A recent heatwave has led to an estimated 2,300 deaths in Europe, mostly linked to climate change, which has intensified extreme heat.

Analysis by researchers at Imperial College London shows that in the 10-day period ending July 2, the heatwave caused 2,300 deaths in 12 European cities. Of these, 1,500 were attributed to climate change, which increased temperatures by up to 4 degrees Celsius. June 2025 was the hottest in European history, and researchers warn that with climate change, heat waves will become more frequent and severe, affecting more and more people.
