Older Adults Face Expanded Heat Exposure as Global Warming Rises
New Lancet Planetary Health study shows that accounting for age-specific heat tolerance could more than double global exposure to dangerous heat, threatening hundreds of millions of older adults (60+) as warming rises from 1.5°C to 4°C; at 1.5°C roughly 290 million seniors would face 180+ hours of dangerous heat annually, underscoring the need for age-targeted adaptation as the 60+ population grows to about 2.1 billion by 2050 and many live in heat-prone regions.
