Study estimates 50,391 European heat deaths
Researchers say climate change was responsible for about two-thirds of the modelled summer toll in 854 cities.
A new study estimates that 50,391 people died as a result of unusually high temperatures in European cities during the summer of 2026. The researchers say around 32,619 of those deaths were linked to additional heat caused by human-driven climate change.
The figures come from modelling of heat-related mortality in 854 European cities during June, July and August. According to the study, the researchers compared the estimated effect of observed temperatures with a modelled climate in which human-caused warming was absent or substantially reduced.
The study estimates that the climate-change contribution accounted for about 65% of the total. AP describes the number as a statistical estimate based on temperature, population and mortality relationships, rather than a direct count from death certificates.
The researchers said the estimate is likely to be conservative. According to the researchers, the analysis covered cities representing about 40% of Europe’s population and did not include a deadly heatwave in May. They said it also does not provide a complete assessment of deaths in rural areas.
The report described 2026 as the deadliest summer in its city dataset. According to the report, the previous highest estimate in the same research series was 29,480 heat-related deaths in 2022. The report placed Italy, France, Spain, Germany and the UK among the countries with the highest estimated totals.
The findings raise policy questions about greenhouse-gas emissions, heat-health plans, cooler buildings, tree cover and support for vulnerable people. The study estimates risk across populations; it does not determine an individual’s cause of death or predict what will happen in any particular household.

One story, several perspectives
What is established
- Researchers modelled heat-related mortality in 854 European cities.
- The study attributes a substantial proportion of the estimate to human-caused warming.
- The analysis has geographic and seasonal limitations.
Left
Arguments The estimate is evidence for faster emissions cuts and stronger public protection, especially for poorer and older people who face unequal exposure.
Values Climate justice, prevention and collective responsibility.
Consequences Delayed action would increase avoidable deaths and adaptation costs.
Centre
Arguments Governments need both emissions reduction and practical adaptation, with spending prioritised by evidence about where risk is greatest.
Values Public health, proportionality and institutional competence.
Consequences A combined strategy could reduce immediate harm while addressing long-term warming.
Right
Arguments The model should not be used to justify sweeping restrictions without transparent evidence; adaptation and resilience may deliver more immediate protection.
Values Proportionate policy, local decision-making and economic freedom.
Consequences A focus on adaptation may protect people quickly, but could leave the underlying warming trend less addressed.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

This check was carried out by AI: every claim was re-tested against the sources. Even an approved article can contain errors — stay critical.
The article clearly labels the mortality figures as modelled estimates and preserves the study’s stated limitations. It does not turn the estimate into a claim about individual patients.

Editor's note
The death toll is a modelled estimate, not a register of individually confirmed deaths. The parliamentary response confirms the headline estimate but is not independent scientific validation.Sources
