The report added that the ice is presently leveled at 7.6mn sq miles but it is rising continuously. The Arctic also continues to melt ice and the minimum level might is somewhat lesser than the former year. According to NSIDC, this level of the ice is the 6th lowest level in the entire satellite history.
The NSIDC's statistics recorded, Arctic sea ice level till Sept. 15th was 1.96mn sq miles which was 11,600 sq miles under the same date in previous year. Though, it has been observed that the Arctic sea level remains low as studying in comparison with the 1981-2010 average ratios.
Axel Schweiger, chairman of the University of Washington's Polar Science Center in Seattle said: "When you see the short-term statistics, it seems like there is no ice loss within previous years, however I feel it's something you need to observe from a larger perspective (long-term data) that the sea ice is actually decreasing. But, in contrast, you can't expect necessarily that it would be a record low every year."
The NSIDC researchers stated that the Arctic sea level declined at the rate of 11,100 sq miles/day in the first 15 days of the month that is equals to double as the 1981-2010 average ratios of sea ice declining for this period.
The NSIDC scientists added that the major cause of Antarctic's sea ice increase is global warming and it has also led to the decline of the Arctic's sea ice. They added that Antarctic's sea might increase due to the powerful winds. These winds are highly effective because the southern polar vortex is agitating the air closer to Antarctica as a result of the ozone hole and greenhouse gases.
