The new evaluation warns that if the average temperature of the earth reaches 2 degrees than the industrial industry average, the extreme heat of the extreme heat of extreme heat to survive without artificial cooling can be too hot.
This paper is about 6%, which is about 6%, which is too hot to maintain a safe core body temperature even for healthy people between the ages of 18 and 60. In areas that threaten more than 60 vulnerable people will increase to about 35%of the earth.
paper It was just published In the journal Nature reviews the earth and the environment.
Last year, the global average temperature was the first year with a global average temperature of 1.5 degrees above the industry average. It was possible to reach 2 degrees from the current warming speed to the mid -21st century.
Tom Matthews, the chief author of King’s College London, said, “The thermal thresholds that are simply exceeded for the elderly in the most popular areas on Earth are likely to be seen in young adults. “Under such conditions, it is expected to cause fatal heat stroke even in long -term outdoor exposure, even in the shades of the mountain, even in a well -lived shade.”
This paper is based on prior work to “What if so?” “What if the worst future event was overhauled how hot and humid?” Sayed Radley HortonProfessor of Columbia Climate School and co -author of the paper.
Horton has co -written a 2017 thesis for predicting that potentially fatal heat and humidity combinations can start to rise in the late century, according to a 2020 study, according to a 2020 study, showing that it has already popped out in a short time.
For their evaluation, the team has linked physical climate science to the risk of losing mortality through scientific discovery. This analysis has seen a “unparentable” threshold in which the human core body temperature rises to an incomprehensible control and the core temperature increases to 42 ℃ within 6 hours.
Between 1994 and 2023, the compensation, which makes the human body unable to cope with the combination of temperature and humidity, has violated about 2%of the world’s land area of adults under 60 years old. More than 20% of the surface exceeded this threshold. For the elderly. Unlawful thresholds have been passed for all ages, but the unlucky threshold has been simply delivered to the elderly so far.
If the level reaches 4-5 degrees from the industrial industry, the elderly can experience the heat that cannot be compensated for about 60%of the land during extreme events. In this level of warming, the hard -to -live heat will also begin to appear as a threat to young adults in the most popular subtropical regions.
In certain areas, there is a risk of exceeding the thresholds that are not the most critical and unparalleled on the launch line with people in sub -Saharan Africa and South Asia.
Matthews said, “As more earth on Earth experiences an outdoor state that is too hot for our physiology, people should have accessibility to a cooler environment to the shelter from the above.
Since 2000, the most deadly ten incidents have been more than 260,000. Three deadly events in the 21st century caused almost 200,000 deaths, including about 72,000 people across Europe in 2003, 62,000 people across Europe in 2022, and in 2010, including Russian heat.
The study also participated in the University of California, Stanford University, NASA Godard Space Research Institute and Boston University.
It is applied in the press release of King’s College London.
