Global warming hoax researchers: Our guess at Arctic sea ice volume in 2010 was less than our guess at Arctic sea ice volume for other years

Arctic sea ice falls to record low [volume] - Telegraph

The minimum summertime volume of Arctic sea ice fell to a record low last year, researchers said in a study to be published shortly, suggesting that thinning of the ice had outweighed a recovery in area.

The authors developed a model predicting thickness across the Arctic Ocean based on actual observations of winds, air and ocean temperatures.

The approach has some detractors because it is focused is on modelling rather than direct observations of thickness, and therefore contains some uncertainty.
