High Temperatures and Lack of AC Can Be Deadly

The world is experiencing unprecedented heat, with the average surface temperature recently reaching a record 17.15 degrees Celsius for two consecutive days. While air conditioning is a proven solution to mitigate heat-related health risks, it remains financially out of reach for many low-income families in Africa and Asia, who endure some of the hottest climates on the planet. The reliance on air conditioning, however, contributes to environmental challenges, as it releases hot air into the atmosphere, exacerbating urban heat and creating a cycle of increased demand. In developed nations, air conditioning is often viewed as a standard comfort, with over 90% of U.S. households equipped with units. In contrast, the global south faces stark disparities, where access to cooling technology is limited. Experts warn that extreme heat poses severe health risks, particularly for vulnerable populations, including those with pre-existing heart conditions. The consequences of heat stress are evident, with thousands of heat-related deaths reported annually in countries like the UK and the U.S. The disparity in air conditioning access perpetuates economic inequalities, making it increasingly difficult for low-income households to escape poverty. Projections indicate that by 2050, temperatures will frequently exceed 35 degrees Celsius in approximately 970 cities, predominantly in Asia, Africa, and North America. Alarmingly, while 80% of the wealthiest households are expected to have air conditioning by that time, only 2% to 23% of the poorest households will have similar access, highlighting a growing divide in climate resilience.
