"The Northern Hemisphere's summers of 2023, 2024 and 2025 were the three hottest on record, climate agencies in the European Union and the U.S. have announced. This record summer heat was driven primarily by human-caused climate change, which not only has been raising average global temperatures but also has been fueling more lethal heat waves. A new study released on Wednesday finds that climate change likely tripled the number of heat-related deaths in European cities this summer."
"Many of these [people] would not have died without climate change, said study co-author Friederike Otto, a climate scientist at Imperial College London, during a press conference about the finding. The June-to-August period of 2025 was the third hottest on record, with a global average temperature 0.47 degree Celsius (0.85 degree Fahrenheit) above the 19912000 average, according to the European Union's Copernicus Climate Change Service (C3S)."

Climate change likely tripled the number of heat-related deaths in European cities during summer 2025, with many people who would not have died without climate change. The June-to-August period of 2025 had a global average temperature 0.47 degree Celsius above the 19912000 average, according to Copernicus. NOAA measured the Northern Hemisphere summer as 1.02 degrees C warmer than the 20th-century average and ranked the year-to-date as the second warmest behind 2024. Early 2025 featured a weak La Niña, which tends to cool global temperatures.
