Study: Physical Inactivity Due to Rising Heat to Kill 500K

Low- and middle-income countries face the steepest toll, with up to 700,000 additional premature deaths annually under high-emissions scenarios. Without serious climate action, the WHO's goal of cutting global inactivity by 15% by 2030 is dead on arrival.
