Scientists urge WHO to declare climate change a global health emergency
Researchers call for the World Health Organization to label climate change a global health emergency, citing a Lancet Countdown study that attributes three million heat‑related deaths worldwide since the 2015 Paris Agreement, with 68 % directly linked to human‑caused warming. The report also notes a record 710,000 heat‑related deaths in 2023, over 70 % of which stem from climate change, and highlights a surge in extreme drought affecting 52 % of land in 2025. The study was released ahead of COP 31 in Turkiye.
