Earl, this is not quite correct. Antarctica has had ice growth the last three years, but the Arctic has lost more. Right now, according to NASA, the Earth is losing about 13,500 square miles of sea ice per year.
The theory behind Antartica's ice expansion states the ozone depletion above Antarctica has caused more violent storms over the continent forcing a vortex of wind to flow over the Ross Sea where 85% of the continents ice expansion has happened.
