The Arctic ice cap has reached its minimum Facts
As the satellite images, the size of the Arctic ice cap reached its year low and thus broke the record. As of September 16, 2012 glacier area was 3.41 km2. It is 776,000 km2 smaller than in 2007, when the sea ice also was at critically low levels. For comparison, the area of Texas in the United States is about 695 km2.
Despite the fact that the September record may well hold the status of not only summer but year low, scientists fear that the change in wind direction can send floating ice in the warmer water, which will accelerate the melting Arctic. For it is only in the last two weeks of ice was on 518 km2 less.
In 2012, the minimum ice area increased by almost half compared with the average over the period from 1979 to 2000. In addition, the history of Arctic exploration decline for the first time ice cap has topped 4 million km2. Even on computer models failed to predict such a strong pace of melting.
Except for the area of the ice and its thickness decreases. Even perennial sheets of ice that never melted, now susceptible to fracture. Over time, they are replaced by thin ice that melts easily in the summer again. The Arctic is warming because of frequent visitors are uncharacteristic of precipitation, which further break the ice rains and rains, melting it from above. Perhaps for 2012 the emergence of such precipitation has played a fundamental role in the process of melting.
