Also warmer temperatures mean more moisture in the atmosphere, so more snow and rain, which makes the cooler surface water less dense so it mixes less with the lower warmer water, resulting in less ice melting. This may also be contributed to by the accelerating melting of antarctic land ice.
From what I remember they aren't that concerned about antarctic sea ice going up or down.

And I believe that most of the Antarctic ice cap is on land which doesn't heat up as much, while the ocean warming in the arctic is likely to have a bigger impact. Just a guess.
