The Climate Impact Lab at the University of Chicago warns that the current super El Nino could lead to 451,000 additional heat-related deaths worldwide between June 2026 and February 2027. The report highlights a 44% increase in extremely hot days, with developing countries facing the greatest risk.
Nigeria, Indonesia, and Sudan are among the most vulnerable regions, with projections of 66,800, 19,300, and 15,800 additional deaths respectively. The study accounts for local climate and vulnerability factors, using data from 24,378 regions to estimate excess mortality.
The report urges immediate action, including heat warnings, cooling centers, and hydration stations, to mitigate the impact. Researchers emphasize the need for targeted emergency responses to save lives as the heatwave extends beyond the six-month period studied.
