Over 1 billion people may suffer due to the growing global temperature, if it climbs up by at least 2 degrees Celsius. The respective research was published by British meteorological service during the COP26 summit in Glasgow, wrote The Guardian.
"The Met Office assessed wet-bulb temperature, which combines both heat and humidity. Once this measure reaches 35C, the human body cannot cool itself by sweating and even healthy people sitting in the shade will die within six hours. The Met Office analysis used a wet-bulb temperature limit of 32C, at which workers must rest regularly to avoid heat exhaustion, for at least 10 days a year. If efforts to end the climate emergency fail and temperatures rise by 4C, half of the world’s population will suffer from this extreme heat stress", the article reads.
According to the latest studies, the level of heat has grown threefold over the last decades. In summer 2020, more than a quarter of U.S. population suffered consequences of severe heat, with such symptoms as nausea and cramps.
In 2018, scientists found out that the deadliest place on Earth in terms of extreme heat would be the North Chinese plains, one of the most inhabited regions in the world.
According to the WHO, some 166,000 people deceased from heat waves over two decades (prior to 2017).
