The Hindu Kush Himalayan region, stretching for more than 2,000 miles, is home to the world's highest mountains. The mountain range is also home to the world's third-largest concentration of snow and ice, earning it the moniker the third pole; only the North and South Poles contain more. The glaciers of the Hindu Kush Himalayas are the main source of fresh water for around two billion people living in the region. However, by the end of this century, two-thirds of that snow and ice could be lost because of climate change. A network of data scientists and environmentalists around the world, and on the ground in the Hindu Kush Himalayas, are working to understand the extent of glacial melting in the Hindu Kush Himalayan region, its effects and what can be done to minimize its impact.
