What this story says

  • A Stanford University study found older adults face dangerous heat at temperatures 4.7 to 7.5°C lower than younger people can tolerate.
  • If global warming reaches 1.5°C, 22% of people over 60, about 290 million, will be exposed to unsafe heat for at least a month each year.
  • Each additional degree of warming will expose roughly another billion people to an extra month of intolerable heat, with the greatest risks in India, Pakistan and Bangladesh.
  • Most heat-related deaths occur indoors, increasing the need for cooling access in vulnerable regions.

A study led by Stanford University researchers found that older adults are far more vulnerable to heat than previously estimated. The research, published in *The Lancet Planetary Health* on 18 August 2026, used new data from wet-bulb experiments conducted on people over 60 in the U.S. to model heat tolerance across age groups.

Previous studies relied on heat thresholds for young, healthy adults, which the Stanford team said underestimated risks for older people. The new modelling showed that at 1.5°C of warming above pre-industrial levels, 22% of people over 60, about 290 million, would face unsafe heat for at least a month each year. Young adults would not reach similar risk levels until warming reaches 4°C.

The study warned that uncompensable heat, where the body cannot cool itself, would become more frequent and widespread. Regions with high poverty and limited cooling access, including India, Pakistan, Bangladesh, Myanmar and Niger, face the greatest threats. The researchers also noted that most heat-related deaths occur indoors, making access to air-conditioning and cooling facilities critical.

What the coverage left out

None of the right-rated digests mentioned the study’s finding that most heat-related deaths occur indoors. The centre-rated digests largely omitted the study’s call for age-specific heat action plans, which was highlighted in ABC Australia’s full report. The left-rated digests did not include the study’s projection that at 3°C warming, elderly people in south Asia could face dangerous heat day and night for three months a year.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

5 rated outlets

  • The five left-rated digests led on the study’s finding that older adults face heat risks at much lower temperatures than previously thought. ABC Australia’s full report quoted lead author Qinqin Kong stating that older people’s heat tolerance was 4.7 to 7.5°C lower than young adults’, and that 22% of those over 60 would face unsafe heat at 1.5°C warming. The report also highlighted concerns for Australia’s hotter regions, such as the Top End and Kimberley.
  • Liberation’s digest emphasised the term “incompensable heat” and the 22% figure, while El Pais’s digest quoted the study’s warning that “many more people will be at risk.” The Indian Express’s digest focused on India, noting that older adults in Delhi and the Indo-Gangetic plain could face over 2,000 hours of intolerable heat annually at 3°C warming.

Centre

8 rated outlets

  • The eight centre-rated digests consistently led on the study’s finding that heat risks for older adults had been “dramatically underestimated.” CTV News’s full report quoted the study’s conclusion that intolerable heat would affect “far more people than previously estimated” and noted that at 3°C warming, elderly people in south Asia and the Gulf could face dangerous heat day and night for three months a year.
  • Le Télégramme’s digest highlighted the 22% figure, while Sud Ouest’s digest noted that humidity had been underestimated as a factor for older adults. The Japan Times’s digest pointed out that earlier research did not account for older people sweating less or having weaker hearts. Most centre-rated digests included the study’s warning about climate migration driven by uncompensable heat.

Right

6 rated outlets

  • The two right-rated digests, from the Bangkok Post and Free Malaysia Today, led on the study’s finding that heat risks for older adults had been underestimated. Both included the 22% figure for people over 60 facing unsafe heat at 1.5°C warming. Neither digest mentioned the study’s warnings about climate migration or the specific vulnerabilities of regions like south Asia.

Questions about this coverage

How did the left and right cover Stanford study: Older adults face heat risk at lower temperatures than…?
Of the 19 outlets on this story carrying a published leaning rating, 29% are rated left, 47% are rated centre, 24% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 33. The sections above set out what each side emphasised, in its own terms.
Is Stanford study: Older adults face heat risk at lower temperatures than… left or right?
Neither side dominates it. Of the 19 rated outlets on this story, 29% are rated left, 47% are rated centre, 24% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Stanford study: Older adults face heat risk at lower temperatures than… biased?
Stanford study: Older adults face heat risk at lower temperatures than estimated is one event reported by 33 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered Stanford study: Older adults face heat risk at lower temperatures than…?
33 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
How much lower is heat tolerance for older adults compared to younger people?
The Stanford study found that people over 60 can no longer maintain a stable core temperature at temperatures 4.7 to 7.5°C lower than young adults. This means older adults face dangerous heat stress at much lower thresholds than previously estimated.
How many older adults will face unsafe heat if warming reaches 1.5°C?
The study estimated that 22% of people over 60, about 290 million, will be exposed to unsafe heat for at least a month each year if global warming reaches 1.5°C above pre-industrial levels. This risk increases with each additional degree of warming.
Which regions face the greatest heat risks for older adults?
The study identified India, Pakistan, Bangladesh, Myanmar and Niger as the countries facing the greatest threats. These regions have high poverty levels and limited access to cooling, making older adults particularly vulnerable to uncompensable heat.
