35,000 people in Europe have already died this summer due to extreme heat.

Omissions

• The 35,000 figure is a LOWER BOUND ('at least 35,000 excess deaths'), not a definitive count; the true toll is likely higher.
• The source metric is 'excess deaths during heatwaves' (deaths above the normally expected level), which is broader than deaths certified as directly caused by heat; the claim presents it as deaths 'due to extreme heat'.
• The figure is a preliminary/rapid estimate, not a consolidated official statistic; final official mortality counts typically take months to publish.
• Other concurrent estimates differ in scope and magnitude: an England & Wales study (LSHTM) estimated >2,700 heat-related deaths in May–June 2026, and Le Monde reported ~14,000 heat-related deaths in Germany and 4,458 in Spain this summer — figures that are consistent with, but not identical to, a Europe-wide 35,000 total.
• Only journalistic (secondary) sources were located for the exact 35,000 figure; the underlying study itself (primary source) was not retrieved within the search budget, so the exact figure rests on a single underlying study reported by the press.
• The exact 35,000 Europe-wide figure was found only in sources published 2026-08-20 to 2026-08-25, i.e. shortly before the 2026-09-15 session date; no official Eurostat/national statistics office consolidated count was found.
