Scientists from Princeton University said that humans in the tropics may begin to die out due to
The researchers combined data from 22 climatemodels, writes Naked Science. They studied how quickly wet-bulb temperatures (TW) would reach 35 degrees Celsius in the tropics. And this is an important indicator for human survival. 35 degrees Celsius is a critical value at which human skin stops losing heat.
Scientists have seen that when the average annual temperature rises by 1.5 degrees Celsius, in the tropics the temperature will reach 35 degrees for more than three hours a day.
This will negatively affect people and cause many health problems and even premature death.
