Glacier-dominated mountains play a major role in providing water to large numbers of people. These glacier-dominated areas also pose unique challenges to downstream communities as they adapt to recent and continuing global climate change. Two of the more serious problems in high mountain regions include decreased water supply reliability and increased threats from glacial lake outburst floods (GLOFs), or moraine-dammed lakes left behind receding glaciers that can cause enormous downstream devastation if suddenly released by triggers such as an earthquake or overhanging ice.
