- Researchers logged 157 high-impact events in 2025, with heatwaves the deadliest and some now up to ten times more likely than a decade ago.
- Global temperatures remained unusually high despite La Niña conditions, underscoring the strength of the long-term warming trend.
- Major impacts spanned continents, including wildfires in Greece and Turkey, deadly floods in Mexico, Super Typhoon Fung-wong in the Philippines, and severe monsoon flooding and landslides in India.
