Simon Lewis, a professor at University College London, warns that extreme hot flashes are now much more probable and emphasized that areas are being created in certain parts of the planet where it is impossible to survive due to the high temperature. He also explained the concept of "wet bulb" temperature.
The climate crisis has brought summer with increasingly dangerous heat, Lewis stated in the text "Canada is a warning: More and more parts of the world will soon become too warm for life", which was published in the British "Guardian", reports Sputnik.
Temperatures reached a shocking 47.9 degrees in British Columbia in Canada and caused more than 100 deaths across the country and North America. The heat wave raised the temperature to 50 degrees in five countries in the Middle East in June, and in Pakistan, 20 children ended up in hospital due to heat stroke.
Additional warming due to greenhouse gas emissions means that such extreme waves are now more likely and scientists can calculate an increase in their probability.
As an example, the professor stated that the European hot wave from 2019, which killed 2,500 people, was five times more probable then than it would have been before global warming.
In most places, extreme heat waves will create problems, from economic disruptions to widespread mortality, especially among young and old, Lewis pointed out.
He warned, as Sputnik reports, that in some places in the Middle East and Asia, something really frightening is appearing - areas are being created where it is impossible to survive due to the high temperature.
As he explained, although people can survive temperatures of more than 50 degrees when the humidity is low, when both temperatures and humidity are high, neither sweating nor bathing can help keep the body cool.
The so-called the temperature of the "wet bulb", which is shown by a thermometer covered with a wet cloth, and which measures the temperature at which the organism cools down due to sweating or watering. People cannot survive long-term exposure to "wet bulb" temperatures above 35 degrees, because there is no way to cool the body - neither in the cold, nor with unlimited water, he added.
It was once thought that a "wet bulb" temperature of 35 degrees was impossible, but scientists reported last year that some places in the Persian Gulf and Pakistan's Indus Valley have already reached that threshold, albeit only for an hour or two, and only at small surfaces.
As temperatures are rising due to climate change, it is predicted that in the coming decades, the heat and accompanying temperatures that cannot be survived will last longer and occur in larger areas and new places, including parts of Africa and the southeastern United States, he said.
