Are the Himalayan glaciers at a tipping point?

The Himalayan glaciers are melting more rapidly as global temperatures rise, raising concerns about the future of ecosystems and communities across the Himalayan mountain range. Glaciers store more than two thirds of the world’s freshwater and help regulate global temperatures by reflecting the sun’s rays.

Across South Asia, melting ice is contributing to the formation of unstable glacial lakes and increasing the risks of floods, droughts and avalanches. The Himalayas are a vital source of water for millions of people, supporting agriculture, energy production and livelihoods from tourism.

Experts warn that continued glacier loss could have significant consequences for people living in the region and the mountainous ecosystem, but what can be done to respond to these changes?
