Nepal village living on edge

Local climate changes are affecting the lives of thousands of people who inhabit the foothills of the Himalayas.
 
Rising temperatures are causing glaciers in the mountains to melt, and the water threatens to sweep away whole villages.

In Nepal, the government is taking action to prevent glacial lakes in Rolwaling valley, east of Everest, from bursting, Subina Shrestha reports.

Experts are looking into an early-warning system that could protect remote communities from environmental disaster.
