Scientists investigating the cause of a deadly flash flood in Nepal on Wednesday believe it was most likely triggered by a massive chunk of glacier ice breaking off and temporarily blocking a river. According to preliminary findings, the event may have caused water to back up behind the ice, forming a natural reservoir, before it breached and surged downstream with tremendous force just hours later.
The phenomenon raises growing concerns about the risks posed by glaciers in the Himalayan region as global temperatures rise. Warmer temperatures are accelerating glacier melt, creating more glacial lakes and increasing the likelihood of ice collapses, which can trigger severe flash floods and landslides.
Experts warn that similar events could become more frequent in mountainous areas, where communities face escalating threats from disasters linked to melting ice.
