Europe is experiencing a deadly heatwave with new June temperature records set in the U.K. and France. Human-caused climate change has made this extreme heat virtually impossible compared to 50 years ago. Heat warnings are widespread across the continent, with the heatwave expected to spread over the next two weeks. Spain has reported at least 212 heat-related deaths, Italy five, and France recorded 40 drowning deaths linked to unsupervised swimming. France also faces a high risk of wildfires due to drought conditions. A significant percentage of European cities are already experiencing or predicted to break their highest heat stress levels. Overnight temperatures are about 100 times more likely now than during the 2003 heatwave, and daytime peaks are about 10 times more likely. France recorded its hottest night and day on record this week, with one town experiencing the hottest day ever recorded in the country. The U.K. also provisionally set new June temperature records for consecutive days. Scientists comparing current weather with cooler climates of the past found this week's heat would have been significantly cooler without climate change. The research confirms heatwaves are becoming hotter, more frequent, and longer-lasting due to climate change.
