The 35,000 figure found in the sources refers to excess deaths during Europe's summer 2026 heatwaves (reported August 2026), described as an 'at least' floor estimate, not to a full calendar-year 2025 total as the phrase 'in the last year' suggests.
At least one report notes the 35,000 excess deaths were recorded across 'barely half the continent', so geographic coverage is partial rather than all of Europe.
Other widely cited estimates give substantially different magnitudes for different periods/metrics: 62,700 heat-related deaths in summer 2024 (ISGlobal/Nature Medicine); ~16,500 climate-change-attributable deaths in summer 2025 across 854 cities (LSHTM); and about 175,000 heat-related deaths per year in Europe (UN/WMO), showing the figure depends heavily on the year and the metric chosen.
The supporting sources are news outlets (Guardian, China Daily and others) that appear to draw on the same underlying study/press release, so they are not fully independent corroboration, and no primary/official statistical source publishing the exact figure was located.
