluorescence was measured 48 h after spraying. Two days after spraying, oilseed rape exhibited stress symptoms under both growing conditions, while barnyard grass showed symptoms only under future conditions and doses exceeding 6 g a.i. ha[-1]. Plants were harvested 72 h after spraying for transcriptome analysis and two weeks after spraying to determine dry weight, C%, N% and C/N ratio. The ED50 and ED90 values did not significantly differ between the two environments for each grass species. However, oilseed rape required significantly higher glyphosate doses to reduce dry weight by 50 and 90 % at ambient growing conditions, likely due to the faster translocation of glyphosate. This suggests that glyphosate doses can be reduced in a warmer climate with an elevated CO2 level. No apparent differences in the C%, N%, or C/N ratio were observed between environments for any species. Transcriptome analysis indicated that all species respond differently to glyphosate and climate change.

Evaluation of climate change mitigation strategies for Irish forests using the CBM-CFS3 model.

Carbon balance and management, 20(1):10.

BACKGROUND: The Irish Forestry greenhouse gas (GHG) profile is undergoing a transition from a net sink to net emission because of persisting emissions from organic soils, an increase in harvest and shifts in the age class structure of plantation forests. The forestry GHG trend diverges from the required National and European Union (EU) policy pathway for land use land use change and forestry (LULUCF) and agriculture aimed at halving emissions by 2030 and achieving carbon neutrality by 2050. A recalibrated version of the Carbon Budget Model of the Canadian Forest Service (CBM-CFS3) was used to assess the impact of identified national forest policy measures on the forest GHG profile over the short to long term.

RESULTS: An analysis of projected scenarios revealed that, under current silvicultural practices and afforestation policies (with existing measures-WEMs), Irish forests will continue to be a long-term emission beyond 2070 unless harvest rates and management practices are adjusted to negate the adverse impact of emissions from organic soils and fluctuations in historic afforestation rates. The implementation of additional measures (WAM) suggests that the forest sink can be sustained if harvest rates exceed 75% of the net annual increment (NAI), additional afforestation targets are met and if plantation rotation age is increased. Although additional afforestation and a reduction in deforestation is required to meet long-term carbon-neutral goals, the implementation of these policies has a minimal short-term impact on the 2030 targets set out under the National Climate Change Plan (CAP 24) and the revised EU LULUCF regulation (841/2023).

CONCLUSION: The results show that the extension of rotation age and associated reductions in harvest levels will have the greatest short-term impact on climate change mitigation, which can be delivered at a negative marginal abatement cost. However, even if WAM forest measures are implemented, Ireland is unlikely to meet the National and EU LULUCF targets by 2030 because of a decreasing forest sink.

Potential geographic displacement of Chagas disease vectors under climate change.

Medical and veterinary entomology [Epub ahead of print].

Climate change is projected to profoundly alter global biodiversity with significant implications for vector-borne disease dynamics. In tropical regions, rising temperatures and shifting precipitation patterns influence the distribution and behaviour of insect disease vectors, thereby affecting disease transmission cycles. Chagas disease, caused by the Trypanosoma cruzi and transmitted by triatomine bugs, is a major public health concern in Latin America. Brazil is particularly vulnerable to climate-driven vector redistribution due to its vast land area, diverse ecosystems and rapid land-use changes. Using ecological niche modelling and 11,640 unique occurrence records, we assessed the potential geographic displacement of 55 triatomine species under two climate scenarios: a moderate warming scenario (SSP2-4.5) and a high-emissions scenario (SSP5-8.5) for 2050 and 2080. While projections for 2050 suggest stability in vector distributions, our models indicate a substantial shift by 2080, with increasing suitability for vector populations in the Brazilian Amazon, particularly in the deforestation arc. This expansion could exacerbate Chagas disease risk in previously unaffected regions, where socioeconomically vulnerable populations face poor housing conditions that facilitate vector-human contact. Our findings underscore the urgent need for proactive vector surveillance, public health interventions and climate-adaptive disease prevention strategies to mitigate potential epidemiological risks associated with climate change.

Adolescents' agency toward climate change: development and validation of scales for individual, proxy, and collective modes.

Frontiers in psychology, 16:1532409.

In a rapidly evolving world, human agency serves as a driving force to shape a more sustainable future. The climate crisis is an example of how individuals must be proactive and take action to mitigate this environmental problem through three modes of agency advocated by Bandura: individual, proxy, and collective. This is even more relevant for adolescents, who will most suffer climate change consequences. However, instruments assessing adolescents' agency modes toward climate change are still lacking. To address this gap, we present the development and validation of three theoretically based scales for assessing each mode of adolescents' agency toward climate change (AGENTC2). The AGENTC2-Scales were developed based on a literature search, expert review, and consultation with a panel of adolescents. The AGENTC2-Scales were then empirically tested with 1,114 adolescents, and their psychometric properties were assessed, providing evidence of validity (i.e., content, structural, and convergent), measurement invariance (sex and school grade), internal consistency, and test-retest reliability. Data showed that the AGENTC2-Scales can be used to measure each mode of agency toward climate change and their properties validly and reliably. Further research is needed to extend the validation of the scales in other countries.

Assessing the impact of climate change on the potential distribution of Keteleeria evelyniana Mast. in southwest China: a Maxent modeling approach.

Frontiers in plant science, 16:1561031.

Keteleeria evelyniana Mast., which is widespread in southwestern China, is valuable for studying under different future climate scenarios to assess potential distribution shifts in response to climate warming. Understanding these changes can provide theoretical support for species conservation, rational utilization, ecological restoration, and management of K. evelyniana habitats. The Maxent model was optimized using the package of ENMeval to adjust the Regularization Multiplier (RM) and Feature Class Combinations (FC) parameters. Utilizing 221 effective distribution points and 33 environmental variables, the potential distribution of K. evelyniana in current and future climate scenarios was predicted, with the key environmental variables analyzed. The model with FC = LQ and RM = 0.5, demonstrated low complexity, minimal overfitting, and high accuracy, achieving an AUC value of 0.946 with a standard deviation of 0.011. Under the current climate conditions, 68% of the suitable areas for K. evelyniana were focused on Yunnan Province, with additional areas in western and southwestern Guizhou, southwestern Sichuan, and the southeastern Xizang Autonomous Region. In various future climate scenarios, the suitable areas for K. evelyniana gradually decreased, with a maximum reduction of 33%. Simultaneously, the centroids of these areas are expected to migrate northward by up to 33 km. Temperature was the dominant factor affecting its distribution (77.8%), whereas the effects of soil variables and altitude were significant. This study clarified the current distribution of K. evelyniana, projected the potential shifts under different future climate scenarios, and identified the main environmental factors affecting the distribution. These findings offer valuable theoretical support for the conservation, ecological restoration, and sustainable use of K. evelyniana.

Forecasting range shifts of dioecious plants under climate change.

Proceedings of the National Academy of Sciences of the United States of America, 122(21):e2422162122.

Global climate change has triggered an urgent need for predicting the reorganization of Earth's biodiversity. For dioecious species (those with separate sexes), it is unclear how commonly unique climate sensitivities of females and males could influence projections for species-level responses to climate change. We developed demographic models of range limitation, parameterized from geographically distributed common garden experiments, with females and males of a dioecious grass species (Poa arachnifera) throughout and beyond its range in the south-central U.S. We contrasted predictions of a standard female-dominant model with those of a two-sex model that accounts for feedbacks between sex ratio and vital rates. Both model versions predict that future climate change will induce a poleward shift of niche suitability beyond current northern limits. However, the magnitude of the poleward shift was underestimated by the female-dominant model because females have broader temperature tolerance than males but become mate-limited under female-biased sex ratios, which are forecasted to become more common under future climate. Our results illustrate how explicitly accounting for both sexes can enhance population viability forecasts and conservation planning for dioecious species in response to climate change.

Diagnostic Value of Botryoid Nuclei as a Biomarker of Severe Hyperthermia and Systemic Inflammation in Heatstroke and Neuroleptic Malignant Syndrome: A Challenge of Climate Change.

International journal of laboratory hematology [Epub ahead of print].

INTRODUCTION: With the increasing frequency of heat waves due to climate change, heat-related illnesses are becoming more common. Heatstroke is a life-threatening condition characterized by hyperthermia and multiple organ failure. A rare morphological feature, botryoid nuclei, has been identified in the peripheral blood of patients with hyperthermia, but its significance is not well understood. This study investigates the diagnostic value of botryoid neutrophils as a potential marker of severe hyperthermia and systemic inflammation in heatstroke and neuroleptic malignant syndrome.

METHODS: We performed a retrospective analysis of six patients with hyperthermia who were admitted to the Hospital Clínic of Barcelona and the Hospital de la Santa Creu i Sant Pau during the summers of 2023 and 2024. Peripheral blood smears were analyzed using CellaVision DM9600, MC-80, and DI60 analyzers. Blood cell counts were obtained using Advia 2120i and Sysmex XN analyzers. Biochemical parameters were measured using Atellica Solutions and Alinity analyzers.

RESULTS: Among the six cases, five were diagnosed with heatstroke and one with neuroleptic malignant syndrome. All patients exhibited botryoid nuclei in leucocytes (8% to 29%), more frequently observed in neutrophils. Hematologic findings included leucocytosis, neutrophilia with left shift, and thrombocytopenia. Biochemical analysis revealed significant organ dysfunction, including elevated liver enzymes, renal failure, and increased inflammatory markers, such as procalcitonin and lactic acid.

CONCLUSION: Botryoid-nuclei leucocytes may serve as a diagnostic marker for hyperthermia-related conditions, including heatstroke and neuroleptic malignant syndrome. This finding underscores the relevance of early recognition and intervention in patients presenting with hyperthermia and systemic inflammation.

[Impact of Climate Change and Human Activities on Vegetation Dynamics in Typical Lake Basins of China].

Huan jing ke xue= Huanjing kexue, 46(5):2987-2996.

Monitoring vegetation dynamics and isolating as well as quantifying the impacts of climate change and human activities on vegetation cover changes are crucial for providing theoretical support for maintaining regional ecological balance and scientifically planning ecological restoration. This study focuses on the Dongting, Poyang, and Taihu Lake basins. Using multi-temporal normalized difference vegetation index (NDVI) data, meteorological data, and land use data and employing methods, such as trend analysis, first-order difference multiple regression analysis, and residual analysis, this research investigates the spatiotemporal characteristics and driving mechanisms of vegetation NDVI changes in these basins from 2000 to 2022, distinguishing between natural growth areas and anthropogenic impact areas. The results indicate that from 2000 to 2022, vegetation in the Dongting, Poyang, and Taihu Lake basins, including both anthropogenic impact areas and natural growth areas, exhibited a greening trend. Overall, compared to precipitation and solar radiation, the NDVI of vegetation in the three major lake basins was more sensitive to temperature. Vegetation growth in these basins exhibited a consistently positive sensitivity to temperature, whereas it predominantly showed a negative sensitivity to precipitation. Climate change has promoted an increase in vegetation NDVI across the three lake basins. In anthropogenic impact areas, human activities predominantly drove the changes in vegetation NDVI, with the effects being bidirectional. Specifically, in the Dongting and Poyang Lake basins, human activities mainly had a positive impact on vegetation NDVI, whereas in the Taihu Lake Basin, the impact was predominantly negative.

Understanding climate change anxiety and anticipatory climate disaster stress: A survey of residents in a high-risk California county during wildfire season.

BMJ mental health, 28(1): pii:bmjment-2024-301331.

BACKGROUND: With the increasing prevalence of climate-related disasters, psychological responses, including climate change anxiety and anticipatory climate disaster stress, have received heightened attention.

OBJECTIVE: We investigate the correlates of climate change anxiety and anticipatory climate disaster stress, as well as the nature of these psychological responses.

METHODS: At the start of the annual fire season (June to August 2023), we recruited a county-representative sample of n=813 residents of Lake County, in Northern California, to complete an anonymous online survey. Multiple regression analyses identified correlates of climate change anxiety and anticipatory climate disaster stress and explored how anxiety and stress were associated with disaster preparedness.

FINDINGS: Climate change anxiety, assessed via its cognitive-emotional impairment (odds ratio (OR)loss/injury=1.68; ORmedia=2.37) and functional impairment (ORloss/injury=1.68; ORmedia=2.63) subfactors, and anticipatory climate disaster stress (bloss/injury=0.15, bmedia=0.26) were associated with previous wildfire-induced loss/injury and media exposure to wildfire-related content. Anticipatory climate disaster stress was also associated with the frequency of being in an evacuation zone (b=0.05). Both the cognitive-emotional impairment subfactor of climate change anxiety (incidence rate ratio (IRR)=1.23) and anticipatory climate disaster stress (IRR=1.14) were associated with preparing an emergency kit and power outage supplies; anticipatory climate disaster stress was associated with evacuation intentions should an actual fire occur (b=0.12).

CONCLUSIONS: Prior experiences with climate disasters could explain people's psychological responses to climate change. These responses could be temporally appropriate and functionally adaptive, given the immediacy of a potential fire.

CLINICAL IMPLICATIONS: Climate change anxiety and anticipatory climate disaster stress should not be oversimplified as typical clinical symptoms because their presence might motivate adaptive self-protective behaviours in the face of an upcoming disaster.

Climate crossroads: How global warming drives coronavirus emergence, the long COVID crisis of tomorrow, and AI's role in navigating our future.

Infectious diseases now pii:S2666-9919(25)00070-3 [Epub ahead of print].

This narrative review examines the critical nexus between climate change, coronavirus emergence, and Long COVID-a triad that may shape public health outcomes for generations. Climate change disrupts ecological balances that have historically limited viral spillover events, creating novel interfaces between wildlife reservoirs and human populations. The coronavirus family presents particular concern due to its diversity, adaptability, and demonstrated capacity for cross-species transmission. With over 200 coronaviruses identified in bat populations alone, this vast reservoir of genetic diversity, combined with the family's propensity for recombination, creates substantial pandemic potential that climate disruption may further amplify. Long COVID has revealed another dimension of the coronavirus threat: the potential for significant chronic disease burden following acute infection. This complex multisystem condition affects a substantial portion of SARS-CoV-2 infected individuals, with mechanisms including viral persistence, autoimmunity, microclot formation, and mitochondrial dysfunction. Future projections suggest that climate change could increase global viral spillover risk by 30-45% by 2070, particularly in Southeast Asia, Central Africa, and parts of South America. Artificial intelligence offers promising tools for addressing these interconnected challenges through enhanced surveillance, accelerated therapeutic development, and optimized healthcare delivery. Understanding the climate-coronavirus-chronic illness nexus has become essential to the development of resilient health systems and effective planetary health policies face to an uncertain future.

Exploring the Spatio-temporal Distribution Characteristics and the Impacts of Climate Change and Human Activities on Global Grassland Based on kNDVI.

Environmental research pii:S0013-9351(25)01135-1 [Epub ahead of print].

Grasslands provide essential resources and maintain ecological balance, yet about 40% of the world's grasslands have degraded due to climate change and human activities. To investigate the impact of these factors on global grassland coverage from 2001 to 2023, the Kernel Normalized Difference Vegetation Index (kNDVI) was calculated using the Google Earth Engine (GEE) platform. Spatio-temporal variations in global grassland kNDVI were analyzed with the Mann-Kendall mutation (M-K-M) test, Theil-Sen slope analysis, and the Mann-Kendall test. Partial correlation and residual analysis identified the factors influencing kNDVI changes. Results showed significant spatial heterogeneity in global grassland kNDVI, with higher values in the Southern Hemisphere and lower values in the Northern Hemisphere. Over time, global grassland kNDVI increased at a rate of 0.00043/a, with no significant mutation spots identified. However, significant mutations were detected in most Köppen climate zones except Am. Spatially, 34.57% of regions showed kNDVI degradation, while 65.43% improved. Driving factor analysis indicated that kNDVI was negatively correlated with mean annual temperature but positively correlated with total annual precipitation. Human activities positively impacted kNDVI in 73.25% of cases. The smallest area of degradation (5.80%) was due to human activity, while the least improvement (6.17%) resulted from climate change. In summary, we concluded that there has been a rising trend in the global grassland kNDVI. Changes in the vegetation coverage of grasslands around the world were caused by human activities and the effects of climate change. This study offered useful theoretical frameworks and data references for managing grasslands and restoring degraded areas.

Forecasting the Future Distribution of zataria multiflora in Iran Affecting by Climate Change: A MaxEnt Approach.

Integrated environmental assessment and management pii:8137841 [Epub ahead of print].

Climate change, driven by both natural and human influences, presents serious threats to biodiversity and the distribution of species over the coming decades. To examine the effects of climate change on species distribution and habitat suitability, researchers have widely employed Species Distribution Models (SDMs). This study specifically investigated Zataria multiflora, a valuable medicinal plant found in Iranian rangelands. The aim was to identify the critical factors influencing the distribution of Z. multiflora and assess how climate change may affect its range. The researchers utilized the Maximum Entropy Model (MaxEnt), incorporating eight environmental variables: maximum temperature of the warmest month, minimum temperature of the coldest month, annual temperature range, precipitation of the driest quarter, precipitation of the coldest quarter, depth to bedrock, slope, and solar radiation. The results indicated that solar radiation, slope, precipitation during the warmest quarter (bio17), and maximum temperature of the warmest month (bio5) were the most significant factors affecting the species' distribution. Projections suggest a potential decrease in the species' range by 43.98%, 51.60%, 54.20%, and 68.10% under RCPs 4.5-2050, 8.5-2050, 4.5-2070, and 8.5-2070, respectively. These insights can assist decision-makers in developing effective conservation strategies to protect and sustainably manage Z. multiflora in light of global climate change. Given the expected habitat loss, in-situ conservation efforts should be prioritized for the protection of Z. multiflora.

The health effects of climate change: identifying strategies, policies, and knowledge gaps: an umbrella review.

International journal of environmental health research [Epub ahead of print].

Climate change has emerged as a significant global challenge with profound implications for human health. This umbrella review synthesizes findings from systematic reviews and meta-analyses to examine the health impacts of climate change and identify strategies to mitigate these effects. This is an umbrella study conducted in major health and biomedical databases, including PubMed, ISI Web of Knowledge, Scopus, and Google Scholar, for articles published between 2011 and 2021. The search strategy followed the protocol published in BMJ Journal in 2020. The selected articles underwent a rigorous screening process based on predefined inclusion criteria. A total of 37 systematic review articles were included in the study. The thematic analysis identified a range of strategies and policies aimed at mitigating the health effects of climate change, including adaptation measures, public health interventions, and interdisciplinary collaborations. The analysis also revealed significant knowledge gaps in certain areas, highlighting the need for further research.

Spatio-temporal variation of climate productivity of vegetation and its responses to climate change in three provinces of Northeast China.

Ying yong sheng tai xue bao = The journal of applied ecology, 35(12):3339-3348.

Climate productivity is a key indicator reflecting carbon exchange of plant communities. Clarifying changes in climate productivity is of great significance for assessing the carbon sink function of ecosystems. We used the Miami and Thornthwaite-Memorial models to simulate temperature-, precipitation- and evapotranspiration-producti-vity in the three northeastern provinces based on temperature and precipitation data from 1971 to 2020. We used trend analysis, wavelet analysis, M-K test and regression analysis to explicitly analyze the spatial and temporal variations of climate productivity, and model the changing characteristics of evapotranspiration productivity under future climate change scenarios. We further explored the accuracy of the test for climate productivity in conjunction with data from Pinus sylvestris var. mongolica tree-ring data at 11 sampling sites in the three northeastern provinces. Results showed that the annual averages of temperature productivity (YT), precipitation productivity (YP) and evapotranspiration productivity (YE) in the three northeastern provinces during 1971-2020 were 777.84, 946.08, and 930.4 g·m[-2]·a[-1], respectively. All the three types of climate productivity generally showed increasing trends. The increasing trend of temperature productivity was the most significant, increasing at a rate of 1.91 g·m[-2]·a[-1], existence of 6, 10, 22 years major periodic, and had abrupt change in 1988. There were significant differences in the spatial distribution of climate productivity. Temperature productivity decreased from south to north, with overall increasing trend in climate tendency rates. Precipitation productivity and evapotranspiration productivity decreased from southeast to northwest, which was higher in the east than in the west. Their climate tendency rates showed a decreasing trend in most areas, with an increasing trend occurred in western Heilongjiang and northwestern Jilin. The water-heat ratios of climate productivity in the three northeastern provinces were generally banded with significant spatial variations, with the ratios ranging from 0.58 to 2.42. From north to south, it could be divided into areas that were more affected by precipitation (YP/YT>1.2), water-heat balance (YP/YT≈1), and more affected by temperature (YP/YT<0.8), respectively. The three climate productivities were generally consistent with change in the mean annual tree-ring width index of P. sylvestris var. mongolica at the 11 sampling sites, which was positively correlated, indicating that the modelled climate productivity was reliable. The correlation coefficients between temperature productivity and the width of the annual tree-ring of P. sylvestris var. mongolica decreased significantly with increasing latitude. Our results could improve the understanding of carbon sequestration capacity of vegetation associated with climate productivity in the three northeastern provinces, which would provide a scientific basis for the adaptation of vegetation to climate change and the prediction of future vegetation dynamics.

A framework for assessing uncertainties in drought projections under climate change: Insights from CMIP6 models.

The Science of the total environment, 982:179679 pii:S0048-9697(25)01320-8 [Epub ahead of print].

The impact of climate change on hydrology and drought is commonly assessed using General Circulation Models (GCMs), which introduce considerable uncertainty. This study presents a structured framework to evaluate these uncertainties, focusing on key hydrological parameters and drought characteristics. A multi-criteria statistical approach was used to assess the performance of three selected CMIP6 GCMs- ACCESS-CM2, CanESM5, and ACCESS-ESM1-5- under SSP245 and SSP585 scenarios. Drought conditions were analyzed using the Standardized Precipitation Index (SPI) and the Standardized Precipitation Evapotranspiration Index (SPEI), the latter capturing temperature-driven evapotranspiration. The uncertainty framework integrates a Bayesian probabilistic method for estimating the distribution of drought classifications and a polynomial-based decomposition approach to evaluate the temporal evolution of uncertainty. Applied to six major Iranian watersheds, CanESM5 under SSP585 projected the most extreme outcomes, including a 1.71-fold increase in annual precipitation in the Eastern border watershed and a 0.87-fold decrease in the Persian Gulf watershed. The highest temperature increase, 2.97 °C, was observed in the Caspian Sea watershed. Results indicate a higher probability of normal drought conditions across all watersheds, followed by moderately dry and moderately wet events. Temperature projections showed greater sensitivity to emission scenarios than precipitation, and uncertainties, particularly from GCMs and emission pathways, increased over time. The combined use of Bayesian inference and variance decomposition provides a robust framework for quantifying both the magnitude and sources of uncertainty in drought projections.

Considerations for improving the relevance, use, and robustness of projections of the health risks of climate change.

The Lancet. Planetary health, 9(5):e442-e447.

The increased interest and investment in climate change and health research and policy should be a turning point for providing policy-relevant projections of how changing weather patterns and climate trends could alter the magnitude and distribution of climate-sensitive health outcomes. Decision makers recognise that future health burdens result from interactions between exposure, sensitivity, and the capacity to adapt. Fit-for-purpose projections to inform climate risk management should be based on a range of scenarios of greenhouse gas emissions and socioeconomic development. The relevance, use, and robustness of projections would be improved by addressing the considerations outlined here.

Promoting health through climate change mitigation in Europe.

The Lancet. Planetary health, 9(5):e431-e441.

Several EU climate change mitigation policies have the potential to deliver health co-benefits. However, existing frameworks guiding research in this area lack important details that are needed to understand how evidence of health co-benefits can be used to support the ambition and acceptability of EU climate policy. In this Personal View, we propose an integrated framework for advancing the state-of-the-science on health co-benefits of climate change mitigation and realising the societal effect of evidence documenting co-benefits. We apply this framework to the EU context. Our framework spans multiple economic sectors-including land use, land-use change, and forestry and health systems-and provides details on the different types of mitigation actions, levers of change, and societal actors with the agency to implement specific mitigation actions. This framework aims to inform future research on the magnitude of health co-benefits of climate change mitigation, and provide strategies to communicate health co-benefits to support increases in mitigation ambition and societal acceptance of mitigation actions.

Spatial distribution of soil organic carbon components in mainland of China and their response to climate change.

Ying yong sheng tai xue bao = The journal of applied ecology, 36(3):847-858.

Preserving and increasing soil organic carbon pool is an effective natural way to mitigate climate change. However, the sensitivity of soil organic carbon to climate change in different ecosystems in mainland of China is still unclear. To investigate the response of soil organic carbon to climate change, it is important to classify it into particulate (POC) and mineral-associated organic carbon (MAOC) components. In this study, we assessed the spatial distributions of POC and MAOC in mainland of China and simulated their responses to future climate change using machine learning methods. The results showed that: 1) the stocks of soil organic carbon, POC, and MAOC in the top 20 cm soils of mainland China were 45.3, 20.7, and 24.6 Pg, respectively. 2) Soil organic carbon components were positively correlated with altitude and negatively correlated with air temperature. 3) Under the SSP585 scenario, the stocks of POC and MAOC in China would decrease by 4.80 and 2.13 Pg, from 2020 to 2100, respectively. The contents of soil organic carbon components were higher in Northeast China and Qinghai-Tibet Plateau, but lower in the Inner Mongolia Plateau, Sichuan Basin, North China, and Northwest China Plain. The sensitivity of POC to climate change was higher than MAOC. Climate warming would cause the greatest loss of soil organic carbon in the meadow ecosystem.

Sustainable prospective proposals for utilizing modifiers in bitumen industry to address global warming.

Scientific reports, 15(1):17042.

The rapid rise in greenhouse emissions has intensified climate change, highlighting the urgent need to assess its impact on critical infrastructure. Asphalt pavements, are particularly vulnerable to the stresses caused by climate change including rising temperatures and shifting precipitation patterns. The paper examines the impact of global warming on asphalt pavements using the Prophet model under three scenarios, focusing especially on variations in the performance grade of bitumen obtained from 34 synoptic stations of Iran. This study outlines types and precise of additives needed to meet evolving bitumen requirements through 2060. To promote sustainability in Iran's bitumen industry, this study includes a detailed economic and environmental analysis of additive production, transportation, and blending with existing bitumen sources. Findings suggest in 2060, Iran's bitumen demands can be met by producing PG 82 -16 and PG 76 -28 grades. The results showed that using styrene-butadiene-styrene (SBS) instead of crumb rubber (CR) led to a 46% increase in carbon dioxide emissions and a 1700% increase in costs. In contrast, replacing polyphosphoric acid (PPA) with crumb rubber reduced costs by 56%, while causing a 13% increase in carbon dioxide emissions. This study provides an innovative hybrid framework for temperature prediction under different scenarios using a machine learning model, forecasting bitumen performance grading, and evaluating the environmental impacts of various additives to enhance the performance of existing bitumens.

Modelling the combined impacts of climate change and socio-economic development on waterborne pathogen transport.

Water research, 283:123802 pii:S0043-1354(25)00711-0 [Epub ahead of print].

Protection of our water resources is essential to provide future generations with safe drinking water, recreational opportunities, and reliable ecosystem services. Climate and land use changes exert pressure on the quality of our water resources. Additionally, societal development may generate both positive and negative impacts on future water quality. Thus, decisions made today will impact the water quality of tomorrow. In this paper, we address the issue of future microbial water quality by combining Representative Concentration Pathways and Shared Socio-economic Pathways with projections of societal development, either downscaled to a local level or assessed by local organisations. We use Lake Vomb in Sweden (providing approximately 330 000 persons with drinking water) to illustrate our novel approach of assessing the impact of climate change and societal development on future microbial water quality. The approach includes norovirus, Escherichia coli (as an indicator organism), and Cryptosporidium. Further, we combine hydrological and hydrodynamic fate and transport modelling to simulate future water quality in the tributaries and at the drinking water intake. Future simulations are compared to a baseline scenario representing the current situation. Results show that climate change will reduce future water quality. However, we can also see that societal development significantly impacts microbial water quality, potentially counteracting the increases in microbial concentrations induced by climate change. Therefore, drinking water supply management must adapt to both future climate and societal development.

Climate Change, Cryosphere Retreat, and Human Health.

China CDC weekly, 7(12):379-384.

The cryosphere, encompassing glaciers, ice sheets, permafrost, and snow, plays a critical role in regulating climate and sustaining human wellbeing. However, climate change is driving widespread cryosphere degradation, intensifying geophysical and climate-related hazards that pose escalating risks to the public health and safety. The resulting decline in both the quantity and quality of cryosphere services also has severe consequences, particularly for populations in polar regions, high-altitude mountains, and their downstream areas. Furthermore, teleconnected climate systems can even extend cryosphere change impacts beyond these regions. It has been seen that increasing cryosphere-related hazards, such as glacial lake outburst floods and extreme winter events, heighten public health risks. Disrupted meltwater supply and ecosystem shifts inflict water and food insecurity in arid and semiarid regions, exacerbating malnutrition and disease burdens. Additionally, thawing permafrost may release ancient pathogens and toxic substances, increasing the risks of infectious disease outbreaks and severe environmental contamination. Addressing these cascading risks requires urgent interdisciplinary research, public awareness, and investment in adaptive strategies to strengthen societal resilience amid a rapidly changing cryosphere and safeguard public well-being.

Local Adaptation and Climate Change Vulnerability of the Relict Tree Species Taiwania cryptomerioides Provide Insights Into Its Conservation and Restoration.

Evolutionary applications, 18(5):e70113.

Rapid climate change is affecting biodiversity and threatening locally adapted species. Relict species are often confined to relatively narrow, discontinuous geographic ranges and provide excellent opportunities to study local adaptation and extinction. Understanding the adaptive genetic variation and genetic vulnerability of relict species under climate change is essential for their conservation and management efforts. Here, we applied a landscape genomics approach to investigate the population genetic structure and predict adaptive capacity to climatic change for Taiwania cryptomerioides Hayata, a vulnerable Tertiary relict tree species in China. We used restriction site-associated DNA sequencing on 122 individuals across 10 sampling sites. We found three genetic groups across the Chinese range of T. cryptomerioides: the southwest, central-eastern, and Taiwanese groups. We detected significant signals of isolation by environment and isolation by distance, with environment playing a more important role than geography in shaping spatial genetic variation in T. cryptomerioides. Moreover, some outliers were related to defense and stress responses, which could reflect the genomic basis of adaptation. Gradient forest (GF) analysis revealed that precipitation-related variables were important in driving adaptive variation in T. cryptomerioides. Ecological niche modeling and GF analysis revealed that the central-eastern populations were more vulnerable to future climate change than other populations, with range contractions and high genetic offsets, suggesting these populations may be at higher risk of decline or local extinction. These findings deepen our understanding of local adaptation and vulnerability to climate change in relict tree species and will guide conservation and restoration programs for T. cryptomerioides in the future.

Contribution of climate change and human activity to vegetation recovery in Shanxi Province from 2002 to 2022.

Ying yong sheng tai xue bao = The journal of applied ecology, 36(1):219-226.

Shanxi Province has fully implemented ecological protection and restoration initiatives since 2002. Assessing the spatiotemporal variations in vegetation across Shanxi is crucial for timely adjustments to ecological construction measures and ensuring their effectiveness. Based on normalized difference vegetation index (NDVI), temperature, and precipitation data from 2002 to 2022, we employed the pixel dichotomy method, trend analysis, and multiple regression residual analysis to simulate the spatiotemporal variations of vegetation cover in all the 11 muni-cipal regions of Shanxi Province. By comparing potential NDVI with actual NDVI, we assessed the relative contributions of climate change and human activity to vegetation restoration. The results showed that vegetation coverage in different cities of Shanxi Province was mainly medium-high and high cover from 2002 to 2022, with Jincheng sho-wing the highest coverage and Shuozhou showing the lowest. Climate change and human activity together promoted rapid NDVI growth during the growing season in Shanxi Province, with a growth rate of 5.4×10[-3]·a[-1]. The areas with significant NDVI increase accounted for 72.1% of the total area. Within the municipalities, Lyuliang demonstrated the fastest NDVI growth rate (7.3×10[-3]·a[-1]). Human activity played a significant role in promoting vegetation restoration in Shanxi Province, while climate change had moderate contribution, with relative contribution rates of 76.3% and 23.7%, respectively. In Changzhi, Jincheng, and Yuncheng, the relative contribution rates of human activity exceeded 90%. Climate change notably facilitated vegetation restoration in Lyuliang. NDVI decreased signi-ficantly at the junction of Taiyuan, Lyuliang, and Jinzhong and in several city centers, slightly suppressed by climate change and moderately suppressed by human activity. The NDVI in Shanxi Province was significantly positive, and overall vegetation cover had reached a relatively high level. But, vegetation cover remained low in northern Shanxi. The relative contribution of human activity was highest in the southern region, while climate change had higher contribution in the central-western region.

Predicting the future impact of climate change on the distribution of species in Egypt's mediterranean ecosystems.

BMC plant biology, 25(1):644.

As climate change accelerates, it may significantly alter species distributions and endanger many species. The use of species distribution modeling (SDM) has become increasingly vital for assessing the likely effects of climatic changes on biodiversity. This approach is especially relevant as our understanding of environmental shifts and their ecological implications deepens. SDMs are frequently employed to forecast future shifts in species' geographic ranges, estimate extinction risks, evaluate the effectiveness of existing conservation areas, and prioritize conservation efforts. The urgency of these assessments is highlighted by the fact that the Mediterranean area is heating up 20% quicker than the universal average. Given that species have varying ecological tolerances and attributes, their biological responses to environmental changes are likely to differ significantly. This study aimed to assess the potential future distribution of three native Mediterranean species- Thymelaea hirsuta (L.) Endl., Ononis vaginalis Vahl, and Limoniastrum monopetalum (L.) Boiss.-under two GCMs of HadGEM3-GC31-LL and IPSL-CM6A-LR for the periods of 2060s and 2080s and two Shared Socioeconomic Pathway (SSP 1-2.6 and SSP5-8.5), comparing the use of MaxEnt and ensemble modelling techniques in predicting the impact of future climatic changes on these species' distribution. The results indicated that there are high similarities and agreement between MaxEnt and the ensemble models' outputs. The two modelling techniques exhibited excellent fits and performance. The distribution range of T. hirsuta and O. vaginalis will expand and migrate to the northwest direction of the Mediterranean coast of Egypt, while L. monopetalum will contract. The insights gained from species distribution modeling could guide future conservation efforts and promote the sustainable use of the studied species in the arid coastal environments of the Mediterranean region.

Quantifying the impact of future climate change on the risk of coral rubble instability across the Great Barrier Reef by 2100.

Journal of environmental management, 386:125716 pii:S0301-4797(25)01692-5 [Epub ahead of print].

Coral reef systems are facing unprecedented pressures due to climate change, and stable coral rubble substrates are crucial for facilitating large-scale coral regeneration. This study integrates the Sixth Phase of the Coupled Model Intercomparison Project climate models, sea-level rise projections from the Intergovernmental Panel on Climate Change Sixth Assessment Report, Shared Socioeconomic Pathway scenarios, and applies machine learning techniques to assess the risk of coral rubble instability in the Great Barrier Reef under future wave climate and depth change scenarios. Using the EC-Earth climate model under the SSP5-8.5 scenario-calibrated with data from 41 synoptic stations-we estimated various climate data for 2031-2100 and examined the impact of key factors such as wave climate and depth changes on the risk of coral instability. Coral rubble instability risk depends on future wave climate and depth changes from sea-level rise and deposition. Future changes in wave climate are expected to increase the risk of instability, while increased depth mitigates these destabilizing effects. Over the next 70 years, most areas of the Great Barrier Reef are projected to experience stable or decreasing risk of coral rubble instability. The proportion of no-risk areas is higher in the northern regions, whereas the far southern regions have fewer no-risk areas and more high-risk zones. High-risk and very high-risk areas are mainly concentrated along reef edges, reefs facing the Pacific Ocean, and shallow waters near the shoreline. The transition between high-risk and low-risk areas is gradual rather than abrupt. Annual projections align with long-term trends: coral rubble remains relatively stable in the northern and central regions, which is more conducive to future coral recovery. However, the persistent presence of high-risk and very high risk areas poses significant challenges to coral recovery in the far southern region. By providing insights into the spatial and temporal evolution of coral rubble instability risk, this study aims to support decision-makers, environmental scientists and researchers in formulating appropriate interventions to enhance the resilience of coral reefs under changing environmental conditions.

Quantifying role of source variations on PM2.5-bound toxic components under climate change: Measurement at multiple sites during 2018-2022 in a Chinese megacity.

Journal of hazardous materials, 494:138584 pii:S0304-3894(25)01500-6 [Epub ahead of print].

Understanding the response of PM2.5-bound toxic components to source variations under climate change is crucial for public health protection. However, the lack of long-term and multi-site observational data of toxic components limits such efforts. Here, we conducted a five-year PM2.5 measurement (2018-2022) at 10 sites across a Chinese megacity, analyzing 15 polycyclic aromatic hydrocarbons (PAHs), 6 organophosphate esters (OPEs), and 9 potentially toxic elements (PTEs). Using explainable machine learning, we found that source variations from particle matter mass reduction under climate change can impact PM2.5-bound toxic components. Meteorological factors like extreme heat days and max temperature impact most toxic components, while geographic, socioeconomic, and anthropogenic factors mainly affect PTEs, especially Cu. We also designed 10 extreme heat and source variation scenarios to predict the response of toxic components. When comparing scenario 2-1 (source variation without temperature change) with scenario 2-2 and 2-3 (the same source variation but higher temperatures), many PM2.5-bound organics and As show higher reduction rates under climate change, highlighting the need to focus more on gas-phase organics and products of atmospheric process. Benzo[b]fluoranthene (BbF) is most sensitive to traffic source reductions, and Cu, Mn, Zn and Fe are more sensitive to industrial source reductions.

Sustainability insights from Late Pleistocene climate change and horse migration patterns.

Science (New York, N.Y.), 388(6748):748-755.

Climate affects habitat, food availability, and the movement and sustainability of all life. In this work, we apply Indigenous and Western scientific methods, including genomics and isotope profiling, on fossils from across Beringia to explore the effect of climate change on horses. We find that Late Pleistocene horses from Alaska and northern Yukon are related to populations from Eurasia and crossed the Bering land bridge multiple times during the last glacial interval. We also find deeply divergent lineages north and south of the American ice sheets that genetically influenced populations across Beringia and into Eurasia. As climate warmed and horses entered the ice-free corridor connecting Beringia and midcontinental America, restricted mobility and food availability impeded population growth. Our combined Western and Indigenous framework offers critical guidance for wildlife conservation amid ongoing climate change.

Public health nursing (Boston, Mass.) [Epub ahead of print].

AIM: The primary aim of the study was to explore the impact of women's climate change awareness on fertility desire, while the secondary aim was to explore the factors influencing women's fertility desire.

MATERIAL AND METHODS: The study was performed descriptive and correlational type with 440 women without children between March and October 2023. The women's characteristics form and Fertility Desire Scale and Climate Change Awareness Scale were used for data collection.

RESULTS: The mean age of the women was 26.2 ± 4 years, with 55.2% aged 26 or younger; 54.3% held university degrees, and 93% had health insurance. Findings indicate a significant mean total score of 50.7 ± 7.6 on the Fertility Desire Scale, influenced by education, health insurance, income level, marital duration, and type of marriage. Women with higher education levels and those in couple-initiated marriages reported lower fertility desire. The Climate Change Awareness Scale showed a mean score of 210.8 ± 23.2, with higher awareness among those over 26, employed, and with higher education. Multiple linear regression analysis revealed significant predictors of fertility desire, including marital duration and income level. Notably, climate change awareness negatively correlated with fertility desire, explaining 3.1% of the variance.

CONCLUSIONS: These findings highlight the complex interplay between environmental concerns and reproductive intentions among women, indicating a need for further research in this area.

Ying yong sheng tai xue bao = The journal of applied ecology, 36(4):1251-1260.

Under the context of global climate change, the shifts in suitable habitats of different species have become one of the major threats to biodiversity. We simulated the distribution habitats of Grus nigricollis under current climatic condition and predicted potential changes under three climate scenarios (SSP126, SSP245, and SSP585) with the MaxEnt model based on the distribution records of G. nigricollis and environmental variables. The results showed that: 1) Elevation, annual temperature range, and mean temperature of the wettest quarter were the main environmental factors affecting the distribution of potential breeding habitats for G. nigricollis, while the wintering habitats were significantly influenced by factors such as isothermality, elevation, and temperature annual range. 2) Under the current climate condition, the breeding habitats of G. nigricollis were mainly distributed in Xinjiang, Gansu, Qinghai, Tibet, Sichuan of China, as well as India, with a highly suitable breeding area of 27.07×10[4] km[2]. The wintering grounds were primarily located in Tibet, Sichuan, Yunnan of China, as well as Bhutan, Nepal, India, and Myanmar, with a highly suitable wintering area of 21.15×10[4] km[2]. 3) Under future climate scenarios, the overall potential suitable habitats for G. nigricollis remained stable, with the retention rate of stable areas exceeding 80%. Among these, the breeding habitats showed an increasing trend, while the wintering habitats exhibited a decreasing trend. 4) Under different climate scenarios, the centroid of breeding ground of G. nigricollis would gene-rally move southeastward, while the centroid of wintering ground mainly moved westward, potentially reducing migration distance. By predicting the changes in the potential suitable habitat for G. nigricollis on a large regional scale under future climate scenarios and revealing the impact of climate change on their distribution, this study could provide a scientific basis for the conservation of G. nigricollis and the formulation of relevant strategies.

An assessment of ocean thermal energy conversion resources and climate change mitigation potential.

Climatic change, 178(5):103.

Ocean thermal energy conversion (OTEC) is a renewable energy system that harnesses the thermal gradient between surface and deep waters. Many multi-century simulations with a fully coupled climate-carbon cycle model are presented to explore the amount of extractable energy and the climate change mitigation potential from the widespread implementation of OTEC. The sustainability of OTEC power generation was assessed for present and possible future climate states. A warmer climate reduced the sustainable power potential of OTEC. OTEC could briefly produce over 35 TW of power and, depending on the climate state, maximum power production rates of 5 to 10 TW were found to be sustainable on multi-millennial timescales. Over 500 years of simulation, with a high emission scenario (equivalent to RCP8.5), the power from OTEC deployments, with peak power generation ranging from 3 to 15 TW at the year 2100, resulted in cumulative emission reductions equivalent to 36% to 111% of historical carbon emissions from 1750 to 2023 relative to the scenario without OTEC. Such significant emissions reductions coupled with sustained OTEC-induced mixing led to globally averaged atmosphere temperature decreases of up to 2.5 ºC by the year 2100 and up to 4 ºC by the year 2500 compared to a scenario without OTEC. While caution is required, and the engineering challenges would be large, early indications suggest that the large-scale implementation of OTEC could make a substantial contribution to climate change mitigation.

A Global Review of the Impacts of Climate Change and Variability on Agricultural Productivity and Farmers' Adaptation Strategies.

Food science & nutrition, 13(5):e70260.

Climate change and variability-marked by rising temperatures, altered precipitation, and increased extreme weather-have significant impacts on agriculture, especially in Ethiopia, where farming is the primary livelihood source. In Sub-Saharan Africa, staple crop yields are projected to decline by 10%-20% by 2050 under current climate trends, threatening food security and rural economies. In Ethiopia, maize yields may decrease by around 15% by 2050 due to temperature increases and erratic rainfall. These challenges are not unique to Ethiopia; other climate-sensitive regions like South Asia and Latin America face similar risks. For instance, rice and wheat production in South Asia could decline by 10%-15% by mid-century due to heat stress and changing monsoon patterns, affecting millions of smallholder farmers. This review systematically examined literature from 2000 to 2024, focusing on climate change impacts and adaptation strategies in Ethiopia and comparable regions. The increasing frequency of droughts and heatwaves in East Africa has worsened crop failures, with wheat yields declining by up to 25% in certain areas over recent decades. Climate variability-characterized by rising temperatures and unpredictable rainfall-disrupts growing seasons and reduces yields, exacerbating food insecurity. In Ethiopia, climate-induced reductions in crop output have led to an estimated 5%-10% decline in annual agricultural GDP. The heavy reliance on rain-fed agriculture, combined with limited adaptive capacity and socio-economic vulnerability, intensifies these impacts, resulting in food shortages and economic strain. Beyond Africa, regions dependent on monsoon systems, particularly in South Asia, are also experiencing declining crop productivity. Projected climate scenarios suggest that by 2080, crop production in drought-prone areas across Africa and South Asia could decrease by up to 25% due to rising temperatures and altered rainfall.

Climate Change-Driven Heatwaves Pose Lethal Risks to Newborn Forest Bats.

Ecology and evolution, 15(5):e71350.

Climate change poses a significant threat to biodiversity, with extreme weather events such as heatwaves exacerbating the risks to animal populations. Temperature extremes can cause high physiological stress in animals, particularly in species or life stages with limited thermoregulatory abilities. While available evidence pertains to flying foxes and bats using bat boxes or dwelling in urban environments, heatwave-induced mortality in forest-dwelling species in temperate forests has not been reported. We present the first evidence of heatwave-related mortality in temperate forest bats, specifically in common noctules Nyctalus noctula, observed in northeast Italy during the summers of 2023 and 2024. Our fieldwork, conducted in a forest fragment in the Friuli-Venezia Giulia Region (Northeastern Italy), identified 17 dead juvenile bats found at the base of roost trees during periods of extreme heat (Tmax ≥ 30°C). Laboratory necropsies revealed that the cause of death was consistent with heat-related stress, as no viral infections were detected, and recent feeding evidence was present in a few individuals. Dead bats are difficult to find in forests, especially when mortality occurs in unsurveyed areas, scavengers remove carcasses, or deaths go unnoticed within roost cavities. Consequently, our observations likely represent only a limited fraction of actual mortality. The phenomenon may be quantitatively significant and widespread. The findings highlight the vulnerability of bat populations to heatwaves, particularly in fragmented forest habitats where roosting opportunities are limited. Our results allow us to hypothesise that forest fragmentation increases exposure to heat stress, particularly along forest edges. In the context of climate change, roosts deemed suitable may act as ecological traps, making this a hypothesis worth testing.

Spatial and temporal variations in ecosystem health and coping strategy in the Hexi Corridor under climate change.

Ying yong sheng tai xue bao = The journal of applied ecology, 36(2):537-546.

The health status of ecosystems is the foundation for global climate change adaptation decision-making and a fundamental prerequisite for ensuring regional ecosystem stability. We constructed an ecosystem health assessment indicator system based on a contribution, vigor, organization and resilience model from the perspectives of system integrity and contributive capacity. With this system, we analyzed the spatial-temporal variation of ecosystem health in Hexi Corridor and its relationship with climate change from 2000 to 2020 by utilizing the bivariate Moran's index. Results showed that the ecosystem health index in the Hexi Corridor improved by 2.5% during 2000-2020. The central oasis area and the southeastern mountainous area showed significant improvement in ecological health, while the northern desert area and some localized regions experienced degradation. During the study period, the overall health status of the Hexi Corridor's ecosystem remained at a moderate level, with consistent trend across various dimensions that initially declined before subsequently rising. There was a significant spatial positive correlation between climate change and ecosystem health. In the arid and low-precipitation condition of the Hexi Corridor, increased average annual precipitation and elevated average annual temperature contributed positively to ecosystem health, which was the key determinants of regional ecosystem health. Finally, we proposed corresponding strategies for enhancing ecosystem health levels in the southern Qilian Mountain area, the central oasis areas, and the nor-thern desert areas.

Climate change as a game changer: Rethinking Africa's food security- health outcome nexus through a multi-sectoral lens.

Scientific reports, 15(1):16824.

In Africa, the intricate relationship between food security and health outcomes is increasingly challenged by the unpredictable forces of climate change. With this in mind, we utilized panel data spanning from 2010-2022 for 46 African nations, sub-grouped into regional panels to analyze the moderating role of climate change on food security- health outcome nexus, contributing to Sustainable Development Goals (SDGs) 2 (Zero Hunger), 3 (Good Health and Well-Being), and 13 (Climate Action). Considering issues of residual cross-sectional dependence and slope heterogeneity which are potential in panel data setting, the study utilized the Augmented Mean Group and the Common Correlated Mean Group techniques as the main methods in estimating the relationships amid the employed variables. Major outcomes from the study's analysis revealed that, across all panels of African states, there is no doubt that climate change has a substantial, direct detrimental impact on health outcomes. Also, while the moderating effect of climate change is clearly negative in the case of Northern and Central regional panels, it is significantly positive in the aggregated, Eastern, Western, and Southern African regions with regard to the relationship between food security and health outcomes. In light of these findings, addressing the relationship between food security and health in Africa while taking the moderating impacts of climate change into account requires a region-specific approach.

Confronting the uncertainty: Vulnerability to climate change among smallholder farmers in the Sidaama region, Ethiopia.

PloS one, 20(5):e0323469.

Smallholder farmers' vulnerability to climate change varies due to socio-economic and biophysical factors, requiring a context-specific assessment. This study examines livelihood vulnerability in the face of climate change in the Sidaama Region, Ethiopia. A mixed-methods approach with a descriptive and explanatory sequential design was employed. Data from 391 systematically sampled households were analyzed using the Livelihood Vulnerability Index (LVI) and the Intergovernmental Panel on Climate Change (IPCC) framework (LVI_IPCC), alongside Kruskal-Wallis and Dunn's tests. Results of LVI analysis indicate that the Lowland agroecological zone (AEZ) is the most vulnerable (0.466), followed by the Highland (0.412), while the Midland is least vulnerable (0.376). The Highland AEZ showed greater sensitivity to climate change, whereas the Lowland had the weakest adaptive capacity. The Kruskal-Wallis H test confirmed significant differences in vulnerability across AEZs (H = 49.083, p < 0.001), with Dunn's test revealing that the Lowland AEZ is significantly more vulnerable than both the Highland and Midland. LVI_IPCC results similarly ranked the Lowland as the most vulnerable (-0.0041), followed by the Midland (-0.072), with the Highland being the least vulnerable (-0.096). Boxplot analysis further confirmed that the lowland had the highest median LVI_IPCC, indicating greater livelihood vulnerability, while the Highland and Midland had lower median values. To reduce vulnerability, targeted interventions such as climate-smart agriculture, diversified income sources, improved microfinance access, and tailored climate adaptation strategies are needed. Local, regional, and national governments should prioritize disaster prevention and mitigation in the Lowland while leveraging the Midland's higher adaptability for piloting innovative adaptation strategies.

A protozoan perspective on climate change and biosafety threats: differences in testate amoebae in lakes in forest-swamp and forest-steppe zones in Western Siberia.

Applied and environmental microbiology [Epub ahead of print].

The problem of increasing salinity and mineralization in natural and artificial freshwater bodies with climate warming is very relevant nowadays, as it leads to changes in the species composition of planktonic organisms. Testate amoebae are one of the responsive bioindicators that are sensitive to even minor changes in environmental conditions. In this study, a comparative analysis of the species diversity of planktonic testate amoebae was carried out in a number of lakes in the forest-steppe and forest-swamp natural zones of Western Siberia using microscopy and metabarcoding. One new species, Pseudodifflugia siemensmai sp. nov., was described. The detection frequency and the number of reads of amplicon sequence variants of potentially pathogenic testate amoebae belonging to the genera Rhogostoma and Fisculla were higher in forest-steppe lakes. Universal eukaryotic primers for the 18S rRNA gene are well suited for identifying testate amoebae from the supergroup Cercozoa but are practically not applicable for identifying Amoebozoa testaceans. The plankton of the lakes with the highest mineralization and salinity was characterized by the most specific species composition. These results should be taken into account when predicting changes in aquatic communities with further climate warming, which may also be associated with an increase in the occurrence of pathogenic testaceans that pose biosafety threats.IMPORTANCEMicroscopic and metabarcoding analyses reveal important differences in testate amoebae communities in lakes in two natural and climatic zones of Western Siberia that should be taken into account when predicting changes in aquatic communities with further climate warming, which may also be associated with an increase in the occurrence of pathogenic testaceans that pose biosafety threats.

The relationship between future anxiety and awareness of global climate change in nursing students.

The International journal of social psychiatry [Epub ahead of print].

AIM: The aim of this study is to determine the relationship between nursing students' future anxiety and awareness of global climate change.

METHOD: The population of this correlational descriptive study consisted of nursing students studying at a nursing faculty. Three hundred and thirty nursing students were included in the study. The researcher collected data through google forms using a Descriptive Characteristics Form, the Awareness Scale of University Students About Global Climate Change (ASUSGCC) and the Future Anxiety Scale in University Students (FASUS) between March and May 2024.

RESULTS: The ASUSGCC total mean score of the nursing students was 3.43 ± 0.88. Their FASUS total mean score was 61.39 ± 12.98. There was a statistically significant positive, weak correlation between their ASUSGCC and FASUS total mean scores (p < .05).

CONCLUSION: It was found that the nursing students had a moderate level of awareness about global climate change. It can be asserted that the participants had a moderate level of future anxiety based on their FASUS total mean score. In the study, as their level of awareness about climate change elevated, did so their level of future anxiety.

Rodent Seed Dispersal Syndromes Follow a Downslope Trajectory, Counteracting the Climate Change-Mediated Tree Line Elevational Shift Upwards.

Ecology and evolution, 15(5):e71388.

Forest rodents are important mediators of plant seed dispersal and their seed caching tactics are influenced by a variety of environmental factors; however, the role of terrain slope remains uninvestigated. We examined how the dispersal of Castanea mollissima seeds by an assemblage of scatter-hoarding rodents in the Qinling Mountains, China, was affected by slope direction and gradient in relation to seed fate. In this study, the topographic factor, which has been frequently overlooked in previous ecological studies, was investigated. It was revealed that the sloping terrain could affect the dispersal behavior of rodents toward plant seeds and ultimately influence the direction of plant dispersal. This finding brings new insights to ecological research. Overall, rodents were 1.55 more likely to transport seed downhill than uphill, and downhill mean translocation distance was 1.41 times greater than uphill, suggesting an overarching tendency for energy conservation. When comparing steep (> 35°) with shallow (< 35°) slopes, this gradient effect was strongest on gentle slopes, with other factors likely exerting a greater influence on steeper terrain. We discuss these findings both from the perspective of rodent optimal foraging in 'landscapes of fear' and heterogeneous 'energy landscapes', as well as in the context of the counteractive pressure for trees to achieve an uphill elevational shift in response to global warming.

Exploring barriers and facilitators to integrating health equity into health and climate change policies in Nepal - a qualitative study among federal level stakeholders.

BMC health services research, 25(1):687.

BACKGROUND: Health is foundational for climate action, and integrating climate and health policies to achieve health equity is widely recognized. While there is a growing global momentum for collaborative health and climate initiatives, more effort is needed to incorporate health equity into national climate policies. Achieving this necessitates identifying both barriers and facilitators of integrated policymaking. This study examines the barriers and facilitators to integrating health equity into climate change-related policies at Nepal's federal level.

METHODS: We interviewed 14 key stakeholders from three major federal ministries, a high-level government entity, and a government partner institution in Nepal, all with diverse roles and responsibilities. To facilitate discussions, we developed an interview guide informed by two policy analysis frameworks: Health Equity Policy Process Analysis Framework and Schlossberg's Framework of Environmental Justice. Using both inductive and deductive approaches, we identified five key facilitators and four major barriers to integrating health equity in climate change-related policies in Nepal. We present these barriers in relation to WHO's climate-resilient health systems framework.

RESULTS: A wide array of facilitators was identified, broadly categorized as a) acknowledgement of the need to integrate health equity in climate change policies, b) political leadership, c) global influences, d) established mechanisms and structures in place for collaboration and e) the federal structure. Barriers identified were largely systemic and encompassed a) knowledge gaps, b) ownership and accountability, c) resource constraints: human resources and budget and d) data limitations. Among these, the issue of ownership and accountability emerged as an overarching theme, cutting across all barriers. Similarly, financing and knowledge gaps were identified as significant obstacles to progress.

CONCLUSIONS: The findings underscore the need for a more structured approach, with clearly delineated responsibilities to ensure all relevant sectors contribute to the goal of health equity in climate action. Developing well-defined guidelines outlining the roles and responsibilities of different sectors involved in climate action is crucial for fostering ownership and ensuring that health equity is effectively integrated into climate change policies, as well as aiding in resource allocation. We recommend future research to explore the potential role of policy champions within ministries in advocating for and advancing health equity within climate change-related policies.

Responses of grassland soil mesofauna to induced climate change.

Scientific reports, 15(1):16532.

Climate change can significantly affect the below and above-ground ecosystems. This study aimed to test the effects of induced climate change on the composition of soil mesofauna and vascular plant species in semi-natural grasslands. Open-top chambers (OTCs) were used to manipulate climatic conditions. The research was carried out over three years in two semi-natural grasslands in south-west Poland (Central Europe). Changes in soil mesofauna (Collembola and Acari) and vegetation characteristics under OTC treatment were evaluated and compared to untreated control sites. Treatment with OTC significantly increased the abundance of Oribatida mites (up to 42%) but decreased the abundance of Gamasida (by 21%), indicating contrasting responses of the Acari subgroups to warming. Collembola diversity was significantly reduced under OTC conditions, as reflected in the lower Margalef, Simpson, and Shannon-Wiener indices. Furthermore, the abundance of epigeic Collembola increased under OTC. Redundancy analysis (RDA) revealed that plant traits explained 37.91% of the variation in mesofauna structure. Structural Equation Modelling (SEM) further supported these findings, showing that climate exerted a strong negative effect on soil quality, which in turn had a pronounced positive influence on plant quality (total effect = 0.678). Plant quality significantly enhanced soil fauna abundance (total effect = 0.264), while the overall impact of climate on soil fauna was negative (- 0.231), primarily via indirect pathways. These findings suggest that climate change in grassland ecosystems can disrupt the ecological balance of soil fauna by modifying their responses to environmental variables. The SEM results emphasise the cascading nature of these effects, from climate to soil, vegetation, and ultimately soil fauna, highlighting the importance of indirect environmental pressures. Conserving plant diversity remains essential to buffer against climate-driven disruptions and maintain ecosystem stability.

Climate change impacts the symptomology and healthcare of multiple sclerosis patients through fatigue and heat sensitivity - A systematic review.

Journal of the neurological sciences, 474:123526 pii:S0022-510X(25)00143-1 [Epub ahead of print].

BACKGROUND: Climate change, in terms of global warming and heat waves, might negatively impact people with neurological diseases. Patients with Multiple Sclerosis (MS), which is characterized by heat sensitivity, may therefore have an increased vulnerability. Subsequently, we aimed to specifically investigate the state of knowledge on climate change and MS.

METHODS: We conducted a literature search in the Pub Med database during 2022-2024 using the search terms "multiple sclerosis" AND "climate ", "climate change", "global warming", "heat waves", and "seasonal variations". A total of 773 scientifical papers were retrieved and scrutinized according to the inclusion/exclusion criteria. Finally, 24 publications were manually selected based on their relevance to the intended topic, covering climate change related heat sensitivity in MS patients, associated healthcare burden, and treatment strategies.

RESULTS: Only few publications focused on climate change and its effect on MS. The search yielded 24 articles on effects of climate/environmental heat and seasonal variations on MS. There was both evidence of worsened clinical symptoms as well as negative studies. However, the majority of selected papers, 16/24 (67 %) revealed an impact on MS symptoms/hospitalization from environmental heat.

CONCLUSIONS: So far there has been limited interest in the vulnerability of MS patients to climate change. The future perspective of increased temperature and heat waves should be highlighted so that authorities prepare health systems to apply to this new, but logical and intuitive, scientific knowledge. As heat sensitivity also seems to affect neurological disorders beyond MS, further research is needed to develop general care strategies in the future.

Projections of heat-related mortality in Chinese cities: The roles of climate change, urbanization, socioeconomic adaptation, and landscape level strategies.

Environmental health perspectives [Epub ahead of print].

BACKGROUND: Physiological heat strain induced by extreme temperature in cities has led to significant heat-related deaths. Although socioeconomic adaptation is suggested to mitigate this issue, its effectiveness is limited. Conversely, there is a lack of comprehensive evaluation on the effectiveness of landscape level strategies for mitigating heat-related deaths.

OBJECTIVES: We developed a comprehensive modeling framework to estimate the impacts of environmental stresses and mitigating strategies on heat-related deaths in China's cities from 2016 to 2055.

METHODS: The framework assesses future heat-related deaths through five experiments considering the influences of climate change, urbanization, socioeconomic adaptation, and landscape level strategies. We used extrapolated region-specific exposure-response functions (ERF) and recent advancement of geo-statistics for public health to generate urban patch level ERF curves. We used these curves, temperature and population data to generate future heat-related deaths with 1 km resolution and conducted 5,000 Monte Carlo simulations for uncertainty analysis.

RESULTS: Our analyses estimated that heat-related mortality will increase from 136.5±16.5 deaths per million in 2016 to 175.7±27.5 deaths per million in 2055 under SSP2-RCP4.5 (shared socioeconomic pathways-representative concentration pathways) scenario and from 140.0±21.4 deaths per million to 230.2±38.7 deaths per million under SSP5-RCP8.5 scenario, despite socioeconomic adaptation and landscape level strategies. Socioeconomic adaptation (reducing deaths by 18.4-64.1 per million) and landscape level strategies (reducing deaths by 45.6-51.3 per million) significantly mitigate heat-related deaths with varying effectiveness across different income levels. Specifically, in high-income cities with dense populations, landscape level strategies are 2.2-4.3 times more effective than socioeconomic adaptation. Within these cities, implementing the same landscape level strategies in the high-density urban centers lead to an additional reduction up to 4.9-6.8 death•km[-2] compared to surrounding areas.

DISCUSSION: Our framework helps to systematically understand the effectiveness of landscape level strategies in reducing heat-related mortality. Future sustainable city management should prioritize landscape level strategies along with socioeconomic adaptation to support healthy and comfortable communities. https://doi.org/10.1289/EHP15010.

Behavioral interventions motivate action to address climate change.

Proceedings of the National Academy of Sciences of the United States of America, 122(20):e2426768122.

Mitigating climate change requires urgent action at individual, collective, and institutional levels. However, individuals may fail to act because they perceive climate change as a threat that is distant or not personally relevant, or believe their actions are not impactful. To address these psychological barriers, we conducted a large-scale "intervention tournament." In a sample of 7,624 participants, we systematically tested 17 interventions that targeted psychological mechanisms described by three key themes: Relevance, Future Thinking, and Response Efficacy. Interventions that emphasized social relevance were the most effective for motivating people to share news articles and petitions about climate change. Interventions that targeted future thinking were the most effective for broadly motivating individual actions (e.g., driving less, eating vegetarian meals) and collective actions (e.g., donating, volunteering) to address climate change. Interventions that emphasized the environmental impact of these actions reliably increased the perceived impact of pro-environmental actions, but did not consistently motivate action. Notably, interventions that targeted two or more mechanisms-such as imagining a future scenario that involved oneself or close others-were most effective. Importantly, our leading interventions were substantially more effective than prevalent existing strategies (e.g., carbon footprint information). Our findings are relevant to theories of behavior change, motivation, and information sharing, with potential applications across domains. Insights from our tournament could be applied to develop scalable online interventions and mass communication campaigns to address climate change.

Mapping Research Priorities for Climate Change Adaptation in Agriculture: A One Health Perspective.

Workplace health & safety [Epub ahead of print].

BACKGROUND: The climate emergency poses significant threats to agricultural productivity, the health and economic prospects of agricultural workers, and animal welfare. This requires development and implementation of adaptation strategies to mitigate the impact in the long-term. The purpose of this study was to identify and map research priorities for climate change adaptation in agriculture, focusing on protecting the health of agricultural workers and livestock animals.

METHODS: Based on the One Health framework, we utilized a participatory, mixed-method approach called group concept mapping. In 2023, 20 faculty members from various disciplines at a land-grant university were recruited through email and purposive sampling, based on group concept mapping methodology. Fifteen faculty members brainstormed ways to reduce health risks for agricultural workers and livestock in the Pacific Northwest amid climate change. Forty ideas were sorted and rated for importance and feasibility by 11 and 10 faculty, respectively.

FINDINGS: Multidimensional scaling yielded five clusters: wildfire smoke impacts, basic science, forecasting extreme weather, tradeoffs, and occupational health and labor. Key research areas include studying wildfire smoke's effects on agricultural products, animals, and workers, and identifying adaptive strategies for climate change's impact on humans and livestock. Overall, 25% included all three pillars of the One Health framework.

CONCLUSIONS: Most research directions were focused on risk management, with limited emphasis on the One Health framework.

APPLICATION TO PRACTICE: Transdisciplinary collaboration is needed to apply a One Health approach in climate adaptation efforts for agriculture and can be enhanced through transdisciplinary education and training opportunities.

Mitigating climate change impacts on health: a comparative analysis of strategies in Saudi Arabia and Lebanon.

Frontiers in public health, 13:1551559.

INTRODUCTION: Human activities are now adding rapidly more greenhouse gases to the atmosphere causing global warming which is one aspect of climate change, the greatest threat to public health. Therefore, this study aims to compare the health impacts of climate change on Saudi Arabia and Lebanon, and assessing their adaptation strategies in addressing climate change challenges.

METHODOLOGY: This study is a descriptive Comparative Analysis, this was performed by analyzing the available data on climate-related health outcomes: food insecurity, emergence of infectious disease and car accidents and by comparing trends and percentages between the two countries.

RESULTS AND DISCUSSION: Saudi Arabia and Lebanon has markable high CO2 emission, which negatively affect the health of people such as Food insecurity (in KSA: The estimated loss over the periods in all the crops ranges from 7 to 25%, in Lebanon: There is a decreased the growth of coveted crops, and increased the growth of weeds and pests), Road traffic accidents (approximately 1.3 million people die as a result of road traffic accidents and 20-50 million people suffer from other injuries.), and Emergence of infectious diseases (in KSA: an increase in 1°C of temperature caused a significant increase (15-25%) in malaria incidence, and increase in risk of food- borne diseases, in Lebanon: There is a vulnerability to the rise in food-borne and vector-borne diseases.). Forecasting the future for both countries reveal to a definite climate change occurring. Further actions could be implemented to overcome the negative health outcomes according to each country. Agriculture and Food Security, Use of renewable energy, and Awareness Campaigns on climate change and health are measures that could be implemented to face the outcomes of climate change. Interestingly, there are some organizations funding initiatives and activities in raising awareness of climate change.

CONCLUSION: Numerous sectors are impacted by climate change, which is a serious issue that requires immediate action. It has a substantial influence on many different sectors and leads to food instability, agricultural issues, an increase in infectious disease transmission, and a rise in traffic accidents. These elements require particular care, and appropriate action should be done to eliminate them.

Mechanisms of global climate change during the five major mass extinctions.

Scientific reports, 15(1):16498.

Since the emergence of diverse animal phyla around 500 million years ago, five major mass extinction events have occurred, each coinciding with abnormal climate changes. We analyzed sedimentary organic molecules from the first and least understood extinction event at the end of the Ordovician period. We divided all five major extinctions into two phases each, totaling ten events, and examined the relationship between climate shifts and the "coronene index"-an indicator of heating temperatures in sedimentary rocks caused by volcanic activity or meteorite impacts. As a result, we found that four of the five extinctions began with global cooling and ended with warming, while one started with an unknown anomaly and also ended with warming. During the initial extinction phases, two events showed low-temperature heating, two high-temperature, and one moderate-temperature. All subsequent warming phases showed moderate-temperature heating. These findings suggest that large-scale volcanic eruptions and meteorite impacts heated sulfides, sulfates, and hydrocarbons at varying temperatures, releasing SO2 or soot into the stratosphere, blocking sunlight, and triggering global cooling and extinction. This was followed by moderate heating of hydrocarbons and carbonates, increasing CO2 emissions and driving long-term global warming, leading to secondary extinction events.

Biomineralization mechanisms in the estuarine oyster (Crassostrea ariakensis): Unveiling the adaptive potential of mollusks in response to rapid climate change.

Environmental pollution (Barking, Essex : 1987) pii:S0269-7491(25)00784-5 [Epub ahead of print].

Rapid climate change is often considered detrimental to biomineralization in mollusks; however, accumulating contradictory evidence necessitates reevaluation of the concept. Estuaries, characterized by fluctuating pH levels and limited calcifying substrate availability, are generally considered unfavorable for biomineralization. Understanding how biomineralization evolves in estuarine environments is essential for assessing adaptive potential and identifying mechanisms that could support molluscan adaptation to future environmental change. Phenotypic analyses, multi-omics approaches, and functional assays were employed within a common garden design to investigate the mechanisms underlying the estuarine oyster (Crassostrea ariakensis) adaptation to estuarine environments, using Pacific oysters (Crassostrea gigas), which inhabit non-estuarine areas, as a control. Compared with C. gigas, C. ariakensis exhibited superior biomineralization capacity, evidenced by heavier shells with increased density, enhanced resistance to dissolution, and greater toughness. Ion homeostasis and high expression of classical-pathway mantle secretomes were identified as compensatory mechanisms for the biomineralization adaptation of C. ariakensis. The novel C. ariakensis C-type lectin, a species-specific classical-pathway shell matrix secreted protein (SMSP), demonstrated a high capacity to accelerate the CaCO3 precipitation rate of calcite particles, thereby underscoring the essential roles of species-specific SMSPs in estuarine adaptations. This study provides novel insights into the adaptive potential of biomineralization in mollusks under rapid climate change. Analyzing biomineralization in estuarine organisms is critical for anticipating the emergent impacts of climate change.

ESP Origins

In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.

ESP Plans

With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.

Papers in Classical Genetics

The ESP began as an effort to share a handful of key papers from the early days of classical genetics. Now the collection has grown to include hundreds of papers, in full-text format.

Digital Books

Along with papers on classical genetics, ESP offers a collection of full-text digital books, including many works by Darwin and even a collection of poetry — Chicago Poems by Carl Sandburg.

Timelines

ESP now offers a large collection of user-selected side-by-side timelines (e.g., all science vs. all other categories, or arts and culture vs. world history), designed to provide a comparative context for appreciating world events.

Biographies
