The Impact of Climate Change on Human Health and Pharmaceuticals
Published: 2026-02-16
Subjects: Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Public Health, Environmental Sciences, Medical Sciences, Medicine and Health Sciences, Pharmacology, Toxicology and Environmental Health, Public Health, Sustainability, Toxicology
Climate change and air pollution affect nearly every major organ system, altering both the presentation of disease and patient responses to pharmaceutical treatments. However, existing knowledge on how patients, healthcare professionals, and governments should prepare for these challenges is fragmented. Climate change contributes to premature mortality, increased morbidity, and exacerbation of [...]
MACROM: An Optimal Control Model for Balancing Climate Change Abatement and Damage Trade-offs
Published: 2026-02-12
Subjects: Applied Mathematics, Climate, Environmental Indicators and Impact Assessment
The current pace of global emissions reduction is inadequate to meet the Paris Agreement temperature target of 1.5°C. While carbon dioxide removal (CDR) is increasingly viewed as necessary to meet these targets, questions remain about the optimal scale and timing of deployment when both costs and climate damages are considered. Here we present MACROM, an optimal control climate-economic model [...]
Global Climate Risks for Outdoor Sports Under CMIP6 Scenarios: A Multi-Indicator Assessment Based on WBGT, Heat Index, Heavy Rainfall, and Heatwaves
Published: 2026-02-03
Subjects: Environmental Indicators and Impact Assessment, Physiology
Outdoor sports are increasingly exposed to climatic conditions that challenge athlete safety, performance and event organisation. Despite extensive physiological and epidemiological evidence on heat stress, no global assessment has yet quantified how multiple climate hazards will jointly constrain outdoor sport under future climate change. Here we provide the first global, CMIP6-based, [...]
Hybrid Physics–AI Ecosystem Simulations Improve Biogeochemical Predictions in Temperate Shelf Seas

Subjects: Artificial Intelligence and Robotics, Biochemistry, Biogeochemistry, Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Marine Biology, Numerical Analysis and Scientific Computing, Oceanography, Planetary Biogeochemistry, Terrestrial and Aquatic Ecology
Biogeochemical models form a core part of marine forecasting and climate projections, yet they suffer from persistent biases in predicting key ecosystem variables, creating challenges across regional and global scales. To address this, we developed an AI-augmented three-dimensional hybrid framework that integrates machine-learning corrections directly into a process-based model’s productivity [...]
Evidence of low watershed resilience across the Western United States
Published: 2026-01-16
Subjects: Environmental Indicators and Impact Assessment, Environmental Monitoring, Sustainability, Water Resource Management
Vulnerable waters, including headwater streams and non-floodplain wetlands, are essential to watershed level resilience but notoriously difficult to measure over large spatial scales. Although individually small, vulnerable waters as a whole are integral in regulating hydrologic and biogeochemical processes. In the relatively small proportion of vulnerable waters that are continuously monitored, [...]
Assessing the Impact of Wind Erosion in Baringo County, Kenya
Published: 2026-01-13
Subjects: Environmental Indicators and Impact Assessment, Geomorphology, Soil Science
Wind erosion poses substantial threats to soil health and agricultural productivity in arid and semi-arid environments globally. In response to the escalating environmental challenge of wind erosion, this study, centered in Baringo County, employs a blend of remote sensing and GIS techniques alongside the Revised Wind Erosion Equation (RWEQ) model. The study spans a 25-year period, with a main [...]
Facilitating AI-Driven Sustainability: A Service-Oriented Ar-chitecture for Interoperable Environmental Data Access
Published: 2026-01-13
Subjects: Artificial Intelligence and Robotics, Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Meteorology, Software Engineering, Sustainability
Advances in Artificial Intelligence (AI), particularly agentic AI, have created opportunities to enhance global sustainability by improving the efficiency and accuracy of environmental monitoring and response systems. Agentic AIs autonomously plan and execute towards specific goals with minimal or no human intervention; however, accessing environmental data is challenging and requires expertise, [...]
Governing the cryosphere beyond political timeframes
Published: 2025-11-26
Subjects: Climate, Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Sciences, Environmental Studies, Glaciology, Nature and Society Relations, Oceanography and Atmospheric Sciences and Meteorology, Sustainability
Cryospheric systems are nearing irreversible thresholds, yet political processes remain misaligned with the long timescales of ice loss. Using COP30 as context, we argue that cryosphere science must inform governance capable of linking near-term decisions with long-term stability in a rapidly changing world.
Coral reef commitments are largely absent from national biodiversity and climate frameworks
Published: 2025-11-21
Subjects: Biodiversity, Climate, Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Marine Biology, Natural Resource Economics, Natural Resources and Conservation, Natural Resources Management and Policy, Oceanography, Other Oceanography and Atmospheric Sciences and Meteorology, Sustainability
Global agreements under the Convention on Biological Diversity (CBD) and the UN Framework Convention on Climate Change (UNFCCC) call for integrated action on biodiversity loss and climate change. Yet national implementation remains poorly understood, even for ecosystems highly vulnerable to warming, such as tropical coral reefs. Bleaching-level heat stress has affected over 85% of global reefs [...]
The Tocantins Framework: A Machine Learning-Based Assessment of Intra-urban Thermal Anomalies
Published: 2025-11-10
Subjects: Applied Statistics, Artificial Intelligence and Robotics, Computer Sciences, Environmental Indicators and Impact Assessment, Environmental Sciences, Statistics and Probability, Sustainability
The Urban Heat Island (UHI) effect has been extensively studied at the city scale. Yet, the Intra-Urban Heat Island and the Intra-Urban Cool Island effects remain poorly characterized due to the absence of standardized quantification frameworks. This study introduces the Tocantins Framework, a dual-metric system combining machine learning and spatial morphology to identify and quantify [...]
Factors Affecting Aboveground Carbon Storage in Mixed Oak-Pine Forests: A Multiple Regression Analysis of Southeastern U.S. Forest Inventory Data
