Summary: A World Weather Attribution report says human-caused global warming thinned glaciers and thawed mountain permafrost, likely contributing to destabilization of a Himalayan slope. The analysis links the Aug. 26 collapse and subsequent catastrophic flooding in Nepal to long-term climate fingerprints, while noting it was not the sole cause and that a 2015 earthquake may have weakened the rock years earlier.
WHO: World Weather Attribution; Ben Clarke (Imperial College London)

WHEN: Sep 16, 2026 at 8:00 PM ET
