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 deaths worldwide between now and February 2027. Michael Greenstone and Tamma Carleton were part of the research team along with Genevieve Maricle and Emily Grover-Kopec. They explain why Africa’s Sahel region is projected to be the hardest hit area, and why Nigeria is also projected to be one of the worst hit country. He explains what steps governments need to take now to protect people there.
