Himalayan glaciers have been the subject of intense debate amid growing concern that melting ice could imperil a wide swath of South Asia that relies on groundwater from the “Third Pole.”
Scientists have struggled to improve their understanding of the glaciers’ fate using satellite data and limited ground measurements, bumping up against the limits of the region’s extreme topography and political barriers.
The picture that has emerged is complex, with wide variation among ice in the Himalayas, Hindu Kush and Tibetan Plateau. Studies suggest glaciers are stable or accumulating in the Karakoram Range on the Pakistan-China border. But in the eastern Himalayas and the Tibetan Plateau, they appear to be shrinking.
