If the goals of the Paris Climate Agreement are not achieved, the consequences will be bitter
Even more than a quarter of Earth's surface will become significantly drought even if mankind can limit global warming to only two Celsius degrees. That number was precisely the goal agreed upon by the Paris Climate Agreement, scientists warned.
However, if the warming kept and restricted to 1.5 degrees, it could then limit the drying to the tenth, which would save two thirds of the Earth for which the drying is expected to be within the two-degree limit. It's all part of the research published in the journal Nature Climate Change.
Aridification or desecration is another way of transforming some desert regions, either by natural or anthropogenic influences. Of course, here are problematic increased anthropogenic activity or man's position in the ecosystem, which is what we can control, unlike natural factors.
Inspired by the "only" 1.5 degree sections of southern Europe, southern Africa, central America, the coasts of Australia and Southeast Asia – which makes the home about the fifth of humanity – "escape a lot of relaxation" predicted at 2 degrees Celsius, he explained Su -Jong Jeong of the University of Science and Technology in China's Shenzhen, or one of the authors of the study. "Achieving a 1.5 degree limit would be an important act of decreasing the likelihood of relieving and related consequences," concluded Jeong.
Jeong with a group of scientists used projections of seven climatic models through various warming scenarios to predict soil drying patterns.
Relaxation is a major threat that accelerates desertification and soil degradation and the loss of plants (especially trees) that are key to the absorption of carbon dioxide that warms the Earth. This multiplies the risks of fire and drought, and this also affects the quality of drinking water and agriculture.
Scientists have come to the conclusion that in the event of an overheating of this two-degree controversy, which could occur in the forecasts between 2052 and 2070, about 24 and 32 percent of the total Earth's soil would become drought.
However, if the warming would be 1.5 degrees, this effect could probably be reduced to 8 or 10 percent of the total surface.
