Currently 30.2 km long and between 0.5 and 2.5 km wide, Gangotri glacier is one of the largest in the Himalaya. Gangotri has been receding since 1780, although studies show its retreat quickened after 1971.
This pair of images shows the retreat of the Sermersuaq (Humboldt) Glacier in northwestern Greenland between 2000 and 2008. Sermersuaq Glacier is the widest tidewater glacier in the Northern Hemisphere.
NIWA scientists stated that this glacier had retreated by 5 kilometers (about 3 miles) over the previous three decades. They also stated that New Zealand glaciers on the whole had lost 5.8 cubic kilometers (roughly 1.4 cubic miles) over the same time period.
Researchers from NASA and the University of California, Irvine (UCI) have gained an unprecedented view of ice melting on the floating undersides of glaciers. In the process, they detected the fastest ongoing rates of glacier retreat ever observed in West Antarctica.
