JW: It seems Antarctica is just being stubborn for now. Since cold is defined as the absence of heat, and globally temperatures are on the rise,  Antarctica is becoming less cold. It may be that Antarctica's unique geographic position with regard to ocean currents and continental land masses, coupled with it's massive ice volume has been preventing runaway warming. Like an ice cube in a glass of water in a warm room. It lasts for awhile and keeps the water cooler then it could be. But eventually, the water becomes the same temperature as the room. Antarctica is the ice cube in the glass. The quest is no longer if it will succumb, but when.
Anyway, here's a site with some more data to confound the obvious. http://www.climatecentral.org/news/antarctica-at-risk-of-runaway-melting-20189
