European heatwave kills 10,000, 90% aged 65+
Late-June scorcher caused 'unusual' spike in fatalities, data shows.
Official mortality tracking from the EuroMOMO network reveals that the late-June 2026 heatwave across Western Europe resulted in more than 10,000 excess deaths, the vast majority (over 9,000) among people aged 65 and above. The data, supported by the European Centre for Disease Prevention and Control and the World Health Organization, shows a 'really high' spike for that time of year, according to Lasse Vestergaard, Chief Physician at Denmark’s Statens Serum Institut. He noted that extreme heat is the only plausible explanation for such excess mortality, as it can cause heatstroke or worsen cardiovascular and respiratory conditions.
Scientists have attributed the intensity of this heatwave to human-caused climate change, stating it would have been 'virtually impossible' without it. The event underscores the growing vulnerability of older populations to extreme weather, with the majority of deaths occurring in people over 65. The findings highlight the urgent need for heatwave preparedness, early warning systems, and climate adaptation measures across Europe, especially as such events become more frequent and intense.
- 10,000+ excess deaths recorded in Western Europe during late June 2026 heatwave.
- Over 90% (9,000+) of victims were aged 65 or older, per EuroMOMO data.
- Heatwave 'virtually impossible' without climate change, scientists confirm.
Why It Matters
Climate-driven heatwaves are now a direct threat to elderly populations, demanding faster adaptation policies.
