Deadly heat on planet Earth in 2100

Three-quarters of the world’s population will be exposed to deadly heatwaves by the year 2100 if greenhouse gas emissions continue to rise at the current rate.

This study was published this week in the journal Nature Climate Change and concludes that “74% of the world’s population will be exposed to deadly heatwaves by 2100 if greenhouse gas emissions continue to rise at current rates”.

“Even if emissions drop dramatically, it is likely that the percentage of human population affected will reach 48 percent”, according to the findings of a paper led by Professor of Geography at the Department of Social Sciences at the University of Hawaii in Manoa, Camilo Mora.

As far as heat waves are concerned, whose frequency is directly related to climate change, “we are running out of options for the future”, said the researcher, quoted in information released by the University. The evil and the terrible”.

Camilo Mora also recalled that humans around the world are now suffering from the effects of heat waves, and are predicted to continue, and “could be much worse if emissions are not significantly reduced”.

“About 30 percent of the world’s population is exposed to these deadly conditions each year”, scientists said.

The human body only works if it is at temperatures around 37 degrees, concludes the study. That is, “heat waves represent a considerable risk to human life since hot weather, aggravated by high humidity, can increase body temperature, thus leading to life-threatening conditions”.

The team led by Camilo Mora has already surveyed existing data and found 1,900 cases of places where high temperatures have killed since 1980 and, in addition to analyzing the climatic conditions of 783 other lethal episodes in 164 cities in 36 different countries, A limit has been identified from which temperatures and humidity become deadly.

The area of the planet where this threshold is exceeded by 20 or more days a year has been growing and is “estimated to increase even with cuts in greenhouse gas emissions,” the study finds.

“Actions like the withdrawal of the Paris Agreement (decided by the President of the United States, Donald Trump) are a step in the wrong direction that will inevitably delay the resolution of a problem for which there is simply no time to lose”, concluded Camilo Mora.
