BENGALURU, India — Human-caused global warming thinned glaciers and thawed mountain permafrost, likely helping to destabilize the Himalayan slope that collapsed last month and unleashed catastrophic flooding across Nepal, according to a report released Thursday.
More than a thousand people have died and thousands are missing in Nepal after the August avalanches. Experts say a warming climate is making Himalayan glaciers and slopes increasingly unstable. The disaster also showed that current warning systems cannot identify all new types of mountain floods.
