Climate Change Drives 23% Rise in Heat-Related Deaths, Lancet Report Warns
The 2025 Lancet Countdown report finds heat-related deaths rose 23% since the 1990s to 546,000 annually, with fossil fuel reliance and adaptation delays worsening health and economic losses.
- A Europe-focused study presented on October 28, 2025, by economist Sigrid Stagl projects climate inaction could cost the continent up to 956 billion euros by 2050, according to the report.
- The Lancet Countdown found continued fossil fuel reliance and delayed adaptation harm health, with 13 of 20 indicators at unprecedented levels, while oil and gas giants expand production three times beyond a liveable planet's support.
- The Lancet Countdown authors report 154,000 wildfire‑pollution deaths in 2024 and $1 trillion in lost labour productivity, indicating severe health and economic impacts.
- Without action, Europe's annual climate-related health costs could exceed $950 billion and cause 30,000–80,000 extra heat deaths each year, the study warns, straining health systems and budgets.
- Ahead of COP30 in Belem, Brazil, researchers say Europe must invest roughly three times current levels, as doing nothing costs about six times more than needed decarbonisation investments.
