According to a study conducted by the BBC, the number of days in many parts of the world with temperatures above 50° C has doubled since the 1980s.
The study was carried out by the BBC World Service under the title Life at 50° C. It said that between 1980 and 2009, on average, 14 days of temperature were 50° or more every year. However, the number of days that have exceeded exceptional temperatures since 2010 has now increased to 26.
BBC News examined the data over a 40-year period. It found that the total number of days above 50° C has increased in each decade since 1980. BBC research shows a significant increase in maximum temperatures around the world.
The number of days with a temperature of 50° Celsius was more in the Middle East and Gulf countries. Scientists expect that in the future, the temperature of more areas will exceed 50° Celsius. The study showed that the number of days with a temperature of 45° C also increased by an average of two weeks per year.
In the most recent decade, maximum temperatures on both land and sea have increased by 0.5 °C compared to the long-term average from 1980 to 2009. In Eastern Europe, South Africa, Brazil, the temperature rose by 1° Celsius, while the Middle East saw a rise of 2° Celsius.
Dr Friederick Otto, a leading climate scientist at the University of Oxford, told the BBC that he believes an increase in days and places above 50° C could be 100% attributable to the burning of fossil fuels.
Extreme heat can increase disasters such as wildfires and droughts and have devastating consequences on human health. High temperatures promote evaporation from the soil. Therefore, it can also dry up the land. Rising temperatures can cause many parts of the planet to become so hot that this place will no longer be habitable for people.
By 2100, heatwaves could affect 1.2 billion people worldwide. According to the results of a Rutgers University study last year, if global warming continues at the same pace, the figure would be at least four times higher than those affected today.
