Not only does this low - pressure area, or cyclone, look bigger, more intense and longer - lasting than the one from last year, the ice also seems to be in a weaker state than ever, as evidenced by the fact that 2012 trend lines on both sea ice area and sea ice extent graphs track lower than previous record years, despite weather that until recently would completely stall the decline.

The area of Arctic sea ice was nearly 30 % greater in August than a year ago, according to recent satellite data, though projections based on longer - term trends suggest the sea ice will continue its decline over time.

If this is correct, then the fact that the sea ice extent has been «declining since records began» (in 1979) doesn't mean that recent trends are unusual.

As sea ice declines, it becomes thinner, with less ice build - up over multiple years, and therefore more vulnerable to further melting.15 Models that best match historical trends project northern waters that are virtually ice - free by late summer by the 2030s.25, 26,12 Within the general downward trend in sea ice, there will be time periods with both rapid ice loss and temporary recovery, 27 making it challenging to predict short - term changes in ice conditions.
