Rapid changes in the region’s climate, however, are affecting glacier flows and snowmelt. Local people are already modifying their land-use practices in response to the changing supply, and the region’s ecology is transforming. Scientists estimate that by 2100, these glaciers could be up to 75% smaller in volume.
NASA’s satellites observe and measure snow and ice cover remotely with multiple types of sensors. This allows scientists to create an authoritative estimate of the water budget of this region and a set of products local policy makers can use in responding to hazards and planning for a changing water supply.
