Recent study has reconstructed the long-term discharge flow of the Gangotri Glacier System (GGS), the source of the upper Ganga basin feeding the Bhagirathi River in the central Himalayas.With climate change driving faster glacier melt globally, glaciologists are closely examining how changes in Gangotri’s discharge patterns could affect water availability, river flow, and long-term sustainability of the region’s ecosystems and livelihoods.
