Watch: How a glacial collapse caused devastation downstream

The US Geological Survey said the floods in the Nepal‑Tibet border were triggered by a "glacial collapse" — meaning a glacier or a portion of a glacier had disintegrated. Initial reports led authorities to judge that an earthquake had been the cause. The origin of the glacial collapse has not been determined, but scientists warned that Himalayan glaciers are melting at an accelerating rate due to rising temperatures and climate change.
