20 Years After the North Pole Melting
22 Oct 2009

British polar expert, Peter Wadhams, reveal unpleasant facts about the Arctic Ocean some time ago. About 20 years later, exactly the summer, frozen in the Arctic ocean will become ice-free waters. Sea levels will rise and the habitats of animals such as seals and polar bears are threatened vanished. ''The majority of withdrawals occurred in the first decade, although winter ice (Arctic Sea) are still going to last for several hundred years, "said professor of marine physics at the University of Cambridge was, as reported by Reuters yesterday (15/10) .

The impact, he added, at the northern end of the earth's surface will look blue when photographed from outer space. Not white as it looks today. In addition, the thawing of permafrost is going to open new shipping routes in the sea north of Russia. Wadhams and some other experts claim that the melting of Arctic Sea ice is the most tangible evidence of global warming. Therefore, they asked the UN and world leaders who will discuss new climate treaty in Copenhagen, Denmark, in December focused on that fact.

In his research, one of the famous sea-ice experts at the world that compares the data from the British Navy (Royal Navy) and a British polar adventurer, Pen Hadow. Royal Navy to do the calculation of ice thickness through their submarines in 2007. Meanwhile, Hadow and his team had done the calculation of ice thickness with 1500 holes drilled in the Arctic at the beginning of this year.

At that time, Hadow and his team, Catlin Arctic Survey, found the average thickness of ice floating in the Arctic about 1.8 meters. "These data support a new consensus - based on seasonal variations according to the vast ice sheet and its thickness, changes in temperature, wind speed and composition of ice-that would be ice-free Arctic Ocean in summer next 20 years," said Wadhams told the BBC.

Dr Martin Sommerkorn of WWF's Arctic program responded to these reports seriously. Because, according to him, greatly affect the Arctic climate. "The layer of ice in the Arctic Sea is at least a neutral position on the earth's climate system. Therefore, if the ice is disappearing, the world's climate would be a mess, "he explained. To be sure, he added, a quarter of the earth will be flooded. Often called Air Conditioning (AC) was the earth, the Arctic plays a vital enough to stabilize the world climate. If the ice in the waters covering an area of 14 million square kilometers of it melts during the summer, ocean color around the world will be darker.
