Glaciers in the Hindu Kush Himalaya are melting at unprecedented rates and could lose up to 75% of their volume in a century due to global warming. That could cause both dangerous flooding and water shortages for the people who live in the mountainous region, according to a new report.
“We’re losing the glaciers, and we’re losing them in 100 years’ time,” said the lead author of the report. At 1.5 degrees Celsius or 2C of warming above preindustrial temperatures, glaciers across the entire region will lose 30% to 50% of their volume by 2100. At 3C of warming, glaciers in the Himalaya will lose up to 75% of their ice, the report said.
The report found water flows in the region’s 12 river basins, including the Ganges, Indus, and Mekong, are likely to peak around mid-century. This will affect the more than 1.6 billion people who depend on this supply.
報告主要作者表示：「我們正在失去冰川，我們將在100 年後失去它們。」報告中說，如果未來溫度比工業化前高出攝氏1.5 度或2 度，2100年時，全區冰川將損失30％至50％；如果變暖3 度，喜馬拉雅山的冰川則會損失高達75％。
