Climate Change Shifts Gangotri Glacier Discharge Patterns
The Gangotri Glacier, a key source for the Ganga river, has shown significant shifts in its discharge patterns due to climate change. Researchers found changes in the timing and sources of meltwater discharge over four decades, highlighting the need for ongoing monitoring to manage water resources effectively.

Researchers have discovered significant changes in the discharge patterns of the Gangotri Glacier, crucial for feeding the Ganga river. About 64% of the discharge is derived from snowmelt, though its contribution has seen fluctuations due to climate change, while glacial melt accounts for 21% and rainfall runoff 11%.
The study, conducted by IIT Indore scientists with international partners, analyzed data from 1980-2020. They observed that the peak discharge month shifted from August to July after 1990, correlating with increased early summer temperatures and reduced winter precipitation.
These findings emphasize the impact of climate change on hydrological patterns and underscore the need for continuous monitoring and improved water resource management in glacier-fed river systems.
