Overview
- World Weather Attribution cataloged 157 major disasters in 2025 across floods, heatwaves, storms, wildfires, droughts and cold spells.
- Of 22 events analyzed in detail, 17 were found more likely or more intense due to anthropogenic warming, while five extreme rainfalls showed no clear attribution signal.
- Modeling indicates the August wildfires in northwest Iberia were roughly 40 times more likely in today’s climate.
- January’s Los Angeles–area wildfires were assessed 35% more probable, with about 400 deaths and roughly $30 billion in insured losses reported.
- Hurricane Melissa’s October peak winds reached 288 km/h versus an estimated 270 km/h without warming, and recent U.S. winter storms caused three deaths in California and widespread New York flight cancellations, underscoring ongoing vulnerability.
