At least the Navy thinks so. Nothing else supports that contention as yetunless you want to count on visual areal extent to determine average thickness.
I do have questions. How is thickness determined? Thatis not obvious at all. Can the data beskewed by non compact ice flows?
Arcticcontinues to have above average winter conditions conforming to a warmer upperlayer of ocean. This may well be gettingwhittled down and 2007 in fact could have made its contribution by shifting alot of ice into a small area.
Yet forty years of past warming was certainly theresult of a new imbalance of warm water entering the
Arctic. No evidence has surfaced to suggest that thishas ended at all.
Welcome to the confusion that is the science ofpredicting sea ice outcomes.
Area OfThick Arctic Ice Has Doubled In The Last Two Years
US NavyPIPS data shows that the area of ice greater than 2.5 metres thick – hasdoubled since the same date in 2008.
