Global warming will lead to an increase in deadly heat

Communications Earth & Environment: deadly heat will increase by the end of the century Scientists at Washington and Harvard Universities have found that global warming will lead to an increase in deadly heat by the end of the century.

This is reported in an article published in the journal Communications Earth & Environment.

The researchers examined data on the combination of temperature and humidity, expressed by a thermal index measuring the impact on the human body. For example, dangerous heat is determined by a temperature of 39.3 degrees Celsius, and extremely dangerous — 51 degrees Celsius, which exposes a person to significant stress for any period of time in such conditions. However, these standards were originally developed for people working in enclosed spaces, for example, in boiler rooms.

The last breath the scientists called the deadline for the death of all life on Earth. How exactly will this happen?On March 27, 2021, record temperatures are expected to become much more frequent in North America and Europe.

The situation will be more difficult in countries closer to the equator, where by 2100 it will become difficult to work outdoors for more than six months every year. This will happen even if humanity starts limiting emissions. If countries manage to achieve the Paris Agreement’s goal of keeping warming at two degrees Celsius above pre-industrial values, by 2100 heat exceeding the dangerous threshold will be 3-10 times more frequent in the United States, Western Europe, China and Japan. In the tropics, the number of dangerous days could double by 2100, covering half of the year.

In the worst-case scenario, if emissions remain uncontrolled until 2100, extremely dangerous conditions in which people should not be outdoors may become commonplace in countries closer to the equator, especially in India and sub-Saharan Africa.
