If global warming exceeds 2 degrees, 25 % of the Land will be “waterless”

More than a quarter of the planet’s surface will be considerably drier if global warming exceeds 2 degrees Celsius, according to a new study, reports Rus.Media. Such changes will cause increased threat of drought and forest fires. But limiting global warming to 1.5 degrees Celsius can significantly reduce the proportion of the surface of the Earth that undergoes these changes.

Bezwoda — measure for dryness the surface of the Earth that is calculated based on the amount of precipitation and evaporation. Bezwada is a serious threat, as it can critically affect agriculture, water quality and biodiversity. It can also lead to more drought and forest fires, similar to those now raging in California.

The research team examined forecasts 27 global climate models to determine areas where bezwoda will significantly change the climate, if global temperature rises by 1.5 and 2 degrees above pre-industrial levels.

Research suggests that bezvodnoye will come to 20-30% of the planet’s surface, when the increase of the average global temperature reaches 2 degrees Celsius. But two-thirds of the affected regions can avoid significant dehydration, if the warming will be limited to 1.5 degrees Celsius.

The world has already warmed by 1 degree. But the reduction in emissions of greenhouse gases in the atmosphere to keep global warming below 1.5-2 degrees Celsius, will reduce the probability of significant bezwoda, which manifests itself in many parts of the world.

The strength of droughts have increased throughout the Mediterranean, southern Africa and the East coast of Australia during the twentieth century. Palusalu regions of Mexico, Brazil, South Africa and Australia at some period of time faced with desertification.

Regions of the world that will receive the most benefits, if the temperature rise to contain 1.5 degrees South — Eastern Asia, southern Europe, South Africa, Central America and South Australia, where today is home to more than 20 % of the world population.
