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.

Assessing climate change impacts on the geographical distribution of Cupressus sempervirens in the Mediterranean region.

Scientific reports, 15(1):40127.

Cupressus sempervirens L., a long-lived conifer of the Cupressaceae family, plays a vital ecological, medicinal, and economic role in the Mediterranean basin. Due to the species' sensitivity to climatic fluctuations, particularly temperature and precipitation regimes, understanding its potential distributional shifts under climate change is critical. This study employs ecological niche modeling to quantify the current and future potential geographic distribution of C. sempervirens under two Shared Socioeconomic Pathways (SSP2-4.5 and SSP5-8.5) for the mid-twenty-first century (2041-2060). Model outputs identified mean diurnal range (bio2), precipitation seasonality (bio15), and annual precipitation (bio12) as key determinants of habitat suitability. Presently, suitable habitats are concentrated throughout the Mediterranean region, with moderate suitability extending into the Euro-Siberian and Irano-Turanian domains. Future climate projections indicated an expansion of climatically suitable areas, most consistently within the Mediterranean basin, where predictions showed higher reliability, whereas additional gains in northern regions (e.g., around the Caspian and Black seas) were associated with greater model uncertainty, reflecting overall increases in suitable habitat of 14.7% under SSP2-4.5 and 16.4% under SSP5-8.5. These findings provide critical insights for developing effective monitoring frameworks and conservation strategies to enhance the resilience and adaptive capacity of C. sempervirens populations amid ongoing climate change.

Exploring Nurses' Perspectives on Climate Change Using Q Methodology.

Nursing research pii:00006199-990000000-00220 [Epub ahead of print].

BACKGROUND: As the negative effects of climate change on health increase, interest in responding to the climate crisis within the health care community is rising. Nurses, who comprise the majority of health care professionals, have significant potential to mitigate the health effects of climate change and can play a key role in addressing this global challenge.

OBJECTIVES: This study aimed to explore nurses' perspectives on climate change and propose strategies to enhance their ability to respond to climate issues based on the results.

METHODS: Q methodology-which combines qualitative and quantitative research methods-was used. Thirty-seven Q statements were selected from 197 statements derived from literature reviews, newspaper articles, books, and interviews. Forty-four nurses in South Korea, who were expected to hold diverse perspectives on climate change, were purposively recruited and participated in Q sorting. The data were collected in July and August 2024 and analyzed using principal component analysis with varimax rotation in PQMethod software.

RESULTS: Four perspectives of climate change were identified among the nurses: being crisis-conscious and solidarity response-oriented, emphasizing the irrelevance to nursing and being corporate response-oriented, recognizing the relevance to nursing and having a strong will to act, and being critically indifferent and passive response-oriented.

DISCUSSION: The findings reveal that nurses' perspectives on climate change can be categorized based on the presence of a professional perspective in viewing the climate issue and the level of climate change response considered desirable. To encourage nurses' active participation in responding to climate change, it is necessary to develop appropriate strategies according to their various perspectives on this issue. The results of this study could be used to formulate solutions that enable nurses to contribute positively to climate change in countries with similar backgrounds to South Korea and those that have achieved rapid economic growth.

Enhanced Microplastic Burial in China's Coastal Blue Carbon Ecosystems: Drivers and Potential Roles in Climate Change Mitigation.

Environmental science & technology [Epub ahead of print].

Blue carbon ecosystems (BCEs) are important hotspots of microplastics. However, the magnitude and drivers of microplastic storage across the coastline, together with their roles in climate change mitigation, remain largely unknown. The results showed that microplastic stocks in the surface 12 cm sediments along the Chinese coast ranged from 2170 to 42,240 particles m[-2], corresponding to 0.01-104.4 kg C ha[-1] of microplastic-derived carbon in BCEs. BCEs enhanced the trapping of microplastics, with 1.3-3.8-fold higher stocks than bare flats, while their contribution to organic carbon stocks was negligible (<1.4%). Assuming that microplastics would be decomposed if not stored in BCEs, we estimated that microplastic burial in BCEs contributes to 0.3-45.3 Gg CO2 eq of avoided emissions across China. Microplastic abundance declined with depth in mangrove sediments, indicating accelerated accumulation in recent decades (R[2] = 0.86), faster than in seagrass or bare flats. Urban area, distance from shore, BCE type, and latitude were identified as the major environmental and human activity factors driving microplastic accumulation in BCEs by a multivariable linear regression model (Microplastic stock = exp(6.20 + 1.13 × Ln(Urban area) - 0.23 × Ln(Distance from shore) + 0.48 × BCEs type - 0.05 × Latitude), R[2] = 0.85). Our study provides new insights into the emerging carbon-pollution interactions in BCEs and offers a scalable modeling approach to inform coastal microplastic management.

Darwin's finches and climate change: insights from a resilient system.

Journal of evolutionary biology pii:8325095 [Epub ahead of print].

Climate change is known to influence biodiversity worldwide, with changes in organismal traits observed in many populations and species. Such effects are not universal, however, with some traits showing remarkable stability through time. Time-series analyses that link environmental variables to trait values can generate useful insights into trait evolution and its ecological bases. We use 24 years of data for beak and body traits in two species of Darwin's finches in the Galápagos Islands, alongside data on temperature and precipitation, to answer three questions: Q1) is climate change present in our study sites? Q2) do time-series of beak and body traits show detectable trends that suggest climate change effects? and Q3) to what extent does weather influence annual variation in beak and body traits? We found that temperature and precipitation have been increasing over the past two decades - although this trend is minor in comparison to year-to-year variation. We next found that time-series of beak and body traits showed no detectable signs of climate change impact, instead they behave either as random walks or stable trajectories. Finally, for both species, analyses for short-term responses show that precipitation has a lagged, negative correlation with beak and body traits (effect size: maximum -0.632, minimum -0.131). Increased precipitation followed smaller traits in subsequent years. Associations of finch traits with temperature were more variable. We discuss reasons why Darwin's finches react to short-term weather changes but not to long-term climatic trends, and how these results relate to other findings in other tropical systems.

The influence of climate change on growth of Arctic charr (Salvelinus alpinus).

Environmental biology of fishes, 108(12):2087-2104.

The Arctic is warming at an unprecedented rate and with longer growing seasons, greater rainfall, and less snowfall. Cold-adapted ectotherms, such as the Arctic charr, Salvelinus alpinus (Linnaeus 1758), are likely to experience changes to growth as a result. Anadromous Arctic charr (charr, hereafter) are of great importance for northern communities, providing a source of income from commercial fisheries and food security from subsistence harvest. Initially, warming is expected to increase the growth of charr, benefitting subsistence and commercial fisheries in the short term. However, over longer time scales, temperatures exceeding the optimum for growth will likely result in metabolic stress, slowed growth, and higher mortality. Thus, the long-term consequences of climate change will likely be negative. We assessed anadromous charr growth from 1984 to 2013 in three stocks around Cumberland Sound using otolith measurements as proxies for age-specific growth. Trend analyses indicated growth had increased in pre-migratory ages over the years. We used mixed models to investigate changes to growth for ages 1-10 in relation to climate variables, finding that growing degree days had the greatest positive influence on ages 1-6 while annual precipitation had an overall negative effect on growth in ages 1-2 and 6-10. Contrary to previous assessments on these stocks, our results suggest charr have indeed experienced changes to growth with climate change. These findings emphasize the need for more thorough long-term growth studies in the management of fisheries as altered growth will affect food security and the economy across the Canadian Arctic.

HEXACO personality dimensions as predictors of environmental attitudes, socio-moral orientations, and climate change beliefs.

iScience, 28(11):113753 pii:S2589-0042(25)02014-0.

In this article, we investigate which personality dimensions provide a common psychological basis for environmental measures and socio-moral orientations (e.g., feeling connected to others, perceiving the environmental problem as moral). In a cross-sectional study (N = 634), we explored the associations between the HEXACO dimensions and a wide range of environmental measures as well as socio-moral orientations related to environmentalism. We found that Openness to Experience was the most prominent predictor of environmental measures, socio-moral orientations, and the belief that climate change is caused by human activity. We further provide a comprehensive overview of how each personality dimension connects socio-moral orientations and environmental measures, highlighting the multifaceted nature of environmentalism. The findings underscore the role of individual differences in coping with the environmental crisis. Our article replicates and extends previous research, contributing to the ongoing discussion on how differences in individual predispositions influence environmental engagement.

Navigating the Nexus of Food Insecurity, Anxiety, and Depression in the Face of Climate Change: A Longitudinal Study in Rural Kenya.

Depression and anxiety, 2025:5510493.

OBJECTIVE: This study aims to address critical gaps in understanding the bidirectional relationships between food insecurity, anxiety, and depression in Meru County, Kenya. By employing a cross-lagged panel analysis, we seek to clarify these temporal dynamics, contributing to the design of targeted interventions that integrate food security and mental health in the context of climate change.

METHODS: A cross-lagged panel analysis was conducted using data from 362 adult participants in a community-based empowerment program (2023) in Meru County, Kenya. Participants completed self-report measures of food insecurity, anxiety, and depression at two time points, 11 weeks apart.

RESULTS: Food insecurity (T1) predicted subsequent anxiety and depression (T2), controlling for within-variable, within-time, and control-variable correlations. Village-level food insecurity (T1) was correlated with significantly higher anxiety (T2). Additionally, anxiety (T1) predicted higher subsequent food insecurity (T2).

CONCLUSION: Food insecurity and anxiety have a complex bidirectional relationship. Interventions that address food security, mental health, and the psychosocial factors that promote adaptation to food-insecure environments are essential for promoting the well-being of individuals and communities in the face of climate change.

Adaptation Strategies to Climate Change: High Andean Plant Species as Ruminant Feed Alternatives.

Animal science journal = Nihon chikusan Gakkaiho, 96(1):e70131.

The understanding and use of plant resources, coupled with the strategic selection of forage species, play crucial roles in biodiversity preservation, enhanced biomass production, nutrient supply, and a reduced ecological footprint. This study aimed to characterize the forage potential of perennial plant species in high Andean ecosystems. Species naturally occurring in livestock production systems were identified and classified based on their botanical and agronomic characteristics. We assessed biomass production, bromatological composition, carbon sequestration, in vitro dry matter digestibility, and methane emissions. Among the 28 identified species, 17 presented optimal characteristics: high biomass, protein (> 7%), gross energy (> 3500 kcal kg[-1]), neutral detergent fiber (NDF), acid detergent fiber (ADF) percentages (< 42% and < 37%, respectively), and in vitro digestibility (> 40%). Plants with relatively high secondary metabolite contents exhibited reduced methane emissions. Carbon uptake varied from 3.27 to 35.41 g C m[-2] or plant. The recognized forage potential of these perennial plant species offers a sustainable option for integration into ruminant feeding systems and silvopastoral practices in the tropical Andes. This strategic integration presents a viable approach for mitigating the impacts of livestock farming in response to climate change.

Thinking climate change through the lens of abstractness: a multi-task and multi-setting investigation into generational differences in the conceptualization of ecology.

Cognitive research: principles and implications, 10(1):79.

To face ecological disasters, one of the major emergencies of modern times, fostering pro-environmental behaviors appears crucial. While research explored various behavioral drivers, few studies addressed the conceptual representation of ecological events at different ages. Our preregistered study fills this gap, examining how different generations conceptualize ecology, considering evidence suggesting a link between climate change abstractness and willingness to act pro-environmentally. Older (> 65 yo) and younger (18-35 yo) individuals performed multiple tasks targeting conceptual processing (categorization), semantic organization (rating), and conceptual representation (feature generation) of ecological (e.g., deforestation) compared to concrete (e.g., spoon) and abstract (e.g., affirmation) concepts. In the categorization task, participants responded to critical ecological, concrete, and abstract words but refrained from responding to animal words. The rating task involved evaluating critical words on semantic aspects (e.g., Abstractness, Familiarity), and the feature generation task listing properties true for each concept. Innovatively, participants were tested in three possible settings (indoor, natural outdoor, urbanized outdoor) to test whether exposure to nature impacts categorization.Results showed that independent from the setting, ecological concepts were similar to abstract concepts, especially in semantic organization and conceptual representation, or more abstractly characterized than them, especially in conceptual processing. Age differences were minimal, but older adults, who showed more positive attitudes toward ecology and nature, characterized ecological concepts more concretely than younger adults.Theoretically, the multifarious characterization of ecological phenomena supports the flexibility of our conceptual system and points to the necessity of overcoming the classical concrete-abstract dichotomy and studying concepts in a more "situated" manner. From a societal point of view, the age-dependent abstractness of ecological concepts might inform policies on how to improve climate change campaigns, tailoring them to different age groups.

Beyond the finite pool of worry: War experiences and climate change concerns in Ukraine.

Ambio [Epub ahead of print].

This study explores the relationship between self-reported war impacts on personal lives and climate change concerns in Ukraine, challenging the "finite pool of worry" hypothesis. Based on survey data, the research reveals that individuals who perceive their lives as critically affected by the war exhibit heightened climate change concerns, suggesting that severe crises can amplify awareness of interconnected global risks. The findings contribute to a broader understanding of risk perception in societies navigating multiple crises and emphasize the importance of environmental considerations in post-conflict dialogue and reconstruction efforts. The study underscores the complex social dynamics of risk perception, advocating for a shift beyond individual psychological explanations toward a more comprehensive understanding of how societies collectively navigate interconnected threats.

Influence of thermal stress on the cellular immunity of Galleria mellonella F. (Lepidoptera: Pyralidae), and the biological traits of Bracon hebetor (Hymenoptera: Braconidae) in a host-parasitoid interaction: implications under climate change.

Journal of insect physiology, 167:104907 pii:S0022-1910(25)00161-1 [Epub ahead of print].

Extreme temperatures, the most evident indicator of climate change, threaten the delicate balance among parasitoids, key components of the ecosystem, and their agricultural pest hosts. Understanding the effects of thermal stress on parasitoids is essential for improving the mass production of Bracon hebetor (Hymenoptera: Braconidae), and predicting how the climate change will affect host-parasitoid relationship. The immune system of the host Galleria mellonella (Lepidoptera: Pyralidae) varied with both temperature and duration of exposure. Total hemocyte count peaked at 40 °C after 24 h due to elevated granulocyte, plasmatocyte, spherulocyte, and other cell types. The mitotic index peaked at 38 °C (24 h) before dropping sharply at 40 °C. Strong encapsulation responses rose significantly at 40 °C compared to 38 °C. Re-exposing adult females of B. hebetor to thermal stress, along with its previously heat-stressed hosts, altered biological traits in both adult females and F1 offspring, especially the reduced egg fecundity. Rising temperatures initially reduced the female sex ratio, but ultimately it nearly balanced out. At 36 °C, 95 % of the 24 eggs per female developed into adults, and prolonged adult longevity increased parasitoid numbers and extended their active period, a key finding. Overall, B. hebetor displayed high thermal tolerance, yet temperature-driven changes in host immunity and parasitoid traits may reshape their interactions under future climates.

Solar potential assessment using machine learning and climate change projections for long-term energy planning.

Scientific reports, 15(1):39935.

This work proposes a novel method for evaluating solar potential, essential for the development, installation, and operation of solar power systems. The approach forecasts solar energy potential for specific sites by utilizing integrated geospatial, meteorological, and infrastructural multidimensional data. A new application has been released to assess the solar capacity globally. The study evaluated various machine learning methods, ultimately selecting an XGBoost model for training on historical sun irradiance and meteorological data spanning from 1980 to 2015. This model demonstrates significant promise for handling complicated nonlinear interactions and simulating temporal weather patterns affecting solar irradiance. Preliminary results indicate a strong capacity for worldwide predictions on the potential of solar energy, utilizing simulated weather data from 2015 to 2099. The application delivers precise solar power estimates and financial viability, enabling rapid and effortless site assessments from any location within minutes. The results demonstrate that the XGBoost model outperforms other ML algorithms, by achieving lower values of RMSE = 0.97 kWh/m[2] and MAE = 0.76 kWh/m[2], respectively, for solar energy potential. Furthermore, to evaluate the impact of the proposed methodology, three case studies were conducted in Mindanao (Philippines), Gobi-Altai (Mongolia), and the Peloponnese (Greece). The results demonstrate the efficacy of the proposed method in long-term solar energy planning.

Coral reefs as ocean-connected ecosystems: Impacts on food webs and reef futures under climate change.

Advances in marine biology, 102:1-31.

Coral reef ecosystems are inherently dependent on their surrounding ocean. Mounting evidence reveals that oceanographic processes deliver pelagic subsidies that shape coral reef food webs and influence reef persistence following disturbance. These findings are challenging the classical view of reefs as 'self-sustaining' ecosystems in oligotrophic seas. Yet our observations of these biophysical interactions are limited, and we lack a fundamental understanding of how ocean-reef interactions structure shallow reef dynamics. As climate change continues to alter fundamental physical processes within our ocean, the impacts of ocean-reef interactions on reef futures remain unknown. In this review, we offer a forward-looking perspective to catalyze our understanding of ocean-reef connections through interdisciplinary studies and more standardized approaches to data collection and validation. We provide a primer for ecologists on some of the foundational physical processes structuring subsurface temperature dynamics and resource supply to coral reef ecosystems and synthesize the available evidence on how these biophysical interactions influence reef food webs, from microbes to sharks and ultimately humans. Lastly, we emphasize how climate change is restructuring vital biophysical processes in the ocean and on reefs and identify practical solutions for improving our ability to more critically evaluate ocean-reef interactions across scales. Achieving this will be crucial to improve our projections of coral reef futures and to help inform strategic management to support and promote reef persistence under climate change.

Differences in climate change impacts on reptile embryos and adults.

Conservation biology : the journal of the Society for Conservation Biology [Epub ahead of print].

Species experience climate change impacts throughout their life cycle; yet, embryos are rarely considered in vulnerability assessments and conservation planning. We conducted a global-scale analysis of developmental traits and climate change effects on embryonic development in 48 oviparous reptiles. We also compared the climate change effects on embryos and adults to identify geographic areas where the 2 life stages are most vulnerable to such effects. In a comparison between adults and embryos in 5 lizard species, we focused on activity restriction and loss of egg development opportunity associated with climate change impacts. Embryos of tropical oviparous reptiles, particularly those in the Amazon, were predicted to be the most vulnerable to climate change. Climate change impacts on embryos were predicted to exacerbate challenges for 13 threatened species, 11 of which were turtles. Areas where embryos and adults were most vulnerable aligned at broad geographic scales (e.g., both concentrated in the tropics). However, for the 5 representative lizard species, conservation priorities based on the effects of climate change on embryos matched poorly with those based on effects on adults. Embryos of tropical oviparous reptiles warrant increased conservation attention, particularly turtles and threatened species. Our results highlight the importance of considering all life stages when assessing species' vulnerability to climate change.

Modeling Current and Future Habitat Suitability for the Snow Leopard (Panthera uncia) Under Climate Change Scenarios in Nepal.

Ecology and evolution, 15(11):e72490.

The snow leopard (Panthera uncia), a Vulnerable apex predator endemic to the mountainous regions of Central and South Asia. It plays a vital role in maintaining the ecological integrity of high-altitude ecosystems. This study modeled the current and future potential habitat distribution of the snow leopard in Nepal using Species Distribution Modeling (SDM). A total of 306 occurrence records were compiled from both primary and secondary sources. Five bioclimatic and four environmental variables were selected to assess their influence on habitat suitability, and the MaxEnt algorithm was used to develop distribution models. Results indicate that nearly one fifth of Nepal's total land area is suitable for snow leopards. Most of these suitable habitats lie within the protected areas (PAs). However, a significant portion of suitable habitat in the western landscapes extends into vulnerable, unprotected regions. Among the environmental variables, annual mean temperature and elevation emerged as the most influential predictors. Habitat suitability was highest in areas with lower temperatures (-5°C to 5°C) and within the elevation range of 4000-4500 masl. Climate projections for mid and late century highlight a substantial concentration of moderately and marginally suitable habitats, with particular severe declines under high emission scenarios. While protected areas were found to provide relatively resilient habitats for the snow leopard, areas outside the PAs network are projected to undergo significant habitat contraction. This emphasizes the urgent need for expanded and adaptive conservation strategies. Notably, this study is the first to quantify the disproportionate vulnerability of habitats outside Nepal's protected area system. In the western region, approximately 42.5% of currently suitable habitat is at risk of severe decline under high-emission scenarios. These findings highlight the limitations of existing conservation paradigms and emphasize the need to extend protections beyond established PAs through the creation of ecological corridors and the integration of climate-resilient conservation planning.

Seasonal coat-colour moulting phenology of snowshoe hares in a Yukon boreal forest undergoing climate change.

Royal Society open science, 12(11):250662.

Climate change is slowly influencing boreal forest ecosystems, with rising temperatures and altered snow conditions driving phenological shifts in many plant and animal species. Using 7 years (2016-2022) of camera trap data from the Kluane Lake region, Yukon, we quantified seasonal moulting phenology and coat-colour mismatch in snowshoe hares. Autumn moult started between 28 September and 3 October and completed between 5 and 11 November, with the mean moult duration ranging from 36 to 43 days. Spring moult initiated between 12 April and 27 April and completed between 16 May and 27 May, with moult duration ranging from 24 to 38 days. Contrary to our expectations, there was no evidence of delayed or advanced moulting phenology over this 7-year period. The mismatch between snowshoe hare coat colour and background showed an increasing trend and average whiteness of the snowshoe hare coat in autumn declined. Temperature and snow variables influenced various aspects of seasonal moulting phenology, in some cases in the opposite direction. Long-term studies utilizing intrinsic and high-resolution microclimatic data and behavioural observations are needed to understand how moulting phenology and mismatch affect predator-prey dynamics and snowshoe hare demography and population dynamics as climate change continues.

Retrospective phenology in western Mediterranean plants: revealing climate change patterns through herbarium specimens.

AoB PLANTS, 17(6):plaf064.

Herbarium specimens have proven useful for assessing phenological responses to climate change. Using preserved specimens, we analysed the changes in day of year (DOY) for four phenophases: three reproductive (preflowering, flowering, fruiting) and one vegetative (growth). We conducted phenological analysis across bioclimatic belts (thermotypes) from the Rivas-Martinez classification and across 77 taxa present in the Baetic Ranges of the southern Iberian Peninsula. Taxa were characteristic, common, or endemic species from Habitats of Community Interest (HCI) under the European Directive 92/43/EEC. Phenological shifts were assessed using two approaches: long-term trends in DOY with time and relationships with historical climate variables related to temperature and precipitation. At the thermotypes level, flowering advanced consistently over time and with increasing temperatures, showing homogeneous responses and suggesting a weakening of altitudinal differentiation. In contrast, growth exhibited thermotype-specific trends, with stronger advances at high elevations, while preflowering and fruiting showed little or no sensitivity to time or climate variables. At the species level, 31% of taxa showed phenological changes over time in the Baetic Ranges (-3.6 days/decade for reproductive and -5.6 days/decade for vegetative phenophases). However, 97% of taxa showed significant relationships with increasing temperatures and decreasing precipitation, particularly with mean annual temperature (-12.7 days for reproductive and -14.3 days for vegetative phenophases per increased °C). These phenological changes could hinder reproductive and vegetative success by causing mismatches with other ecosystem role-players. As the Mediterranean is expected to become warmer and drier, our findings indicate a potential threat to HCI in the southern Mediterranean.

Projected productivity losses and economic costs due to heat stress under climate change scenarios in Brazil.

Scientific reports, 15(1):39775.

Working under extreme heat conditions threatens health and well-being, which is aggravated by climate change. This study estimated the impact of an increase in global temperature on workability in the Brazilian population and its respective economic costs, under two climate change scenarios, projected over the 21st century. Using daytime Wet Bulb Globe Temperature (WBGT) projections from Coupled Model Intercomparison Project (CMIP6) climate models (SSP2-4.5 and SSP5-8.5 scenarios), we estimated productivity losses in the country's principal labour activities: agriculture, civil construction, the manufacturing industry, services, and informal labour. The economic cost was obtained from daily wages, number of workers and productivity loss. Our results indicate that the North, Northeast and Central-West regions face significant increases in daytime WBGT, frequently surpassing 34 °C in the SSP5-8.5 scenario, which may exacerbate the effects of outdoor activities as they are currently carried out. In agriculture and civil construction, productivity could fall by 90%. Daily economic losses for regulated labour activities could reach USD 228 million under SSP2-4.5 and up to USD 353 million in SSP5-8.5. To reduce these impacts, global mitigation action to curb the increase of global temperature must be implemented, while national public policies that protect workers, such as creating cool spaces, providing regular breaks, adjusting working hours and encouraging hydration, must be adopted and reinforced.

OBJECTIVE: Asthma is a chronic respiratory condition characterized by airway inflammation and hyperresponsiveness to internal and external factors. In addition to well-known irritants such as allergens and pollutants, weather conditions-amplified by climate change-are increasingly recognized as contributors to asthma symptoms.

METHOD: This study gives an overview of the literature on Asthma and Climate Change, the Occupational Risks, and Planetary Health Implications.

RESULTS: Environmental changes in temperature extremes and allergen levels can disrupt immune regulation-specifically, the Th1/Th2 balance-thereby contributing to airway narrowing, and stronger inflammatory responses. Climate change worsens respiratory health by prolonging pollen seasons, intensifying allergies, fostering mold and pests, and triggering asthma through extreme weather.

CONCLUSIONS: Given the growing impact of climate change, increasing public and professional awareness is key to safeguarding vulnerable populations and promoting long-term respiratory health.

Food Safety in the Age of Climate Change: The Rising Risk of Pesticide Residues and the Role of Sustainable Adsorbent Technologies.

Foods (Basel, Switzerland), 14(21):.

Climate change is increasingly recognized as a critical factor of food contamination risks, particularly through its influence on pesticide behavior and usage. Rising temperatures, altered precipitation patterns, and the proliferation of crop pests are leading to intensified and extended pesticide application across agricultural systems. These shifts increase the likelihood of elevated pesticide residues in food and water and affect their environmental persistence, mobility, and accumulation within the food chain. At the same time, current regulatory frameworks and risk assessment models often fail to account for the synergistic effects of chronic low-dose exposure to multiple residues under climate-stressed conditions. This review provides a multidisciplinary overview of how climate change intensifies the pesticide residue burden in food, emphasizing emerging toxicological concerns and identifying critical gaps in current mitigation strategies. In particular, it examines sustainable adsorbent technologies, primarily carbon-based materials derived from agro-industrial waste, which offer promising potential for removing pesticide residues from water and food matrices, aligning with a circular economy approach. Beyond their technical performance, the real question is whether such materials and the thinking behind them can be meaningfully integrated into next-generation food safety systems that are capable of responding to a rapidly changing world.

Effect of Climate Change on Food Industry Supply Chain Resilience in China on the Basis of Double Machine Learning Models.

Foods (Basel, Switzerland), 14(21):.

In recent years, global climate fluctuation has been obvious and has had a significant impact on the food industry system, which makes the impact of climate change on the resilience of the food industry supply chain of great concern. Based on this, this paper selects the panel data of 30 provinces in China from 2011 to 2022; it takes the relationship between climate change and the toughness of the food industry supply chain as the entry point, and probes deeply into the intrinsic mechanism of the impact of climate change on the toughness of the food industry supply chain. The study found the following: First, climate change has a significant negative impact on the food industry supply chain resilience, and in climate change, the impact of temperature on the food industry supply chain resilience is significantly higher than the impact of rainfall on the food industry supply chain resilience. Second, the mechanism of the effect of climate change on food industry supply chains exhibits substantial heterogeneity between major food-producing regions and non-major food-producing ones and varies across different levels of mechanization. Third, crop diversification within the study scope remarkably mitigates the negative effect of temperature fluctuations on the resilience of the food industry supply chain. Therefore, the food supply chain system must enhance its capacity to withstand climate change, and current and future resilience should be strengthened by advancing the implementation of adaptation policies, plans, and actions that drive transformation.

Environmental Pawprint of Dogs as a Contributor to Climate Change.

Animals : an open access journal from MDPI, 15(21):.

The environmental impact of companion animals has received little scientific attention compared to that of livestock, even though the global dog population is rapidly increasing, particularly in urban areas. This review addresses the overlooked contribution of dogs to environmental emissions, focusing on feces, urine, packaging waste, and other care-related by-products. The current knowledge from livestock research provides useful analogies for understanding nutrient excretion and gaseous emissions from dog feces, and data on nitrogen and phosphorus inputs highlight their potential to pollute soil and water. We also examine the role of plastic waste from food packaging, waste bags, and accessories, which can degrade into microplastics, and discuss recent developments in biodegradable materials. Evidence shows that owner choices-such as diet composition, protein sources, and product selection-directly affect the environmental pawprint of dogs. Mitigation strategies include optimizing diets to reduce nutrient excretion, applying feed additives developed for livestock, and improving waste management through composting or the use of emission-reducing amendments. In conclusion, dogs should no longer be viewed merely as individual household companions but as a population with a measurable environmental pawprint. Including dogs in emission reporting systems would provide a more accurate basis for mitigation policies and sustainable urban planning.

Climate Change Impacts on Greenhouse Horticulture in the Mediterranean Basin: Challenges and Adaptation Strategies.

Plants (Basel, Switzerland), 14(21):.

Greenhouse horticulture is a cornerstone of year-round vegetable production. However, escalating climate change is intensifying abiotic stressors (i.e., elevated temperatures, increased vapor pressure deficits, water shortage, and modified solar radiation), threatening both crop productivity and postharvest performance. This review synthesizes current knowledge on how these climatic shifts impact greenhouse microclimate, pest and disease patterns, energy and water requirements, as well as crop development in the Mediterranean region. This study focuses on three major crops (tomato, cucumber, and sweet pepper), which prevail in the regional protected cultivation sector. Among the climate-induced stressors examined, elevated temperature emerges as the primary environmental constraint on greenhouse productivity. In reality, however, a combination of climate-induced stressors is at play, acting simultaneously and often synergistically. Among crops, cucumber generally displays the highest sensitivity to climate-induced shifts, whereas sweet pepper tends to be the most resilient. Next, adaptive strategies are explored, including precision irrigation, structural retrofitting measures, renewable energy integration, Decision Support Systems, and climate-resilient cultivars. Regional case studies revealed diverse country-specific counteractive innovations. As key elements of inclusive climate adaptation, supportive policy frameworks and a practical agenda of targeted research priorities are outlined. In conclusion, the sustainability of greenhouse horticulture under a changing climate demands integrated, technology-driven, and region-focused approaches.

Climate Change Projected Effects on Hamatocaulis vernicosus Occurrence in Romania.

Plants (Basel, Switzerland), 14(21):.

Hamatocaulis vernicosus is a pleurocarpous moss of conservation concern, listed in Annex II of the EU Habitats Directive due to its significant and ongoing decline across Europe. H. vernicosus is also listed as 'Vulnerable' on the Red List of Romanian Bryophytes. Despite its protected status, the species remains under-recorded in Romania, where many potentially suitable habitats have yet to be surveyed. The ecosystems, classified as Transition mire and quaking bog (NATURA 2000 code: 7140), are wet peatlands with oligo- to mesotrophic conditions and a pH of 5.0-7.5 H. vernicosus is recorded in 58 Romanian locations (10 confirmed by us, 5 new), spanning the Continental and Alpine bioregions. Models showed good performance (AUC 0.79-0.83; TSS 0.54-0.59), with distribution mainly shaped by mean annual temperature and temperature range, and secondarily by precipitation. The species favors cold, stable climates with high seasonal rainfall. Even though the number of localities reported for this species has increased in recent years, this does not indicate an improvement in its conservation status, but rather is an effect of recent recording efforts. To support targeted conservation planning, an ensemble species distribution model was developed in order to predict the suitable habitats of H. vernicosus across Romania. Both climate models project major range losses for the varnished hook-moss: ~30% by 2050 and ~40-60% by 2100, depending on the scenario. Losses are gradual under SSP245 but more abrupt under SSP585, with increased fragmentation, especially between the Eastern and Southern Carpathians. By integrating field observations with predictive climate change modeling, our study brings critical insights applicable to the conservation of H. vernicosus and the unique peatland ecosystems it relies on.

Influence of climate change on livestock diseases occurrence in Burkina faso, West Africa.

International journal of biometeorology [Epub ahead of print].

Climate change poses a significant threat to livestock production and animal health globally, with particular implications for Burkina Faso. This study explores the links between climate patterns and the resurgence of five major livestock diseases in Burkina Faso, using climatic records from 1961 to 2020 and veterinary clinical data from 2003 to 2019 collected across the Sahel, Sudan-sahel and Sudan climatic zones. The annual and seasonal climate trends were compared over two climatological periods (1961-1990 and 1991-2020) using two independent t-test. It is was found significant changes in rainfall and temperature patterns from one climatological period to the other, with the Sudan zone influenced by maximum annual temperatures, the Sahel zone by minimum annual temperatures, and the Sudan-Sahel zone by both. Poisson regression analysis revealed complex interactions between disease occurrence and climatic factors, with certain diseases like foot-and-mouth disease and Pasteurellosis of small ruminants favoured by warm and humid conditions, while Contagious Bovine Pleuropneumonia was influenced by dry spells. Lumpy skin disease (LSD) manifests in response to cold and wet days. Newcastle disease's occurrence is determined by varying combinations of temperature extremes. These findings underscore the importance of climate change in influencing livestock disease occurrence across different climatic zones in Burkina Faso. They highlight the need for resilient livestock breeding practices, improved management strategies, and climate-smart interventions to mitigate the adverse effects of climate change on animal health and enhance overall agricultural sustainability.

Species distribution modelling of benthic amphipod crustaceans in the deep North Atlantic under climate change.

Scientific reports, 15(1):39581.

Climate-driven changes in environmental factors influence vulnerable North Atlantic deep-sea (> 200 m depth) benthic ecosystems, leading to species range shifts, habitat loss, or extinctions. Amphipod Crustaceans play a crucial role in deep-sea ecosystems, contributing to food web stability and nutrient cycling. However, their large-scale distributions on species level remain poorly understood. In this study, we created species distribution models (SDMs) of 55 North Atlantic deep-sea amphipods in the present day, medium-term (2050-2060) and long-term (2090-2100) future, utilising best, likely, and worst shared socioeconomic pathways (SSPs) scenarios. The results show species-specific responses to climate change. Over half of the amphipod species expand their habitat in some scenarios, while others face habitat loss. Contrasting habitat likeliness is represented by species of the same genera. Additionally, some species experience habitat shifts, particularly northward and towards the Greenlandic coast. Glacial meltwater influx and increased nutrient availability could enhance habitat suitability in certain regions. Poleward shifts are theorised to be temperature-driven. These changes influence biodiversity, food web dynamics, and ecosystem stability. This study provides a baseline for assessing future changes in North Atlantic amphipod distributions. The findings emphasise the need for conservation strategies and taxonomy in predicting ecosystem responses to climate change.

Rice at risk: How double burden of climate change and arsenic threaten food security and human health in vulnerable nations.

The Science of the total environment, 1006:180852 pii:S0048-9697(25)02492-1 [Epub ahead of print].

Rice productivity and grain quality are threatened by the dual challenges of arsenic (As) contamination and climate change. This review explores the impacts of elevated CO2 (eCO2), ozone (eO3) and temperature (eTemp) on As mobilization, speciation and accumulation in paddy soils and rice. Future climate scenarios promote shifts in soil biogeochemistry that enhance microbe-mediated biotransformation of As, such as methylation and thiolation, and increase the mobility of As species. Simultaneously, climate change combined with As toxicity disrupts rice physiology, altering As uptake, translocation and accumulation patterns. Consequently, rice grains show elevated levels of total and inorganic As, coupled with a depletion of essential nutrients such as iron, zinc and key sugar metabolites. Furthermore, As exposure leads to major imbalances in sugar, organic acid, phytosterol and fatty acid metabolites in grains, and causes up to 40 % yield reductions in highly As affected areas. These effects are projected to exacerbate hidden hunger and increase cancer risks across several Asian countries by 2050. Current findings highlight the urgent need for adaptive agronomic practices and the development of climate resilient rice cultivars with low grain As accumulation traits, to safeguard food security and public health in As affected nations and regions.

Foundations of climate change denial: Anti-environmentalism and anti-science.

PloS one, 20(11):e0334544.

Despite a longstanding scientific consensus about the reality of anthropogenic global warming (AGW), a climate change countermovement (CCCM) has worked to undermine and cast doubt on climate science for over three decades. The CCCM is a coalition led by fossil fuel corporations and their advocacy organizations, far-right conservative think tanks (CTTs), conservative foundations and a few dissenting scientists that has successfully thwarted domestic mitigation policies and international agreements aimed at reducing greenhouse gas emissions (GHGs). Social science investigations into the CCCM have become increasingly sophisticated and have provided key insights into the content and influence of AGW denial narratives. Denial narratives reject the basic findings of climate science: the earth is warming (trend denial), largely due to human actions (attribution denial), producing harmful impacts (impact denial), and mitigation policies are ineffective or harmful (policy denial). These narratives cast the integrity of climate science and scientists in doubt; yet a fine-grained analysis of denial narratives has not been conducted. To fill this gap, we analyze the content of 108 books that reject climate science using a two-stage content analysis approach: first, a deductive approach to identify denial claims in the books, and second an inductive approach to analyze the larger semantic ecosystems surrounding the claims. We confirm the major narratives that have been identified in prior research, but discover a consistent, underlying anti-environmentalism along with a rejection of "impact science" that highlights the negative effects of industrial production. These two meta-themes challenge reflexive modernization, which relies on scientific knowledge and global environmentalism to solve environmental problems. This reflects a deep "anti-reflexivity" employed to combat forces promoting the need for major reductions in GHGs and a shift to renewable energy. This anti-reflexive DNA of climate denial serves to protect power and privilege systems formed since industrialization, which has been powered by fossil fuels.

Action potential: Impact of climate change on neurological disease in Ireland.

Irish journal of medical science [Epub ahead of print].

Anthropogenic climate change has led to a significant increase in global average temperatures and the frequency of extreme heat events. Rising temperatures have a broad range of health implications and have the potential to significantly impact neurological disorders and brain health. A growing body of evidence suggests that the incidence and severity of many common neurological conditions (stroke, epilepsy, headache, neuroinflammation, and neurodegenerative disorders) are affected by climate change. Ireland's average temperature is rising, and we are likely to experience extreme heat events more frequently in the coming years. In this review, we highlight the current evidence on the impact of climate change and air pollution on neurological disease in the context of Irish climate trends and advocate for more urgent healthcare planning to address the impact of climate change on the Irish healthcare service.

Health impacts of climate change and role of the health sector in mitigating carbon emissions.

Urologie (Heidelberg, Germany) [Epub ahead of print].

The climate crisis has been identified as the largest threat to human health; paradoxically, the healthcare sector is responsible for 5% of the global greenhouse gas emissions that are driving this crisis. These emissions are largely due to carbon-intensive facilities, energy use, complex global supply chains, transportation and pharmaceuticals. In its role of safeguarding the health of both current and future populations, the healthcare sector must take actions to minimise its environmental impact. Strategies for emission reduction include sustainable infrastructure, clinical practice innovations, and procurement and supply chain reform. This article aims to examine current evidence on the health impacts of climate change and explore strategies through which the healthcare sector can reduce its environmental impact while continuing to deliver high-quality care.

Climate Change and Childhood Asthma: A Scoping Review.

Pediatric pulmonology, 60(11):e71373.

BACKGROUND: Warming temperatures are associated with increasing incidence and severity of wildfires, extreme rainfall, and large storms.

METHODS: To provide an updated review of research into the impacts of climate-driven environmental factors on childhood asthma, and to frame future research needs, we carried out a scoping review focused on studies reported over the past 5 years in PubMed, Scopus, Embase, and Global Health.

RESULTS: Data appear to be especially strong for an association of exposure to wildfire smoke (WFS) with adverse asthma outcomes, including in children. Additional evidence links severe weather events, temperature extremes, and extended pollen seasons with worse asthma outcomes. Experimental studies have established several specific pathways that could link these environmental factors with disease and could suggest potential preventive or treatment strategies.

CONCLUSIONS: Future research needs to include a better understanding of key triggers and mechanistic pathways, and on mitigation strategies that could be applied immediately. Given the complex and multifactorial nature of how environmental exposures contribute to asthma, computational approaches will probably be critical to define causality in complex exposure mixtures, improve environmental exposure forecasting, and inform personalized asthma management.

A mechanistic model of endotherm hibernation applied to the endangered mountain pygmy possum under climate change.

Ecology, 106(11):e70238.

Hibernation is an important strategy used by many endotherms to conserve energy and water. Global warming is changing species' phenology and hibernation patterns, but whether such changes are beneficial or harmful depends on the species' life history traits, physiology, morphology, and behavior. Mechanistic niche models can be used to make strong inferences on such responses by explicitly quantifying the consequences of changed hibernation patterns for energy and water requirements. However, they have yet to be adapted to heterothermic species. Here, we address this problem by extending the endotherm biophysical model of the NicheMapR package to encompass torpor. This model accurately predicts the energy requirements of hibernating mammals over a broad size range from microbats to bears. We then used this approach to assess the effect of climate change on a Critically Endangered hibernator, the Australian mountain pygmy possum (Burramys parvus). Specifically, we contrasted conditions for the year 2010 with two future climate-change scenarios (2or 4°C of average warming) to identify: (i) the projected changes in energy and water requirements; (ii) the advantage conferred by hibernating for the species' energy and water requirements; and (iii) the areas across southeastern Australia that could continue to support hibernation. We projected an 11%-43% reduction in hibernation hours for the mountain pygmy possum under our two climate-change scenarios. In consequence, requirements for energy increased by 4%-21%, and for water by 10%-34%. Under current conditions, hibernation reduces annual energy requirements by 44%-52% and annual water requirements by 32%-42%, but in our projections, this energetic and hydric benefit of hibernation will decline due to climate change. The total area where hibernating and not hibernating is energetically equivalent is projected to increase by 60% under 4°C warming, preventing recovery from the species' severely restricted distribution at present. Our results show that climate change will have a profound impact on the duration and patterns of hibernation, a key survival strategy, for Burramys. Our framework for analyzing changing hibernation patterns provides a new and general way to test the vulnerability and plasticity of hibernating endotherms under global change.

Knowledge translation of climate change research into public health action: a scoping review.

Frontiers in public health, 13:1632799.

BACKGROUND: There are gaps in translating climate change research into public health action at the global level. Knowledge translation refers to the methods used to bridge the gap between knowledge and action. Given the significant impacts of climate change on health, it is essential to integrate climate research into health decision-making processes. This integration ensures that evidence effectively informs policies and practices at all levels, leading to more timely, equitable, and impactful public health responses.

OBJECTIVE: This scoping review examines key approaches and identifies gaps in knowledge translation methods for integrating climate change research into public health decision-making.

METHODS: A systematic search of the literature was conducted in PubMed, CINAHL, and Scopus using a predefined search string to identify studies on climate change and health published between January 1, 2003, and March 1, 2024, with no geographic restrictions. Retrieved articles were screened and data extracted using Covidence software. Thematic analysis was performed in ATLAS.TI employing Braun and Clark's six-step method. The identified knowledge translation approaches were categorized according to the Cochrane Knowledge Translation Framework.

FINDINGS: Our findings highlight five primary knowledge translation approaches: (1) monitoring the coverage of climate change and health across media, scientific literature, and government responses; (2) engaging citizens of all ages in participatory activities to address local climate challenges and co-develop policy solutions; (3) integrating knowledge generation, synthesis, and dissemination for effective communication; (4) emphasizing advocacy and education to foster collaborations and gain support from decision-makers; and (5) leveraging health impact assessment tools to guide decision-making related to climate change and health. Nonetheless, we did not find any primary studies on climate change research and knowledge translation in Low- and Middle-Income Countries (LMICs).

CONCLUSION: There is a need for primary studies on the knowledge translation of climate change research, especially in relation to adaptation, into meaningful public health actions that can inform decision-making and contribute to building climate-resilient health systems in LMICs.

Molecular interactions between plants and arthropod herbivores in the context of climate change.

Journal of experimental botany pii:8321471 [Epub ahead of print].

Climate change is a powerful force that is changing the interactions between plants and biotic stressors. While the consequences of increased temperature and decreased water availability on molecular plant-pathogen interactions have been widely documented, the effects of global warming on molecular plant-herbivore interactions are less understood. In this review, the current knowledge on molecular interactions between plants and arthropod herbivores is compiled in the context of climate change, with a focus on the consequences of drought and warm temperatures. Mostly from transcriptomic approaches, extensive alterations have been found in the basal state of plants under mild changes in climate conditions. Although less studied, environmental conditions also affect molecular mechanisms in herbivores. Therefore, the molecular interaction between plants and herbivores is profoundly affected by specific environmental conditions, and the final consequence will depend on the climate-plant-herbivore specificities. Understanding how climate changes affect specific plant-herbivore interactions will help determine how global warming will affect crop production in the future.

Understanding crop performance and pest control under climate change requires considering interactions among warming, elevated CO2, and trophic interactions.

Scientific reports, 15(1):39519.

Investigating the combined effects of climate change and species interactions on species advances climate change research. However, such combined effects are understudied and may defy current hypotheses that focus on individual effects. We empirically examined how multiple environmental stressors (elevated temperature and CO2) and trophic interactions (herbivory and predation) interactively affect crop performance and pest control in a tri-trophic agroecosystem including soybean (Glycine max), aphid (Aphis glycines), and ladybeetle (Coccinella septempunctata). Temperature (control/+2 °C/+4 °C), CO2 (ambient/elevated), and trophic treatments (soybean/soybean-aphid/soybean-aphid-ladybeetle) were conducted in environmental chambers. Plant, herbivore, and predator traits (soybean nutrient content, defense, reproduction, and aphid and ladybeetle performance) were greatly influenced by interactions between abiotic (temperature, CO2) and biotic (trophic) factors, often contradicting current hypotheses. For example, aphids reduced seed number; ladybeetles generally suppressed aphids and rescued seed production. However, this biocontrol was compromised under elevated temperature and CO2, suggesting climate-induced changes in biocontrol effectiveness. We conclude: (1) To improve predictability, climate change research should include abiotic-biotic interactions as important mechanisms. (2) Empirical studies considering local climate-trophic interactions are critical for predicting regional food security. (3) While this study highlights species' plastic responses to climate change, experimental evolutionary studies will be needed to understand potential evolutionary adaptation.

Climate change projections using CMIP6 GCMs and downscaling approaches in the Upper Wabe Shebele Basin, Ethiopia.

Scientific reports, 15(1):39521.

Climate change presents considerable challenges, particularly for agrarian countries like Ethiopia. This study employed modeling and scenario-based methodologies to examine anticipated changes in precipitation and temperature in the Upper Wabe-Shebele River Basin. The study compared baseline data from 1986 to 2022 with two future projection periods: 2023 to 2053 and 2054 to 2086. Various bias correction techniques were applied to the precipitation and temperature datasets. For precipitation, the methods utilized include linear scaling, distribution mapping, empirical quantile mapping, and power transformation were utilized. Conversely, for temperature, power transformation was substituted with variance scaling, while the other three methods were employed for both datasets. The statistical downscaling model and climate model data for hydrologic modeling were calibrated and validated. The findings show a 35.89% reduction in precipitation and a 2.03 °C increase in temperature compared to the baseline. Future projections suggest that under the high emissions scenario SSP5-8.5, mean annual rainfall is expected to decline by 41.76% in the 2040s by 50.33% in the 2070s. Even under the lowest emissions scenario SSP1-2.6, rainfall is anticipated to decrease by 21.19% in the 2040s and by 30.25% in the 2070s. Temperature is projected to increase by 0.89-3.6 °C depending on the emissions scenario and time period. Additionally, both precipitation and temperature are also expected to show variations in their monthly distributions throughout the year. These climatic changes are expected to significantly reduce water availability and agricultural productivity.

Reviewing the Great American Biotic Interchange: climate change as a trigger for biodiversity dispersal.

Proceedings. Biological sciences, 292(2058):20251745.

The Great American Biotic Interchange (GABI), during which an intense biodiversity interchange occurred between South and North America (SA and NA), strongly affected the biodiversity of the Americas. Despite its importance, there are still knowledge gaps regarding the factors triggering species dispersion, the taxonomic groups that first dispersed, the age at which dispersions began and intensified, and whether there was a main dispersal direction through the continent (from NA to SA or vice versa). To fill these gaps, we conducted a scientific literature review of the GABI, searching for studies with information regarding dispersal age, taxonomic groups (invertebrates, amphibians, non-avian reptiles, birds, mammals and plants), dispersion direction (towards SA or NA) and the type of data used as the source of evidence (fossil, molecular or extant species). We also investigated the effect of the climatic dynamic on the biodiversity dispersal through the relationships between oxygen-isotope levels (δ[18]O, as a proxy of past temperatures) and the number and geological age of dispersal records. Only 41.8% (87 publications) of the studies included information on biodiversity dispersion during GABI. We found evidence of GABI starting at 23 million years ago (Ma) and becoming a continuous process from approximately 15 Ma. Cooling periods after the Miocene Climate Optimum favoured continuous dispersals, which have since intensified. Studies based on molecular data recovered more closely related to the intermediate ages of dispersal records. In addition, birds, plants and mammals were displaced first, whereas amphibians were displaced last.

What makes physicians implement climate change and heat adaptation measures in outpatient practices? A mixed-methods study.

Public health, 249:106046 pii:S0033-3506(25)00492-5 [Epub ahead of print].

OBJECTIVES: Health impacts of climate change are becoming increasingly apparent and require adaptation in the healthcare sector. We aimed to identify behavioural determinants among physicians in outpatient practices for the implementation of climate change adaptation measures with a focus on heat.

STUDY DESIGN: We employed a sequential explanatory mixed-methods design with an online cross-sectional survey and focus group discussions (FGD).

METHODS: Data were collected in a physician network in Germany, from April to May 2023. We used Protection Motivation Theory (PMT) as a theoretical model to assess behavioural determinants for the implementation of eight climate change adaptation measures in outpatient practices. Data were analysed using descriptive statistics and logistic regressions and qualitative content analysis for the FGDs.

RESULTS: 67 physicians participated in the survey (62.6 % response rate). On average, physicians reported implementing three out of eight proposed adaptation measures, 91.0 % implemented at least one. In the regression analyses, self-efficacy was a significant predictor for adjusting medication, adjusting schedules, and protecting buildings from heat. Response-efficacy was a significant predictor for educating oneself and the team, informing patients, and advising on active cooling. The FGDs with 18 physicians provided insights into aspects influencing self-efficacy, i.e. lack of time, and response efficacy, i.e. patients' adherence to physicians' recommendations. They also revealed that perceived responsibility for a measure was another determinant outside of PMT.

CONCLUSION: This study highlights the need to improve physicians' self-efficacy to implement measures, for example by offering clear guidelines. Moreover, it stresses the need to further investigate the effectiveness of single adaptation measures.

The Importance of Sleep in Animals and Its Potential Vulnerability to Climate Change.

Annual review of animal biosciences [Epub ahead of print].

Sleep is a universal behavior across animals, critical for physiological homeostasis, cognitive function, and development. Throughout evolution, animals have adapted to environmental changes, but current rapid climate change may threaten sleep patterns adapted to specific ecological niches through rising temperatures, shifting precipitation, and extreme weather. Despite the importance of sleep, climate change-driven sleep disruptions are not well-considered. We introduce the importance of sleep and examine how climate change affects sleep in different biogeographical zones (polar, tropical, dry, and marine and coastal regions), highlighting region-specific vulnerabilities. Furthermore, we discuss the cascading effects of sleep disruption on species interactions, population dynamics, and ecosystem functioning. We emphasize the need for long-term ecological studies, advances in sleep-measurement technologies in free-living animals, and the integration of sleep ecology into conservation strategies. Future priorities include assessing variability within and between individuals, the fitness costs of sleep loss, and the potential for evolutionary adaptation.

PloS one, 20(11):e0315482 pii:PONE-D-24-45324.

Climate change severely threatens global public health, with sub-Saharan Africa (SSA) projected to experience profound impacts. This scoping review aimed to provide a comprehensive overview of current research on climate change and its health implications in SSA while identifying research gaps and outlining the necessary resources and policy interventions to strengthen public health resilience in the region. Literature was retrieved from four databases (PubMed, Scopus, Embase and Web of Science) using the keywords "climate change," "health," and "sub-Saharan Africa" and this study was conducted using the PRISMA framework. The inclusion criteria were peer-reviewed studies published in English between January 1, 2001, and August 1, 2024, that examined the effects of climate change in SSA, assessed its impacts on health outcomes,A total of 7851 journal articles were identified from the initial search, and after screening, 153 studies were included for review. The included studies were published between January 2001 and August 2024. Although extensive studies have been conducted on extreme heat (71 studies), drought (45 studies), extreme precipitation events (52 studies), and flooding (34 studies), important themes such as air quality (10 studies), chemical water quality (8 studies) and natural disasters (8 studies) have been understudied. Additionally, this scoping review revealed a geographical gap in climate change and health studies, as only 24 out of 53 countries in sub-Saharan Africa were represented. The key deficiencies identified include limited funding, technological constraints, inadequate climate policies, and a lack of community-focused adaptation plans. Moreover, this review highlights the urgent need for resilient healthcare systems capable of addressing climate-related health risks effectively. Addressing these gaps is essential for developing targeted strategies to mitigate climate change's health impacts and increase resilience in SSA communities. This review aims to inform policymakers, researchers, and stakeholders about critical areas requiring attention and investment by enhancing our understanding of these challenges and gaps. Strengthening research capacities, fostering collaboration, and implementing evidence-based policies are imperative steps toward achieving sustainable health outcomes in the face of a changing climate in SSA.

Strange Plants And The Weirding Climate: Parasitic Plant Physiology Under Climate Change.

Plant & cell physiology pii:8320493 [Epub ahead of print].

Parasitic flowering plants are often seen as keystone species due to the broad influence they exert on communities worldwide. Positive and negative effects associated with parasitic plant infestation have been documented for a variety of species in multiple locations and under different experimental conditions. However, the impact of the different drivers of climate change on these plants has only recently begun to be analyzed in more detail. In this context, most studies have dealt with modelling future distribution ranges of parasite species and assessing potential ecological impacts. Building on this work, this review discusses studies that have employed a more mechanistic approach to investigate different aspects of parasitic plant physiology under climate change. Considering results obtained for both hemi- and holo-parasites, I hypothesize that, in the presence of conditions that improve parasite performance, such as reduced intraspecific competition or increased diversity of host species, elevated levels of atmospheric CO2 can partially alleviate the negative impact of parasitism on host growth. However, this reduction of negative impacts is potentially hampered by other drivers of climate change, such as extreme high temperatures and severe drought events. Future research should strive to analyze the combined impact of different components of climate change simultaneously, preferably considering a wider diversity of parasitic plant species.

Seroprevalence of seven climate-sensitive zoonoses in Greenland and northern Sweden (1998-2017): High antibody prevalence against Rickettsia and Leptospira, with Leptospira possibly linked to global warming.

One health (Amsterdam, Netherlands), 21:101244.

BACKGROUND: Climate change may alter zoonotic disease patterns in the Arctic, yet knowledge remains limited.

DESIGN: Antibodies to seven zoonotic pathogens were analyzed in 660 unselected human sera drawn from serum banks from Greenland (n = 460) and Northern Sweden (n = 200) (1998-2017), frequency-matched with respect to sex, age, ethnicity and place of living. Greenlandic samples were tested for Francisella tularensis, Brucella melitensis, Brucella abortus, Coxiella burnetii, Rickettsia spp., and Leptospira spp., while Swedish samples also included Borrelia burgdorferi sensu lato (Bbsl) and tick-borne encephalitis virus (TBEV).

RESULTS: Leptospira seroprevalence was higher in Greenland 2013 (18 %, 95 % CI 13-24 %) than in Sweden 2012-2017 (4 %, 95 % CI 2-8 %) and increased significantly over time in West Greenland (1998: 2.5 %, 95 % CI 0.8-6 %; 2013: 30 %, 95 % CI 18-45 %, p < 0.001, OR 16.7, 95 % CI 5.7-48.9). Rickettsia seroprevalence remained stable over time (12 %, 95 % CI 5-24 %). Seroprevalence of F. tularensis and B. melitensis/abortus in Greenland 2013 was less than 1 %. In Sweden, seroprevalence was 1 % (95 % CI 0.1-4 %) for B. melitensis/abortus, 2 % (95 % CI 0.1-5 %) for Bbsl, 3 % (95 % CI 1-6 %) for F. tularensis, and 5 % (95 % CI 2-9 %) for TBEV. Antibodies to C. burnetii were not detected in any sample. Two of 81 polar bear samples from East Greenland (2016-2023) were seropositive for Leptospira spp.

CONCLUSIONS: This first report on human Leptospira infection in Greenland highlights rising seroprevalence, possibly linked to contaminated water and global warming. Findings emphasize widespread Rickettsia exposure in northern regions and tick-borne pathogens in Sweden, underscoring the need for updated public health data to inform public health planning.

Accelerated rifting in response to regional climate change in the East African Rift System.

Scientific reports, 15(1):38833.

Continental rifting is influenced by interactions between tectonic, magmatic, and surface processes, with the latter strongly dependent on regional climate. We test the role of regional climate variability on rift system behavior, by investigating fault slip rate changes in the South Turkana Basin (Lake Turkana Rift, northern Kenya) at the end of the African Humid Period. Throw rates on 27 faults examined during the African Humid Period (9,631-5,333 yr BP) and post-African Humid Period (5,333 yr BP-present) exhibit a mean 0.17 ± 0.08 mm/yr increase during the drier, post-African Humid Period. Numerical simulations reveal Coulomb stress changes from two loading sources that may explain these changes: (1) reduced vertical loading from a 100-150 m lake level drop, and (2) increased magmatic loading from enhanced mantle melt production due to reduced lake loading. An increase in magma flux of > 0.1 km[3]/kyr below the South Turkana Basin results in Coulomb stress changes exceeding those expected from a 100-150 m lake level drop. We provide the first empirical evidence of increased fault activity in response to climate-induced lake level changes in the East African Rift System over time scales of 10[3]-10[4] years, and reveal that climate-tectonic interactions are enhanced in magmatically active rift systems.

Tracking submediterranean ecotone shifts under climate change scenarios using marcescent oaks as indicators.

Scientific reports, 15(1):39201.

The submediterranean is an ecotone distributed across southern Europe and north Africa, marking the transition between temperate and mediterranean climates. This is a remarkable climatic and vegetational dynamic area, with major shifts driven by changes in climate since the Late Quaternary. We explore future range shifts of the submediterranean ecotone caused by climate change using marcescent oaks as a proxy, considering their high prevalence in forests under such conditions. Our results confirm the ongoing dynamism of this ecotone, which is likely to expand its range northwards, where marcescent oaks will overlap Eurosiberian forests dominated by deciduous and temperate species. Conversely, in the southwestern Mediterranean, a loss of suitability is predicted, with remaining suitable habitat only at higher altitudes or along coastal regions, promoting scattered refuge suitable areas. To preserve these forests, further research is needed to assess the future ranges of individual species based on high-resolution models, to plan management and restoration strategies within a context of high disturbance by land use.

Climate Change in Clinical Practice.

Journal of obstetric, gynecologic, and neonatal nursing : JOGNN pii:S0884-2175(25)00296-5 [Epub ahead of print].

Climate change has resulted in increased extreme weather events, including prolonged heat waves, extended wildfire regions and seasons, and more frequent hurricanes and flooding. These events create problems with access to health services, shelter, potable water, diminished air quality, and increased incidence of vector-borne disease that affect the health of pregnant women and families. Nurses caring for pregnant women must have the knowledge to identify and respond to climate change-related health risks. Nursing care related to heat, wildfires and wildfire smoke, hurricanes, and flooding must include accurate assessments and discharge planning that addresses women's health conditions within the context of environmental risks. The purpose of this article is to raise awareness of the clinical nursing care of pregnant women related to heat, wildfires, hurricanes, and flooding in the era of climate change.

Mechanisms of Hypoxia Formation in the Ariake Sea, Japan, under Climate Change: Insights from Orthogonal Design.

Environmental science & technology [Epub ahead of print].

Seasonal hypoxia events pose significant threats to the environment and ecosystems of coastal areas. Temperature, river discharge, and nutrient loading are key drivers, but their relative importance is affected by spatial variations in the coastal topography and ecological structure. This study used the Taguchi method to evaluate the impacts of these factors on dissolved oxygen (DO) dynamics in the Ariake Sea with a particular focus on the summer flood period. Each factor was set at three levels to represent potential climate change scenarios, offering a key advantage in efficiency by enabling reliable assessment with fewer simulations than the 27 trials required in a full factorial design (3[3]). The results suggest that increased temperature and river discharge reduced DO throughout the year, while low nutrient loading enhanced DO in well-mixed nonsummer months. In summer, nutrient loading and river discharge were the primary drivers of hypoxia, contributing 51.5% and 41.2%, respectively (p < 0.05, at St. 3). A lagged autumnal response linked to summer floods showed that discharge explained 88.6% of DO decline (p < 0.05, at St. 1). Furthermore, experimental simulations indicated that doubling both discharge and nutrient loading expanded hypoxia to nearly two-thirds of the sea, threatening benthic fauna and ecosystem stability.

Climate Change, Air Pollution and the Global Obesity Syndemic: a Review of Current Evidence.

Current obesity reports, 14(1):78.

PURPOSE OF REVIEW: Climate change and obesity are two converging global crises with complex and interrelated pathways. This review aims to synthesize recent evidence linking climate-related exposures, including rising ambient temperatures, air pollution, and urbanization to the pathogenesis of obesity. It also explores how obesity itself increases vulnerability to heat injury and environmental stress, highlighting the bidirectional nature of this syndemic.

RECENT FINDINGS: Epidemiologic evidence has supported associations between air pollution and increased body mass index, central adiposity, and metabolic dysfunction across the lifespan. Mechanistic research implicates impaired thermogenesis, chronic inflammation and oxidative stress, endocrine disruption, hypothalamic inflammation, and microbiome dysbiosis as key pathways linking environmental exposures to adiposity. Obesity further amplifies the physiological burden of climate-related stressors, such as heatwaves, due to reduced heat dissipation and altered hormonal responses. Anti-obesity medications may exacerbate heat-related risks via dehydration and gastrointestinal side effects. Urban greenness appears to offer a partial protective effect, modulating the obesogenic impact of air pollution and heat, particularly in low-income settings. Obesity and climate change share common socioeconomic, behavioral, and environmental drivers. Addressing this dual burden requires integrated strategies that promote environmental sustainability and metabolic health. These include green infrastructure, active transportation, climate-adapted clinical care, and public health strategies that reflect planetary health principles. Recognizing obesity not only as a medical condition but also as an environmentally influenced disorder is essential for effective, future-oriented prevention and intervention efforts.

Climate Change and Cardiovascular Health: Environmental Stressors, Mechanistic Insights, and Clinical Perspectives.

Reviews in cardiovascular medicine, 26(10):40069.

Climate change poses a significant threat to cardiovascular health through the combined effects of extreme temperatures, air pollution, and extreme weather events. Short-term heat exposure raises mortality risk by 3.80%, while long-term exposure to particulate matter (PM2.5, with an aerodynamic diameter of ≤2.5 micrometers) increases cardiovascular mortality by 11-20%. Key mechanisms include thermoregulatory stress, inflammation, autonomic nervous system dysfunction, prothrombotic state, and psychosocial stress. Vulnerable groups, such as older individuals and those with cardiovascular diseases, also face a higher risk. Epidemiological studies have shown that for every one-standard-deviation increase in the number of days with excess heat factor, the overall mortality risk rises by 3.80%. Proposed interventions include high-efficiency particulate air (HEPA) purifiers, optimized cooling centers, and low-emission zones. However, key research gaps remain in the effects of multi-stressors, protection strategies, exposure assessment, and climate-driven disease projections. Multidisciplinary collaboration is crucial for mitigating climate-related cardiovascular risks. This review provides a comprehensive overview of the current situation regarding climate change and cardiovascular health, summarizing the results of epidemiological, pathological mechanisms, and policy research.

Climate change is reshaping the epidemiology of dermatologic diseases in the Global South through rising temperatures, UV radiation, extreme weather events, and shifting ecosystems. These environmental stressors exacerbate thermal injuries, infectious and inflammatory dermatoses, and neglected tropical diseases such as cutaneous leishmaniasis, mycetoma, and scabies. Vulnerable populations-including displaced communities, persons with albinism, and outdoor workers-face disproportionate risk. This article highlights the dermatologic impacts of climate change, emphasizing the need for integrated surveillance, accessible care, and climate-resilient health systems.

Climate Change and Infectious Diseases in Dermatology.

Dermatologic clinics, 44(1):45-65.

Human activities have led to climate change, resulting in global warming, ocean warming, and more frequent extreme weather events (EWEs). Each of these has the potential to amplify infectious diseases with skin manifestations. Alterations in the skin microbiome due to rising temperatures and humidity may increase infection risk. Global warming has led to expanding geographic ranges of vector-borne diseases. Warming waters have similarly increased the risk of waterborne diseases. EWEs are associated with increased incidence of cutaneous infections. Land-use change, both a cause and effect of climate change, increases the risk of zoonotic spillover.

Machine learning for predicting climate change impacts on Pseudopithomyces chartarum spore counts: a risk indicator of facial eczema.

New Zealand veterinary journal [Epub ahead of print].

AIMS: To determine the importance of 11 climate variables on pasture spore count of Pseudopithomyces chartarum, a risk indicator of facial eczema (FE), and to forecast spore counts in New Zealand until 2100, using longitudinal P. chartarum pasture spore count data.

METHODS: Between 2010 and 2017, spore counts (n = 6,975) were collected from 862 paddocks spread over 102 farms in the North Island of New Zealand. Historical and projected climate data were obtained from the National Institute of Water and Atmospheric Research. The spore count dataset was merged with climate data from corresponding locations, incorporating time lags of 1-53 weeks. Linear regression models were fitted for describing crude associations, while random forest models were fitted for determining variable importance and predicting future spore counts.

RESULTS: Mixed-effect linear regression models explained up to 11% of the variance of log-transformed spore counts by a single lagged climate covariate. The best-fit random forest model had a testing accuracy of 80% in classifying low or high FE risk (> 20,000 spores) with an R[2] value of 43%. The random forest models suggested time-dependent importance of soil temperature at 10 cm depth, solar radiation, potential evapotranspiration, vapour pressure, soil moisture and minimum temperature, while no or weak evidence of variable importance was found for maximum temperature, rainfall, mean sea level atmospheric pressure, relative humidity and wind speed. Over the next 80 years, our model predicted an increase in the seasonal mean spore counts in the study farms by a mean of 17% (min 6, max 30%) under the high-end greenhouse gas emission scenario (representative concentration pathways (RCP) 8.5). Every decade was associated with an increase in the probability of high-risk spore counts (> 20,000) by 14-22% for the moderate to high emission scenarios (RCP 4.5-8.5). The model indicated increased peak spore counts across most regions over the next 80 years. Specifically, the entire North Island and three districts in the South Island were projected to have high mean peak spore counts by 2100.

These findings could be used to target high-risk areas to implement mitigation or adaptation measures for FE. In addition, the study highlights the value of ecological data for forecasting environmental disease risks to enhance preparedness for climate change.

Impacts of extreme climate change on terrestrial ecosystem carbon storage in China.

The Science of the total environment, 1005:180890 pii:S0048-9697(25)02530-6 [Epub ahead of print].

Extreme climatic events are occurring with increasing frequency, posing significant challenges in assessing their impact on terrestrial carbon storage. Based on daily meteorological observations from 1990 to 2019 across China, the trends and abrupt changes in 26 extreme climate indices were systematically analysed using the Theil-Sen estimator and Mann-Kendall test. A random forest regression model was constructed by integrating high-resolution remote sensing, meteorological, and topographic data to predict the spatial distribution of aboveground biomass carbon (AGBC). Furthermore, the XGBoost algorithm combined with Shapley additive explanations (SHAP) was employed to quantify the driving effects of extreme climate indices on AGBC and their spatial heterogeneity. The results reveal that over the past three decades, warm and extreme precipitation events have significantly intensified, whereas cold events have markedly declined. A notable shift in climate occurred between 1998 and 2005. During this period, the AGBC increased steadily, with forests, grasslands, and wetlands exhibiting significant growth. The SHAP analysis identified very wet days (R95pTOT), diurnal temperature range (DTR), annual maximum value of daily minimum temperature (TNx), and annual total precipitation on wet days (PRCPTOT) as the dominant climatic drivers of AGBC variation. Their ecological impacts demonstrated strong nonlinear responses and spatial differentiation. In humid eastern regions, these factors generally enhanced carbon sequestration, whereas in arid and high-altitude western regions, they may exert inhibitory effects. This study provides robust quantitative evidence for understanding the complex, nonlinear interactions between extreme climate events and ecosystem carbon dynamics and offers scientific guidance for regional carbon sink management and climate adaptation strategies to support the dual carbon goals of China.

Climate change reflected in 40-year isotopic composition trends of precipitation in Slovenia.

Environmental research pii:S0013-9351(25)02539-3 [Epub ahead of print].

Long-term monitoring of stable isotopes in precipitation (δ[18]O, δ[2]H), alongside meteorological data, is key to understanding how large-scale hydroclimate variability influences regional and local climate. This study presents one of the longest records in Central and Southeastern Europe: the multi-decadal (1981-2024) dataset of monthly composite precipitation stable isotope records from Ljubljana, Slovenia. Ten-year rolling averages of δ[18]O, δ[2]H, and d-excess are increasing (+0.02 ‰, +0.18 ‰, and +0.05 ‰ per year, respectively), consistent with regional warming. Seasonal patterns were evident, with elevated d-excess values during autumn. The decomposition of the δ[18]O, δ[2]H and d-excess time series using Hilbert-Huang Transform revealed statistically significant annual oscillations in all variables. These oscillations correlated strongly with the annual oscillation of temperature, but a lag of 2-3 months was identified for d-excess. Lower-frequency (multi-year) oscillations of d-excess were also observed. HYSPLIT back-trajectory analysis confirmed a significant contribution of Mediterranean-sourced air masses to autumn precipitation, but did not explain d-excess oscillations. Similar results were observed also for coastal (Portorož, Slovenia) and continental (Vienna, Austria) stations. The findings imply an accelerating, exponential-like isotopic response to warming that has already propagated into the water cycle, providing isotope evidence that precipitation-surface water-groundwater interactions in investigated region changed in last decade.

Climate change and flood susceptibility in Bocas del Toro, Panama: A multi-criteria spatial analysis approach.

Journal of environmental management, 395:127741 pii:S0301-4797(25)03717-X [Epub ahead of print].

Though Bocas del Toro province lies in the Panamanian Caribbean region regarded as "ground zero" in the global climate emergency, responses to frequent inland flooding remain reactive due to the lack of a comprehensive flood hazard map. This study integrated publicly available spatial data with elicitation from regionally-specific subject matter experts to map present and future flood prone zones in the province using the Analytical Hierarchy Process (AHP) and Weighted Sum tool, based on the shared socioeconomic pathways (SSP). Rainfall and temperature data were analyzed to predict future flood related extreme events. Eight flood-conditioning factors (elevation, slope, topographic wetness index, drainage density, distance from rivers, flow accumulation, Normalize Different Vegetation Index, and land cover) were integrated with extreme historic and projected rainfall using AHP-derived weights to derive the maps. To assess flood-zone sensitivity, rainfall weight was reduced by 5 % and sequentially reallocated to the other factors. Meteorological data collected locally showed no significant temporal trend in extreme rainfall and heat as projected. Flood susceptibility maps, validated with an AUC of 0.98, revealed that Changuinola has the highest proportion of current (30.38 %) and projected flood-prone areas under SSP2-4.5 (35.06 %) and SSP5-8.5 (30.76 %), while Almirante was projected to experience the greatest spatial expansion under both scenarios. While flood-prone zones in Almirante and Changuinola were most sensitive to distance from rivers and flow accumulation respectively, those of Bocas del Toro and Chiriquí Grande were most sensitive to elevation. The study recommends proactive mitigation through controlled development near waterways, elevation-informed land use planning, and preservation of natural vegetation. Future research should assess the impact of land use change on predicted flood zones or map areas susceptible to marine-driven flooding not covered in this study.

Global climate change-driven poleward shifts in suitable habitat distribution and niche differentiation of benthic euryhaline Lateolabrax species.

Marine pollution bulletin, 222(Pt 3):118950 pii:S0025-326X(25)01426-2 [Epub ahead of print].

Understanding species' response mechanisms to climate change is fundamental for predicting future biodiversity patterns and formulating conservation strategies. This study utilized the Maxent model to examine the effects of global warming on the suitable habitat distribution of representative benthic euryhaline Lateolabrax species. By integrating current environmental variables with projected data under four future climate scenarios (RCP2.6, RCP4.5, RCP6.0, and RCP8.5), we predicted changes in their suitable habitats, centroid shifts, and niche overlaps. The results revealed that the suitable habitat of L. maculatus is primarily shaped by primary productivity and distance offshore; L. japonicus shows sensitivity to maximum light intensity and seawater temperature; whereas offshore distance and seawater iron ion concentration are key determinants for L. latus. Among the three species, L. latus demonstrated the greatest adaptability, maintaining a relatively stable and even expanding suitable habitat under future climate scenarios, with minimal adverse effects from global warming. In contrast, suitable habitat areas for L. maculatus and L. japonicus exhibited varying degrees of contraction. Over time, niche overlap-including both ecological niche and geographic range overlap-generally decreased among the three species, indicating enhanced niche differentiation and spatial segregation. Additionally, the distribution centroids of L. japonicus and L. maculatus shifted poleward, with L. maculatus experiencing the largest centroid shift-approximately 1793 km northward under the 2100 RCP8.5 scenario. This study provides valuable scientific insights into the responses of Lateolabrax species to climate change and their projected distributional dynamics, offering a critical foundation for the conservation and sustainable management of Lateolabrax resources.

Climate change and malaria in Chiredzi District, Zimbabwe: emerging evidence and pathways towards malaria prevention.

Malaria journal, 24(1):377.

BACKGROUND: Climate change can influence malaria incidence directly and indirectly, impacting vector and parasite dynamics, along with socioeconomic factors influencing malaria risk. In Zimbabwe there is a paucity of research linking climate change, environmental factors, and malaria incidence, hindering coordinated efforts for malaria elimination. Accordingly, the aim of the study was to explore the link between climate change, environmental factors, and malaria incidences, from 2010 to 2022, in Chiredzi district, Zimbabwe.

METHODS: A transdisciplinary approach was applied, combining quantitative weather data from weather stations, malaria incidence data and insights from focus group discussions which were used to glean people's perceptions and knowledge of climate change and malaria in Chiredzi District. Participatory mapping showing hot spots of malaria incidence were also utilized. Statistical analysis in MATLAB was used to analyse the weather and malaria data and a P-value of 0.0479 was obtained which is deemed as statistically significant. ATLAS.ti was used to qualitatively analyse data from the focus group discussions.

RESULTS: Key results from the study show evidence of climate change in Chiredzi district manifesting through an increase in rainfall, increase in temperature, change in seasons and extreme weather patterns. Furthermore, there is a positive relationship between changes in climate and an increase in malaria incidence. However, in some years the relation is negative, and this can be attributed to other factors. Similarly, malaria incidence is also related to other socioeconomic and environmental factors such as poverty and migration which are further exacerbated by climate change. Malaria incidence is also attributed to other environmental and socio-economic factors.

CONCLUSIONS: Further studies with extended datasets that span a longer period need to be carried out. Likewise forecasting malaria incidence based on current climate, environmental and socio-economic conditions is crucial for advocating transformative malaria prevention programs, emphasizing the importance of inclusive partnership and adaptation to a changing climate. New malaria prevention programs that consider the impact of a changing climate on malaria, local environmental and socio-economic factors are urgently needed.

Climate change impacts on ocean light in Arctic ecosystems.

Nature communications, 16(1):9798.

Climate change is causing major sea ice losses, leading to increased light availability across polar marine ecosystems, however the consequences are largely unknown. We quantify how future conditions for sea ice and snow, storm-driven waves, clouds, ozone, air and ocean temperature, and chlorophyll-a will affect seasonal absorption and reflection of light in Arctic seas, alongside growth and survival of fish. Using four CMIP6 model inputs and a spectral radiative transfer model, we predict a 75-160% increase in visible light by 2100 in the Northern Bering, Chukchi, and Barents Seas. We predict increased sunlight and warmer summer waters, with reduced phytoplankton levels, will negatively impact cold-water fish species growth and survival during summer, demonstrated here for polar cod. Asynchrony in prey and light availability, with prolonged periods of warmer waters, will reduce polar cod survival in the fall and restrict habitats in these regions after 2060. Warmer-water species like walleye pollock and Atlantic cod will be less impacted but may struggle at high latitudes during the polar night. Ocean warming coupled with increased light availability will accelerate changes in Arctic ecosystems, compromising the growth and survival of Arctic species in transitional zones and facilitating the northward expansion of boreal species.

Educator perspectives on integrating climate change and environmental sustainability into occupational therapy education.

Work (Reading, Mass.) [Epub ahead of print].

BackgroundClimate change has been identified as the biggest threat to global public health.[1] Despite the clear connection between negative health outcomes and anthropogenic climate change, there are few guidelines for curricular inclusion within healthcare education, including occupational therapy (OT). However, the World Federation of Occupational Therapists has emphasized the importance of sustainability,[2] and the American Occupational Therapy Association published a policy asserting the profession's commitment to addressing these topics.[3]ObjectiveThis study explored the perspectives of OT educators in the United States on the relevance, importance, and feasibility of integrating climate change and environmental sustainability into OT education programs.MethodsAn online Qualtrics survey was distributed, with 64 respondents across the United States. Descriptive and inferential statistics were conducted to determine relationships between respondent responses to question pairs. Qualitative responses underwent thematic analysis.ResultsMost educators acknowledged the relevance and importance of addressing climate change and environmental sustainability. Several barriers hindered implementation, including an already overloaded curriculum with a lack of explicitly related Accreditation Council for Occupational Therapy standards, limited time, a lack of awareness of how climate change and environmental sustainability fit into OT programs, and skepticism about climate change as relevant to OT practice.ConclusionsThe findings indicate varied perspectives among US-based OT faculty. They suggest a need for educational resources that link climate change and environmental sustainability to health, occupation and other core tenets of OT and offer strategies for integrating this content into OT education.

Rapid Northward Expansion of the Blacklegged Tick, Ixodes scapularis, in Response to Climate Change.

Global change biology, 31(11):e70591.

Climate change rapidly drives species range dynamics, prompting many terrestrial organisms to shift northward to higher latitudes and forcing new species-species and species-environment interactions. The blacklegged tick, Ixodes scapularis, a biological vector of human pathogens including Borrelia burgdorferi (the bacteria causing Lyme disease), is undergoing rapid and persistent expansion into Canada, exposing new human populations to zoonotic diseases. Here, we used an ensembled forecasting approach to construct niche models of I. scapularis' current and future distribution and to identify the environmental drivers of habitat range. Georeferenced occurrence points were acquired from community science programs (eTick and iNaturalist) between 2017 and 2022 in Canada and the United States. We also collected high-resolution environmental data using a spacing of approximately 1 km. We carried out 4704 model iterations across two datasets, 12 algorithms, and 10 climate profiles using 40 environmental variables. We extrapolated select models over three time periods, 2011-2040, 2041-2070, and 2071-2100, across two projected climate scenarios, SSP5-8.5 and SSP3-7.0, incorporating 2094 future outcomes of I. scapularis distribution. Our ensembles (AUC: 0.9565 ± 0.0065; TSS: 0.8435 ± 0.0155; Kappa: 0.819 ± 0.014) identified temperature, precipitation, biomass production (NPP), length of the growing season, climate moisture index, and number of yearly degree days as the variables that best explained I. scapularis distribution. Further changes to these climate conditions will result in continued I. scapularis range expansion, with, at the highest estimate, an increased niche area of ~248% (447,532 km[2] to 1,556,760 km[2]) and, at the lowest estimate, by ~205% (409,475 km[2] to 1,247,689 km[2]) before the turn of the century. These distributional niche changes coincide with a northern latitude limit reaching as far as ~48° N by 2040, ~50° N by 2070, and ~52° N by 2100. These findings highlight the invasive potential of I. scapularis, with implications for public health and changing ecosystem dynamics.

Assessing the impact of climate change on habitat dynamics of Hovenia dulcis in China using the MaxEnt model.

Frontiers in plant science, 16:1641811.

INTRODUCTION: Hovenia dulcis Thunberg, a multifunctional medicinal plant native to East and Southeast Asia, has been introduced worldwide. However, the environmental factors that determine its habitat and its precise distribution in China remain incompletely characterized.

METHODS: Therefore, the Maximum Entropy (MaxEnt) model integrated with, ArcGIS was employed to predict the potential distribution of H. dulcis in China, using 479 initial occurrence records (which were spatially filtered to 191 points) and 33 environmental variables (of which 15 were selected for the final analysis). Model performance was assessed via AUC-ROC, with key variables identified through permutation importance and response curves. Future projections were made under SSP126 and SSP585 scenarios for the 2050s and 2090s.

RESULTS: The model demonstrated high accuracy (AUC = 0.934). The distribution of H. dulcis was primarily governed by annual precipitation (Bio12), the minimum temperature of the coldest month (Bio06), elevation, and the mean diurnal temperature range (Bio02). The optimal ranges for these variables were as follows: annual precipitation of 708.5-2,956.8 mm, a minimum temperature of the coldest month between -4.9 and 8.9 °C, elevation of 273.9-1,019.4 m, and a mean diurnal temperature range of 6.81-10.18 °C. At present, suitable habitats are concentrated in central and southwestern China. Future projections indicate a northward shift and altitudinal increase in suitable areas, with expansions in Beijing, Hebei, and Liaoning, but contractions in Guangxi and Shandong. Hunan, Jiangxi, Sichuan, and Guizhou remain core suitable regions. This northward shift is consistent with preference of H. dulcis for the warm temperatures and adequate humidity, highlighting both its vulnerability and its adaptive potential under global warming.

DISCUSSION: H. dulcis is highly sensitive to climatic variables, particularly temperature and precipitation. Our findings provide a scientific basis for developing well-targeted conservation strategies, promoting sustainable utilization, and optimizing cultivation practices for H. dulcis under climate change.

Predicting the potential suitable habitats of invasive species in the Bidens genus in China under climate change.

Ying yong sheng tai xue bao = The journal of applied ecology, 36(10):3115-3125.

The distribution patterns of invasive species under climate change have become a key focus in ecology. In view of the strong invasive potential of the genus Bidens, we used the maximum entropy (MaxEnt) model to compare the range of suitable habitats for six Bidens species listed in the Chinese Invasive Species Information System (namely Bidens frondosa, B. alba, B. pilosa, B. vulgata, B. bipinnata and B. subalternans) under current and four different future climatic conditions. Results showed that the MaxEnt model could effectively predict the range of the suitable habitats of all the six species. Under current climate condition, the values of the area under the receiver operating characteristic curve of the six Bidens species are 0.929, 0.976, 0.921, 0.977, 0.903, and 0.980, respectively, indicating that these species have different suitable habitats. Under the four future emission pathways, although the overall area of suitable habitats for these six species generally will increase compared to the current scenario, some species exhibit fluctuating trends with the decreases in the area of suitable habitats. In summary, under global climate change, the suitable habitat ranges of these six invasive species of the genus Bidens generally will show an increasing trend. To effectively control those invasive species, further research should focus on the physiological traits of different species and their response to climate change.

Responses of radial growth of Populus cathayana to climate change in the western Sichuan Plateau, China.

Ying yong sheng tai xue bao = The journal of applied ecology, 36(10):3033-3042.

In the context of global warming, we investigated the growth dynamics and climatic response mechanisms of Populus cathayana in the Jiuzhaigou region, western Sichuan Plateau, an endemic broadleaf species in China. We developed a standardized tree-ring width chronology to analyze radial growth response to climatic factors from 1959 to 2022. Moving correlation analysis was applied to assess the stability of climate-growth relationships, and growth change percentage (PGC) method was used to identify growth release and suppression events. The results showed that the tree-ring width of P. cathayana was significantly positively correlated with May-June average maximum temperature (r=0.525), mean temperature (r=0.548), and average minimum temperature (r=0.341), but significantly negatively correlated with precipitation (r=-0.260), relative humidity (r=-0.579), and cloud cover (r=-0.483) during the same period. PGC analysis revealed three significant growth release events (1937-1940, average PGC=32.8%; 1977-1978, average PGC=42.2%; 1999-2004, average PGC=43.3%) and one significant growth suppression event (2008-2010, average PGC=-28.9%). Moving correlation analysis revealed a marked shift in climate-growth relationship during the 1970s, characterized by the transition of growing-season temperatures from negative to significantly positive, while relative humidity and self-calibrated Palmer drought severity index correlations shifted from positive to significantly negative. These findings underscore the non-stationary climatic responses of P. cathayana in western Sichuan, suggesting that warmer and drier conditions in the growing season favor the radial growth.

Impact of urbanization and climate change on underground temperatures: a modelling study in Milan (Italy).

Philosophical transactions. Series A, Mathematical, physical, and engineering sciences, 383(2308):20250038.

This study investigates the long-term evolution of the subsurface urban heat island (SUHI) effect in Milan, integrating historical records, present observations and future climate projections through a coupled fluid-flow and heat-transport numerical model. A N-S cross-section through the city serves as the domain for this study and boundary conditions were derived from historical maps starting in 1884, long-term air temperature time series starting in 1700, and distributed land surface temperatures from Landsat 8 satellite remote sensing. The research quantifies the temperature variations in the shallow subsurface over the past 150 years (1875-2025), calibrating the model against groundwater temperature measurements, and predicts trends up to 2100. Current estimates indicate urban temperature anomalies up to +5°C at the water table depth, and an expansion of the SUHI along the two-dimensional cross-section from 3 km in 1884 to 9 km in 2025. The findings highlight the heterogeneous distribution of subsurface temperature anomalies, influenced by variations in the groundwater depth, flow patterns, land cover and urban and infrastructure expansion. Future projections suggest a further increase in subsurface temperatures, particularly in areas with shallow groundwater. These results underscore the need to incorporate mitigation strategies into urban planning and policies, such as sustainable urban cooling measures and optimized geothermal energy utilization.This article is part of the theme issue 'Urban heat spreading above and below ground'.

Current and projected effects of climate change in cryosphere microbial ecosystems.

Nature reviews. Microbiology [Epub ahead of print].

Cold environments, including glaciers, ice sheets, permafrost soils and sea ice, are common across the surface of the Earth. Despite the challenges of life at subzero temperatures, the global cryosphere hosts diverse microbial communities that support biogeochemical cycling and ecosystem functioning in areas where few other organisms can survive. However, the composition and function of cryosphere microbial communities, and the continued existence of cryosphere habitats, are threatened by ongoing climate change, which has disproportionate impacts in polar regions. In this Review, we survey the breadth of cryosphere habitats and the composition, function and unique adaptations of the microbial communities that inhabit them. We outline how climate change can affect these communities and the ecosystem services they provide through short-term changes in substrate availability, enzyme activity and redox potentials as well as longer-term changes in community composition. We also explore the wide-ranging consequences these changes may have for local ecosystems, human communities and the global climate. Finally, we outline the knowledge gaps in cryosphere microbial ecology that contribute to uncertainties about the future of these ecosystems in a warming world.

Psychological interventions that decrease psychological distance or challenge system justification increase motivation to exert effort to mitigate climate change.

Communications psychology, 3(1):148.

Climate change is one of the biggest challenges facing humanity. To limit its damaging impacts, billions of people must take pro-environmental actions. However, these often require effort and people avoid effort. It is vital to identify psychological interventions that increase willingness to exert effort. 3055 people from six diverse countries completed an effort-based decision-making task (Pro-Environmental Effort Task; Bulgaria: n = 404, Greece: n = 85, Nigeria: n = 660, Sweden: n = 1090, UK: n = 482, USA: n = 334). Participants chose whether to exert physical effort (50-95% of their maximum) to reduce carbon emissions, after experiencing one of 11 expert crowd-sourced interventions or no intervention. We applied computational modelling to precisely quantify motivation to help the climate, compared to a closely matched non-environmental cause. We found two interventions, which reduced the psychological distance to climate change impacts or promoted climate action as patriotic and protecting participants' way of life, had consistent positive effects on increasing effortful pro-environmental behaviours, across measures and control analyses. At the individual level, motivation to benefit the climate was associated with belief in climate change and support for pro-environmental policies. In contrast, trait apathy and effort aversion were linked with reduced motivation to benefit both the climate and food cause. Together, our results have crucial implications for promoting effortful actions that help mitigate climate change.

A rapidly closing window for coral persistence under global warming.

Nature communications, 16(1):9704.

Coral reefs around the world are increasingly threatened by marine heatwaves causing widespread coral bleaching and mortality. Global analyses of projected heatwaves can inform decision-making, but forecasting the interactions between disturbance refugia, coral life histories and capacity to adapt is key for guiding strategic management of coral persistence. Here, we simulate coral eco-evolutionary dynamics across 3800 reefs of Australia's Great Barrier Reef under current climate projections. We project a rapid coral decline by mid-century under all emission scenarios, with further decline under the most likely warming trajectory. However, recovery is possible this century if warming remains below 2 °C, allowing thermal adaptation to keep pace. Our simulations show that resilient reefs are primarily in bleaching refugia, which also support a greater diversity of thermal phenotypes. While cool-adapted corals disperse to warm spots, we found no evidence of 'gene swamping' undermining thermal adaptation. Our findings highlight that management opportunities exist to promote adaptation in thermal refugia and warm spots, but emphasize that curbing global warming by 2050 is crucial for coral persistence.

Shifting dominant periods in extreme climate impacts under global warming.

Nature communications, 16(1):9746.

Spatio-temporal patterns of extreme climate events have been extensively studied, yet two questions remain underexplored: Do such events occur regularly, and how do regularity patterns change under global warming? We address these questions by investigating dominant periods in crop failure, heatwave, and wildfire data. Here, we show that under pre-industrial conditions dominant periods emerge in 28% of cropland exposed to crop failure and 10% of wildfire-affected areas, likely related to climatic oscillations such as the El Niño-Southern Oscillation, while heatwaves occur irregularly. The number of dominant periods increases by 2-13% during the transition from the pre-industrial era to the anthropocene. In the anthropocene, the occurrence of extreme events shifts towards monotonic growth, replacing previous natural regularity patterns. Linearly de-trended projections reveal an additional shift towards smaller dominant periods due to climate change. These shifts in regularity are crucial for adaptation planning, and our method offers an additional approach for studying extreme events.

Genetic diversity of Cebuella Gray, 1866 (Primates, Callitrichinae) from the western Amazonia lowlands and predictions of climate change impacts on its distribution.

Folia primatologica; international journal of primatology [Epub ahead of print].

Brazil, a country with a rich diversity of primates, faces the challenge of preserving these species, since most are at some level of threat of extinction. Among Brazilian primates, the pygmy marmosets (Cebuella niveiventris and C. pygmaea) stand out as the smallest known species of monkey, with a wide distribution in the western Amazon. Faced with the need for quick and well-founded information to guide conservation, recent studies have used analyses of Species Distribution Models (SDMs) for primates. The present study aimed to investigate the genetic diversity in Cebuella, using the mitochondrial gene cytochrome b, and analyze the potential distribution (SDMs) of the two species. The phylogeny showed Cebuella divided into two clades, corresponding to the two species of the genus, corroborating previous findings. Herein, we applied species delimitation tests to the genus Cebuella for the first time, revealing significant divergences. The bPTP method identified six probable species within Cebuella, while the ABGD indicated 15 putative species. Both methods point to a high diversity within the genus. Species suitability modeling suggested that C. niveiventris seems to be more sensitive to seasonal variations in rainfall (BIO15) and the amount of rainfall during the wettest quarter (BIO8), while C. pygmaea appears more impacted by the intensity of the early rainy season (BIO15) and a period of lower rainfall variability throughout the rest of the year. The most pessimistic scenario for the future suggested that the more intense the environmental changes resulting from human activities, the greater the impact on future climates, increasing the probability of population decline.

Projected Expansion and Northwestern Shift of Wikstroemia indica Suitable Habitats in China Under Multiple Climate Change Scenarios: An Optimized MaxEnt Approach.

Ecology and evolution, 15(11):e72448.

This study assesses the impact of climate change on the potential distribution of the traditional Chinese medicinal plant Wikstroemia indica, employing an optimized maximum entropy (MaxEnt) model for the first time for this species under multiple climate scenarios. Our analysis, based on 902 occurrence records and key environmental variables, provides clear evidence that climate change will significantly alter its distribution pattern. The results demonstrated that annual mean temperature (69.4% contribution) and mean diurnal temperature range (12.6% contribution) were the principal climatic factors affecting the distribution of W. indica. Under current climatic conditions, the total potential suitable habitat area for W. indica in China was calculated to be 153.31 × 10[4] km[2], accounting for 15.97% of China's land area. Projections indicate significant habitat expansion under future climate scenarios: under the SSP1-2.6 scenario, the total suitable habitat area would increase by 32.0% to 202.42 × 10[4] km[2] by the 2090s; under the SSP5-8.5 scenario, suitable habitat was anticipated to expand by 49.6% to 229.39 × 10[4] km[2]. Furthermore, the distribution centroid of W. indica was predicted to shift 76.68-119.91 km northwestward by the 2050s. The key message is that W. indica demonstrates considerable resilience to climate change, with its suitable habitat expected to expand and shift northwestward. This quantitative prediction, based on robust modeling evidence, provides critical insights for future conservation planning, sustainable management, and utilization strategies for this important medicinal resource in the context of global environmental change.

Climate change anxiety among young women living in the urban slums of Kampala, Uganda: findings from the baseline assessment of the TOPOWA cohort study.

BMJ public health, 3(2):e002439.

INTRODUCTION: Climate change is an emerging global health crisis, particularly in low-resource settings like Uganda's urban slums. These areas face significant challenges in mitigating climate risks, exacerbating the vulnerability of residents. This study aims to assess the prevalence of climate change anxiety and its association with generalised anxiety among young women living in urban slums. Understanding this relationship is crucial for developing community-based mental health strategies and resilience-building initiatives to address the psychological impact of climate change.

METHODS: This study utilises baseline data from 'The Onward Project On Wellbeing and Adversity' (TOPOWA), a prospective cohort study focused on mental illness and social determinants of health among young women aged 18-24 years living in Kampala's urban slums. A total of 300 women were recruited from three sites: Banda, Bwaise and Makindye. At baseline, interviewer-administered surveys measured climate change anxiety using the 13-item Climate Anxiety Scale and generalised anxiety using a 7-item scale. Bivariate and multivariate analyses were conducted to determine the associations between climate anxiety, generalised anxiety and demographic factors.

RESULTS: Of the 249 women included in the analysis, 21% reported moderate to severe levels of climate change anxiety, while the remaining 79% experienced mild to minimal levels. Multivariate analysis revealed a strong association between higher levels of generalised anxiety and increased climate change anxiety. Additionally, older age was linked to higher climate anxiety, whereas higher education levels and living in multigenerational households were associated with lower levels of climate anxiety.

CONCLUSION: One in five young women in Kampala's urban slums experiences moderate to severe climate change anxiety, closely linked to generalised anxiety. These findings highlight the urgent need for targeted mental health interventions and community-based resilience programmes. Leveraging family support in multigenerational households may also play a role in reducing climate-related anxiety and fostering adaptive coping mechanisms.

Investigating health professionals' understanding and risk perception of the effect of climate change on health. A cross-sectional study at three hospitals in Sunyani, Ghana.

Journal of public health research, 14(4):22799036251388592.

BACKGROUND: The study investigated health professionals' understanding and risk perception of climate change in the Sunyani Municipality by focusing on health professional's knowledge on climate change, examining health professional's risk perception of climate change on health and identifying the co-benefits of climate change mitigation.

METHODS: This quantitative oriented cross-sectional study randomly selected 400 health professionals across the Regional Hospital, SDA Hospital and Municipal Hospital as respondents. Quantitative data was analyzed using SPSS Version 25.

RESULTS: From the study, the results indicate that Health professionals are fully aware of the concept of climate change. Health professionals do not have knowledge pertaining to the scientific aspects of climate change. There was a statistical relationship between respondent's perception that climate change can lead to death (p < 0.001) and their awareness of the risk of climate change impact on health. There was a general likelihood of an increase in malaria (Mean = 2.98), Dengue fever (Mean = 3.16), Cholera (Mean = 3.18), schistosomiasis (Mean = 3.27), Meningococcal meningitis (Mean = 3.85) and Influenza (Mean = 3.73) due to climate change. These actions positively affect health and climate and they include: Giving up red meat (Mean = 3.21), Walking and cycling instead of using cars (Mean = 3.27), Reducing rural-urban migration (Mean = 3.46), Reducing air pollution from emission of fossil fuel (Mean = 3.63). A majority of 65% of respondents agreed to the incorporation of climate change related course work into nursing/medical school curricula as a policy to mitigate climate change.

CONCLUSIONS: The study concludes that health professionals are fully aware about climate change but lack a thorough understanding of the scientific aspects of climate change. The general risk perception of health professionals towards climate change impact on health was high. Climate change mitigation is beneficial to human populations.

Context dependency of maintenance communities of invasive parasites under climate change: a case study of mussels and intestinal copepods in the Wadden Sea.

Journal of the Royal Society, Interface, 22(232):20250370.

Climate change can impact the persistence of native and invasive parasites and their effects on hosts. Given the complexity of interactions in natural systems, models based on parasite-host systems can be helpful to explore long-term impacts. We investigate how two intestinal parasitic copepods impact host populations, and how the predicted temperature increase by year [Formula: see text] may affect the persistence and impacts of the parasites. We study Mytilicola intestinalis (a specialist established in blue mussels, Mytilus edulis) and Mytilicola orientalis (a recent invader infecting mussels and Pacific oysters, Magallana gigas) in the Wadden Sea. The parasites are non-lethal but can influence host maturation and fecundity. Using a mathematical model parametrized with empirical, field and literature data, we explore how temperature increase affects parasite basic reproduction numbers and the long-term population trends of parasites and mussels. Temperature increase reduces mussel populations below the critical community size for M. intestinalis persistence, while allowing M. orientalis to persist without oysters. M. orientalis does not have a negative effect on the host population in additional to that of M. intestinalis when both are present. We show that environmental change can have qualitatively different effects on related parasites by changing the role of the shared host as a maintenance population.

Addressing climate change and environmental sustainability in pharmacy: pharmacists' perceptions, training, and behaviours.

The International journal of pharmacy practice pii:8313942 [Epub ahead of print].

OBJECTIVES: To assess training, perceptions, and behaviours of pharmacy professionals and trainees about the relationship between climate change, environmental sustainability, and pharmacy practice.

METHODS: We conducted a cross-sectional survey-based study of a global sample of pharmacy professionals and trainees. Participants were recruited between June 2023 to March 2024 using professional networks and a snowball sampling approach. Descriptive statistics and content analysis were used to analyse survey results.

KEY FINDINGS: Four-hundred forty participants representing 24 countries responded to the survey. Participants identified as pharmacists, pharmacy students, or postgraduate pharmacy trainees practicing in a variety of settings. A majority reported substantial worry about the health impacts of climate change and had no prior training related to climate change. One-third of respondents indicated that pharmacists should address climate change and environmental issues. Many identified some action taken in their professional role. Barriers towards further action included lack of knowledge, time, and resources.

CONCLUSIONS: Pharmacy professionals and trainees globally are concerned about the health impacts from climate change and the environment. Further resources, support, and education are needed to support pharmacists in caring for patients experiencing climate-health impacts and in connecting with other health professionals doing this critical work.

Equipping future climate and health advocates: piloting a locally focused health effects of climate change curriculum in providence county schools.

BMC public health, 25(1):3784.

BACKGROUND: Climate change poses significant risks to human health, particularly for future generations, making it imperative to integrate climate education into school curricula. This study evaluates the feasibility of expanding the Health Effects of Climate Change Curriculum (HECCC) from Baltimore, MD, to urban youth in Providence County, Rhode Island. Developed by the Lung Health Ambassadors Programme (LHAP) at Johns Hopkins University, the HECCC is an interdisciplinary curriculum aimed at educating students on the health impacts of climate change and empowering them to take local action.

METHODS: During the 2023-2024 school year, the HECCC was adapted and piloted in five public schools in Providence County. The curriculum consisted of four lessons: climate science, air quality and heat, food and water, and health equity and environmental justice. Each lesson series discussed mental health impacts and was tailored to meet the unique needs of the participating schools, including a variety of delivery methods, with some schools integrating the curriculum into regular class hours and others as an after-school programme. Evaluation metrics included student reach, engagement, pre-and post survey results, and problem driven iterative adaptation (PDIA).

RESULTS: The HECCC was taught to 195 students from fourth through twelfth grades in Providence County schools. Students demonstrated engagement via non-verbal cues (e.g. smiling, nodding) and asked questions throughout the lessons. Based on preliminary pilot pre- and post-survey results from students (N = 10) and teachers (N = 3), the curriculum potentially increased students' knowledge of climate change, health impacts, and environmental justice, as well as their self-efficacy in addressing these issues. However, the surveys also potentially revealed an increase in students' climate anxiety. Results from teachers' surveys preliminarily indicated teachers' improved confidence in discussing climate change with students, but noted students' barriers to taking meaningful action, such as limited resources and time.

CONCLUSION: This study demonstrates the feasibility of implementing a locally curated HECCC in an urban setting. The study elicited teacher recommendations for further expansion, broader language translations, alignment with local state standards, and increased survey participation, especially to evaluate impact on eco-anxiety. Future plans involve expanding educator resources such as an educator's toolkit to facilitate the curriculum's adaptation in other communities, especially in alignment with local state standards. Overall, the HECCC shows promise in fostering climate and health literacy among urban youth, equipping them to be informed advocates for local environmental justice.

Climate change and malaria: an old enemy of Africa is back.

BMC public health, 25(1):3774.

BACKGROUND: Malaria is one of the deadliest transmissible diseases in Sub-Saharan Africa. The control of malaria is hindered by socio-economic and environmental factors and its growth is also associated with climate change, particularly temperature increases combined with precipitations and humidity.

OBJECTIVES: This study aims to analyse the trends of malaria in the last two decades and assess the influences of climate change on the transmission of malaria in Africa.

METHODS: Malaria incidence and evolution trends were used to evaluate the current burden of malaria in Africa. The Pearson correlation coefficient, joinpoint regression and linear regression models were applied to identify significant temporal shifts in malaria incidence trends across the selected countries and determine the impact of climate change on the transmission of malaria.

RESULTS: Our findings reveal that mean temperature is the main climatic factor affecting the transmission of malaria in many countries, including Angola, Cameroon, Ivory Coast, Ghana, Mozambique, and Uganda. Warmer temperatures generally increase the risk of malaria transmission, except in Ghana, where higher temperatures are associated with a decreased risk. Precipitation has a significant negative association with malaria incidence in Burkina Faso and Uganda, indicating that increased rainfall reduces transmission.

CONCLUSIONS: The study results provide useful insights on how climate change influences malaria in African countries, and reiterates the need for a greater engagement of policymakers and social partners, in intensifying the action needed to fight the transmission of malaria in Sub-Sahara Africa.

Mortality Related to Climate Change and Environmental Hazards in the Mediterranean Region: A Scoping Review.

Current environmental health reports, 12(1):41.

PURPOSE OF REVIEW: This scoping review aimed to map the scientific literature on mortality related to climate change and environmental manifestations in the Mediterranean region, explore the different methodological approaches used, identify research gaps, and suggest future research directions. This scoping review was conducted following the Joanna Briggs Institute (JBI) recommendations and the Preferred Reporting Items for Scoping Reviews (PRISMA-ScR). We included articles that examined the association between floods, wildfires, Saharan dust outbreaks, particulate matter (PM), urban heat islands (UHI), compound effects, and mortality.

RECENT FINDINGS: Most studies have been conducted in Euro-Mediterranean countries, with limited studies in the remaining Mediterranean countries. Regression analysis and descriptive designs predominated, while spatial and mixed-methods designs were less frequently used. Flood mortality rates were higher in northeastern Spain, southern France, and northern Italy. The primary cause of flood mortality was drowning, with a seasonal west-east gradient. Furthermore, lagged exposure to PM10 and PM2.5 from wildfires was associated with cardiovascular and respiratory mortality in most countries. Additionally, Saharan dust exposure was associated with total and respiratory mortality, especially during dust intrusion days. Likewise, Ozone exposure was principally associated with total and cardiovascular mortality. Furthermore, PM10 and ozone increased heat mortality when compounding in most of the studied Euro-Mediterranean cities. Our results showed substantial variability in mortality rates and causes associated with different climate change and environmental manifestations across the Mediterranean region. These findings highlight the urgent need for standardized and high-resolution mortality data to assess the health impacts of these hazards in understudied countries where health reporting is scarce.

Shifts in salamander body size associated with 60 years of climate change.

Proceedings. Biological sciences, 292(2058):20251319.

Climate change impacts body size, a fundamental trait central to energetics and reproductive success. Most studies on body size shifts in response to climate change have focused on temperature, with smaller sizes expected under warming. However, precipitation has received less attention, even though water and heat balance interact to impact body size. Precipitation changes may be particularly important for wet-skinned amphibians. We examined body size shifts in 10 plethodontid salamander species in the Balsam Mountains, Virginia, USA. Using historical data (1957-1959) as a baseline, we resurveyed salamanders (2021 and 2023) to assess how temperature and precipitation shifts have influenced body size. We hypothesized warmer, wetter conditions would reduce body sizes across species. Over 60 years, temperatures warmed across elevation, while precipitation increased more at higher compared to lower elevations. After accounting for phylogeny, warming generally reduced body size, with temperature effects amplified by increased precipitation at high elevations. However, the direction and magnitude of body size shifts were species-specific, indicating that size shifts are a complex interplay of environmental factors and species traits. Our findings highlight the importance of considering interacting climate variables when assessing responses to environmental change, particularly in montane ecosystems.

Human-Centric Disaster Resilience: Uncovering Social Inequity in Climate Change.

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

Understanding community disaster resilience is critical to mitigating the disproportionate impacts of climate change and natural disasters on socially vulnerable populations. However, despite extensive discussion on disaster resilience, a systematic analysis of the extent of social inequity across climate scenarios, geographic locations, spatial scales, and sociodemographic groups remains underexplored. Our study introduces a human-centric framework to investigate social inequities in community disaster resilience related to human well-being. We combined flood hazard maps under both historical and future SSP scenarios with a compound multilayer urban spatial network model consisting of roads, communities, and essential services to evaluate the residents' service resilience during flood events. Then, we utilized the Gini coefficient and Lorenz curve to quantify the degree of inequities in resilience among different sub-populations. With Central Chongqing as a case study, our analysis reveals a significant increase in both the number of affected communities and their vulnerability under future climate conditions. We further observed a striking spatial polarization in community resilience due to the islanding effect, whereby communities are increasingly divided into those with severely limited service availability and those with sufficient resources. In addition, we found that the extent of social inequity in resilience is highly spatial and scale-specific, with moderate levels of inequity at the city level, but the degree of inequity varies greatly across sociodemographic groups at a localized level. This widening socio-spatial differentiation may trigger widespread dissatisfaction in disadvantaged communities, hindering the collective disaster response actions and engagements to enhance community resilience. Our research highlights the importance of embedding future climate variabilities, human well-being, and social equity in inclusive disaster response policies, processes, and practices.

Tigers on the Move: The Impact of Climate Change on Tiger Distribution in Nepal.

Ecology and evolution, 15(11):e72397.

The Bengal tiger (Panthera tigris tigris), a flagship and umbrella species of the South Asian forest ecosystem, has declined dramatically in population and geographic distribution due to human-caused habitat fragmentation and poaching over the past century. Global tiger populations may persist in the next century only if the size and quality of the current habitat remain unchanged. Our first-of-its-kind study in Nepal assesses whether these habitat requirements are in place through an analysis of habitat suitability to predict the future habitat of tigers in varying climatic scenarios across the country. We collected tiger-presence location (GPS points) from tiger surveys conducted by the Department of National Parks and Wildlife Conservation, Nepal, in 2018 and 2022 across the country. We used MaxEnt software in varying Shared Socio-economic Pathways (SSP 245 and 585) employing eight bioclimatic and two topographic variables to predict the future habitats of the tiger in 2050, 2070, and 2090. In the SSP 245 scenario, tiger habitat could increase for all three time periods, but in the SSP 585 scenario, the habitat will increase only in 2050. Interestingly, in both scenarios, tiger habitat will increase by more than 80% in 2050. The expanded habitat in all scenarios is outside of protected areas and northeast of the current habitat. This indicates that extreme climate change scenarios with more industrialization, urbanization, and land use change have a greater impact on tiger habitat. Furthermore, tiger habitat qualitatively shifts from protected areas to outside protected areas in the human-dominated landscape. This creates more challenges for conservationists and managers as human-tiger interaction may surge. Proactive management solutions to protect Nepal's tigers for the next century could include expanding or establishing new protected areas, establishing connectivity and corridors between the tiger habitats, in addition to anticipatory efforts to address human-wildlife conflicts that will emerge in this changing landscape.

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).

Selected Bibliographies
