The Kangerlussuaq Glacier ( Greenlandic for Big Fjord , the outdated spelling Kangerdlugssuaq is often used) is a glacier in East Greenland that flows into the fjord of the same name . He gained notoriety through his role in the discussion about glacier retreat in Greenland and its dangers for the global climate.
The Kangerlussuaq Glacier transports ice from the Greenland ice sheet to the Atlantic. About four percent of the ice production of the entire ice sheet reaches the sea via this glacier, so it produces most of the ice of all glaciers in East Greenland. With a flow speed of up to 14 km per year or 1.6 meters per hour, it is one of the fastest flowing glaciers on earth. This speed was reached in 2005 as a result of climate change . Since then, the glacier has receded a lot (up to four kilometers a year) and has lost a lot of volume and thickness, and the flow rate has also decreased again. Nevertheless, it was particularly portrayed by the Danish author Bjørn Lomborg as an example of a growing glacier. Critics accuse Lomborg of having faster flow rates with growth and confusing the glacier with the town of Kangerlussuaq in western Greenland, where there is no glacier of that name.
The Kangerlussuaq Glacier is one of several sea glaciers in Greenland where glacial quakes have been recorded.
