Gangotri Glacier Decline:
A recent study (IIT Indore, ICIMOD, US universities) reconstructed the hydrological discharge of the Gangotri Glacier System (GGS), showing shifts in meltwater trends due to climate change. The Gangotri Glacier System (GGS) is a major source of the Bhagirathi River, a key tributary of the Ganga. Comprises Gangotri, Chaturangi, Raktavaran, and Meru glaciers; ~549 km² area, ~48% glacierised. Earlier peak discharge → risk of water scarcity in late summer/autumn for downstream communities. Leads to Greater flood vulnerability in July with intense monsoon rains.
