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.

Global climatic co-suitability patterns of the predatory mite Anystis baccarum and green peach aphid Myzus persicae under climate change.

Experimental & applied acarology, 97(3):.

Understanding how climate change alters the geographic correspondence between pests and their natural enemies is important for identifying regions where climatic conditions may support further biological-control assessment. The whirligig mite Anystis baccarum (L.) is a generalist predator known to consume a variety of small arthropod pests, while the green peach aphid Myzus persicae (S.) is a globally invasive pest that damages a wide range of crops. However, the global climatic co-suitability and future geographic correspondence between A. baccarum and M. persicae remain poorly understood. Here, we constructed ensemble species distribution models to predict the climatic suitability and climatically co-suitable areas of both species under current climatic conditions and two climate scenarios for the 2050s, SSP1-2.6 and SSP5-8.5. The ensemble models showed high discrimination under repeated random validation, with AUC values of 0.984 and 0.980 and TSS values of 0.856 and 0.831 for A. baccarum and M. persicae, respectively. The minimum temperature of the coldest month (bio_6) was the most influential climatic predictor associated with the suitability of both species. Under current climatic conditions, predicted suitable areas for both species were concentrated mainly in the Northern Hemisphere, with Europe containing the largest suitable areas. By the 2050s, the total climatically co-suitable area is projected to increase by 3.1% under SSP1-2.6 and 4.3% under SSP5-8.5, while the suitable ranges of both species shift toward higher latitudes. However, A. baccarum is projected to lose suitable habitat within the current suitable range of M. persicae, indicating a possible climate-driven weakening of their geographic climatic correspondence in some regions. These findings identify broad-scale patterns of climatic co-suitability between M. persicae and A. baccarum and provide a climatic basis for prioritizing regions where the biological-control potential of A. baccarum can be evaluated further under changing environmental conditions.

Factors beyond anthropogenic climate change affecting airborne pollen levels in urban areas.

Journal of environmental management, 417:130949 pii:S0301-4797(26)02409-6 [Epub ahead of print].

Climate change is increasing airborne pollen concentrations, exposing populations to unprecedented allergenic levels and intensifying respiratory diseases. However, these changes are not exclusively climate-driven, particularly in urban environments where the structure, distribution, abundance and management of the vegetation is conditioned by human activity. This study provides an analysis of the temporal trends of airborne pollen levels from anthropically managed tree species in centres of high population density such as the metropolitan area of the Madrid Region (central Spain), one of the most densely populated in Europe. The study was done by evaluating the time trends in the Annual Pollen Integral and the number of days of allergenic risk throughout the 1996-2024 period, along with meteorological variables and changes in land cover, then integrating all this information using a Random Forest machine learning model. Results show a widespread increase over the two last decades. Notably, significant APIn increases reached up to 1200 and 2000 pollen grains*day/m[3]/year for Cupressaceae and Platanus, respectively. Moraceae showed the most consistent APIn increase with a maximum rate of change of 250 pollen grains*day/m[3]/year. Maximum temperature emerged as a key meteorological driver, showing consistent upward trends. Crucially, land-cover changes constitute a primary factor in airborne pollen loads and act synergistically with climate change. This highlights the critical role of urban growth and tree management. Consequently, mitigating this complex public health challenge requires multi-scale interventions, from large-scale urban planning to local green-space actions.

Reforestation Under Climate Change-A Cross-Regional Deadwood Retention Experiment to Develop Multifunctional Forests on Disturbed Norway Spruce Areas.

Ecology and evolution, 16(9):e74357.

Extreme events such as droughts, heatwaves, storms, and the associated intensification of bark beetle outbreaks in Norway spruce forests in recent years have led to large-scale forest loss in Central Europe. Various options for post-disturbance management exist, from complete clearing to no intervention, but their pros and cons in the context of multifunctional forest management remain unresolved. The interdisciplinary "ResEt-Fi" project ("Pioneering reforestation: Regional management for establishing multifunctional forests on post-disturbed Norway spruce areas") comprises a cross-regional field trial to test how specific practices of deadwood retention affect the ecological conditions and subsequent reforestation of natural and artificial regeneration. It aims at generating climate-stable mixed forests, balancing ecosystem functioning and socio-economic benefits. Rather than presenting a conventional empirical study with finalized results, we reflect upon an integrated and transferable research framework for investigating post-disturbance forest management across spatial scales. We present the rationale behind different deadwood management strategies, the nested experimental design of the cross-regional field trial, the ecological response framework, upscaling approaches, and future perspectives. Based on this scientific foundation, evidence-based recommendations and application scenarios can be developed to support forest managers and other stakeholders in selecting site-specific post-disturbance management strategies.

Mycotoxin contamination in food and feed: Occurrence, co-occurrence, combined impacts on human and animal health, climate change implications, risk assessment, and mitigation strategies.

Mycotoxin research, 42(4):.

Mycotoxins are toxic secondary metabolites produced by numerous fungi that infect crops during pre- and post-harvest stages. Aflatoxins, ochratoxins, fumonisins, zearalenone, and trichothecenes are of greatest concern due to their widespread occurrence and high toxicity. Consumption of mycotoxin-contaminated food and feed poses serious public health risks, as these compounds are linked to carcinogenic, neurotoxic, nephrotoxic, hepatotoxic, and immunotoxic effects. The frequent co-occurrence of multiple mycotoxins further amplifies health risks through additive or synergistic interactions and contributes to substantial economic losses. This review provides an updated overview of the global distribution and co-occurrence of major mycotoxins in agricultural products, their individual and combined toxicological effects on human and animal health, and the regulatory standards and maximum permitted levels for mycotoxins in food and feed. In addition, this review discusses the impact of climate change on mycotoxin contamination in food and feed, exposure, and associated health risks. It further outlines mycotoxin risk assessment procedures and highlights mitigation strategies for reducing contamination and limiting human and animal exposure risks. Ultimately, this review underscores the urgent need for integrated mycotoxin risk management strategies and strengthened global surveillance systems to safeguard food safety, protect human and animal health, and enhance food security.

Effects of an Online Education Program on the Competency of Korean Nurses in Responding to Climate Change: A Quasi-Experimental Study.

Journal of continuing education in nursing [Epub ahead of print].

BACKGROUND: Climate change is a critical health challenge that nurses must address. However, continuing education opportunities that prepare nurses to integrate climate change-health issues into practice remain limited. The goal of this study was to develop and evaluate an online education program to enhance nurses' competency in responding to climate change.

METHOD: A quasi-experimental pretest-posttest design examined the effectiveness of a 4-week, six-session online training program. Participants were 60 Korean nurses working at three general hospitals (intervention group = 29; control group = 31). Data were collected three times between September and November 2023.

RESULTS: After the intervention, significant differences were observed between the intervention and control groups in motivation, self-efficacy, and climate change-health nursing practice.

CONCLUSION: The education program developed in this study potentially can be used to train nurses across various hospital settings, enhancing their competencies in climate change-health responses.

Climate change in the workforce: A systematic review of knowledge, attitudes and practices among vulnerable workers categories.

Public health, 259:106494 pii:S0033-3506(26)00363-X [Epub ahead of print].

OBJECTIVES: To map the existing literature on knowledge, attitudes, and practices (KAP) regarding climate change among workers vulnerable to climate-related occupational risks.

STUDY DESIGN: Systematic review of cross-sectional studies.

METHODS: We performed a systematic review of survey-based cross-sectional studies. We searched PubMed, Scopus, and Google Scholar for articles published between January 2000 and December 2025. Eligible studies reported measurable outcomes for at least one KAP component related to climate change. Methodological quality was assessed using the Joanna Briggs Institute checklist for analytical cross-sectional studies. KAP patterns were analyzed according to occupational sectors, geographic regions, and worker characteristics.

RESULTS: Among 2126 records, we included 19 studies, covering a sample of 10,000 workers, mainly engaged in agriculture. Most studies reported high awareness of climate variability (84.2%) and perceived vulnerability (78.9%), while adoption of at least one adaptive practice was observed in 68.4% of articles. A knowledge-practice gap emerged in one-quarter of the evidence. Adaptation among farmers included agronomic and livestock management strategies, often influenced by access to education and resources. In contrast, surveys on construction and informal workers reported more limited knowledge of heat-related health risks and reliance on individual coping behaviors, with few employer-led protective measures.

CONCLUSION: Evidence on workers' knowledge, attitudes, and practices regarding climate change remains limited and uneven. Future studies should include a broader range of highly exposed occupational groups, beyond agriculture. Although workers report high awareness and risk perception, this does not consistently translate into preventive practices, reflecting structural and institutional barriers. Strengthening research and implementing workplace-level protections and occupational health policies addressing climate-related risks is essential.

Multiscale assessment of transboundary water-food-energy nexus under climate change in Irtysh River Basin.

iScience, 29(9):117374.

Climate change is intensifying water scarcity and amplifying upstream-downstream tensions in transboundary river basins, particularly in Central Asia. We present a multiscale framework integrating hydrological dynamics with the water-food-energy (WFE) nexus to assess climate-driven cross-sectoral trade-offs in Irtysh River Basin. By combining long-term hydroclimatic observations with climate projections, we quantified the effects of temperature and precipitation variability on runoff and evaluated how these changes propagate across interconnected WFE systems. Climate-induced hydrological changes increased irrigation demand, reduced hydropower potential, reshaped agricultural productivity, and intensified regional resource pressures, with distinct responses between upstream and downstream regions. These findings reveal pronounced spatial heterogeneity in climate vulnerability and adaptive capacity, highlighting the need for differentiated adaptation strategies and coordinated transboundary governance. Our study establishes a transferable framework for assessing climate change impacts across the WFE nexus, providing actionable insights for enhancing climate resilience and sustainable resource governance in transboundary river basins.

Cardiovascular diseases attributed to future heat and cold: A projection study of climate change impact under different scenarios in an arid region of Iran, Esfarayen.

International journal of biometeorology, 70(9):.

Climate and temperature changes are among the most critical challenges for human and planetary health; however, evidence on future temperature-related health impacts remains limited in the Middle East and other arid regions. This study quantified historical and projected heat and cold-related cardiovascular morbidity (i.e., hospital admissions) in an arid region of Iran under multiple climate, population, and adaptation scenarios. Daily cardiovascular disease counts were associated with temperature using a quasi-Poisson regression within a distributed lag non-linear model (DLNM), which was then combined with historical and projected temperature data (1981-2099) obtained from the ISIMIP database under RCP2.6, RCP4.5, and RCP8.5 scenarios. In addition to station-based observations, air temperature was predicted using land surface temperature (LST) within a semi-parametric regression framework. Population change was incorporated using United Nations low- and high-fertility variant scenarios. Adaptation was modeled as a 20% upward shift in the minimum-CVDs temperature and compared with a no-adaptation scenario. Results showed that heat-attributable cardiovascular morbidity is projected to increase by more than 30% in several mid- and late-century decades, particularly under RCP8.5, whereas cold-attributable morbidity remains negligible (< 1%) and highly uncertain. Adaptation and population change had low effects on the attributable fraction, while the use of LST-derived air temperature resulted in more conservative risk estimates compared to station-based data. These findings highlight substantial future heat-related cardiovascular risks and emphasize the need for heat-specific urban planning and improved exposure modeling in projection studies, especially in arid regions.

Climate change and animal infectious diseases: a systematic review of emerging evidence.

The Lancet. Planetary health pii:S2542-5196(26)00097-5 [Epub ahead of print].

Climate change is increasingly recognised as a major driver of infectious disease dynamics, yet its impact on animal health remains understudied compared with its impact on human populations. This systematic review aimed to assess the effects of climate variability and change on the epidemiology of animal infectious diseases, focusing on measurable changes in disease incidence, prevalence, mortality, and geographical distribution. We searched PubMed and CAB Abstracts for studies published between Jan 1, 1970, and Dec 31, 2024, and identified 33 eligible studies that that assessed associations between climatic factors and observed disease outcomes in animal populations. The evidence base has grown over the past decade but remains geographically and taxonomically imbalanced. Most (24 [73%] of 33) studies reported positive associations between climatic variables and increased disease risk, expanded geographical ranges, or higher prevalence. Vector-mediated mechanisms were consistently proposed as underlying drivers (25 [76%] of 33). Domestic species were the most frequently studied hosts (18 [55%] of 33), whereas wildlife hosts were under-represented (11 [33%] of 33). Four studies (12%) included mixed host populations. 6200 studies identified by our search were excluded because they relied solely on environmental suitability indices, vector abundance models, or synthetic epidemiological outcomes, highlighting a persistent scarcity of longitudinal empirical disease data linked to long-term changes in weather and climate. Although modelling approaches are valuable for risk projection, the poor availability of longitudinal epidemiological data constrains validation and attribution. Overall, the available evidence suggests that climate variability and change are reshaping animal infectious disease epidemiology, with important implications for animal health, food security, and zoonotic risk. However, important gaps in our understanding of these dynamics remain. Bridging these gaps, strengthening climate-aware surveillance, expanding data accessibility, and integrating animal health into One Health strategies will be essential to address emerging health risks.

Climate change and poultry production in Africa: a systematic scoping review of climate resilience and adaptation strategies.

Poultry science, 105(12):107634 pii:S0032-5791(26)01268-X [Epub ahead of print].

Climate change poses several challenges to the sustainability of poultry production in Africa, affecting both biological performance and economic viability within different agro-ecological zones. This scoping review synthesises existing literature on climate impacts, adaptation mechanisms, and policy frameworks across four representative African agro-ecological regions. The analysis revealed that climate stress factors such as heat stress, drought, and unpredictable rainfall have measurable impacts on poultry production systems across Africa. For example, in Tanzania, drought and irregular precipitation were linked to a 15-20% decline in the biomass of scavenging feed and a 25% increase in chick mortality rates. In Nigeria, heat stress led to a 15-25% decrease in feed intake and a 20-30% decline in egg production. In South Africa, drought and heatwaves caused a 10-12% increase in poultry mortality rates and a rise in operational costs associated with cooling and water provision. In Egypt, reliance on imported feed made poultry producers vulnerable to market shocks caused by climate change, with feed prices increasing by more than 45%. The negative effects include decreased food security and the livelihoods of farmers, as well as a higher cost of production. Various adaptation strategies have improved the resilience of poultry production systems, although these methods are not very efficient due to various limitations. Synthesis of the literature highlights four primary intervention pathways evaluated across regional studies: localized feed systems, technology-enabled early warning frameworks, renewable energy integration, and alternative protein sourcing. Therefore, further improvements are needed to enhance the resilience of the poultry industry in Africa.

Habitat Shifts and Conservation Challenges of Falconidae Under Climate Change in Northwestern China.

Animals : an open access journal from MDPI, 16(17):.

Xinjiang's distinctive geography and climate provide important habitats for Falconidae species, yet their climate-driven habitat shifts and conservation gaps remain poorly understood. Using 2731 validated occurrence records and 26 environmental predictors, including bioclimatic, land-use, topographic, hydrological, anthropogenic, and Normalized Difference Vegetation Index (NDVI) predictors, we applied an optimized Maximum Entropy (MaxEnt) framework to project suitable habitats for seven falconid species under current conditions and three Shared Socioeconomic Pathway scenarios (1-2.6, 2-4.5, and 5-8.5) for 2041-2060, 2061-2080 and 2081-2100. Barycenter migration analysis, the Habitat Quality module of the Integrated Valuation of Ecosystem Services and Tradeoffs framework, and protected-area overlays were further integrated to identify conservation priorities. All models showed high discriminatory performance, with mean areas under the receiver operating characteristic curve exceeding 0.90. Current suitable habitats were mainly concentrated along river corridors and mountain foothills in the southern Altai, central-western Tianshan and northern Kunlun regions. Future responses were strongly species-specific. By 2081-2100 under Shared Socioeconomic Pathway 5-8.5, suitable habitat increased by 154.6% for Falco peregrinus and 79.5% for Falco tinnunculus but declined by 81.1% for Falco vespertinus; Falco subbuteo also showed overall expansion, with its suitable-habitat barycenter shifting by up to 291.9 km. Mean relative habitat quality was 0.514 [standard deviation = 0.185], while suitable habitat outside protected areas ranged from 35,346 to 304,866 km[2] among species, and high-quality priority conservation gaps reached 102,489 km[2] for Falco cherrug. These results demonstrate that climatic suitability does not necessarily correspond to high habitat quality or adequate protection and support species-specific, climate-adaptive conservation strategies for falconids in Xinjiang.

Impacts of Climate Change and Adaptation Strategies on Maize Yield in Kenya and Northwest China.

Plants (Basel, Switzerland), 15(17):.

Climate change poses growing risks to maize-based food systems, yet comparative evidence across climatically similar regions on different continents remains limited. This study compares climate change impacts and adaptation responses in rainfed maize systems in Nakuru County, Kenya, and Northwest China-two geographically distant but climatically similar regions. The CERES-Maize model (DSSAT v4.7), the latest version available when this study was conducted, was calibrated and validated using observed phenology and grain yield data (2005-2009) from Agricultural Meteorological Experimental Stations. Independent evaluation confirmed excellent model performance, with a normalized root mean square error (NRMSE) of less than 10%. The model was driven by bias-corrected climate projections under RCP4.5 and RCP8.5 for the 2030s (2021-2040) and 2050s (2041-2060), relative to the 1986-2005 baseline. Changes in climate, maize phenology, and yield were quantified, and adaptation strategies were evaluated against the baseline. Warming and increased precipitation accelerated maize development, causing yield declines of 3-27% in Nakuru County and 5-22% in Northwest China, with larger losses under RCP8.5. Adaptation measures-including planting-date adjustments, supplemental irrigation, and late-maturing cultivars-increased yields by up to 39% in Kenya and 29% in Northwest China, with combined strategies outperforming individual measures. Coordinated, multi-strategy adaptation can offset a large share of projected yield declines, offering practical pathways to sustain maize productivity under future climate change.

Predicting the Potential Distribution of Plantago asiatica L. in Jiangxi Province Under Climate Change Scenarios Using the MaxEnt Model.

Plants (Basel, Switzerland), 15(17):.

Plantago asiatica L. is an important medicinal and edible plant in China, whose wild resources have declined sharply due to overharvesting. Accurately assessing its potential suitable habitats and identifying the dominant environmental factors are of great scientific significance for germplasm conservation. In this study, we focused on Jiangxi Province and, based on 79 field occurrence records and 29 environmental variables, employed a MaxEnt model optimized using the kuenm package (version 1.1.9) (AUC = 0.806) to simulate the potential distribution of this species under current and three future Shared Socioeconomic Pathway (SSP) scenarios (SSP126, SSP370, and SSP585). The results indicated that static non-climatic factors at the regional scale-specifically, soil clay content (contribution rate: 56.7%)-were the dominant force determining the distribution of Plantago asiatica, with an influence far exceeding that of climatic and topographic factors. Under all future SSP scenarios, its distribution range exhibited notable spatiotemporal conservatism, and the centroid showed no long-distance migration. This study provides a scientific reference for optimizing the conservation framework of Plantago asiatica germplasm resources, identifying priority cultivation areas, and formulating regional adaptive management strategies.

Climate Change Impact on the Potential Distribution and Invasion Risk of Tetramorium caldarium (Roger, 1857): A Species Distribution Modeling Approach Using MaxEnt.

Ecology and evolution, 16(9):e74319.

Climate change is reshaping global species distributions and altering invasion dynamics, yet our understanding of how thermophilic invasive species will respond to future climatic conditions remains incomplete. We employed Maximum Entropy (MaxEnt) species distribution modeling to evaluate current and future suitable habitat for Tetramorium caldarium (Roger, 1857), a pantropical tramp ant species with established exotic populations across six continents. Three hundred and forty-six filtered occurrence records and five bioclimatic variables (bio_1, bio_4, bio_7, bio_11, bio_12) were selected through correlation analysis. Models were projected onto future climate surfaces using MRI-CGCM3 outputs for two Representative Concentration Pathways (RCP 2.6 and RCP 8.5) at 2050 and 2070. The model demonstrated excellent predictive performance (AUC = 0.942, TSS = 0.68), revealing that T. caldarium currently occupies extensive suitable habitat across tropical and subtropical regions between 30° N and 30° S. Three-dimensional niche analysis demonstrated remarkable climatic breadth, with the species occurring across temperature gradients from 14°C to 29°C and precipitation regimes from 500 to 3500+ mm annually. Jackknife analysis revealed that temperature seasonality (43.7%) and coldest quarter temperature (25.9%) were primary limiting factors, while precipitation contributed minimally (4.5%). Future projections indicated relatively stable core distributions through 2070, with net habitat gains ranging from 275,000 km[2] (RCP 2.6, 2050) to 630,000 km[2] (RCP 8.5, 2070). Southern China, southeastern United States, Mediterranean Basin, and northern Argentina were identified as high-risk regions for future spread. T. caldarium possesses sufficient climatic niche breadth to maintain its spread potential despite climate change, with warming temperatures creating new opportunities in temperate regions. These findings emphasize that preventing human-mediated dispersal remains more critical than managing climate-driven range shifts for this globally significant invasive species.

Distribution and Habitat Suitability of Artemisia annua in China Under Climate Change Scenarios.

Ecology and evolution, 16(9):e74236.

Artemisia annua is a medicinal plant of high therapeutic and economic value, yet its wild resources have declined markedly in recent decades. Climate change is expected to further alter its geographical distribution, posing challenges to both conservation and sustainable utilization. Here, we applied a Maximum Entropy (MaxEnt) model that integrates climatic, topographic, and soil variables to assess the current and future suitable habitats of A. annua in China under three CMIP6 shared socioeconomic pathways (SSP126, SSP245, and SSP585) for the mid-21st century (2050s) and late-21st century (2090s). We hypothesized that winter temperature conditions and precipitation seasonality would be the principal climatic constraints on habitat suitability, and that future climate change would drive an overall contraction and northeastward shift of suitable areas, with stronger changes under higher-emission scenarios. The model was optimized using the ENMeval framework by tuning the regularization multiplier and feature classes, thereby reducing overfitting and improving ecological realism. Model predictions indicate that the current suitable habitat of A. annua covers approximately 2.02 × 10[6] km[2], mainly distributed across central and southwestern China. Habitat suitability is primarily constrained by winter temperature conditions, precipitation seasonality, and elevation, highlighting the dominant role of climatic tolerance and topographic mediation in shaping its ecological niche. Under future climate scenarios, the total suitable area is projected to contract, with the most pronounced reductions occurring under the high-emission SSP585 pathway. Spatially, suitable habitats are expected to shift northeastward, with the centroid migrating from northern Sichuan toward southern Shaanxi, reflecting a climate-driven redistribution toward cooler regions. By distinguishing stable, contracting, and expanding zones of suitable habitat, this study provides a spatially explicit assessment of A. annua's vulnerability and adaptive potential under climate change. Our findings offer ecological insights into the species' climate sensitivity and provide a scientific basis for dynamic conservation planning and sustainable industrial distribution under future environmental change.

Land Use Diversification to Enhance Livelihood Resilience in the Face of Climate Change in Ethiopia.

TheScientificWorldJournal, 2026(1):e8444736.

This study examines how different land use systems are associated with resilience to drought-induced food insecurity in Ethiopia using a comparative case study of three districts representing monocropping (Bale), agroforestry (Sidama), and woodlot-based systems (Awi). The analysis integrates crop damage data from the Central Statistical Agency (CSA) with food aid priority classifications and postdrought food security outcomes from the Integrated Food Security Phase Classification (IPC) and food aid priority area map from World Food Program (WFP), Inter-Agency Humanitarian Evaluation (IAHE) and United Nations Office for the Coordination of Humanitarian Affairs (OCHA). Results show marked differences in drought impacts across systems. During the 2015-2016 drought, Bale (monocropping) experienced the highest crop losses (54,354 ha; 0.29 ha per affected person), followed by Sidama (agroforestry) (6629 ha; 0.19 ha per person) and Awi (woodlot) (3802 ha; 0.02 ha per person). Normalized against projected 2016 zone populations, Bale also records the highest area loss per 1000 inhabitants (30.8 ha, vs. 3.1 in Awi and 1.8 in Sidama), although the share of the zone population reporting crop damage was highest in Awi (15.4%). Postdrought IPC classifications further indicate higher food insecurity in Bale, where 60% of the population was classified in Phase 2 or above, compared with 30% in Sidama, whereas Awi did not meet the threshold for IPC classification. These patterns suggest that, within the studied contexts, diversified land use systems particularly agroforestry- and woodlot-based practices are associated with lower exposure to drought impacts and reduced food insecurity. However, these relationships are context-specific and reflect the combined influence of land use systems and broader agroecological and socioeconomic conditions. In particular, mean annual rainfall differs more than twofold across the study districts, and the woodlot district is also the wettest, so baseline moisture availability cannot be separated from land use configuration as an explanation of the observed differences. The findings are therefore indicative rather than causal, but they highlight the potential role of land use diversification as part of strategies to enhance resilience to climate variability.

Symbiotic interactions and climate change implications of the octocoral microbiome.

The ISME journal pii:8796024 [Epub ahead of print].

Octocorals are vital components of tropical, temperate, and cold-water benthic marine ecosystems. Their associated microbiomes, comprising microeukaryotes, prokaryotes, and viruses, are increasingly recognised as central to host health, nutrient cycling, and chemical defence. Metagenomics and amplicon sequencing have uncovered taxonomic and functional complexity within these microbial communities, revealing patterns of host specificity and health status, along with seasonality and geographic structuring. However, anthropogenic stressors, particularly those associated with global climate change, exert intense pressure on coral-dominated ecosystems, leading to complex and poorly understood local and regional patterns of octocoral expansion and mortality. Microbial interactions may be a main driver of these contrasting outcomes by mediating the ecological resilience of octocorals to environmental stress. We synthesise the current state of research on the diversity, organisation, and function of the octocoral microbiome, and identify critical knowledge gaps on octocoral holobionts relative to scleractinian corals. Our meta-analysis of 79 publicly available bacterial genomes from octocorals reveals group-specific specialisation in denitrification and nitrate assimilation, along with widespread capacities for essential amino acid, cofactor, and vitamin production, suggesting important contributions to nutrient cycling in the holobiont. While sampling efforts between cultured and uncultured lineages are even, our genomic survey reveals strong sampling bias toward the Atlantic Ocean, temperate gorgonians, and healthy host states, whereas bacterial genomes representing the pathobiome, tropical and/or deep-sea regions, and other octocoral taxa remain underrepresented. Accordingly, we propose future research directions to advance understanding of octocoral microbiome ecology and its role in the resilience of tropical, temperate and cold-water coral reefs.

How behavioural changes can help deal with the health impacts of climate change to achieve SDG 13 (climate action).

Applied psychology. Health and well-being, 18(5):e70221.

Climate change is a major public health issue in the 21st century, and the links between climate change and health are increasingly becoming recognised by researchers and policy-makers. Interventions aimed at promoting sustainable behaviours, that is, reducing harmful activities and inducing pro-environmental action as well as adaptive capacities, can be diverse in targeting changes in culture, feedback loops and technological development. A focus on changing both individual and collective behaviours is indispensable to reduce the negative impacts on health. This overview outlines the connections between climate change, health and behavioural change and discusses how such changes can assist in efforts towards handling the impacts of climate change. This is of particular relevance as it relates to achieving the Sustainable Development Goal (SDG) 13 (Climate Action) and, simultaneously, contribute also to SDG 3 (Good Health and Well-being). Focusing on the health benefits of pro-environmental action today may pave the way for improvements. A holistic climate change response, however, needs to consider health concerns from a multisectoral perspective and engage stakeholders at all levels-from neighbourhood communities to international structures as health challenges linked to climate change intensify.

Evolution of flowering phenology over 44 years of climate change.

Proceedings of the National Academy of Sciences of the United States of America, 123(37):e2613665123.

Evolution is expected to be crucial for the persistence of some populations exposed to changing climate, but demonstrations of rapid evolution in wild populations associated with ongoing climate change are scarce. Inferences about possible adaptive responses rest heavily on "space-for-time" approaches that are fraught with assumptions that are difficult to verify. In contrast, resurrection experiments offer a direct method to observe evolutionary changes over time but rarely span the periods of several decades over which climatic shifts have occurred. In this study, we integrated space-for-time, environmental manipulation, and resurrection experiments to investigate the evolution of the annual plant Lactuca serriola following 44 years of climate change in Israel and the Golan Heights. We found that contemporary plants flowered over 7 d earlier, a putative adaptation to increasingly warm and dry conditions, and also flowered earlier under experimental drought. However, in contrast to these patterns, plants originating from wetter populations flowered earlier than those from drier populations, indicating a mismatch between space-for-time predictions and observed temporal shifts in phenology. Our findings provide direct evidence for evolution in response to climate change in a wild species, while cautioning against applying predictions made from space-for-time studies to future climate change responses.

Translating Bioengineering Principles to Coral Reef Restoration Under Climate Change.

Annual review of marine science [Epub ahead of print].

Coral reefs support immense biodiversity and human well-being, yet accelerating environmental change is driving unprecedented losses of habitat-forming hard corals in recent decades and demands new strategies to strengthen reef resilience. Advances in bioengineering are expanding the controllable parameter space of living systems, enabling intervention at genetic, cellular, and microenvironmental scales, thereby creating new possibilities for scalable coral reef restoration. In this review, we synthesize recent bioengineering advances applied to coral restoration, focusing on key bottlenecks such as recruitment limitation, outplant survivorship, bleaching susceptibility, and early mortality These approaches include controlled-release surfaces for inductive settlement signals, antifouling and growth-optimized substrates, modular biofabrication platforms, targeted microbiome manipulation, and nanomaterial-mediated mitigation of oxidative stress. We argue that, if successfully translated at scale, bioengineering approaches could prove transformative for sustaining reef ecosystem function under accelerating climate change.

Nonlinear response of vegetation productivity to climate change and human activities in a water-source basin: implications for environmental health and water security.

Frontiers in public health, 14:1868335.

INTRODUCTION: Gross primary productivity (GPP) is a key component of the global carbon cycle, and its dynamics are influenced by climate conditions and human activities. However, the nonlinear response of GPP to climate change and human activities remains unclear. The Hanjiang River Basin (HJRB), a crucial water-source region of the South-to-North Water Diversion Project in China, is vital to China's ecological security. Changes in vegetation productivity in this water-source basin may affect water conservation, soil erosion control, drought and flood regulation, and the environmental conditions to which downstream populations are exposed. In recent decades, the region has experienced significant climate change, intensified human activities, and notable increases in vegetation greenness. However, previous literature relying on the assumption of stationarity and traditional linear methods has limited capability in detecting nonlinear and gradual vegetation changes.

METHODS: The long-term nonlinear trend in GPP in the HJRB was analyzed using ensemble empirical mode decomposition (EEMD), and the nonlinear response relationships among climatic factors, human activities, and GPP were further quantified using the LightGBM machine-learning method.

RESULTS: From 2000 to 2020, the annual growth rate of vegetation productivity in the HJRB was 12.27 g C m[-2] yr[-1] (P < 0.01). Most vegetated areas exhibited an upward trend in GPP. However, 28.25% and 4.41% of the region experienced transitions from growth to decline and from decline to growth, respectively, primarily in the southern upstream and eastern downstream areas. Drought (25.28%), precipitation (10.75%), and relative humidity (10.69%) were identified as significant factors influencing vegetation productivity trends. Annual precipitation above approximately 1,000 mm was associated with lower SHAP values for the continuous-increase trend, which may reflect combined hydrothermal, radiation, and topographic constraints rather than a direct inhibitory effect of precipitation. Additionally, an increase in SPEI12 was associated with higher SHAP values for the continuous-increase trend.

DISCUSSION: This study elucidates trends and underlying response patterns in vegetation productivity in the HJRB, reveals the driving factors behind regional vegetation productivity changes, and provides environmental evidence for vegetation monitoring, water-source ecosystem management, and climate-related health-risk prevention in the HJRB and similar water-source regions.

University students in the era of climate change: climate distress is associated with academic burnout and engagement through academic amotivation.

Frontiers in psychology, 17:1878132.

INTRODUCTION: Climate change has measurable impacts on the psycho-physical health of individuals, with disproportionate effects on current and future youth cohorts. Many young individuals experience climate distress, characterized by negative emotions and thoughts related to climate change that can impact their daily lives. Although previous studies have documented how climate change has increased concerns regarding academic careers, no research has explored how climate distress may compromise students' adjustment in terms of burnout and engagement. Furthermore, no studies have examined the motivational processes that could explain this relationship. Therefore, the present study examined, within a unified model, the relationships among climate distress, engagement, and burnout, hypothesizing that these relationships occur through academic amotivation. Specifically, it was hypothesized that climate distress would be associated with increased academic burnout and decreased engagement through academic amotivation.

METHODS: A convenience sample of 375 university students, aged 18-37 years (M = 21.64, SD = 2.28), was involved, and a path analysis model was tested to verify the formulated hypotheses.

RESULTS: The results confirmed the indirect association between climate distress and both engagement and academic burnout through academic amotivation. Specifically, climate distress was associated with increased academic amotivation, which in turn, was associated with lower engagement and higher burnout.

DISCUSSION: The findings highlight an association between climate distress and academic maladjustment among university students, underscoring the pivotal role of academic amotivation. The results indicate the importance of addressing climate distress in academic contexts considering the negative repercussions that may affect students' wellbeing and academic career trajectories.

Hydrogeomorphic hazards and vulnerability assessment through basin morphometry in the climate change sensitive western Himalayan syntaxis: A case study of the Astore river basin.

The Science of the total environment, 1051:182303 pii:S0048-9697(26)00971-X [Epub ahead of print].

This study presents a hydrogeomorphic hazard and vulnerability assessment of the Astore river basin in the western Himalayan syntaxis. Hydrogeomorphic hazards i.e. debris flows, debris floods, and fluvial floods, pose significant risks to local communities and infrastructure. Prior recognition of specific flow types is crucial because different flow types require specific remedial measures. To achieve this objective, the Astore river basin was initially divided into 65 sub-basins using field data and high-resolution satellite imageries, enabling the identification of sub-basins generating debris flow, debris flood, and fluvial flood. This field-based classification was validated through statistical analysis of selected morphometric parameters, including basin Melton's ratio, basin relief ratio, basin area, basin length, basin gradient, basin channel length, and fan gradient. Threshold values were established for all the morphometric parameters through cross-correlation plots to differentiate sub-basin-scale hydrogeomorphic hazard types. Morphometric analysis of parameters with >90% predictive accuracy revealed distinct signatures for each sub-basin and hazard type. Debris flow-generating sub-basins are typically small (basin area < 10 km[2]), steep (fan gradient > 10°), with high basin Melton's ratio (> 0.60) and basin relief ratio (>0.37). Conversely, fluvial flood-generating sub-basins are larger, less steep, having low basin Melton's ratio (< 0.30), low basin relief ratio (< 0.37), large basin area (> 10 km[2]), and gentle fan gradient (< 5°). Debris flood-generating sub-basins occupy an intermediate range. Integration of morphometric analysis outcomes with glacial lake and human settlement inventories and the spatial distribution of loose debris cover was assessed to produce comprehensive hazard and vulnerability maps at sub-basins level, providing critical insights for risk reduction and sustainable development planning in the tectonically active and climate-vulnerable Himalayan regions.

Climate Change and Cardiovascular Complications of Diabetes.

Current diabetes reports, 26(1):.

PURPOSE OF REVIEW: Climate change is emerging as a clinically relevant driver of cardiometabolic risk, particularly among individuals with diabetes. Increasing frequency and severity of extreme weather events, including heat waves, cold exposure, and air pollution, can disrupt physiological homeostasis and access to essential healthcare resources. People with diabetes are uniquely vulnerable due to impaired thermoregulation, increased risk of dehydration, and high prevalence of cardiovascular and kidney disease.

RECENT FINDINGS: Temperature extremes impose significant cardiovascular stress. Heat exposure promotes dehydration, hemoconcentration, and increased cardiac workload, contributing to ischemia, arrhythmia, and heart failure. Cold exposure increases vascular resistance and blood pressure, further elevating cardiovascular risk. In parallel, air pollution and wildfire smoke amplify systemic inflammation, oxidative stress, and endothelial dysfunction, accelerating atherosclerosis and increasing the likelihood of acute cardiovascular events. Clinical risk is further modified by age, comorbidities, socioeconomic factors, and access to healthcare infrastructure. Clinically, these findings support anticipatory management strategies, including patient education on heat and cold exposure, proactive medication adjustment, and closer monitoring during periods of environmental stress. Effective mitigation requires a multilevel approach, including patient education, medication management, disaster preparedness, and climate-resilient health systems. Integrating environmental data into clinical care and the use of predictive tools may enable proactive risk reduction. Climate change should be recognized as an emerging cardiovascular risk multiplier in diabetes, requiring coordinated action across clinical care, public health, and policy.

Climate change reshapes the global distribution of wild barley relatives: integrating life-history traits and ecological niche modeling.

Frontiers in plant science, 17:1935270.

INTRODUCTION: Wild Hordeum species are crucial genetic resources for climate‑resilient crop breeding. Clarifying their responses to climate change is essential for germplasm conservation and sustainable crop improvement. This study aims to elucidate the divergent climatic responses of wild Hordeum species and provide scientific evidence for germplasm protection and climate‑adaptive crop breeding.

METHODS: This study was conducted at a global scale, covering the major distribution areas and diversity hotspots of wild barley. We combined life‑history traits, niche breadth, and interspecific habitat overlap, and adopted MaxEnt species distribution models with CMIP6 climate datasets to project the spatiotemporal dynamics of suitable habitats for 13 wild Hordeum species. The ENMeval package was used for systematic parameter calibration and sensitivity analysis to optimize model configurations and ensure reliable predictive performance.

RESULTS: The model showed strong performance (mean AUC = 0.907 ± 0.029, TSS = 0.763 ± 0.064). Four global diversity hotspots were identified: southwest and central Asia, the Mediterranean region, western North America, and the Andes Mountains. Niche breadth and climate vulnerability are phylogenetically structured, with closely related species sharing similar ecological constraints and extinction risks. By 2100, wild Hordeum's global suitable habitat is projected to contract by ~62%, with annual species suffering greater losses than perennials. Hordeum spontaneum will suffer the most severe range contraction (97.83% habitat loss, threatening wild population persistence), while Hordeum muticum shows moderate resilience (36.96% reduction) and Hordeum agriocrithon will expand by 34.84%. Habitat migration is primarily driven by precipitation gradient variation, and stable niche overlap among closely related species verifies the edge adaptation hypothesis.

DISCUSSION: Wild Hordeum species exhibit divergent climate change responses. These contrasting habitat change trajectories signal divergent conservation urgency: extreme contractions threaten genetic erosion in crop wild relatives, whereas expanding ranges highlight potential donor species for climate‑adaptive breeding. High‑risk taxa such as Hordeum stenostachys require urgent coordinated in‑situ and ex‑situ conservation to prevent population decline and genetic erosion. In contrast, range‑expanding species (Hordeum agriocrithon) offer insights into adaptive mechanisms, with practical implications for climate‑resilient crop breeding. Notably, these projections reflect climatic suitability under a single climate model and should be interpreted cautiously given unmodeled biotic interactions and dispersal constraints.

Climate Protection and Climate Change Adaptation in Residential and Nursing Homes: Perspectives and Fields of Action from Expert Interviews.

Gesundheitswesen (Bundesverband der Arzte des Offentlichen Gesundheitsdienstes (Germany)) [Epub ahead of print].

BACKGROUND: Climate change is increasingly affecting the health of vulnerable population groups, particularly older adults living in residential and nursing homes. Heat, extreme weather events, air pollution, altered allergen exposure and other climate-related factors increase the risk of dehydration, cardiovascular diseases, infections, psychological strain and social isolation. At the same time, the health sector itself is a significant emitter of carbon dioxide (CO2) and is particularly vulnerable due to demographic changes and rising care needs.

METHODS: Interviews with experts from residential and nursing homes were conducted and analysed regarding their content. The aim was to identify fields of action at the interface of climate protection and health promotion, to analyse synergies between environmental and health objectives, and to derive practice-oriented recommendations.

RESULTS: The interviews show that residential and nursing homes have gained initial experience with climate protection and climate change adaptation, for example through energy-efficient measures, sustainable dietary practices, ecological cleaning agents and climate-control devices. Future challenges include limited financial resources, shortages of skilled staff, high workload, insufficient medical care, as well as the implementation of waste reduction, reusable systems and digital solutions. Structural adaptations such as sun protection, cooling, greening and heat emergency plans are considered essential for the well-being of residents and the relief of staff. Health professionals, particularly nurses, therapists and dieticians, play a key role as multipliers by raising awareness, supporting residents and implementing strategies in everyday practice.

CONCLUSIONS: Integrated climate and health management in residential and nursing homes can reduce exposure to climate-related risks, promote the health of residents and staff, and decrease the CO₂ footprint. Prioritised, strategically anchored measures, continuous monitoring and targeted training strengthen resilience and equity of opportunity. Residential and nursing homes can thus serve as a central lever for realising synergies between climate protection, health promotion and social responsibility.

Nationwide economic impacts of sea level rise and storm surge from global warming in Australia.

Scientific reports, 16(1):.

Driven by global warming and thermal expansion of the oceans, ice loss from glaciers and ice sheets will continue to increase sea levels and the risk of storm-surge, threatening coastal regions worldwide. This study presents the first national-scale assessment of SLR/S impacts on land use and assets across Australia, covering 1,156 coastal sub-regions in six states and the Northern Territory under RCP4.5 and RCP8.5 scenarios. The analysis integrates physical and economic impacts across 10 aggregated land-use categories. By 2100, under RCP4.5, SLR/S is projected to affect 267.5 thousand properties and 2.0 million hectares (ha) of land, resulting in present-value damages of $855.1 billion, including $274.3 billion in property losses and $580.7 billion in land-use losses. Under RCP8.5, impacts increase to 719.6 thousand properties and 3.7 million ha, with total damages of $1,909 billion, comprising $705.7 billion in property losses and $1,203 billion in land-use losses. The results reveal substantial spatial heterogeneity in physical exposure and economic impacts across Australia. Average annual SLR/S damages are estimated to reduce national GDP by 1.05-1.39% under RCP4.5 and 2.26-3.0% under RCP8.5. These estimates are conservative, as they exclude additional losses to environmental assets, cultural heritage, and other infrastructure not captured in the assessment.

The Effects of Environmental Health Literacy and Climate Change-Health Perception on Climate Change-Health Nursing Practice Among Korean Community Health Practitioners: A Descriptive Correlational Study.

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

BACKGROUND: The climate crisis is among the most pressing public health threats of the 21st century, and the climate-health competencies of primary care nursing personnel serving medically underserved areas are a critical determinant of community resilience. Korean Community Health Practitioners (CHPs), established in 1980 under the Special Measures Act for Public Health and Medical Services in Rural Areas, have provided primary health care (PHC) in medically underserved rural regions for over 40 years; however, their environmental and climate-health competencies have rarely been studied.

AIMS: This study examined the effects of Environmental Health Literacy (EHL) and Climate Change-Health Perception on Climate Change-Health Nursing Practice among Korean Community Health Practitioners.

DESIGN: A descriptive cross-sectional correlational study.

METHODS: Of 1,899 health practice posts nationwide as of 2023, we recruited Community Health Practitioners working in 567 health practice posts located in two administrative regions (J Special Self-Governing Province and J Province). Data were collected via a structured online survey from September 24 to October 31, 2024, yielding a final analytic sample of 144 participants. We administered the Korean Environmental Health Literacy scale (K-EHL, 38 items), the Korean version of the Climate, Health, and Nursing Tool (K-CHANT) Awareness/Concern/Motivation subscales (12 items), and a 32-item Climate Change-Health Nursing Practice checklist developed by Park (2024). Descriptive statistics, independent t-tests, one-way ANOVA with Scheffé's post-hoc test, Pearson correlations, and multiple regression were performed using SPSS 28.0.

RESULTS: Mean scores (out of 5) were 3.81 ± 0.34 for EHL, 4.23 ± 0.62 for Climate Change-Health Perception, and 3.51 ± 0.61 for Climate Change-Health Nursing Practice. Climate Change-Health Nursing Practice was significantly correlated with both EHL (r = 0.52, p < 0.001) and Climate Change-Health Perception (r = 0.53, p < 0.001). Multiple regression identified Climate Change-Health Perception (β = 0.33, p < 0.001) and EHL (β = 0.30, p = 0.001) as significant predictors of Climate Change-Health Nursing Practice, jointly explaining 32% of the variance (F = 34.95, p < 0.001).

CONCLUSIONS: Climate Change-Health Perception and Environmental Health Literacy are key determinants of climate-health nursing practice among Korean Community Health Practitioners serving medically underserved areas. Educational programs targeting both constructs may strengthen the climate-health practice readiness of primary care nurses and enhance the health resilience of rural and medically underserved populations.

This study provides empirical justification for developing integrated Climate Change-Health Perception + Environmental Health Literacy training programs for primary care nursing personnel in medically underserved areas. Linking such programs with public health centers, civil servant continuing education, and nurse refresher education systems is recommended.

Identifying thermally tolerant bull kelp (Nereocystis luetkeana) source populations for restoration under climate change.

Journal of phycology [Epub ahead of print].

Kelp forests are declining in many parts of the world due to climate change and other stressors. Restoration is one solution to return kelp forests to places where they have been lost, yet continually warming oceans may necessitate the identification of thermally tolerant strains to facilitate the long-term success of kelp restoration. The Salish Sea is a waterway in British Columbia, Canada, and Washington State, United States, where ocean temperatures increasingly exceed the thermal limit for bull kelp (Nereocystis luetkeana), causing substantial losses along parts of its range. To identify thermally tolerant source material, we cultured bull kelp sourced from five populations along a thermal gradient in the northern Salish Sea and outplanted them in a common garden experiment at a warm site where bull kelp has been extirpated: Maude Reef on Hornby Island. We tracked stipe length, blade elongation, blade condition, sorus formation, and persistence. Kelp from the nearest cool site reached the largest sizes overall and produced the most sori. In the warm summer, kelp from the nearest warm site had significantly greater blade elongation rates and persisted longer than kelp from distant sites. Blade opacity did not show any distinct pattern, suggesting that loss of photosynthetic pigmentation is likely not the mechanism or consequence of observed differences in growth rate. Significant population-level variation in growth and blade condition may hint at possible adaptive strategies for heat avoidance in bull kelp. From these findings, we suggest population sourcing or mixture strategies that may increase restoration success.

Predicted Global Redistribution of Pyrophilous Beetle Melanophila acuminata (Coleoptera: Buprestidae) Under Climate Change.

Ecology and evolution, 16(9):e74317.

The pyrophilous beetle Melanophila acuminata is a decomposer of freshly burned wood, playing a critical role in nutrient cycling within forest ecosystems. To investigate the impact of climate change on the global distribution of M. acuminata, this study employed MaxEnt modeling in conjunction with 22 environmental variables under current and future conditions (2050s and 2070s) to conduct a comparative analysis of its suitable habitats. After rational screening, a total of 795 global occurrence records and 10 selected key environmental variables were incorporated into the MaxEnt model, which demonstrated excellent predictive accuracy (AUC ≥ 0.919). The results indicate that the mean temperature of the coldest quarter (Bio11) and the precipitation of the driest month (Bio14) are the primary factors limiting the distribution of M. acuminata. Under current climate conditions, its high-suitability areas are concentrated in Northern Europe and the border region between the United States and Canada. Under the high-emission scenario (SSP5-8.5) in the 2070s, the high-suitability area is projected to contract by nearly 36%, with the centroid shifting northwestward to higher elevation and an increase in habitat fragmentation. This projected contraction and fragmentation of suitable habitats may pose particular challenges for M. acuminata, given its known reliance on habitat connectivity for locating fire sites via its specialized infrared sensory system (Schmitz and Bousack 2012). However, direct validation of this mechanistic link requires further empirical investigation. Based on the predicted suitable habitats of M. acuminata in 2050s and 2070s, future conservation efforts should focus on high-suitability areas in Northern Europe and Canada.

Cultural Competency in Sustainable Dermatology: Climate Change, Environmental Impact, and Traditional Care.

Indian journal of dermatology, 71(5):392-394.

Climate change and environmental degradation profoundly affect skin health, necessitating sustainable dermatological practices. Integrating cultural competency enhances these efforts by respecting traditional care systems while promoting eco-conscious choices. Many Indian communities use plant-based, biodegradable, and locally sourced ingredients such as coconut oil, Shikakai, soapnut, hibiscus, and henna, aligning naturally with sustainability goals. Evaluating the life-cycle impact of dermatologic products, reducing plastic use, and incorporating cultural practices like sari or turban-based sun protection can advance equitable and green dermatology. Combining scientific evidence with traditional wisdom fosters inclusive, ethical, and environmentally responsible skin care for a resilient dermatological future.

Climate change, pharmaceuticals and prescribing patterns: a scoping review and proposal for the MAMS model for healthcare educators.

Frontiers in public health, 14:1806075.

BACKGROUND: Healthcare contributes substantially to climate change, and pharmaceuticals account for a meaningful share of this footprint across manufacturing, distribution, prescribing, and disposal. However, climate-health education and prescribing practices are often addressed separately, leaving limited guidance for integrating climate change, pharmaceuticals, and prescribing patterns within a single framework. This scoping review synthesizes evidence on the intersection of these domains, with attention to how these concepts are incorporated into health professions education (HPE) and clinical practice.

METHODS: A comprehensive literature search strategy of six databases (PubMed, Embase, CINAHL, ERIC, Health Source: Nursing Academic, and Web of Science) identified peer-reviewed studies published between January 1988 and December 2025 in English or Spanish. Eligible studies addressed climate change in relation to pharmaceutical use or prescribing patterns and included an educational or practice-based component; animal studies, studies without interventions, and non-prescribing studies were excluded. Searches were conducted in December 2023 and updated in April 2025. Data were extracted on study characteristics, clinical domain, educational approach, and directional relationships mapped to the MAMS model dyads (Climate ↔ pharmaceuticals; pharmaceuticals ↔ prescribing patterns; climate ↔ prescribing patterns).

RESULTS: From 4,247 citations, 28 studies met inclusion criteria. Studies were conducted across multiple regions, most commonly the United States (n = 6), United Kingdom (n = 5), Australia (n = 5), and Canada (n = 4), with additional single country and multinational collaborations. Clinical domains varied, with the largest representation in anesthesia and perioperative care (n = 8), followed by pharmacy and pharmacology (n = 5), primary care (n = 3), and fewer in other specialties. Studies used single and multi-educational domains, most commonly framework development (n = 16), followed by curricular integration (n = 6). Outcomes included reductions in anesthetic or inhaler related emissions, behavior change, knowledge or awareness, attitudes or satisfaction, and identification of barriers and facilitators. Although individual MAMS dyads were frequently examined, no study operationalized all three domains in an integrated bidirectional tri-dyadic manner.

CONCLUSION: Existing literature on climate-conscious prescribing education is expanding but remains clinically concentrated and largely conceptual, with limited evaluation of instructional strategies. No study operationalized a fully bidirectional, tri-dyadic approach linking climate change, pharmaceuticals, and prescribing patterns, underscoring the need for integrated, outcomes-oriented frameworks to guide HPE and practice change.

Climate Change and Food Allergy: Adaptations and Risks at the Intersection of Environment and Health.

Comprehensive reviews in food science and food safety, 25(5):e70628.

Climate change has emerged as a major global public health challenge, and its impact on allergic diseases, particularly food allergy, has received increasing attention. It enhances allergic exposure risks through multiple pathways, including alterations in the expression of allergenic proteins, shifts in the geographic distribution of allergenic species, increased allergenic microbial pollution, and changes in pollen exposure patterns that may exacerbate allergic responses. Furthermore, climate change could elevate individual susceptibility to food allergy via diverse biological mechanisms, such as impairment of host barrier integrity, disruption of immune tolerance homeostasis, and perturbations in early-life developmental processes. Additionally, climate change-induced loss of microbial and dietary diversity further promotes allergy sensitization, whereas the transition to plant-rich sustainable diets may bring additional allergy risks. This review systematically summarizes these potential mechanisms by which climate change elevates food allergy risks, aiming to provide a basis for food safety risk assessment and the development of scientific, targeted preventive strategies against allergic diseases in the context of ongoing global climate change.

Global and regional climate change impacted Paleogene mammal faunas in Central Asia.

Nature communications, 17(1):.

Global climate change has been linked to faunal turnover throughout geological history, but the effects of regional environmental change remain comparatively less understood. Central Asian environments changed repeatedly throughout the Paleogene (ca. 66 to 23 Ma) due to topographic reshaping and global climate change. Additionally, recently published geological records indicate that intense, regional aridification occurred during the mid-Eocene. We test the signatures of regional versus global climate change events in the fossil record, reconstructing Paleogene sampling-corrected taxonomic richness, faunal turnover, and body size change for all Central Asian mammals. We find three macroevolutionary transitions in mammal assemblages. One associated with regional Asian mid-Eocene aridification and two with global events - the Paleocene-Eocene Thermal Maximum (short-lived extreme warming 56 Ma) and the Eocene-Oligocene Transition (prolonged cooling 34 Ma). Our results indicate that both global and regional climate were associated with mammal evolution in the Paleogene of Asia. We also find that a previously described Eocene/Oligocene transition from Perissodactyla-dominated to Glires-dominated faunas - thought to be associated with cooling at the Eocene-Oligocene Transition - may be a sampling bias artifact.

Climate Change-Mediated Temperature Extremes: Effects on the Immune System and Associations with Immune-Related Diseases.

Clinical reviews in allergy & immunology, 69(1):.

Climate change exacerbates extreme temperature events, which pose a growing global threat to human health, especially disturbing the immune system and increasing the incidence of immune-related diseases. This review synthesizes the multifaceted links between extreme temperatures and human immune system. Extreme temperatures could activate the neuroendocrine system, trigger the release of cytokines, regulate heat shock proteins (HSPs) and induce epigenetic modifications. The epithelial barrier dysfunction and gut microbiota dysbiosis are involved in the association between extreme temperature and immune system. These immune perturbations increase the risk of allergic diseases, autoimmune disorders and infectious diseases, disproportionately affecting children, elderly, patients with chronic diseases and people living in low-income and geographically vulnerable areas. Noting limitations like insufficient focus on vulnerable groups and static models, this review highlights the urgency of addressing climate-temperature-immunity interactions to guide climate-resilient public health strategies.

Invertebrates at the Land-Sea Interface in a Climate Change World: Heatwaves, Floods, Fire and Ice.

Global change biology, 32(9):e71096.

With their location at the land-sea edge, coastal marine invertebrates withstand marked changes in water and air temperatures and abrupt salinity changes through tidal cycles. In a climate-changing world, these stressors are being magnified by the increased intensity and emergence of extreme climatic events (ECEs). Diverse habitat-dependent communities on rocky shores, mudflats, mangroves and saltmarsh are at the forefront of ECEs, which can co-occur and interact with other anthropogenic stressors. This review synthesises information on the vulnerabilities of coastal marine invertebrates living at the interface between marine and terrestrial environments to marine and atmospheric heatwaves, fire, flooding, hyposalinity and changes in intertidal ice cover. The impacts of ECEs on bivalves are investigated as these are ecologically and economically important keystone species. We synthesise impacts of extreme heat stress on these molluscs as a case study. Temperature and salinity extremes are particularly damaging to coastal invertebrate communities if they coincide with low tide cycles. As adaptation to environmental variability is an inherent feature of the evolution in the intertidal, it will be important to understand tolerance levels with respect to ECEs, as this varies between species and across tidal cycles. It is also important to understand the capacity to build climate resilience through acclimatisation, adaptation, plasticity and the presence of refuge habitats, as well as identify the potential for species' redundancy with respect to the provision of key ecosystem services.

Climate change-related weather emergencies, aging and inequalities among racialized older adults: An intersectional climate justice framework informed scoping review.

Journal of aging studies, 78:101439.

As global aging accelerates alongside intensifying climate disruptions, older adults face growing exposure to extreme weather events that threaten their health and well-being. Yet, the experiences of racialized older adults, categorized as those who are non-White or non-Indigenous who often inhabit the intersection of social and ecological shaped by social marginalization, economic disadvantage, and other factors remain insufficiently understood. Guided by an Intersectional Climate Justice lens, this scoping review examined how racialized older adults across diverse contexts experience and respond to climate change-related weather emergencies. Using Arksey and O'Malley's approach, searches across 13 databases yielded 28 studies, most involving community-dwelling older adults. Findings show that racialized older adults face layered vulnerabilities shaped by age-related decline, chronic conditions, low income, limited education, and inadequate housing. These factors, combined with neighborhood disadvantage and environmental exposures, produce profound personal, psychosocial, and health impacts. The review highlights the need for equity-centered climate preparedness grounded in community resilience, care ethics, place-based practices, and meaningful participation of this group in environmental decision-making.

Multi-seasonal modelling of Carica papaya and Paracoccus marginatus interactions under climate change.

Mathematical biosciences and engineering : MBE, 23(8):2516-2580.

The papaya mealybug, Paracoccus marginatus, has emerged as a formidable threat to global tropical agriculture, capable of inducing devastating yield losses through its invasive sap-sucking behavior. While conventional models often overlook environmental complexities, in this study, we introduced a sophisticated multi-seasonal mathematical framework designed to unravel the intricate interplay between mealybug population dynamics, fluctuating climatic conditions, and the persistence of off-season natural reservoirs. Sensitivity analysis highlighted how parameter influences shift across seasons, while our qualitative analysis revealed a dual-threshold mechanism, governed by the local offspring number $ \mathcal{N}_0 $ and the global stability threshold $ \mathcal{N}_g $, as the definitive driver of the system's long-term evolution. While $ \mathcal{N}_0 < 1 $ analytically ensures local asymptotic stability, our theoretical discussion suggested the existence of a conjectured regime of bistability within the threshold range $ \mathcal{N}_g < \mathcal{N}_0 < 1 $. This finding highlighted a critical regime where the success of eradication efforts is strictly contingent upon the initial infestation levels. Furthermore, by employing uniform persistence theory, we proved that the pest inevitably establishes a permanent foothold whenever $ \mathcal{N}_0 > 1 $. To mitigate these agricultural losses, we evaluated the efficacy of two distinct intervention frameworks: (ⅰ) Pulsed biological control via impulsive parasitoid releases and (ⅱ) a synergistic integrated pest management (IPM) strategy combining biopesticides with natural enemies. Our simulations demonstrated that while impulsive parasitoid releases alone achieved substantial suppression, reducing immature and mature female populations by 89.35% and 93.04%, respectively, and recovering 75.92% of papaya production, the integrated approach proved transformative. By synchronizing biopesticide applications with parasitoid pulses, mealybug populations were nearly decimated, with reduction rates reaching 99.70% for immatures and an exhaustive 99.90% for adults. Although this intensive suppression yielded a 44.92% increase in net productivity, its primary value lies in providing a robust, non-linear pathway toward total pest eradication, effectively breaking the cycle of reinfestation.

Knowledge, attitude, and practices regarding climate change and its oral health effects among dental health care providers in India. A cross-sectional study.

Revista cientifica odontologica (Universidad Cientifica del Sur), 14(3):e300.

BACKGROUND: Climate change is increasingly recognized as a major public health threat. Despite its growing relevance, the implications for oral health and the preparedness of future dental professionals remain underexplored. This study assessed dental students' knowledge, attitude, and practices (KAP) regarding climate change and its effects on oral health.

MATERIALS AND METHODS: A cross-sectional study was conducted using a validated self-administered questionnaire comprising 29 closed-ended items across three KAP domains among dental students. Descriptive statistics summarized participant responses, while the Chi-square tests assessed associations between categorical variables, and independent t-tests and one-way ANOVA compared mean KAP scores across groups, with Tukey's HSD for post hoc differences. A p-value < 0.05 was considered statistically significant.

RESULTS: More than half (55.8%) of students demonstrated good knowledge, with CRI students recording the highest mean knowledge score (11.78 ± 1.57). Knowledge scores differed significantly by year of study (p = 0.004). First-year students showed the highest attitude scores (8.52 ± 1.08; p < 0.001); however, 57.6% expressed unfavorable attitudes. Practices were the weakest domain, with only 45.6% exhibiting good climate-conscious behaviors (highest: first-year; 5.62 ± 1.61; lowest: third-year; 2.52 ± 2.07). Gender (p = 0.027) and year of study (p < 0.001) were significantly associated with practice scores. Significant positive correlations were found between KAP (p < 0.01), indicating mutually reinforcing domains.

CONCLUSION: Strengthening curriculum integration and promoting climate-resilient behavior change among future dental professionals are essential to support environmentally responsible oral healthcare, ultimately ensuring quality care for the community.

Nurses' Perceptions and Behaviors Regarding Climate Change and Health: A Correlational Study Aligned With Saudi Vision 2030.

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

Climate change is an escalating threat to population health, placing increasing pressure on healthcare systems. Nurses play a pivotal role in delivering climate-resilient healthcare; however, evidence regarding their perceptions and climate-related health behaviors in Saudi Arabia remains limited. This study examined the relationship between nurses' perceptions of climate change and their climate-related health behaviors in support of the population health objectives of Saudi Vision 2030. A cross-sectional survey was conducted among 307 nurses in Saudi Arabia using the validated Perceptions and Behaviors regarding Climate Change and Health (PBCH) questionnaire, which assessed awareness, concern, and climate-related behaviors in both domestic and clinical settings. Data were analyzed using descriptive statistics, reliability testing, Pearson correlation, Ordinary Least Squares (OLS) regression, and quantile regression to examine predictors across different levels of behavioral engagement. The findings revealed moderate PBCH scores (mean percentage approximately 68%-69%) and excellent internal consistency (Cronbach's α up to 0.96). Awareness and concern demonstrated strong positive correlations with PBCH scores and consistently predicted climate-related health behaviors across OLS and all quantiles (0.25, 0.50, and 0.75), whereas demographic characteristics showed minimal predictive value. These findings suggest that strengthening nurses' awareness of and concern about the health impacts of climate change may significantly enhance sustainable nursing practices, improve population health protection, and support the achievement of Saudi Vision 2030.

Climate change impact on disease emergence and antimicrobial resistance: A perspective on transmission and detection.

iScience, 29(9):116694.

Climate change is increasingly disrupting environmental and ecological systems, creating conditions that facilitate the emergence, transmission, and persistence of infectious diseases and the spread of antimicrobial resistance (AMR). This scoping review analyzed 427 articles published over the past five years, retrieved from major scientific databases. Findings show that climate variables significantly influence pathogen growth, reproduction, and transmission through vectors. Strong associations were identified between climatic changes and the spread of bacterial, viral, fungal, and protozoal diseases. Temperature fluctuations and anoxic conditions can promote AMR development. Climate-driven migration of birds and bats further contributes to cross-border pathogen transmission. The review also highlights emerging AI tools for rapid pathogen detection, diagnosis, and surveillance. Overall, climate change poses significant public health risks through increased infectious and non-infectious disease burden, zoonotic spillover, and AMR spread, emphasizing the need for integrated climate-health policies, AMR stewardship, AI-enabled surveillance, and interdisciplinary One Health research.

The impact of climate change and weather extremes on chestnut and olive crops in Portugal.

Journal of environmental management, 417:130879 pii:S0301-4797(26)02339-X [Epub ahead of print].

Climate change poses a significant risk to agroecosystems, particularly for perennial fruit trees such as chestnut and olive, by affecting phenological processes, physiological stress, and interactions with pests, diseases, and environmental factors. Although previous research has examined the effects of climate change on crop productivity and plant health, important gaps remain in understanding how long-term climate trends and extreme weather events influence yields across different phenological stages. This study evaluates the effects of climatic variability and extremes on the productivity of chestnut and olive trees in Portugal over a 39-year period. Results show that the timing and intensity of climatic events relative to key phenological phases strongly influence productivity patterns in both species. Excessive rainfall during the fruit-ripening stage was associated with reduced chestnut yields, while excess soil moisture during ripening negatively affected olive production in northern Portugal. In contrast, higher average temperatures, particularly during ripening, were linked to increased olive productivity in southern Portugal. Overall, climate impacts were highly stage-specific and differed between species, with significant interannual legacy effects also contributing to productivity variability. These findings highlight the importance of incorporating phenological timing and lagged responses into crop-climate analyses to improve modelling accuracy and support the development of effective adaptation strategies for Mediterranean agroecosystems.

The decrease in ocean heat transport in response to global warming.

Nature climate change, 13(11):1229-1236.

The ocean is taking up additional heat but how this affects ocean circulation and heat transport is unclear. Here, using coupled model intercomparison project phase 5/6 (CMIP5/6) climate projections, we show a future decrease in poleward ocean heat transport (OHT) across all Northern Hemisphere latitudes and south of 10° S. Most notably, the CMIP5/6 multimodel mean reduction in poleward OHT for the Atlantic at 26.5° N and Indo-Pacific at 20° S is 0.093-0.304 PW and 0.097-0.194 PW, respectively, dependent on scenario and CMIP phase. These changes in OHT are driven by decline in overturning circulation dampened by upper ocean warming. In the Southern Ocean, the reduction in poleward OHT at 55° S is 0.071-0.268 PW. The projected changes are stronger in CMIP6, even when corrected for its larger climate sensitivity. This is especially noticable in the Atlantic Ocean for the weaker forcing scenarios (shared socioeconomic pathway SSP 1-2.6/representative concentration pathways RCP 2.6), where the decrease is 2.5 times larger at 26.5° N due to a stronger decline in the Atlantic meridional overturning circulation.

A global assessment of actors and their roles in climate change adaptation.

Nature climate change, 13(11):1250-1257.

An assessment of the global progress in climate change adaptation is urgently needed. Despite a rising awareness that adaptation should involve diverse societal actors and a shared sense of responsibility, little is known about the types of actors, such as state and non-state, and their roles in different types of adaptation responses as well as in different regions. Based on a large n-structured analysis of case studies, we show that, although individuals or households are the most prominent actors implementing adaptation, they are the least involved in institutional responses, particularly in the global south. Governments are most often involved in planning and civil society in coordinating responses. Adaptation of individuals or households is documented especially in rural areas, and governments in urban areas. Overall, understanding of institutional, multi-actor and transformational adaptation is still limited. These findings contribute to debates around 'social contracts' for adaptation, that is, an agreement on the distribution of roles and responsibilities, and inform future adaptation governance.

Process optimization of adsorbent production from waste printed circuit board non-metallic fractions based on climate-change impact and cumulative energy demand.

RSC advances [Epub ahead of print].

The non-metallic fraction (NMF) generated during waste printed circuit board (WPCB) recycling represents a major challenge for electronic-waste management because of its limited recycling opportunities and potential environmental burden. Although NMF can be converted into value-added ion-exchange adsorbents, the environmental implications of adsorbent production remain largely unexplored. To address this knowledge gap, a cradle-to-gate life-cycle assessment was conducted to quantify the climate-change impact (CC) and cumulative energy demand (CED) of ion-exchange adsorbent production from WPCB-derived NMF. Four production routes differing in water consumption and moisture-management strategy were evaluated to identify preferable process configurations and major environmental hotspots. Substantial differences were observed among the evaluated routes. On the basis of 1 kg NMF processed, CC decreased from 33.1 to 5.18 kg CO2-eq, while CED decreased from 737 to 126 MJ across the scenarios. Relative to the baseline configuration, the concentrated-paste route reduced CC and CED by approximately 84% and 83%, respectively. Electricity consumption associated with moisture removal and thermochemical conversion was the dominant contributor to both indicators, whereas potassium hydroxide became increasingly important as electricity-related burdens declined. These findings demonstrate that process-design optimization, particularly improved moisture management, can substantially reduce the CC and CED associated with WPCB-derived NMF valorization.

Mapping the Global Habitat Redistribution of Critically Endangered Commercial Fish Species Under Climate Change.

Global change biology, 32(9):e71077.

Climate change is reshaping marine fish habitats. Yet the future habitats' redistribution of fishes that are both critically endangered (CR) and globally commercially exploited remains poorly understood. Here, we assessed current and future suitable habitats for 24 CR commercial coastal demersal fishes selected on the IUCN Red List. Using ensemble species distribution models (SDMs), we projected habitat suitability under SSP1-2.6 and SSP5-8.5 by the 2100 s, and combined the projections with exclusive economic zones (EEZs), marine protected areas (MPAs), and fishing pressure. Most species were projected to experience net habitat contraction by the 2100 s, with stronger losses under SSP5-8.5 and pronounced declines in tropical and subtropical coastal waters. Across 145 coastal EEZs, projected species richness showed marked spatial heterogeneity, with Asia retaining the highest mean richness and Europe showing a net increase. Low-income and lower-middle-income countries supported substantial current species richness but faced stronger relative declines under SSP5-8.5. Projected habitats of CR commercial fishes intersected MPAs in only 49% of coastal countries, indicating substantial protection gaps. Overall, this study quantitatively delineates climate-driven habitat redistribution patterns of CR commercial fishes, suggesting potential implications for optimizing MPAs networks and advancing transboundary conservation strategies to promote marine biodiversity and sustainable fisheries development.

Recent Increase of Greenhouse Gas Emissions from Cryosphere-Influenced Reservoirs under Climate Change.

Environmental science & technology, 60(34):24101-24112.

Global warming leads to cryosphere degradation, transferring large amounts of terrestrial carbon and nitrogen to reservoirs, which may accelerate the release of greenhouse gases (GHGs) to the atmosphere. However, the spatial dynamics and decadal trends of GHG emissions from these reservoirs remain elusive. Here we compile a comprehensive data set of CO2 (1108 measurements), CH4 (661) and N2O (313) concentrations to estimate that cryosphere-influenced reservoirs emit 56.7 ± 9.3 Tg CO2 eq yr-1 of GHGs. Cryosphere-influenced reservoirs account for less than 10% of the global reservoir area, yet they contribute disproportionately high levels of CO2 and N2O emissions. Between 2000 and 2020, total emissions from cryosphere-influenced reservoirs increased significantly by 0.31 ± 0.11 Tg CO2 eq yr-1, which were mainly caused by climate warming and resultant cryosphere melt and thaw. This study highlights that, in contrast to the declining GHG emission trends observed in other reservoirs worldwide with little cryosphere impacts, emissions from cryosphere-influenced reservoirs are on the rise. This represents a growing and critically underappreciated source of anthropogenic GHGs under climate change.

Climate change reshapes the potential transmission risk of human alveolar and cystic echinococcosis in western China: a projection based on MaxEnt models.

Infectious diseases of poverty, 15(1):.

BACKGROUND: Echinococcosis, a severe zoonotic parasitic disease, imposes a significant health burden in western China, primarily as alveolar (AE) and cystic (CE) forms caused by Echinococcus multilocularis (Em) and E. granulosus sensu lato (Egsl), respectively. Its transmission, tied to a complex host cycle, is strongly influenced by climatic factors. This study aimed to model the ecological niches of these parasites, validate predictions with epidemiological data, and project the impact of climate change on future transmission risk geography.

METHODS: Utilizing location data of 1247 human cases diagnosed in western China from 1981 to 2016, obtained from the National Echinococcosis Control Program, and contemporary climate data, we developed optimized Maximum Entropy (MaxEnt) models. This involved defining an appropriate spatial resolution, screening 19 bioclimatic variables to select key predictors (7 for Em, 6 for Egsl), and identifying optimal model parameters. Model performance was evaluated using the Area Under the Curve (AUC) and AUC of 10% Receiver Operating Characteristic (AUCpROC) curve, and validity was assessed via correlation with county-level incidence. Future habitat suitability was projected for multiple periods (2011-2100) under three climate scenarios (SSP-126, SSP-370, SSP-585) generated by 5 global climate models.

RESULTS: The models demonstrated high predictive accuracy (AUC > 0.92; AUCpROC: 0.084 for Em, 0.070 for Egsl) and a significant positive correlation with incidence (ρ > 0.6, P < 0.0001). Em and Egsl exhibited distinct climatic niches: Em prefers cool, stable climates with moderate summer moisture, while Egsl spreads in areas with dry-cold winters, warm-humid summers, and moderate seasonality. Future projections reveal a spatially heterogeneous reshaping of risk. While overall suitability increases, Em's suitable area is projected to shift toward higher altitudes (e.g., expanding in Qinghai and Xizang but contracting in Ningxia and Gansu). In contrast, Egsl shows widespread outward expansion from current endemic margins, particularly across the Tibetan Plateau. Qinghai and Xizang are identified as key expansion hotspots for both Em and Egsl.

CONCLUSION: The findings confirm distinct ecological drivers for the suitability of Em and Egsl, and indicate that climate change will potentially shift the endemic areas of AE and expand those of CE in western China. This underscores the necessity for forward-looking, spatially targeted surveillance and control strategies, informed by a One Health approach, to mitigate the evolving burden of echinococcosis.

Leaving no one behind in the era of climate change and digitalisation? Barriers to healthy and climate-friendly living among informal caregivers.

Gesundheitswesen (Bundesverband der Arzte des Offentlichen Gesundheitsdienstes (Germany)) [Epub ahead of print].

BACKGROUND: Informal caregivers play a crucial role in supporting older adults, yet they often face challenges that compromise their own health and well-being, particularly in family-based care regimes like Austria. These challenges leave little room for adopting ecologically sustainable behaviours, calling for societal strategies to address climate change without adding pressure. We examined barriers in areas linked to the "triple win" of health promotion, climate mitigation, and social inclusion, and explored the role of Information and Communication Technologies (ICTs).

METHODS: Data were collected in 2024 from a non-probability sample of Austrian caregivers on social contacts, mobility, nutrition, and digital device use. We present descriptive results.

RESULTS: Unpaid caregiving responsibilities reshaped daily routines and challenged health and sustainability (N=204, 81% females; mean age 58±13 years): 15-20% of participants were at risk of social isolation, 54% reported fewer social interactions. Awareness of healthy diets increased partially, but 26% had less time to eat. Mobility patterns showed strong car reliance with higher weekly travel demands (69%). Internet and ICT were used for communication daily (72%).

CONCLUSIONS: Mobility and nutrition offer high co-benefit potential, but structural changes, not individual responsibility, are key. ICT tools should complement in person engagement to leverage positive aspects of caregiving for climate-health co-benefits.

Thermal Stress and Habitat Loss: Assessing the Vulnerability of Potamon fluviatile (Decapoda: Potamidae) to Climate Change in Italy.

Ecology and evolution, 16(9):e74256.

Climate change has the potential to alter the distribution of freshwater species and challenge the effectiveness of existing conservation networks. However, projections of the climatic suitability of Potamon fluviatile under recent climate scenarios are lacking for Italy. In this study, we modeled the potential climatic distribution of the species using an ensemble species distribution modeling approach based on multiple future climate projections. Results indicate that temperature conditions during the dry season are an important predictor of the species' large-scale climatic suitability. Future projections show a contraction of suitable areas, with moderate declines under low-emission scenarios (SSP1-2.6) and substantial reductions exceeding 80% by 2070 under high-emission scenarios (SSP5-8.5). The models show limited expansion into newly suitable areas, although dispersal processes were not represented. Comparing projected suitability with the current protected area network shows that existing conservation boundaries may not cover future suitable areas. While some large protected areas may experience declines in suitability, some smaller coastal reserves may retain stable climatic conditions. It is important to consider that our findings are based on coarse-scale climatic predictors and do not account for hydrological processes or fine-scale habitat characteristics. Our study provides a large-scale assessment of potential climate-driven changes in climatic suitability for P. fluviatile in Italy. Integrating climatic, hydrological, and ecological processes in future models would improve conservation planning for freshwater species.

Development and Validation of PubMed and Ovid MEDLINE Search Filters for Exposure Pathways Linking Climate Change With Public Health.

Cochrane evidence synthesis and methods, 4(5):e70105.

INTRODUCTION: Climate change has major health impacts to which researchers and policymakers need to respond. The volume and multidisciplinary nature of climate-health evidence pose challenges to its comprehensive identification. Search filters are currently not available for this topic. Our aim was to empirically develop sensitivity-maximizing climate-health search filters for two interfaces of the MEDLINE database.

METHODS: Climate change impacts health via several exposure pathways involving distinct mechanisms: extreme weather events, heat stress, air quality, water quality and quantity, food supply and safety, vector distribution and ecology, and social factors. Using the relative recall method, we established a gold standard by extracting included studies of 110 evidence syntheses and classifying them into exposure pathways. From this set, we empirically derived and validated filters per pathway.

RESULTS: Based on 1572 primary studies indexed in PubMed, we developed filters with a sensitivity of 95%, 97% and 99% for six of the seven major climate-health exposure pathways.

CONCLUSION: We designed the first empirically derived search filters for climate-health pathways, enabling sensitive retrieval despite acknowledged limitations. Our filters can be applied to different types of research questions at the intersection of climate and health.

Understanding the Mental Health Impacts of Climate Change in South Africa: Qualitative Insights From Researchers, Practitioners, Ethicists, and Funders on the Need for a Transdisciplinary Approach.

Health science reports, 9(9):e73111.

BACKGROUND: Against a backdrop of entrenched structural inequalities, poverty, and limited healthcare resources, climate change represents a major public health challenge in South Africa, with significant yet under-recognized consequences for mental health. Expert perspectives on these impacts remain limited, highlighting a critical gap in informing transdisciplinary responses.

OBJECTIVES: To explore stakeholder perspectives (researchers/academics, research ethics committee members, employees of organization that funds climate or health research) on transdisciplinary responses to the mental health impacts of climate change in South Africa.

METHODS: This exploratory qualitative study examined expert perspectives on the mental health impacts of climate change. Twelve purposively sampled stakeholders participated in in-depth semi-structured interviews. Data collection continued until data saturation was reached (n = 12). Data were analyzed using an inductive thematic approach.

FINDINGS: Three overarching themes were identified. First, direct mental health impacts included anxiety, depression, trauma, and exacerbation of pre-existing conditions, with links to severe mental illness, including climate-related delusional symptoms and increased substance use. Second, indirect pathways included socioeconomic vulnerability, community resilience, and the dual role of media in raising awareness and contributing to psychological distress. Third, participants emphasized the need for strengthened transdisciplinary approaches.

CONCLUSIONS: Addressing mental health impacts of climate change requires integrated, contextually relevant, transdisciplinary interventions to strengthen resilience among vulnerable communities.

Thermal performance curves and age-stage, two-sex life table of Dermatophagoides farinae (Acari: Pyroglyphidae): baseline data for climate change impact assessment.

Frontiers in insect science, 6:1913734.

INTRODUCTION: House dust mites (HDMs) are major indoor allergens worldwide, with Dermatophagoides farinae being one of the most prevalent species. Temperature is a key driver of mite development, but the thermal biology of HDMs remains poorly characterized. Despite the medical importance of house dust mites, comprehensive thermal performance data across ecologically relevant temperature ranges remain limited, particularly for upper thermal thresholds that will become increasingly relevant under climate warming.

METHODS: We evaluated the development, survival, and fecundity of D. farinae under five constant temperatures (15, 20, 25, 30, and 35°C) at 75 ± 5% relative humidity using the age-stage, two-sex life table framework.

RESULTS: Developmental duration decreased significantly from 15 to 30°C but increased at 35°C due to thermal inhibition. The shortest pre-adult development time was 19.14 days at 30°C, while the longest was 68.98 days at 15°C. Egg-to-adult survival was highest at 25°C (88.6%) and lowest at 35°C (35.7%). The net reproductive rate (R0) peaked at 25°C (33.96 offspring per female), whereas the intrinsic rate of increase (rm) was highest at 30°C (0.0598 day[-1]), reflecting the differential contributions of fecundity versus developmental speed to population performance. D. farinae exhibits optimal development at 25-30°C, with severe thermal stress above 35°C.

DISCUSSION: These baseline thermal performance data provide essential parameters for population models aimed at assessing climate change impacts. Our results suggest that climate warming may initially increase HDM populations in temperate regions but could restrict their distribution in areas where thermal thresholds are exceeded. These findings provide baseline data for assessing allergen exposure risks under future climate scenarios.

Climate change, environmental exposures, and pediatric asthma exacerbations: air pollution, temperature, and relative humidity.

Pediatric research [Epub ahead of print].

The prevalence of pediatric asthma exacerbations (AEs) has risen alongside climate change, yet how climate change modifies these exposures to raise pediatric AEs remains unclear. This review synthesizes epidemiological and mechanistic evidence on the contribution of air pollution, temperature, and relative humidity (RH) to pediatric AEs under climate change, drawing on a narrative search of PubMed and Web of Science (2000-2025) prioritizing systematic reviews, epidemiological studies, and climate-attribution/modeling studies. Climate change intensifies environmental drivers of AEs, to which children's higher ventilation and reactive airways heighten susceptibility. Air pollutants trigger oxidative stress, epithelial injury, and type 2 inflammation, while rising temperatures and extreme weather increase oxidative stress, C-fiber activation, and systemic inflammation. Climate-driven shifts in RH cause airway dehydration at low humidity and impaired mucus clearance at high humidity. Lengthening pollen seasons, transitional-weather viral circulation, and more frequent wildfires, hurricanes, floods, and dust storms further increase exacerbation risk. Climate-driven environmental changes contribute to pediatric AEs, though attribution is quantified for only selected exposures. Prevention strategies, including heat- and air-quality warning systems, environmental adaptation, and equity-focused targeting of high-risk populations, are needed. IMPACT: Climate change amplifies environmental triggers of pediatric asthma exacerbations, a burden concentrated among disadvantaged children by socioeconomic and structural disparities. Children's physiological vulnerability heightens their sensitivity to these triggers. Closing pediatric-specific attribution gaps and integrating climate-adaptation strategies into asthma care could reduce this burden.

Association Between Midwifery Students' Awareness of Global Climate Change and Their Attitudes and Behaviours Toward Medical Waste.

Nursing open, 13(9):e70746.

AIM: This study aimed to determine whether midwifery students' awareness of global climate change is associated with their attitudes and behaviours toward medical waste management.

DESIGN: This study employed a descriptive cross-sectional design.

METHODS: The study was conducted during the 2025-2026 academic year at Atatürk University. The sample consisted of volunteer midwifery students enrolled across all academic years. Data were collected using a sociodemographic questionnaire, the Global Climate Change Awareness Scale and the Medical Waste Attitude and Behaviour Scale. Data were analysed using descriptive statistics, independent samples t-tests, one-way ANOVA with Bonferroni post hoc tests and Pearson correlation analysis.

RESULTS: Participants demonstrated high levels of climate change awareness (74.60 ± 8.21) and generally positive attitudes toward medical waste management (96.91 ± 12.10). Fourth-year students had significantly higher awareness scores than students in lower academic years (p < 0.05). Students who perceived climate change as a professional responsibility and believed that it affected health had significantly higher climate change awareness scores. A moderate positive correlation was identified between climate change awareness and medical waste attitudes (r = 0.392, p < 0.001).

Nurse educators should integrate climate change, environmental sustainability and medical waste management into undergraduate nursing and midwifery curricula using evidence-based educational strategies. Strengthening students' environmental competencies may promote sustainable healthcare practices, improve waste management behaviours and prepare future healthcare professionals to address the environmental challenges associated with climate change.

Climate anxiety moderates the association between perceived direct experiences of climate change & substance use in college students.

Journal of American college health : J of ACH [Epub ahead of print].

Objective: This study sought to understand how climate change anxiety may moderate the association between perceived direct experiences with climate change and substance use behaviors in a college student sample. Participants: Undergraduate students (N = 184) at a private, urban university in the United States Mountain West region. Methods: Students self-reported substance use behaviors, perceived direct experiences with climate change, and climate anxiety. Using multiple linear regression, a composited substance use variable was regressed onto perceived direct experience with climate change, with climate anxiety as a moderator. Results: The interaction between perceived direct experience and climate anxiety was associated with riskier substance use (beta = 0.02, standard error = 0.01, t-value = 2.87, p = .005). Conclusions: Should these findings replicate across contexts, college students who experience climate change impacts and heightened climate anxiety may be susceptible to increased substance use.

The climate change dilemma of ski destinations: adaptation becomes maladaptation.

Frontiers in sports and active living, 8:1865169.

Climate change is progressively eroding the operational viability of ski tourism, while measures intended to sustain winter seasons can generate new vulnerabilities. This study examines how technical interventions, infrastructure reinforcement, and activity-expansion strategies shape adaptation and maladaptation risk in Japan's ski sector. We develop an exploratory Snow Reliability Line (SRL) screening framework that links elevation-based snow-reliability exposure, publicly documented resort actions, and maladaptation coding. The exposure framework is calibrated with Japan Meteorological Agency (JMA) 1991-2020 station climatology and tested through multi-parameter sensitivity analysis. It combines Alpine SRL research with a Japan-oriented regional adjustment and a document-based assessment of adaptation and maladaptation pathways. The maladaptation evaluation relies exclusively on conservative, document-based policy analysis of publicly available resort materials. The exploratory classification reveals a spatial and operational divide. High-elevation and northern resorts retain relatively stable winter conditions, whereas low- to mid-elevation sites are more frequently classified as snowmaking-dependent or critically marginal. Maladaptation risks are concentrated in the A1-B1-Dead and A1-B1-C1 pathways, where activity expansion, extended operations, accessibility incentives, and fixed winter infrastructure are associated with higher aggregate energy demand, opportunity costs, and path dependence. The findings show why ski-destination adaptation should be evaluated together with mitigation, anticipatory governance, investment flexibility, and year-round carbon accounting. Among the 14 resorts in the two highest-risk pathways, six show no documented transition planning, indicating potential continuity-driven maladaptive exposure distinct from action-driven lock-in.

Midwives' Climate Change Awareness, Planetary Health Literacy, and Psychological Preparedness for Climate-Related Maternal and Newborn Risks: A Systematic Review.

International nursing review, 73(3):e70229.

AIM: To synthesise and critically appraise empirical evidence on midwives' climate change awareness and planetary health literacy, the psychological attributes underpinning their readiness for climate-related maternal and newborn risks, the educational interventions targeting these attributes, and the systemic factors shaping their preparedness.

BACKGROUND: Climate change threatens maternal and newborn health through extreme heat, flooding, and disruption of services. Midwives are well positioned to deliver climate-responsive care, yet the constructs used to describe their preparedness-awareness, literacy, resilience, and readiness-are inconsistently defined and measured, and no prior systematic review has synthesised and appraised this evidence with explicit attention to what individual studies actually assessed.

METHODS: A systematic review was conducted according to PRISMA 2020 and registered with PROSPERO (CRD420251135183). Six databases (PubMed/MEDLINE, Embase, Web of Science, Scopus, PsycINFO, and CINAHL) were searched for primary empirical studies published between January 2000 and July 2025 involving practising midwives, student midwives, or midwifery academics. The Capability-Opportunity-Motivation-Behaviour (COM-B) model guided the synthesis. Constructs and instruments were extracted exactly as reported and mapped transparently to review domains. Risk of bias was assessed with RoB 2 and Joanna Briggs Institute tools.

RESULTS: Six studies met the eligibility criteria: two randomised controlled trials, three qualitative studies, and one consensus study, together involving 333 midwives, student midwives, and midwifery academics in Türkiye, Australia, and the Democratic Republic of the Congo. No study directly measured planetary health literacy with a validated instrument, and none measured psychological readiness as a defined construct; the available evidence comprised proxy indicators, principally climate change awareness, resilience, and perceived stress. Interactive climate change education significantly improved midwifery students' awareness, and resilience-based training improved practising midwives' resilience and reduced stress. Qualitative evidence indicated that midwives recognise climate-related threats to mothers and newborns but respond through improvised strategies in the absence of formal training, protocols, and institutional support. Both trials were rated at low risk of bias; the four non-randomised studies carried some concerns.

CONCLUSION: Direct evidence on midwives' planetary health literacy and psychological readiness does not yet exist. A small, geographically concentrated body of evidence on related proxy constructs suggests that educational and resilience-focused interventions are promising, while systemic supports remain largely absent. Construct-explicit measurement, validated instruments, and system-level preparedness research are priorities.

IMPLICATIONS FOR NURSING: Educators and professional-development providers can draw on validated curricular competency content and two trial-tested pedagogies-interactive climate change education and resilience-based training-while recognising that transfer to clinical practice remains untested.

Policy should prioritise the development and validation of measurement instruments for planetary health literacy and psychological readiness in midwifery, the integration of climate-related competencies into curricula and accreditation, and investment in the institutional protocols and supports whose absence this review consistently identified.

Nonuniform resizing of marine life under climate change.

Proceedings of the National Academy of Sciences of the United States of America, 123(36):e2606099123.

Global warming is often predicted to drive universal declines in animal body size, but empirical evidence remains equivocal. This is particularly true in marine systems, where body size distributions are influenced not only by temperature but also by oxygen and productivity, all of which are expected to be greatly altered in future oceans. Differences in regional climate trajectories and the physiology of marine taxa also suggest that body size responses will not be spatially or ecologically uniform. We address these complexities by projecting future changes in mean body size across species within ocean basins using a database of 23,329 marine mollusc species. We quantify how body size distributions change across energetic gradients and forecast assemblage level shifts of the five major classes of molluscs across all 10 oceanic basins. Under high greenhouse gas emission scenarios, we project a significant decline in body size in 68% of class-basin combinations (34 of 50), with some clades expected to shrink by ~16% in mean length by 2100. However, these responses are not universal but are governed by clade-level differences in dominant ecological and physiological strategies and the geography of climate change. Because biomass scales allometrically with length, these trends can correspond to substantial changes in the mass of the average species, from a 46% decline to a 15% increase depending on clade and region. Such widespread functional disruptions may threaten critical ecosystem services (carbon sequestration, nutrient cycling, and human food provisioning), with implications for global marine ecosystem functioning and services.

Synergistic effects of fertilization and climate change on increasing nitrate loading in China.

Journal of environmental management, 416:130773 pii:S0301-4797(26)02233-4 [Epub ahead of print].

Nitrate-nitrogen losses from terrestrial ecosystems to rivers, driven by human activities and climate change, pose significant threats to water quality in China. However, comprehensive long-term quantification of terrestrial nitrate loading across China and the mechanisms driving it remain unclear. Here, we quantified long-term trends in nitrate loading from 1979 to 2018 using Community Land Model version 5 and evaluated the responses to nitrogen fertilizer inputs and climate change using a random forest model. Our results indicated that nitrate loading increased significantly over the past four decades at a rate of 3.3 × 10[-3] Tg N yr[-2]. This increase was primarily attributable to enhanced nitrate leaching (5.2 × 10[-3] Tg N yr[-2]), despite a concurrent decline in runoff of nitrate (-1.9 × 10[-3] Tg N yr[-2]). Attribution results further revealed a clear pathway divergence: fertilization showed the highest explanatory importance for nitrate runoff (60.8%), whereas precipitation and temperature had greater explanatory importance for nitrate leaching. Nitrogen fertilizer accounted for 38% of total nitrate loading. In contrast, precipitation contributed more to nitrate leaching than nitrogen fertilizer. Moreover, the relative importance of predictors varied substantially among China's seven exorheic basins. Temperature showed the highest importance in southern basins, whereas precipitation ranked highest in the Haihe Basin. The influence of nitrogen fertilizer was greatest in northern agricultural basins. Together, these findings clarify the interplay between anthropogenic nitrogen inputs and region-specific climate sensitivities and highlight the need for tailored, basin-scale nitrogen management strategies.

Climate-sensitive infectious diseases in the context of climate change: Lessons from Brazil's floods, with leptospirosis as an example.

Infectious diseases now pii:S2666-9919(26)00104-1 [Epub ahead of print].

INTRODUCTION: Climate variability and extreme weather events may impact climate-sensitive infectious diseases, one example being leptospirosis. This study provided an updated descriptive and exploratory analysis of leptospirosis in Brazil, focusing not only on temporal and regional patterns, but also on the 2024 floods in Rio Grande do Sul, which lent themselves to interpretation of climate-related health effects.

METHODS: Nationwide surveillance data on reported leptospirosis cases, deaths, and case-fatality rates were analyzed across Brazil's five geographic regions from 2014 to 2025, together with mean annual regional precipitation data. Exploratory correlation analyses were conducted using data from 2014 to 2024. While data from 2025 were included descriptively, the epidemiological dataset was incomplete, rendering corresponding precipitation data unavailable, and these data were excluded from correlation analyses. Additional analyses dealt with the epidemiological situation during the 2024 floods in Rio Grande do Sul.

RESULTS: Between 2014 and 2024, Brazil reported 36,261 leptospirosis cases and 3170 deaths. Nationwide, cases increased from 3428 in 2023 to 4142 in 2024, and deaths from 290 to 362. The southern region showed the largest increase, from 1238 to 1988. During the 2024 floods in Rio Grande do Sul, 242 confirmed cases, 17 deaths, and 3270 suspected cases were reported. Even though exploratory analyses identified positive correlations between annual precipitation and leptospirosis cases and deaths in the South and nationwide, their associations were heterogeneous.

CONCLUSIONS: As they illustrate the complexity of assessing climate-related health effects in cases of leptospirosis, these findings should not be interpreted as evidence of causality. Integrated epidemiological, climatic, environmental, and socioeconomic surveillance is essential to the development of climate-informed preparedness and of timely responses to climate-sensitive infectious diseases.

Impact of Anthropogenic Activities and Climate Change on the Wetlands in the North-West of Madagascar.

Plant-environment interactions (Hoboken, N.J.), 7(5):e70206.

Macrophytes are vulnerable to various factors in their natural ecosystems, including climatic, ecological, and anthropogenic changes. This study aims to document how these factors influence floristic composition. Four sites were investigated in the Boeny Region of northwest Madagascar: Ambatoboeny, Marovoay, Ankarafantsika National Park, and Mahajanga II. Floristic inventories were compiled with geographic and floristic parameters, utilizing 1 × 1 m[2] quadrat for each sample. Diversity indices, Analysis of variance (ANOVA), distance based-Redundancy Analysis (db-RDA) were conducted to analyze the data. A total of 98 species were recorded across the four study sites, belonging to 73 genera and 33 families. Twelve species were unique to Mahajanga II, 18 to Marovoy, 16 to Ankarafantsika, and five to Ambatoboeny. Rarefaction curves indicated a progressive trend in species diversity, which appeared to stabilize in both Shannon diversity. The db-RDA revealed species dispersion along longitudinal and latitudinal axes and in relation to vegetation cover. The Permutational Multivariate Analysis of variance (PERMANOVA) indicated a significant influence among the study sites. Over the course of two decades, we observed an increase in temperature at the three districts including the study sites, while precipitation levels progressively decreased during the same period. Wetlands in the northwestern part of Madagascar are in need of conservation and would benefit from further research.

Eco-Anxiety in Latin American Citizens: Description and Factors Associated With Concern About Climate Change.

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

BACKGROUND: Climate change is an undeniable reality that is increasingly discussed globally. While eco-anxiety has been extensively studied in Europe and other developed countries, there is a lack of data from Latin America.

AIMS: To identify and describe the factors associated with eco-anxiety in Latin America.

METHOD: A cross-sectional, multicenter study used a validated scale to measure eco-anxiety, adjusted for sex, age, education level, and country of residence. Descriptive and analytical statistics were employed to interpret the data. Among 3,320 participants, a significant portion expressed eco-anxiety, particularly when it was mentioned to affect an important place, interfere with concentration, disrupt work or studies, or cause difficulty sleeping (12%, 5%, 3%, and 3% strongly agreed with these statements, respectively).

RESULTS: Multivariate analysis revealed higher scores of eco-anxiety in Argentina (aRP: 2.06; 95% CI [1.45, 2.94]; p < 0.001), Colombia (aRP: 1.66; 95% CI [1.21, 2.29]; p = 0.002), and Ecuador (aRP: 1.40; 95% CI [1.01, 1.94]; p = 0.042). Conversely, eco-anxiety was lower among men (aRP: 0.88; 95% CI [0.81, 0.96]; p = 0.003) and those with postgraduate education (aRP: 0.72; 95% CI [0.59, 0.88]; p = 0.001), after adjusting for age.

CONCLUSIONS: This is the first large-scale study to report significant eco-anxiety in Latin America, which is linked to factors such as country of residence, sex, and educational level.

[Response of Vegetation Spatiotemporal Evolution to Climate Change and Human Activities in Gansu Province from 2001 to 2021].

Huan jing ke xue= Huanjing kexue, 47(8):5065-5075.

Located in the transitional zone of three major natural regions in China, Gansu Province serves as a critical area for investigating vegetation dynamics in response to climate change and human activities, providing a scientific basis for regional vegetation conservation and ecological engineering policies. Based on normalized difference vegetation index (NDVI) data and influencing factors datasets from 2001 to 2021, this study employed Theil-Sen Median trend analysis, partial correlation analysis, spatial autocorrelation analysis, and residual analysis to systematically analyze the spatiotemporal variations of vegetation NDVI and their driving mechanisms in Gansu Province. The results indicate that: ① The mean NDVI value during the study period was 0.352, exhibiting a distinct "high in the southeast, low in the northwest" spatial pattern. Both the entire province and individual geomorphic units showed significant upward trends, with 74.25% of the area experiencing vegetation improvement, particularly pronounced in the Loess Plateau of Longzhong and the southern mountainous regions. ② Climatic factor analysis revealed that temperature and precipitation exerted positive effects on vegetation NDVI in over 66% of the study area, with precipitation demonstrating a stronger influence than temperature. ③ Human activities predominantly enhanced vegetation NDVI, with stable grassland and cropland areas contributing the most (cumulatively 60%). The change rates of nighttime light (NTL) and NDVI exhibited a weak positive spatial correlation, displaying "low-low" clustering in the Gannan Plateau, Hexi Corridor, Qilian Mountains, and Beishan Mountains, while "low-high" clustering characterized the southern mountainous area of Gansu and the Loess Plateau in central Gansu. ④ Contribution analysis highlighted that human activities (70.61%) had a greater overall impact on vegetation changes than climate change (29.39%), though spatial heterogeneity was evident-the Gannan Plateau was the only geomorphic unit where climate change dominated. These findings elucidate the differential driving mechanisms of vegetation dynamics in transitional zones and offer critical insights for optimizing regional ecological management strategies.

[Spatio-temporal Dynamics of Vegetation Net Primary Productivity and Its Response to Climate Change and Human Activities on the Xinjiang].

Huan jing ke xue= Huanjing kexue, 47(8):5076-5085.

Amid rapid global changes, understanding how vegetation productivity responds to climate change and human activities has attracted considerable scientific interest. However, research focusing on arid and ecologically fragile regions remains limited. Advancing studies in this area is important for a deeper understanding of carbon source-sink dynamics in arid ecosystems. Xinjiang, as one of China's typical arid and ecologically fragile regions, is also an area with significant changes in vegetation productivity. Using long-term (2001-2022) MODIS net primary productivity (NPP) data, this study applied Theil-Sen Median trend estimation, Mann-Kendall test, stability analysis, and residual analysis to assess vegetation NPP trends in Xinjiang and their responses to climate change and human activity. The validity of the residual method was further evaluated via partial correlation analysis. The results showed that from 2001 to 2022, vegetation NPP in Xinjiang (expressed in C) exhibited a significant increasing trend at a rate of 0.84 g·(m[2]·a)[-1] (P<0.05). Approximately 33.4% of the vegetated area exhibited significant increases, primarily located around oases in the Tarim Basin, as well as the Tianshan and Altai Mountains. The primary drivers of increased NPP in Xinjiang were either human activities alone or their combined effects with climate change. The impact of climate change on NPP growth was relatively minor, contributing less than 20% in areas covering 52.34% of the vegetated region. In contrast, in 72.6% of vegetated regions in Xinjiang, human activities contributed more than 60% to the NPP increase. Partial correlation results indicated that the residual method was effective in isolating the influence of anthropogenic activities. The findings highlight the significant role of human activities in enhancing vegetation productivity in Xinjiang and comparable arid ecosystems.

Accelerated climate-induced risks of nitrogen-loss from agricultural catchments: Empirical modelling of extreme weather events using climate change scenarios.

Water research, 308(Pt A):126728 pii:S0043-1354(26)01402-8 [Epub ahead of print].

Nitrate pollution from agriculture imposes a major threat to global aquatic ecosystems globally, and its impacts are expected to intensify as climate change alters weather patterns, catchment hydrology, and soil processes. Understanding the timing and extent of extreme-weather-events and their impacts on nutrient losses is essential in developing climate-smart adaptation/mitigation measures, in order to avoid further increases in nitrate pollution in receiving water bodies. This study applies an empirical modelling (EM) approach to 15 years (2010-2024) of high-temporal resolution weather and water quality data from six hydrologically-diverse agricultural catchments in Ireland to i)identify climatic conditions associated with increased Nitrogen (N) losses (expressed as NO3N), and ii) estimate the future occurrence of similar N-loss events using climate change projections under different emissions scenarios. Climate projections were derived from an ensemble of models forced by two greenhouse gas concentration pathways: RCP 4.5 (moderate emissions) and RCP 8.5 (high emissions), for three future time periods. Results show a significant increase in both the duration of warm/dry periods, and the annual frequency and intensity of wet/very wet days, particularly under RCP8.5 by the end of the century. The EM identified key temperature and precipitation indices triggering N losses: average air temperature>15°C over 5 consecutive days explained up to 53% of observed N loss events, while effective rainfall (ER) exceeding five mm in one day, and on the preceding day were associated with up to 67% and 77% of loss events, respectively. Future projections indicate large increases in the frequency of conditions associated with N loss, with temperature and precipitation related triggering events projected to reach 17 to 122 and 17 to 79 events per year, respectively, under RCP 8.5 toward the end of the century. Catchment sensitivity was found to depend on catchment characteristics (i.e. drainage status, soil chemistry, farming practices, etc). These findings highlight the need to explicitly account for climate change when addressing agricultural nutrient losses and water quality, meaning that effective adaptation and mitigation measures must be climate-resilient and tailored to specific catchment typologies.

Global Warming Reshapes Bird Distributions and Conservation Priorities in Madagascar.

Environmental research pii:S0013-9351(26)01883-9 [Epub ahead of print].

Anthropogenic climate change is worsening its effects on human societies, economies, natural systems, and biological diversity through altered precipitation patterns and increased global temperatures. Tropical islands and areas with high endemism are especially vulnerable, because rising temperatures and changing rainfall are expected to make vast regions unsuitable for many of their narrow-ranged, endemic species potentially causing the disappearance of bird communities. By combining ecological niche models (ENMs) with community-ecology measures of biodiversity, we assess how the geographic distributions of Madagascar's birds may shift and how a changing climate could reshape their assemblages. We modelled the current and projected future distributions of 237 bird species using conventional ecological niche models for common species and ensembles of small models for rare species, projected under six general circulation models and two emissions scenarios across two future time periods, and linked these projections to assemblage-level measures of species richness, spatial beta-diversity, and community body mass. Our projections point to widespread habitat loss: even under the most optimistic assumptions, almost every species is expected to undergo range contraction, with the majority losing more than half of their current extent. Projected ranges contract by an average of 30.7% under SSP245 and 39.9% under SSP585 across two future time horizons (2041-2060, hereafter '2060', and 2081-2100, hereafter '2100'), with the steepest losses occurring by 2100 under SSP585. While no species is projected to loss its full range worldwide, within Madagascar total habitat loss could cause regional extirpation of 15-27 species by 2060 and 45-237 by 2100, depending on the emissions pathway. These contractions translate into species-richness declines in 62% of assemblages and biotic homogenization in 60% of them, with the heaviest losses concentrated in the central highlands and west and species gains largely confined to the eastern coast. Functional change followed a distinct trend: mean community body size is expected to rise in most assemblages (87.7%), regardless of compositional turnover or elevation. Although individual species respond differently depending on their dispersal ability, behaviour, and energetic demands, our results suggest that climate change may push Madagascar's bird communities toward species loss and biotic homogenization, while simultaneously reshaping the body-size structure of assemblages. Incorporating biodiversity projections of this kind is therefore essential to the success of long-term conservation planning and socio-environmental policy.

Oak masting under climate change: when spatially heterogeneous shifts in flowering phenology reshape pollen limitation.

The New phytologist [Epub ahead of print].

Masting, the irregular, synchronised production of seeds within tree populations, drives forest regeneration and ecosystem dynamics. Its response to climate change may depend on phenological shifts in key reproductive stages, yet this link remains poorly understood. Using 30 yr of daily airborne pollen data from 20 temperate oak populations (Quercus petraea and Q. robur), we examined the relationship between shifts in pollen phenology and pollen limitation (estimated from annual pollen concentration). We analysed how these changes were driven by site-specific weather trends during the forcing and diffusion periods. Pollen phenology advanced overall, while pollen limitation decreased. On average, pollen concentration nearly doubled in 30 yr (+93%) yet with striking contrasts among populations. During the study period, late-flowering populations experienced significant warming during the preseason period, leading to earlier phenology but stable pollen concentration. Conversely, early-flowering populations saw little change in preseason temperatures or phenology but experienced sharp warming during the diffusion period, resulting in a strong increase in pollen concentration. These findings demonstrate that heterogeneous local climate trends induce divergent pollen phenology and pollen limitation trajectories, reshaping reproductive conditions differently among populations. Consequently, oak masting and forest regeneration success may respond differently across populations under continued climate change.

Delivery Riders at the Crossroads of Occupational Health, Climate Change, and Algorithmic Management.

La Clinica terapeutica, 177(5):1238-1241.

Delivery riders have become a defining workforce of contemporary urban economies, yet existing occupational health frameworks remain poorly adapted to the realities of platform-mediated work. This editorial proposes a shift from static, factor-based models of risk toward a dynamic and cumulative perspective, and provides a comparative classification of regulatory approaches worldwide, highlighting how jurisdictions are addressing, or failing to address, the occupational risks of platform work. Riders operate at the intersection of three interacting domains: algorithmic management, environmental exposure, and climate-related stressors. Rather than acting as independent risk factors, these processes mutually reinforce one another, shaping exposure and behaviour in real time. Platform-driven time pressures influence riding practices within hazardous urban environments, while extreme weather and air pollution further affect psychophysiological performance. Within this framework, algorithmic management should be understood not merely as a mode of work organization but as a structural determinant of occupational health. By regulating task allocation, temporal constraints, and incentive structures, digital systems actively generate and redistribute risk. Occupational hazards are therefore not simply encountered by riders but dynamically produced through the interaction between technological control, environmental conditions, and urban infrastructures.

A research agenda for aging and climate change: recommendations from a research-to-practice consensus workshop.

Innovation in aging, 10(9):igag068.

Although climate change poses disproportionate health risks to older adults, studies addressing this critical problem remain scarce and fragmented. As research on the intersection of population aging and climate change effects is increasing, guidance is needed regarding key research priorities for the field. To inform future inquiry, a research-to-practice consensus workshop was convened with 44 multidisciplinary participants, including researchers, practitioners, and policymakers. Using structured small-group discussions and an established priority-setting process, participants critiqued existing research, identified knowledge gaps, and achieved consensus on a research agenda for aging and climate change. Fourteen research priorities included quantifying economic impacts of climate change on older populations, developing evidence-based climate communication strategies, and addressing program access barriers. Additional priorities encompassed healthcare integration, emergency protocols, and disparities research. These findings provide a practice-driven, evidence-informed framework for prioritizing research topics, intervention development, and funding priorities addressing the intersection of aging and climate change.

Nursing education for climate change: historical milestones and pedagogical axes for curricular integration.

Revista brasileira de enfermagem, 79:e20250360 pii:S0034-71672026000100736.

OBJECTIVES: to analyze historical and conceptual milestones that support nursing education for addressing climate change, aligning with Sustainable Development Goals 3, 4, and 13, and to propose pedagogical axes for curricular integration.

METHODS: a qualitative, exploratory, documentary study, grounded in Freire's critical perspective, which problematizes the relationships between global policies and local realities. Data collection took place between September 2024 and March 2025. Thematic analysis was used, guided by the problematization, dialogicity, and transformative praxis principles.

RESULTS: ten documents were analyzed. Five pedagogical axes emerged: historical evolution of the climate-health interface; critical knowledge for facing the climate reality; transformative training in climate and health; recognition and reduction of vulnerabilities; and collaborative and intersectoral action.

FINAL CONSIDERATIONS: the axes provide a foundation for critical and emancipatory nursing education through Freire's methodologies, promoting awareness of socio-environmental determinants of health and capacity building for advocacy in climate justice with vulnerable populations.

Impact of climate change on the irrigation water demand of rainfed crops in the Southern and Steppe regions of Rio Grande do Sul, Brazil.

Anais da Academia Brasileira de Ciencias, 98(3):e20241458 pii:S0001-37652026000307004.

Proper management of natural resources is essential to improve agricultural productivity and reduce potential losses. The PROJETA platform provides global climate models regionalized by the ETA model, enabling more accurate climate projections for specific regions. This study aimed to evaluate the influence of climate change on irrigation water demand using three global climate models (CANESM2, HADGEM2-ES, and MIROC5) regionalized by the ETA model for the baseline period (1961-2005) and two future scenarios (RCP 4.5 and RCP 8.5). The scenarios were subdivided into three future periods and analyzed for 27 municipalities located in the Southern and Steppe regions of Rio Grande do Sul using the SWAP (Soil, Water, Atmosphere and Plant) model. The results indicate variations in irrigation water demand among models and scenarios. Some projections suggest an increase in irrigation requirements in certain municipalities, while others indicate a reduction when compared to the baseline period. The projected increase in water demand is mainly associated with rising temperatures, which may intensify crop transpiration and soil water evaporation. These findings highlight the importance of climate adaptation strategies and improved water resource management to support sustainable agricultural production under future climate conditions.

Rural healthcare providers' attitudes on climate change in the Northwestern US.

Rural and remote health, 26(3):10911.

INTRODUCTION: Climate change is a growing source of concern for rural public health. Despite rural healthcare providers' vital roles in promoting community resilience, their views on climate change and its impacts on their patients' health are not well understood.

METHODS: Using a 38-question online survey, we collected opinion data from rural providers in five states in the Northwestern US, aiming to understand the multifaceted perceptions rural providers have of climate change and its patient-level impacts. Data were aggregated and stratified by variables of interest. Broad trends and effects from demographic variables were modeled using ANOVA analyses and graphical representations, as well as a random forest model.

RESULTS: A total of 115 providers responded to the survey (seven were dropped per exclusion criteria) with comparable populations across several states, age groups, and professions. Nearly all providers believed that climate change is occurring, and most felt that it is impacting patients' health, yet many were unsure of their ability to integrate climate consciousness into clinical practice. Interest in the clinical relevance of climate change was best explained by provider political affiliation and education level. Random forest modeling also suggested effects due to age, tenure, and state of residence, which were masked by confounding factors in the other models.

CONCLUSION: These findings suggest that some providers struggle to make connections between changes in climate and community health outcomes, while others lack the resources and preparation to integrate what they do know into clinical practice. Bridging this gap will likely require institutional investment in continuing education.

Tree-ring δ[13]C and growth responses of Larix principis-rupprechtii to climate change in the Central-Northern Taihang Mountains.

Frontiers in plant science, 17:1896087.

In the context of global warming and aridification, the Taihang Mountains, recognized as a climate-sensitive transitional zone, necessitate a thorough investigation into the adaptive mechanisms of their forest ecosystems. This study investigates the 60-year variations and climate responses of tree-ring stable carbon isotopes (δ[13]C), intrinsic water-use efficiency (iWUE), and basal area increment (BAI) in Larix principis-rupprechtii from the central-northern Taihang Mountains. The results reveal a phased trend in tree-ring δ[13]C, with an increase from 1964 to 2012 followed by a subsequent decline, suggesting dynamic regulation of the ratio of intercellular to atmospheric CO2 concentrations (Ci/Ca) that may be associated with changes in moisture availability after 2012. iWUE increased significantly during the study period, primarily driven by the combined effects of rising atmospheric CO2 concentrations and stomatal regulation. Carbon isotope discrimination (Δ[13]C) exhibited pronounced seasonal responses to climatic factors. Specifically, water availability was the primary determinant of isotopic fractionation during the April-August growing season, while temperature further intensified water stress by increasing evaporative demand. iWUE demonstrated greater sensitivity to climatic variation than BAI. Although their long-term trends showed general consistency, the interannual coupling remained weak. Commonality analysis indicated that Ca and relative humidity explained 89.62% of iWUE variation, whereas iWUE and relative humidity explained only 20.55% of BAI variation, with the independent contribution of iWUE being minimal. These results suggest that persistent water stress limits the effective conversion of increased iWUE into radial growth, potentially counteracting the effects of CO2 fertilization, and that increases in iWUE do not consistently promote tree growth. This study offers essential insights into the future carbon sequestration potential of central-northern Taihang Mountain forests and adaptive management.

Climate Change, Urbanization, and the Emerging Urban Threat of Rift Valley Fever in Tropical and Subtropical Cities: A Narrative Review.

Tropical medicine and infectious disease, 11(8):.

Rift Valley fever (RVF) is a climate-sensitive mosquito-borne zoonosis long regarded as a rural, pastoral disease, yet accelerating tropical urbanization and intensifying climate variability may be reshaping its epidemiology at the urban-peri-urban interface. This narrative review examines how global climate change and urban-specific climatic conditions jointly shape RVF virus (RVFV) vector habitats, transmission, and burden in tropical and subtropical cities, synthesizing 51 of 412 English-language records identified by a structured, non-systematic search of PubMed, Scopus, Web of Science, and Google Scholar (2009-2026) and selected for relevance to urban and peri-urban RVF. This research draws on human, livestock, and vector evidence from Sub-Saharan Africa, the Arabian Peninsula, and Indian Ocean islands across epidemic and inter-epidemic periods. The synthesis indicates that impervious surfaces, poor drainage, and open water storage can recreate the water-retaining function of rural dambos, sustaining a year-round larval habitat, and that Culex quinquefasciatus dominance together with peri-urban cattle may form an amplification bridge to humans. Direct evidence remains scarce, anchored by a single peri-urban serosurvey and limited urban slaughterhouse entomology. Critical gaps include urban primary-vector ecology, infection-rate data, urban-heat effects, city-specific exposure studies, and coupled climate-urban burden models. We conclude that RVF is a plausible emerging urban threat warranting proactive inter-epidemic surveillance and integration of RVF into urban planning and One Health systems.

Widespread "greening paradox" of global forests: Increased greenness but higher climate change risks.

Journal of environmental management, 416:130784 pii:S0301-4797(26)02244-9 [Epub ahead of print].

Global forests have exhibited widespread greening trends over the past two decades, which are commonly recognized as positive signals of ecosystem restoration and enhanced carbon sequestration. However, how climate vulnerability evolved under widespread greening has not yet been assessed for global forests. To address this gap, this study investigated variations of climate change risks along greening gradient for global forests in 2003-2020 by applying the Vegetation Sensitivity Index (VSI) to three satellite-derived LAI products and FLUXNET ground observations. The climate change risk here refers to ecological vulnerability quantified by a composite metric that combines the VSI magnitude and its temporal trend. Our results indicated that more than 70% of global forests experienced greening in 2003-2020. While VSI magnitude generally decreased from tropical to cold-region forests, its temporal trends were positive in cold-region forests and negative in tropical forests, with temperate forests showing small net change. Crucially, we found that climate change risks increased progressively along the greening gradient, highlighting a widespread "greening paradox" in global forests. This paradox was most pronounced in tropical forests. The manifestation of this paradox was primarily associated with temperature and precipitation in tropical forests, with temperature in temperate forests, and with temperature and solar radiation in cold-region forests. Our study identifies a widespread co-occurrence between forest greening and heightened climate change risks, underscoring the need for forests management and adaptation strategies that account for this greening paradox under intensifying climate changes.

Predicting Climate Change Impacts on the Optimal Habitat of Rare Potaninia mongolica Maxim. on the Mongolian Plateau.

Biology, 15(16): pii:biology15161347.

The combined effects of global climate change and human activities are profoundly reshaping the geographic distribution patterns of rare and endangered plants in arid and semi-arid regions, accelerating habitat fragmentation and population decline, thereby posing a core challenge to biodiversity conservation. As a rare semi shrub endemic to the Mongolian Plateau, P. mongolica faces continuous population shrinkage due to habitat fragmentation and climate change caused by extreme weather conditions, overgrazing, and mineral extraction, leaving its survival status critically vulnerable. Based on data from 153 distribution sites, this study employed the MaxEnt model to predict the species' optimal habitat range, analyzed key environmental factors influencing its distribution, and projected that by the 2050s and 2070s, its total suitable habitat will potentially expand northwestward with increased expansion rates as carbon emissions rise. Its distribution is mainly driven by the minimum temperature of the coldest month, the average temperature in the coldest season and precipitation in the warmest season, which conforms to the law of species movement to the northwest caused by climate warming.

Climate Change Reshapes the Habitat Suitability and Niche Stability of Argentina anserina (L.) Rydb. in Three Ethnic Prefectures of Sichuan Province Based on an Ensemble Model.

Biology, 15(16): pii:biology15161357.

Climate change may substantially alter the habitat suitability and spatial stability of highland edible and medicinal plant resources. Argentina anserina (L.) Rydb. is an important wild resource plant in western China, but its potential distribution and future climate-change response in the three ethnic prefectures of Sichuan Province remain insufficiently understood. In this study, we used an ensemble species distribution modeling framework based on 31 spatially filtered occurrence records and 12 environmental predictors to evaluate the current and future habitat suitability of A. anserina under SSP126, SSP370, and SSP585 scenarios for the 2050s and 2090s. The ensemble model showed acceptable overall discrimination ability and was used to identify broad-scale suitability patterns. Mean diurnal range, precipitation of the driest quarter, isothermality, and topsoil pH were the main environmental predictors, indicating that thermal variability, dry-season moisture availability, and edaphic conditions jointly shaped habitat suitability. Under current conditions, the total suitable habitat area was predicted to be 15.57 × 10[4] km[2], accounting for 57.2% of the study region, with high-suitability habitats mainly concentrated in the northern, northwestern, and central areas. Future projections suggested an overall decline in suitable habitats, especially in high-suitability areas, although the magnitude varied among scenarios and periods. Spatial change and centroid migration analyses indicated that future suitable habitats may undergo contraction and westward or northwestward redistribution rather than uniform expansion. Niche overlap analysis further showed moderate to relatively high overlap between current and future environmental spaces, suggesting partial niche stability with scenario-dependent shifts. Given the limited field-based occurrence records, these findings should be interpreted as broad-scale spatial guidance rather than precise local predictions.

Where Can a Threatened Pheasant Persist? Identifying Climate Change Refugia and Mapping Protection Gaps in China.

Animals : an open access journal from MDPI, 16(16): pii:ani16162475.

Climate change and human activities are widely recognized as major drivers of global biodiversity loss. The Brown Eared Pheasant (Crossoptilon mantchuricum), a ground-dwelling avian species unique to China, is confined to a highly fragmented range and faces persistent long-term threats. To devise robust and site-specific preservation strategies, it is imperative to elucidate the species' sensitivity to climate change and pinpoint high-priority protection areas. In this study, we integrated field surveys, ensemble species distribution modelling, Marxan systematic conservation planning, and GAP analysis to assess habitat suitability changes under future climate scenarios and identify conservation gaps for the Brown Eared Pheasant. Our results demonstrate that the species' distribution is primarily driven by annual temperature range, precipitation in the coldest and wettest quarters, and elevation, underscoring its highly restricted climatic niche. Based on current climatic conditions, highly suitable habitats are primarily distributed across specific mountainous regions: Hebei Province (Xiaowutai Mountains), Shanxi Province (the Taihang, Lvliang, and Taiyue mountain systems), Shaanxi Province (Huanglong Mountains), and northwestern Beijing (the Donglingshan area). Simulations conducted across prospective climatic scenarios suggest a continued decline in suitable habitat, which becomes increasingly restricted to higher latitudes and mountainous regions. According to our GAP analysis, current protected area networks fail to encompass 72.27% of the priority conservation zones identified, with significant gaps in the southern Lvliang, Taiyue, and Huanglong Mountains. The outcomes of this research establish a robust empirical foundation with which to inform prospective preservation strategies and habitat stewardship for the Brown Eared Pheasant.

Physiological Effects, Molecular Regulation, and Adaptive Strategies of Heat Stress in Fish Under Global Warming.

Animals : an open access journal from MDPI, 16(16): pii:ani16162573.

Heat stress is one of the most prevalent and unavoidable environmental stressors in modern aquaculture and natural fishery ecosystems. With the intensification of global warming, the frequency, intensity, and duration of extreme heat events have increased substantially, progressively reducing the thermal safety margin of fish. As ectothermic vertebrates, fish rely heavily on ambient water temperature to maintain physiological functions and metabolic homeostasis. Elevated temperatures can induce profound metabolic reprogramming, characterized by suppressed protein deposition, enhanced lipid mobilization, and altered glucose metabolism, while simultaneously causing structural damage and functional dysfunction in critical organs and tissues such as the liver, intestine, gills, and reproductive system. Heat stress also activates the stress axis and oxidative stress responses, often leading to immunosuppression and disruption of antioxidant defenses, ultimately impairing growth performance, behavior, reproduction, and survival. This review focuses on fish and summarizes the major physiological injuries, molecular regulatory pathways, and adaptive strategies associated with heat stress under global warming. Comparative evidence from crustaceans and molluscs is used only where it helps clarify shared or divergent responses among aquatic ectotherms.

Simulation and Prediction of the Potential Distribution of Spodoptera frugiperda Under Current and Three Future Scenarios Based on the Biomod2 Model Under Global Climate Change.

Insects, 17(8): pii:insects17080772.

Spodoptera frugiperda is a highly polyphagous pest that poses a serious threat to global agricultural production. Understanding its species distribution is of great importance under the current context of climate change. In this study, we used the biomod2 platform to integrate six models, namely XGBOOST, Maxnet, Maxent, MARS, GBM, and GLM, to construct an ensemble model. This ensemble model was used to simulate the potential distribution of S. frugiperda under current and three future climate scenarios, and to analyze the main environmental factors influencing its distribution and their change trends. The results indicated that Bio08, Bio16, Bio09, and Bio03 were the major environmental factors affecting the species' distribution. Under the current scenario, the suitable area was approximately 2026.05 × 10[4] km[2], accounting for about 10% of the global land area, and was mainly concentrated in East Asia and central North America. The expansion of S. frugiperda varied among the three future climate scenarios; under the SSP5-8.5 scenario, the expansion toward higher latitudes was the most pronounced, with the total suitable area increasing by 91.8%. Analysis of the three climate scenarios revealed that the expansion trend of S. frugiperda intensified with increasing carbon emissions. Under the most conservative SSP1-2.6 scenario, even a slight reduction in suitable area was possible. This study provides an in-depth exploration of the distribution characteristics of S. frugiperda and its responses to environmental factors from a geographical perspective. These findings contribute to a better understanding of the species' potential distribution and the influence of environmental variables from a spatial standpoint. They offer a scientific basis for the prevention and control of this pest in specific regions, and may also serve as a reference for future studies on similar invasive insect pests.

First Record of Dundubia annandalei Boulard from Bangladesh, with Predictive MaxEnt Modelling of Climate Change-Driven Range Dynamics (Insecta: Hemiptera: Cicadidae).

Insects, 17(8): pii:insects17080788.

This study presents the first record of Dundubia annandalei Boulard in Bangladesh and assesses its potential range dynamics through MaxEnt modeling under current and future climate scenarios (under the 2041-2026, 2061-2080, and 2081-2100 time periods). A total of 63 specimens, collected from various locations during field surveys in February-March 2025, were identified based on morphological characteristics. The species distribution model exhibited excellent predictive performance (AUC = 0.967). Precipitation of the warmest quarter (64.4%), elevation (10.8%), and precipitation of the driest month (9.1%) were identified as the most influential environmental factors. Under current climatic conditions, the suitable area is predicted to cover 861,481 km[2], representing 5.02% of the studied region. Future projections suggest range contraction (SSP585, 2041-2060) and expansion under all chosen emissions scenarios (SSP126 and SSP585), but significant expansion under extreme warming (SSP585), especially during 2061-2080 and 2081-2100. The potential distribution may extend to Bhutan, China, Myanmar, Laos, Nepal, Thailand, Vietnam, Malaysia, Indonesia, and the Philippines. Under climate change scenarios, the results highlight the potential for this species to emerge as a major agricultural concern in the future.

Epidermal growth factor receptor dysregulation and climate change: insights into pollution-promoted lung cancer.

Philosophical transactions of the Royal Society of London. Series B, Biological sciences, 381(1957):.

The global increase of fine particulate matter pollution, intensified by anthropogenic activity, has been increasingly implicated in lung cancer risk, particularly among never-smokers. We discuss how air pollution contributes to respiratory diseases through interactions with the epidermal growth factor receptor (EGFR) signalling pathway. In particular, recent evidence has shown that fine particulate matter promotes lung cancer in cells harbouring a pre-existing EGFR mutation. As such, we also outline how oncogenic mutations in histologically normal tissue may predispose cells to malignant transformations promoted by environmental exposures. Finally, we consider strategies to mitigate the risk of pollution-promoted lung cancer in vulnerable populations and provide future directions for research aimed at precision prevention of lung cancer. This article is part of the discussion meeting issue 'Epidermal growth factor receptor after 40 years'.

Distribution pattern shift and identification of priority conservation areas for three Cyatheaceae species in China under climate change.

Ying yong sheng tai xue bao = The journal of applied ecology, 37(7):2257-2270.

Climate change is profoundly reshaping the distribution patterns of rare and endangered plants and threatening their persistence. We investigated the impact of climate change on rare and endangered Cyatheaceae plants, including Alsophila spinulosa, A. costularis, and Sphaeropteris brunoniana. We used an optimized MaxEnt model to predict their potential suitable habitat patterns and shifts under the baseline period and future periods (2050 and 2090) across three climate scenarios (SSP126, SSP245, SSP585), and identified priority conservation areas through suitable habitat overlap analysis and long-term stable refugia identification. Results showed reliable model predictions (area under the receiver operating characteristic curve>0.96, true skill statistic>0.81, continuous Boyce index>0.90). Climatic factors were the dominant environmental variables driving the distribution of the three Cyatheaceae species. Compared to the baseline period, the suitable habitat area of A. spinulosa continued to shrink under future climate change, while both A. costularis and S. brunoniana showed general expansion in the mid-term (2050) followed by predominant contraction in the late period (2090), with the most significant changes occurring under the high-emission scenario (SSP585). Under the SSP585 scenario, the suitable habitat area of A. spinulosa continuously shrank from 154.22×10[4] km[2] to 97.84×10[4] km[2] by 2090. The suitable habitat area of A. cos-tularis first increased from 138.27×10[4] km[2] to 154.84×10[4] km[2] by 2050, and then declined to 149.44×10[4] km[2] by 2090. The suitable habitat area of S. brunoniana first increased from 92.62×10[4] km[2] to 220.44×10[4] km[2] by 2050, and then declined to 47.68×10[4] km[2] by 2090. The overall distribution patterns of potential suitable habitats for the three Cyatheaceae species under three future climate scenarios were similar to those of the baseline period, concentrated in southwestern and southern China, but all exhibited dynamic change. During the baseline period, the centroids of the suitable habitats of A. spinulosa, A. costularis, and S. brunoniana were located in Liuzhou, Guangxi, Qiandongnan Miao and Dong Autonomous Prefecture, Guizhou, and Zunyi, Guizhou, respectively. The centroids of the three Cyatheaceae species showed an overall trend of northward expansion under low-emission scenario and contraction toward cooler regions to avoid heat under high-emission scenario, with migration intensity increasing with rising emission. In terms of migration direction, A. spinulosa migrated southeastward, A. costularis migrated northwestward, and S. brunoniana migrated southwestward. Southwestern Yunnan (Xishuangbanna, Pu'er, Lincang) and Hainan constitute the core refugia, with the highest and most stable overlap of suitable habitats for all three species, yet there are significant conservation gaps currently. In the future, these regions should be designated as priority conservation areas, with strengthened in-situ conservation in their core refugia, complemented by near-natural habitat restoration to enhance landscape connectivity, thereby addressing the long-term challenges posed by climate change.

ESP Quick Facts

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

Biographical information about many key scientists (e.g., Walter Sutton).
