Record-breaking: The Jakobshavn Glacier in Greenland flows 17 kilometers per year towards the sea - and could be even faster. His ice sheets contribute to sea level rise.

The Jakobshavn Glacier in Greenland is flowing at a record pace from the sea: The ice is moving annual average almost three times faster than it was in the 90s, researchers from the University of Washington in Seattle and the German Aerospace Center (DLR).
Thus, the ice flowed in the summer of 2012 per day more than 46 meters seaward. That was probably the largest ever recorded speed of a glacier in Greenland or Antarctica, the researchers write to Ian Joughin in the journal "The Cryosphere". The pace could therefore increase significantly - and the sea levels faster than expected.
The Jakobshavn glacier flows into a fjord on the west coast of Greenland into the sea and was considered earlier as one of the fastest flowing glacier world. From it probably also dates that iceberg, the "Titanic" collided with the on her maiden voyage in 1912.
