This diagram from NASA shows the warming trend in Antarctica. Of course the denialists have seized upon those pale blue cooling areas in the middle of the continent, to the exclusion of everything else: ...This image shows trends in skin temperatures—roughly the top millimeter of the land, sea ice, or sea surface, rather than air temperatures—and it shows the long-term change in yearly surface temperature between 1981 and 2007. Warming areas appear in shades of red, and cooling areas appear in shades of blue. One of the most dramatically warmed areas appears at the former location of the Larsen B Ice Shelf, which shattered in 2002. Although some 300 kilometers (185 miles) farther south than the Larsen, the Wilkins Ice Shelf seems to have succumbed in the same fashion in early 2008.
