Why Nepal faces another flood threat from a new lake on China border?

A new flood threat is emerging along the Nepal-China border after a glacier collapse triggered massive flash floods and mudslides. The collapse created a natural barrier lake as rocks, ice, and debris blocked a river channel. Authorities fear the rising lake could overflow or suddenly burst, sending dangerous floods downstream. Nepal and China are monitoring the situation as rescue operations continue in affected areas. Experts say warmer temperatures and unstable glaciers are increasing the risk of such disasters in the Himalayas.
