The Arctic ice thickness has decreased considerably during the summer season of 2007 reaching a record low in late September.

The thaw has affected areas unthinkable for scientists. Places where previously only produced small reductions in the thickness of sea ice.

The main reason for this is the icing warming of the earth's surface and the resulting rise in temperatures, which have reached 22 ° in areas where previously there were over 5th.

The surface ice of the North Pole now has a length of 4.13 million kilometers. According to experts in this area could disappear by 2020.
