The intensifying El Niño is expected to exacerbate heatwaves, wildfires, and other climate-related disasters globally. Vulnerable populations, particularly those in regions without adequate cooling infrastructure, face heightened health risks. South Korea has already issued warnings to halt outdoor activities due to dangerous heat levels. In Europe, wildfires have displaced thousands, while record-breaking temperatures threaten agriculture and water supplies. The U.S. is also experiencing unprecedented heat, with potential impacts on energy grids and public health. These conditions underscore the urgent need for climate resilience measures.
