The report highlights disproportionate impacts on developing nations, particularly in Africa's Sahel region and Southeast Asia. India is projected to experience 15,800 additional heat-related deaths, while countries like Nigeria, Indonesia, and Sudan are also expected to face severe consequences. Vulnerable populations in these regions are at heightened risk due to limited access to cooling systems, healthcare, and reliable water supplies. The cumulative exposure to elevated temperatures poses significant health risks, especially in areas with already high temperatures.
