One aspect of the recently published study on Chukchi Sea polar bears (Rode et al. 2014 [now in print] 2013; see here and here) has not been stressed enough: their finding that the differences in overall condition between bears in the Chukchi and Southern Beaufort Seas came down to disparities in spring feeding opportunities and therefore, the condition of spring sea iSea polar bears (Rode et al. 2014 [now in print] 2013; see here and here) has not been stressed enough: their finding that the differences in overall condition between bears in the Chukchi and Southern Beaufort Seas came down to disparities in spring feeding opportunities and therefore, the condition of spring sea isea ice.

The strength of these currents is influenced by the location of the polar fronts as determined by sea level pressures in the Southern and Northern Annular Modes.
And it is known that the southern polar regions «see - saws» with the northern — so when the north polar is on the up cycle — the south polar in on a downer (Bob Tisdale's graph of the southern ocean SSTs shows this clearly for the «global warming» period of 1980 - 2005 — and the Peninsula Region just catches a flow - in from warmer seas to the north).

It is true that this is consistent with the idea that there has been continuous global warming, although it is complicated by the fact that the Antarctic sea ice extent still seems to be about the same, i.e., the «global» warming only seems to have affected the northern polar region, not the southern polar region.

Hi iceman, Sorry for the tardy reply, that pesky real life thing again...:) The reason there is so little excitement about the record high sea ice extent in the antarctic (aside from it having no appealing potential victims, like polar bears) versus the record low arctic sea ice is probably because the southern record is only a matter of 2 % anamoly, whereas in the north we are now looking at levels over 40 % below average.
