Not exact matches
I've had trouble finding estimates of loss of
ice thickness, but it is clear that
arctic sea ice has thinned considerably.
We see that the
arctic sea ice extent has increased since then, currently up around the 2004 levels, so we're told that it's not actually the area, it's the
thickness and what birthday it's celebrated.

Ice Service, 4.7, Multiple Methods As with CIS contributions in June 2009, 2010, and 2011, the 2012 forecast was derived using a combination of three methods: 1) a qualitative heuristic method based on observed end - of - winter arctic ice thicknesses and extents, as well as an examination of Surface Air Temperature (SAT), Sea Level Pressure (SLP) and vector wind anomaly patterns and trends; 2) an experimental Optimal Filtering Based (OFB) Model, which uses an optimal linear data filter to extrapolate NSIDC's September Arctic Ice Extent time series into the future; and 3) an experimental Multiple Linear Regression (MLR) prediction system that tests ocean, atmosphere and sea ice predicto

We interpret the split of 2013 Outlooks above and below the 4.1 level to different interpretations of the guiding physics: those who considered that observed
sea ice extent in 2012 being well below the 4.1 level indicates a shift in
arctic conditions, especially with regard to reduced
sea ice thickness and increased
sea ice mobility; and those who have estimates above 4.1 who support a return to the longer - term downward trend line (1979 - 2007).

THERE HAS BEEN A WARMING TREND FROM THE 70s THRU THE LATE 90s,... accompanied by other changes tied to a warming trend (record low
arctic sea ice extent &
thickness, retreating glaciers, retreating snow lines, warming ocean surface temps, increases in
sea height, de-alkalinizing oceans).
As surface temperture is altitude dependent one might have thought the first thing to check would be a map, as the
arctic ice lies at
sea level + 9 % of its
thickness, while the antarctic
ice sits several kilometers high in the sky, and the surrounding apron of the stuff is immune to windage because of the circumpolar continent in its midst.
