Earth could get too hot for humans

Scientists at Purdue University and the University of New South Wales calculated the highest possible “wet bulb” temperature that humans can withstand and found that this temperature could be exceeded in future climate scenarios.

“Wet bulb” temperature is meant to simulate what is felt by wet skin when it meets moving air, taking into account measures such as humidity. In order for a person’s cooling process to work, the surrounding air must be cooler than the skin, which must be cooler than the person’s core body temperature.

If “wet-bulb” temperature is warmer than the skin, metabolic heat cannot be released by the body, which can lead to heat stress.
