Climate crisis likely behind devastating Nepal-Tibet floods that killed more than 1,300, first study finds

Scientists say global heating was a destabilising factor in collapse of 200,000 sq metre glacier in August

Climate breakdown probably weakened the glacier that collapsed causing catastrophic floods and killing hundreds of people in Nepal and Tibet last month, the first scientific study of the disaster has found.

Researchers identified unusually warm conditions before the glacier's collapse, which sent an avalanche of 110m cubic metres (3,885 cu ft) of snow and ice into the valley below. This triggered flash floods on an almost unprecedented scale, hitting communities downstream without warning.
