The report estimates thatclimate-driven temperature changes could contribute toapproximately 430,000 additional deaths every year by 2050compared with historical conditions, with poorer countries expected to suffer 10 times more deaths than wealthier nations. The findings reveal that access to electricity and cooling technologies, particularly air conditioning, will become a defining factor in climate resilience. While richer nations are projected to significantly expand cooling infrastructure, millions of people in low-income countries may remain trapped without reliable electricity, making them far more vulnerable to deadly heatwaves. Unequal Access to Cooling Drives Rising RisksThe report highlights that air conditioning has become one of the most effective tools for reducing heat-related illness and mortality. “Air conditioning is a lifesaver,” said Michael Greenstone, co-founder of the Climate Impact Lab and professor at the University of Chicago. However, he noted that many low-income nations lack the reliable and affordable electricity needed to expand cooling access as temperatures continue to rise. Researchers project thatelectricity demand for cooling will increaseseven times more in middle-income countriesthan in low-income nations because ofclimate change. In many poorer countries, the expected increase in electricity consumption per person would only be sufficient to power a single LED light bulb for approximately four months, illustrating the enormous gap in adaptation capacity.

Together, theseregions are projected to account foraround 377,000 heat-related deaths annually by 2050. Most affected countries include Niger, Mali, Burkina Faso, Chad, Pakistan, Bangladesh, Nepal, and Myanmar. The report comparesNigerandSaudi Arabia, noting that although both experience extreme heat, Saudi Arabia has significantly greater capacity to expand cooling infrastructure. By 2050, communities in Niger are projected to experience27,000 more climate-related deaths annuallythan those in Saudi Arabia.

According to Ashwin Rode, a fellow at the Climate Impact Lab, the study pinpoints communities most vulnerable to heat-related mortality because they lack access to cooling technologies. The report recommends several priority actions, including:Expanding reliable and affordable electricity accessDeveloping heat early warning systemsImplementing heat action plansStrengthening healthcare servicesIncreasing urban greening initiativesProviding targeted social protection programmesIt also argues that electricity market reforms should become a central part of national climate adaptation strategies.

As global temperatures continue to rise, unequal access to electricity, cooling technologies, healthcare, and climate adaptation measures could significantly widen existing disparities between wealthy and developing nations. The report concludes that strengthening energy infrastructure alongside public health planning will be essential to reducing heat-related deaths and building resilience in the world’s most vulnerable communities.
