A recently published research has suggested that about a quarter of whole world might be left in permanent drought if we fail to meet the goals to cut down global warming set by Paris agreement.
In order to find out the possible results of the global warming if unchecked, researchers compiled predictions of over 25 different climate models to determine which regions of Earth would be most affected. The results from the research revealed that between 20 and 30 percent of Earth will be significantly drier in the coming years.
Chang-Eui Park, a researcher at the the Southern University of Science and Technology in Shenzhen, China said. “Aridification is a serious threat because it can critically impact areas such as agriculture, water quality, and biodiversity. It can also lead to more droughts and wildfires — similar to those seen raging across California.”
During the research, scientists also looked at how the rise in temperature will ultimately affect the environment. While the current goal of the Paris agreement is to limit global warming to a 2 degree Celsius increase above Earth’s pre-industrial average, it might not be enough to reduce the drought. However, researchers found that limiting the global warming to less than 1.5 degrees would prevent most the aridification.
Tim Osborn, a professor at UEA said in a press release, “The areas of the world which would most benefit from keeping warming below 1.5 degree Celsius are parts of Southeast Asia, Southern Europe, Southern Africa, Central America and Southern Australia — where more than 20 percent of the world’s population live today.”
