Glacier Loss Raises High Concern Over Water Supplies

LONDON, 2 June, 2015The glaciers of the Everest region of the Himalayan massifhome to the highest peak of allcould lose between 70% and 99% of their volume as a result of global warming.
Asias mountain ranges contain the greatest thickness of ice beyond the polar regions. But new research predicts that, by 2100, the worlds highest waterson which billions of people depend for their water supplycould be at their lowest ebb because of the ice loss.
Many of the continents great rivers begin up in the snows, fed by melting ice in high-peak regions such as the Hindu Kush, the Pamir and the Himalayas.
Joseph Shea, a glacial hydrologist at the International Centre for Integrated Mountain Development in Kathmandu, Nepal, and French and Dutch colleagues report in The Cryosphere journal that they used more than 50 years of climate data and sophisticated computer models of predicted climate change to study the pattern of snowpack and seasonal melt in the Everest region.
Temperature increase
They found a decrease of 20% since 1961, and signs that most, if not quite all, of the stored ice could disappear in the next 85 years.
