Climate Impact Lab Projects 451,000 Extra Heat Deaths From El Niño
Researchers say emergency heat measures could save tens of thousands of lives as the strongest El Niño on record drives 44% more extreme hot days.
- On Wednesday, September 23, 2026, the University of Chicago's Climate Impact Lab released a study projecting 451,000 excess heat-related deaths worldwide through February 2027 from the ongoing Super El Niño.
- Researchers describe this Super El Niño as a "postcard from the future," noting it mirrors conditions climate change will deliver in 20 years and will lead to 44% more extremely hot days than a typical year.
- Developing regions face the heaviest burden, with the Sahel projected to see 66,800 additional deaths, including 31,400 in Nigeria, while Southeast Asia faces 19,400 deaths, India 15,800, and Brazil 13,300.
- Climate Impact Lab co-founder Michael Greenstone noted that "emergency actions can be taken now" to save tens of thousands of lives through heat-warning systems, cooling centers, and anticipatory financing.
- Elevated heat-related mortality may persist beyond February 2027, particularly in India and Pakistan during their summer months, requiring emergency planning to extend into mid-2027 to address prolonged seasonal heat.
