European countries report more than 10,000 excess deaths during the late-June heatwave, according to official monitoring data cited by multiple outlets. The figures are based on excess mortality—deaths above expected levels from all causes—during the period when temperatures peaked, commonly given as June 22 to 28, across parts of western Europe. A monitoring network called EuroMOMO pools national mortality data from 27 European countries and shows that more than 9,000 of the excess deaths are among people aged 65 and older. Some reports describe “very high” or “moderate” excess mortality in particular countries such as France and Belgium, while others report lower or normal excess. Several outlets also note that excess mortality totals may rise or shift as additional data are revised. Heat can increase deaths by causing heat stress and by worsening cardiovascular and respiratory conditions, and health agencies identify older adults as especially vulnerable. Scientific groups and attribution researchers quoted by outlets say the heatwave’s intensity and frequency are linked to human-caused climate change, with one attribution assessment stating the event would have been virtually impossible without climate change.
