India, Aug. 25 -- Climate change is reshaping the Gangotri Glacier System (GGS) - the source of the Ganga, according to a new study 'Hydrological Contributions of Snow and Glacier Melt from the Gangotri Glacier System and Their Climatic Controls Since 1980' led by researchers at IIT Indore.

With debates on water security and Himalayan disasters intensifying, the study provides fresh insights into how a warming climate is transforming the Ganga at its very source, authors say, urging for sustained field monitoring and the integration of high-resolution climate projections to refine future forecasts from glacierised basins

Using data from four decades (1980-2020) and advanced hydrological modelling, the study finds that snowmelt remains d...
