Super El Niño Could Cause 451,000 Heat…Super El Niño Could Cause 451,000 Heat Deaths

The University of Chicago Climate Impact Lab projects roughly 450,000 excess heat-related deaths worldwide associated with the current El Niño, with estimates extending into early 2027. The projections combine temperature forecasts with historical relationships between heat and mortality; Africa and parts of Asia are identified as particularly exposed. Researchers and experts stress that the figures are uncertain and point to heat warnings, health outreach, cooling facilities and worker protections as ways to reduce harm.
