High temperatures likely to cause deaths and will worsen in future as global heating intensifies, scientists warn
The dangerous 32C heat that will be endured by people in the south-east of England on Saturday will have been made 100 times more likely by the climate crisis, scientists have calculated.
Global heating, caused by the burning of fossil fuels, is making every heatwave more likely and more intense. The 32C (89.6F) day forecast on Saturday would have been expected only once every 2,500 years without the climate crisis, the researchers said, and June heatwaves are now about 2-4C (3.6-7.2F) hotter than in the past.
The heat is expected to cause premature deaths, particularly among older and vulnerable people. More than 10,000 people died before their time in summer heatwaves between 2020 and 2024, according to the UK Health Security Agency, and the UK government has been heavily criticised for failing to properly prepare people for extreme weather.
Prolonged heat is especially dangerous as it gives no time for people’s bodies to cool off. Maximum temperatures in the south-east are expected to be above 28C for three consecutive days. The scientists said this heatwave was made 10 times more likely by the climate crisis.
