European Satellites Record Abrupt Change In Greenland’s Crucial Glaciers

Jakobshavn Isbrae has been the swiftest glacier for quite some time now, moving at a speed of 17 km per year. Whenever it picked up speed to meet the ocean, the part at front retreated and fell by almost 20 meters every year. However, a change has been recently noticed by European Satellites in one of the most important glaciers in Greenland.

There has been a reversal in the characteristics of the glacier now with the speed reducing significantly and instead of the thinning of the front end, it became all the thicker. Clearly, it is completely opposite of what it was doing all these years and it has got many experts thinking about the implications of it and if it going to be a permanent trend now or just a temporary breakout from normal.

Southwest Greenland houses this glacier and it is particularly famous for a large number of icebergs that it produces every time and how huge they turn out to be. From one end, a colloidal block falls out and moves towards the fjord and finally into Disko Bay. Speculations are that it was one of the icebergs spawned from this glacier that sealed the fate of titanic and sunk it. The reason why scientists keep a close watch on this glacier is because of the fact that it serves a major export of ice sheets from Greenland which is instrumental in the regulation of the sea level as well. However, a similar situation has happened before in the 2000s when the warm water from the ocean flowed backward and slightly heated up the forward end of it. Since there was very cold weather in 2013, its effect must have carried to ocean water which has gotten choked of its ability to pull it in through the Disko bay itself.
