El Niño heat deaths projected at 451,000 globally; Brazil 5th worst at 13,300

A University of Chicago climate laboratory report projects 451,000 heat-related deaths globally under El Niño conditions, with Brazil ranked 5th at 13,300 deaths, behind Nigeria, Indonesia, Sudan, and India. The projection is a model-based estimate, not an observed toll, and uncertainty surrounds the scenario assumptions. It underscores the human cost of climate-driven extreme heat, particularly in vulnerable tropical and low-income countries.
