A lake in a remote region in Patagonia in southern Chile faded away in less than two months time. Accelerated melting of glaciers caused the lake to first swell with additional fresh water; then, part of the adjacent glacier that once held the lake in place thinned and broke and the icy fresh water flowed into the sea.

While the advance and retreat of glaciers occurs on a cyclical basis,  the lake has never completely disappeared during such cycles in the past. Glaciologists blame rising global temperatures for the accelerated melting.
