Carbon Brief

Mapped: How climate change affects extreme weather around the world

Carbon Brief's database of scientific studies that test whether human-caused climate change affected a specific extreme weather event or trend: 967 extremes from 819 studies published from 2004 to 2025. Each row gives the event or trend, its type (heat, rain and flooding, drought, storms, cold, wildfire and others), Carbon Brief's classification of the finding (more severe or more likely, less severe or less likely, no discernible human influence, or inconclusive), the study's citation, whether it was a rapid study, a link to the paper, a quoted summary sentence, and region and country codes. Studies cluster in Europe, East Asia and North America.
