The minimum ice cover of the Arctic region after 2012

The ice cover of Arctic region in 2016 reached to its second minimum like 2007. The expansion of sea ice in 10th September was 140 million and 140 thousand square kilometer that is a little more than 3 million and 390 thousand square kilometer in 2012. The ice cover of Arctic increases each year in winter and autumn seasons and decrease in spring and summer. This phenomenon is one of weathering changes important sign. The center of ice and snow data of USA records the dimension of ice cover in Boulder, Colorado by satellite measurements.  However, this center said declared data are primary and changes of wind can push back the ice cover.  Ted Scambos the center's chief scientist, said: These figures really show that by being warmer the weather in the next few years, we will have seen a dramatic decline in Arctic ice cover. The sharp drop of this year was unexpected because scientists expected less melting the ice due to atmospheric pressure and cloudy weather in June and July. Land and sea temperature record in 2015 that still was continued by breaking records in 2016 makes this assumption that perhaps the melting of Arctic sea ice reached a new level this year. But some scientists, including experts from the Reading University in Great Britain argued that 2016 will not be as bad as 2012. The ice cover level in 2012 was reached to 50 percent in 1979 to its average in 2000.
