Researchers said they believe that human-driven climate change probably intensified the recent European heat wave and increased the number of heat-related deaths.

Human-induced climate change may have intensified the European heatwave between 23 June and 2 July 2025, and increased the number of heat-related deaths, according to a new rapid analysis.

Europe's latest spell of sizzling heat, which ended last week, caused a threefold rise in heat-related deaths because human-induced climate change boosted the intensity of the heat wave, British scientists said.
