Scientists project a 'Super El Niño' will push global temperatures 1.2°C above normal through spring 2027, resulting in approximately 451,000 heat-related deaths in the first nine months, with 239,000 deaths expected in the next six months alone. The Global South, particularly the Sahel region and Southeast Asia, will face the heaviest toll, with Nigeria, Sudan, Indonesia, and India among the most impacted countries.
