Scientists say Europe's heatwave 'impossible' without climate change

scienceJun 26, 2026865,274

World Weather Attribution scientists found the current western Europe heatwave is the most severe and widespread on record and would have been virtually impossible without human-driven climate change from fossil fuel burning. The study says high humidity during the event is producing exceptional heat stress, with almost half of Europe’s 850 largest cities experiencing their worst ever heat-stress conditions. Researchers note that temperatures now would have been about 2C cooler in 2003 and about 3.5C cooler in 1976, making such an event far less likely in those years. The UN’s climate chief said the crisis is caused by burning coal, oil and gas and urged a faster shift to clean energy and stronger resilience measures. National impacts include heat-related deaths in France and widespread forecasts for new national records in countries such as Germany, where some model runs predicted cities reaching about 42C. Scientists warn that continuing emissions at current rates lock in more frequent and more extreme heatwaves for the future.

The heatwave in western Europe is the most severe and widespread ever, with almost half of Europe’s largest cities experiencing their worst ever heat stress, a combination of high temperatures and humidity. Unless we stop burning fossil fuels, future heat conditions will become even more extreme.
