A study on Rulung Glacier in Ladakh reveals that rising temperatures are intensifying interactions between meltwater and rocks, altering the chemical composition of water flowing into the Indus river basin.Researchers warn that these changes could impact ecosystems, agriculture, and drinking water supplies downstream.The Himalayas, known as Asia's 'Water Tower,' store vast freshwater reserves in glaciers that sustain over a billion people.

Glacial meltwater carries dissolved minerals and nutrients from rock interactions, but accelerated melting due to climate change may release trace metals like aluminium and manganese.While moderate mineral increases can benefit ecosystems by buffering acidity, excessive sediments and ions could harm cold-adapted species.For agriculture, glacier-fed rivers provide essential irrigation, but long-term salt buildup risks soil quality.

The article emphasizes the need for continuous monitoring of water quality alongside glacier retreat studies to build climate resilience in regions like Ladakh.
