How South Asia Can Adapt to Extreme Heat

Last year was the hottest the earth has ever experienced. There has been little sign of high temperatures abating; 2025 began with the hottest January on record. Climate change has doubled the number of days of extreme heat in 195 countries and territories, according to new research by Climate Central and the Red Cross Red Crescent Climate Centre. In April 2024, Munshiganj in Southwest Bangladesh experienced a 100-year heatwave. Even under the most optimistic projections, such events will be exceeded in the future, on average, once every 6 years.

Despite the clear need for urgent action to combat the growing threat posed by rising temperatures, we remain inert. Investment, research and implementation to address the dangers of extreme heat must ramp up if we are to avoid loss of life. Southwest Asia, South Asia, and Eastern China are among the regions most prone to extreme heat.

Extreme heat is measured via “wet-bulb temperatures,” a combined measure of temperature and humidity. In these regions, the wet-bulb temperature may reach 35 degrees Celsius, or 95 degrees Fahrenheit, if global climate change is not sufficiently mitigated. At this temperature, even the fittest human body can no longer cool itself through sweating, if such conditions extend for hours.
