High heat tripled deaths in Europe/ Climate change "took" the lives of

Human-caused climate change intensified Europe's recent heatwave and increased the number of heat-related deaths by around 1,500 in 12 European cities, a study by Imperial College London and the London School of Hygiene & Tropical Medicine has found.

Focusing on ten hot days from June 23 to July 2, the researchers estimated the number of deaths using peer-reviewed methods. They found that climate change almost tripled the number of heat-related deaths, with fossil fuel use increasing heatwave temperatures by up to 4°C across cities.

They warn that temperatures will continue to rise and the death toll in the future is likely to be higher, until the world largely stops burning oil, gas and coal and reaches net zero emissions.

This is the first rapid study to estimate the number of climate change-related deaths for a heatwave and was led by scientists at Imperial College London and the London School of Hygiene & Tropical Medicine.

Some of the most important findings of the study were:

About 1,500 of the 2,300 estimated heat-related deaths, or 65%, are the result of climate change increasing heat by 1-4°C, meaning the number of deaths tripled due to the burning of fossil fuels.

Climate change was the cause of 317 estimated deaths from high heat in Milan, 286 in Barcelona, 235 in Paris, 171 in London, 164 in Rome, 108 in Madrid, 96 in Athens, 47 in Budapest, 31 in Zagreb, 21 in Frankfurt, 21 in Lisbon and 6 in Sassari (Sardinia).

This means that the potential number of deaths from heat caused by climate change in many European cities was higher than other recent disasters, including the 2024 Valencia floods (224 deaths) and the 2021 floods in Northwestern Europe (243 deaths).

People aged 65 and over accounted for 88% of deaths, highlighting how those with underlying health conditions are more at risk of premature death in heatwaves.
