Thickening Arctic Ice?
At least the Navy thinks so. Nothing else supports that contention as yet unless you want to count on visual areal extent to determine average thickness.
I do have questions. How is thickness determined? That is not obvious at all. Can the data be skewed by non compact ice flows?
continues to have above average winter conditions conforming to a warmer upper
layer of ocean. This may well be getting
whittled down and 2007 in fact could have made its contribution by shifting a
lot of ice into a small area.
Yet forty years of past warming was certainly the result of a new imbalance of warm water entering the
Arctic. No evidence has surfaced to suggest that this
has ended at all.
Welcome to the confusion that is the science of predicting sea ice outcomes.
Area Of Thick Arctic Ice Has Doubled In The Last Two Years
US Navy PIPS data shows that the area of ice greater than 2.5 metres thick – has doubled since the same date in 2008.
