Ice Melting at the poles:Wilkins ice shelf disintegration

For quite some time now scientists have been predicting ice melting at the poles. In past few years we saw massive breaking of ice from the poles specifically the Larsen Ice Shelf. (The Larsen A ice shelf disintegrated in January of 1995. The Larsen B ice shelf disintegrated in February of 2002.). 

Now in the past week scientist were again shocked by massive breakage of ice from Wilkins Ice Shelf. On March 25, 2008 a 405-square-kilometer (156 sq mi) chunk of the Wilkins ice shelf disintegrated, putting an even larger portion of the glacial ice shelf at risk. Scientists were surprised when they discovered the rest of the 14,000-square-kilometer (5,400 sq mi)ice shelf is beginning to break away from the continent. What is left of the Wilkins ice shelf is now connected by only a narrow beam of ice.

In 1993 Professor David Vaughan of the British Antarctic Survey (BAS) predicted that the northern part of the Wilkins ice shelf was likely to be lost within 30 years if climate warming on the Peninsula were to continue at the same rate.

The breakage of ice would also have serious impacts on deep sea life and polar bears. Loss of ice shelves poses a grave danger to basic life like krill and crabs which are vital to regions ecology. There loss will eventually effect the larger creatures like penguins and disturb the eco balance.

If the current melting trend continues we will be facing grave consequences like rising sea levels, massive flooding and disturbance in Ecology of the region in not so distant future.
