Nepal Flash Floods

Scientists say a deadly flash flood in Nepal on Wednesday was likely caused by a glacier chunk breaking off and temporarily damming a river. This may have led to a surge of water downstream, killing at least 353 people and leaving over 1,300 missing. The U.S. Geological Survey reported a magnitude 5.2 glacier collapse, causing catastrophic debris flow. Researchers are still analyzing satellite and ground-level data to understand the event. Experts say it's too early to directly link the disaster to global warming, but note that rising temperatures increase such risks, especially in the rapidly warming Himalayan region.
