Ice loss in the Arctic increases

Ice loss in the Arctic increased Weather and Climate

According to a new study by NASA and the old thicker layer of ice covering the waters of the Arctic is melting much faster than the recently formed ice. This trend threatens the entire ice cap in the Northern Hemisphere and the promise it accelerated extinction.

How to assure researchers over the past decade, the level of centuries of ice cover has decreased by 17.2%. The photo presented below shows the part of the ocean in the November-January 1980 and the present time. Reduction of land with more durable ice cap in 2012 is evident (Figure marked bright white).

In colder regions of the Earth, there are three types of ice. The first type — a multi-year ice, which can remain intact for up to two years, including during the warm summer months. Second, the young type of ice formed only during the winter and melts just after zero temperature. There is another type of multi-year ice, which can last about a year, but no more. According to NASA, such as the ice began to melt faster, its mass decreased by 12.2%, and the occupied area by 13.5%.

Thus, we have been steadily losing important for the planet fresh water due to the constant increase in air temperature in the Arctic region. In addition, the warmest year in the Arctic mean reduction in the formation of new ice, which means that the probability that the new ice will turn into a long-term, is steadily decreasing.
