Study: Climate change key driver of deadly Nepal-China flood

Scientists attribute the deadly flood to a compound crisis of long-term warming, glacier retreat, permafrost thaw, and geological instability, with a 2015 earthquake as a contributing factor. The attribution is based on research findings, not direct observation, and the exact mechanism remains partially uncertain. This underscores the growing risk of glacial lake outburst floods in the Himalayas as climate change accelerates.
