Glaciers in Asia’s Hindu Kush Himalaya could lose up to 75% of their volume by the end of the century end due to global warming, causing both dangerous flooding and water shortages for the 240 million people who live in the mountainous region, according to a new report.

A team of international scientists has found that ice loss in the region, home to the famous peaks of Everest and K2, is speeding up. During the 2010s, the glaciers shed ice as much as 65% faster than they had in the preceding decade, according to the assessment by the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD), an intergovernmental scientific authority on the region.

"We’re losing the glaciers, and we’re losing them in 100 years’ time,” said Philippus Wester, an environmental scientist and ICIMOD fellow who was the lead author of the report.
