Earth will have a lot more Sahara desert if this trend continues to happen

gradually because of the process - that trend will create a lot of unwanted disasters for humans. And one of them is the risk of land , which experts have been forced to issue warnings recently.

Specifically, according to Dr. Manoj Joshi from the Department of Environmental Sciences at the University of East Anglia, if the Earth rises only 2 ° C, a large part will become arid and gradually turn into desert, like the Sahara.

At that time, at least 1/4 of the area will be affected, ie 1.5 billion people will lose their inherent living environment.

The temperature rises, the desert will increase the area.

"The dry chemical ratio will increase to 20% - 30% of the current land area when the temperature increases by 2ºC" - said Dr Joshi.

Joshi's team calculated 27 climate models around the world, and identified the areas most prone to desertification. It is part of Southeast Asia, Southern Europe, South Africa, Central America and South Australia. With so many affected areas, at least 20% of the world's population cannot live peacefully. The figure is equivalent to 1.5 billion people.

Up to the present time, the Earth's temperature has increased by 1 ° C compared to the period of industrial revolution in the 20th century. According to Dr. Chang-Eui Park, co-author of research from China University of Science and Technology Country, this is a pretty serious threat.

The drying process seriously affects agriculture.

"The drying process is really a problem, because it seriously affects agriculture, water quality, and ecological diversity."

"It increases drought and forest fires, just like what's happening in California."

In 2015, countries around the world signed the Paris Agreement on the prevention of climate change, in order to show the co-operation to control human consequences. The immediate goal of the agreement is to prevent the rise in temperature of only 1.5 ° C, and it is now becoming more important than ever.

"With only 1.5 ° C, the area affected by the dry process will be greatly reduced," Jeong said.

The study is published in Nature Climate Change.
