Detailed explanation-1: -Most of the freshwater lakes are in the Himalayan region. They are of glacial origin. They are formed when glaciers dug out a basin, which was later filled with snow melt.
Detailed explanation-2: -Atmospheric warming is the main driver of glacier melt in the Hindu Kush Himalayas-temperatures here, as at the poles, are rising faster than the global average. But local topography and other factors may also be shaping the pace of retreat, scientists say.
Detailed explanation-3: -Melting glaciers have significant impact on water resources of Himalayan rivers due to change in glacier basin hydrology, downstream water budget, impact on hydropower plants due to variation in discharge, flash flood and sedimentation.
