Nice Article! There are even a lot of sources (such as NASA, your average pseudo scientist ;) ) claiming that Antarctica sea ice is expanding:

"Since the late 1970s, the Arctic has lost an average of 20,800 square miles (53,900 square kilometers) of ice a year; the Antarctic has gained an average of 7,300 square miles (18,900 sq km)"

Furthermore, speaking about the ice sheets, the major part of the Antarctica one is growing because climate change is enhancing Antarctic Precipitation. (there is very nice scientific article by Zwally et al. (2005) discussing this trend based on data from 1992 - 2002. Also the IPCC report from 2007 is supporting this claim. Nevertheless, there is a lot of uncertainty about the fate of the Western Antarctic Ice Sheet so in the end, no knows for sure!
