A new study finds people aged 60 and over are at greater health risk from extreme heat than previously estimated, with harmful heat stress potentially occurring at lower global warming levels. The research, published in *The Lancet Public Health*, indicates that older adults may face unsafe conditions even when the world warms only modestly above preindustrial levels.
The study links rising temperatures to longer and more frequent sustained extreme-heat spells. One outlet reports that at about 1.5°C of warming above preindustrial levels, a substantial share of people over 60 could experience unsafe heat for extended periods each year. Another outlet emphasizes that older adults are likely to be disproportionately affected as global warming continues.
Across the coverage, the main differing emphasis is on framing: one source highlights the specific share of at-risk older adults at the 1.5°C threshold, while the other focuses on the broader public-health implication that heat dangers for seniors emerge sooner than earlier research suggested. Both describe a continuing rise in heat stress risk as warming increases.
