Fuzzy math: Arctic sea ice volume is allegedly decreasing both faster and slower than Arctic sea ice extent

Axel Schweiger, principal oceanographer at the Polar Science Center told us:
"With respect to ice volume from PIOMAS for this summer (and we are not finished), the change from 2011 to 2012 looks actually much less dramatic than the ice extent change and rather in line with previous year to year losses."

"There is much more open ocean than there used to be," says NSIDC research scientist Walt Meier. "The volume is decreasing even faster than the extent [of surface area] as best as we can tell," based on new satellite measurements and thickness estimates provided by submarines.
