Summary

Researchers at the University of Chicago's Climate Impact Lab combined temperature forecasts with research on how heat affects death rates in more than 24,000 regions worldwide and found that the super El Niño could cause an estimated 451,000 additional heat-related deaths worldwide between now and February 2027. Michael Greenstone was part of the research team, along with Tamma Carleton, Genevieve Maricle and Emily Grover-Kopec. He explains why Africa's Sahel region is projected to be the hardest hit and why Nigeria is projected to be one of the worst-hit countries.
