Over the next two decades , the world’s around two million glaciers have lost the equivalent of a about 25 miles thick layer of ice due to global warming. Some glaciers have also become shorter, while others have completely disappeared. Melting ice results in sea level rises, flooding, changes to ecosystems and disruption to hydroelectricity production. In the Asia mountain range in central Tien Shan , glacier retreat could also affect the water supply for around two million people within the next two decades . There is not much incentive, or money, to install improvements like drip irrigation that would save water and improve productivity. Ultimately, the great river basins of Asia , on which hundreds of millions rely, could also be affected.
