| Many of Asia's glaciers are retreating as a result of climate change. This retreat impacts water supplies to millions of people, increases the likelihood of outburst floods that threaten life and property in nearby areas, and contributes to sea-level rise. The U.S. Geological Survey, in collaboration with 39 international scientists, published a report on the status of glaciers throughout all of Asia, including Russia, China, India, Nepal, Bhutan, Pakistan, Afghanistan, Georgia, Kyrgyzstan, Tajikistan, and Kazakhstan. "Of particular interest are the Himalaya, where glacier behavior impacts the quality of life of tens of millions of people," said USGS scientist Jane Ferrigno. "Glaciers in the Himalaya are a major source of fresh water and supply meltwater to all of the rivers in northern India." As glaciers become smaller, water runoff decreases, which is especially important during the dry season when other water sources are limited. Climate change also brings warmer temperatures and earlier water runoff from glaciers, and this combined with spring and summer rains can result in flood conditions. The overall glacier retreat and additional melt can increase the amount of water dammed in the vicinity of a glacier, and the added pressure enhances the likelihood of disastrous outburst flooding. |
