A glacier and rock collapse in Nepal last month triggers catastrophic flooding, killing nearly 1,400 people and leaving thousands missing, according to reporting from multiple outlets.
Several sources say a report released this week links the disaster to human-caused warming that affects mountain stability. They describe how higher temperatures thin glaciers and thaw mountain permafrost in the Himalayas, which can reduce the stability of slopes and make collapse more likely.
The outlets generally agree on the core mechanism—warming contributing to glacier shrinkage and permafrost thaw—but they vary slightly in emphasis. Some focus more on the thawing of mountain permafrost and its role in destabilizing the slope, while others highlight the glacier and boulder collapse and the resulting floods. All attribute the assessment to scientific analysis presented in the newly released report, rather than to direct observation of a single cause.
