Scientists Link Nepal's Deadly Flood to Climate-Driven Cascade of Failures
A team of over 20 international scientists concluded that the August 2026 flood in Nepal was not caused by a single event, but by a complex cascade of factors intensified by human-driven climate change. The disaster, which killed at least 1,300 people and left over 5,000 missing, began when a massive chunk of rock and ice from Langtang Lirung mountain collapsed. This avalanche released energy equivalent to a magnitude 5.2 earthquake, melting ice instantly and triggering a flood wave that traveled over 20 miles downstream. The analysis highlights how rising temperatures, thawing permafrost, and glacier thinning weakened the mountain's stability, making such an unprecedented event possible.
