☀️ Rising Heat Could Cause Up To 700,000 Extra Deaths A Year By 2050 A study in The Lancet Global Health finds that higher temperatures may push more people into inactivity, increasing health risks. Each extra month above 27.8°C is linked to a 1.4 percentage-point rise in inactivity worldwide (1.85 pp in lower-income countries). By 2050, this could lead to 470,000–700,000 extra deaths annually and $2.4–3.68 billion in lost productivity.
