Surprisingly, the ice sheet covering the Arctic and that since 2007 had fallen to worrisome levels, returns to normal levels s . The scientific community blamed global warming as the cause of the reduction of the ice but this new information has perplexed scientists do not stop to explain how it happened. The large white heart beats again.
Experts predicted that the Arctic ice completely disappear by 2015, given the speed with which the ice sheet was lost in 2007 and generated some alarming data and rather pessimistic. According to the scientist Carlos Duarte of Mediterranean Institute for Advanced Studies (CSIC and University of Balearic Islands as) the current rate of warming of the North Pole (0.4 degrees Celsius per decade) will dilute the vast Arctic ice cap to let the size of an ice cube in about 5 years. However, nature just shake up the expectations and left with their mouths open to scientists who had clear this event.
Mark Serreze, director of National Information Center Ice Snow and (NSIDC) in Colorado, United States, did not hide his amazement at the recovery of the Arctic ice after the great thaw of 2007, when the layers are reduced to the lowest extent on record for centuries. According to experts, this has led to the phenomenon they call " Arctic Oscillation " a change of polar winds from the Bering Sea, whose presence had the effect of large refrozen North Pole area, leaving it to levels similar to those recorded in 2001. Also because of this event so unusual winter they have had in some parts of the world (Northern Europe and Eastern North America), which have been extremely low temperatures.
do not understand why this sudden change of wind or the scale of the freezing North Pole has returned to its ancient ice, leaving scientific estimates for soils and producing a sensation in the scientific community does not have all the facts checked. However, the experts agreed that, despite the spectacular nature of the phenomenon, this has little relevance to long-term climate change.
