India, Sept. 21 -- World Weather Attribution scientists say fossil fuel-driven warming played a role in the occurrence and intensity of Nepal's August 26 cascading flood disaster.

The disaster began when rock and ice collapsed from a glacier on Langtang Lirung, triggering a fast-moving flood of water, ice and debris in the Lhende river.

Researchers said climate change acted as a destabilising factor on a slope already weakened by geology, the 2015 Nepal earthquake, glacier retreat and thawing permafrost.

The study said the event was beyond the design and predictive limits of existing risk-reduction measures, highlighting the limits of adaptation in rapidly warming mountain regions.
