To AGW? It shows a long term warming trend over most of the Antarctic, specifically around the Ross Sea and the peninsula. You don't need a measurement of area, just a notion of circumference on a globe. Besides which, the piece you link to indicates that warmer ocean temps produce more precipitation on the pole, which results in cooling surface temps.

At best this speaks against your devout belief in the antithesis of AGW. But all things being equal, taken by itself, it says all of nothing either way.

What are you trying to demonstrate? That you can use HTML to embed essentially pointless data?
