In brief
- Researchers estimate that excess heat caused more than 50,000 deaths in European urban areas during summer 2026.
- The study attributes nearly two thirds of the estimated heat deaths to human-caused climate change.
- The research covered 854 urban areas and found a higher toll than in 2003 or 2022.
- Germany recorded around 16,000 heat deaths, while Malta, Italy and Hungary had the highest mortality rates.
- New reports describe summer 2026 as the highest heat death toll on record, while earlier reports differed on the historical comparison.

New coverage calls summer toll highest on record
BMJ ↗Malta, Italy and Hungary record highest heat death rates
Guardian Health ↗Germany's estimated heat death toll reaches around 16,000
DIE WELT ↗Study across 854 urban areas exceeds earlier summer tolls
Le Monde ↗Climate change linked to two thirds of deaths
nu.nl ↗Peer-reviewed estimates put urban heat deaths near 50,000
NYT Climate ↗How it started
Europe experienced several heatwaves during the summer of 2026, according to The Independent. New research now estimates that around 50,000 people died from heat across the continent's cities, NYT Climate reported.
The estimates concern deaths linked to heat, not simply the temperatures reached. Le Monde reported that the study covered 854 urban areas and was conducted by two British institutions.
How it unfolded
On October 22, NYT Climate reported new peer-reviewed estimates describing the summer as Europe's deadliest for heat by far this century. CNN put the estimated toll across European cities at more than 50,000.
The same day, nu.nl reported that roughly two thirds of the estimated deaths were attributable to climate change. That finding links a large share of the mortality to climate change rather than treating the entire toll as its consequence.
On October 23, Le Monde reported that the heatwaves had been much deadlier in the cities studied than those of 2003 or 2022. DIE ZEIT reported that most deaths were in southern and western Europe.
Country-level reporting showed different measures of the burden. DIE WELT reported around 16,000 heat deaths in Germany. Guardian Health reported the highest death rates in Malta, Italy and Hungary, with health problems, loneliness and poverty worsening the toll.
Where it stands
The death toll remains a research estimate. Reports differ in how broadly they describe the record: NYT Climate called it a likely record and the deadliest summer for heat this century, while DIE WELT described it as the deadliest since records began.
The city-based scope also matters. Le Monde identifies 854 urban areas as the study's coverage, so the headline estimate should not be read as a complete count of heat deaths in every European community.
