Tropical isoprene variability differs across three regions
Study reveals tropical isoprene varies by region: Amazonia emission-controlled, Maritime Continent chemistry-controlled, and equatorial Africa intermediate, requiring region-specific atmospheric.
Neural network predicts shifts in extreme weather frequency
—
in MeteorologyNeural networks leverage climate model data to predict how extreme rainfall, hail, and winds will shift geographically as climate changes, accounting for terrain effects.
Climate ethics review finds justice and responsibility shape responses
Literature review examining ethical frameworks and justice principles shaping climate policy responses across governance scales from 1990-2025.
Aviation climate policies may not deliver full promised effects
Economic analysis examining policy mechanisms for aviation emission reduction, comparing domestic regulations and international agreements.
Croplands cool nights but have mixed daytime effects in tropical Africa
Cropland expansion across tropical Africa produces nighttime cooling but hydroclimatically-dependent daytime effects, driven by turbulent heat flux changes tied to vegetation differences.
Downscaled projections show stronger rainfall extremes in two Philippine basins
—
in ClimatologyHigh-resolution climate projections for Pampanga and Pasig-Marikina-Laguna-Lake basins reveal intensifying rainfall extremes, elevated design rainfall, and increased seasonal variability.
Landfalling South Pacific atmospheric rivers are projected to intensify
—
in MeteorologyStudy projects atmospheric river frequency to double over South Pacific by mid-century, with robust trends emerging within 10-20 years first affecting southern New Zealand and Tasmania.
Fire weather emergence is already detectable in many burnable areas
—
in ClimatologyClimate models show fire weather conditions driven by human warming already detectable in 39% of burnable areas, with dangerous extremes emerging at 2–3°C warming in multiple regions.
Moderate warming may still lead to extreme climate outcomes
—
in ClimatologyStudy shows extreme droughts, floods, and wildfires could occur at 2°C warming, exceeding impacts projected for 3-4°C. New sector-focused assessment reveals risks hidden by standard climate models.
Wildfire smoke PM2.5 caused estimated health and economic burdens in Canada
Analysis of wildfire-PM2.5 health impacts in Canada 2019-2023 quantifies premature mortality, respiratory outcomes, and economic costs ranging from billions annually.
