Regional Glacier recession: An indicator of global warming, a study of Kolahoi Glacier (Liddar Valley), Western Himalayas

Since the beginning of twentieth century, mountain glaciers have generally experienced worldwide retreat and thinning in response to ~0.74°C increase in global mean surface temperature. Consequently, additional fresh water is released from glacier storage that modifies current stream flow regimes. Water resources play a key role in the sustainable development of human activities and for preserving the ecological...
