World Weather Attribution, a scientific group that monitors extreme weather, has released a report investigating 67 extreme temperature events from May 2024-May 2025. The report presents two major findings:
1) "4 billion people — about 49% of the global population — experienced at least 30 additional days of extreme heat (hotter than 90% of temperatures observed in their local area over the 1991-2020 period) due to human-caused climate change."
2) "In 195 countries/territories, climate change at least doubled the number of extreme heat days, as compared to a world without climate change."
