Data

Extreme weather events and trends studied for a human fingerprint (Carbon Brief map)

The number of extreme weather events and trends in Carbon Brief's map of attribution studies, which test whether human-caused climate change affected a specific extreme, as of the update of 19 March 2026. Studies cluster in Europe, East Asia and North America, so the map is not a sample of all extremes.
