Greenland's largest glaciers to melt faster than thought says study

Timelapse images of a large calving event at the Helheim Glacier, as published research shows that the three largest glaciers in Greenland -- which hold enough frozen water to lift global sea levels some 1.3 metres -- could melt faster than even the worst-case warming predictions. A team of researchers based in Denmark and Britain used historical images and a host of other data to estimate how much ice had been lost from Greenland's Jakobshavn Isbrae, Kangerlussuaq Glacier and Helheim Glaciers in the 20th century.
