- A preliminary estimate suggests Europe's most extreme heatwave killed between 17,000 and 25,000 people.
- The estimate used a statistical model based on past temperature-mortality data, projecting approximately 20,390 deaths during 22-28 June 2026.
- Official counts, like the WHO's report of over 1300 excess deaths, are lower due to incomplete data and delays in reporting.
- Some experts argue the model may overestimate deaths, citing improved adaptation and seasonal timing factors, proposing a lower figure around 15,000.
- Heat is highlighted as the deadliest weather hazard, with preventable deaths calling for urgent adaptation measures in health and infrastructure systems.
