Glacial Lake Outburst Floods: A New Climate-Related Threat from Above

As the climate changes and glaciers melt, a lesser-known threat lurks in alpine areas: glacial lake outburst floods. These events happen rapidly, releasing huge amounts of water with little or no warning. Unsuspecting communities lying in the flood path can suffer serious losses.
