The report highlights that the southern hemisphere, including regions like Africa, Indonesia, and Brazil, will experience the most immediate impacts, with Nigeria alone potentially seeing over 30,000 additional deaths in the next six months. India and Pakistan are also expected to face severe consequences. Vulnerable groups, such as the elderly and infants, are particularly at risk. Beyond heat-related deaths, El Niño could exacerbate other hazards, including wildfires, infectious diseases, and flooding, further increasing the potential death toll.
