There are also charts at this link:
Between 1992 and 2011, the Antarctic Ice Sheets overall lost 1350 giga-tonnes (Gt) or 1,350,000,000,000 tonnes into the oceans, at an average rate of 70 Gt per year (Gt/yr). Because a reduction in mass of 360 Gt/year represents an annual global-average sea level rise of 1 mm, these estimates equate to an increase in global-average sea levels by 0.19 mm/yr.

Skeptic arguments that Antarctica is gaining ice frequently hinge on an error of omission, namely ignoring the difference between land ice and sea ice.

... the ACE CRC report says that in one area of Antarctica – the Bellingshausen Sea – the rate of sea ice loss is actually greater than the fastest melting regions of the Arctic.
As counter-intuitive as it sounds, Dr Jan Lieser, lead author of the ACE CRC report, told me the increase in sea ice is consistent with the changes in a warming world.
The sea ice is sitting at the interface of the ocean and the atmosphere, and so it gets a double-whammy effect. We actually understand the physics of this quite well. It is because of the warming that we can see the sea ice increasing at the moment.
Speaking from Hobart and an international gathering of scientists to discuss polar sea ice, Dr Lieser said the picture of change in the Antarctic was complex.
But he said increased wind, wave and storm activity in the Antarctic helped to stir up the waters, creating ridges and rifts that helps sea ice to thicken.
Professor Ian Simmonds, of the University of Melbourne's School of Earth sciences, also told journalists that while it might seem paradoxical to have sea ice growing in a warming world, scientists understood the mechanisms behind it.
He said an increase in westerly winds across the continent which were linked to increasing greenhouse gas emissions were helping to create ideal conditions for ice to form, particularly in those areas where there have been marked rises in ocean ice.
... But the ACE CRC report notes that the current modest trend in rising Antarctic sea ice will likely be short lived.
CryoSat, a European Space Agency Earth-observing satellite, has found a sharp increase in the rate at which Antarctic land ice is melting—it’s losing a staggering 159 billion (yes, billion, with a b) tons of ice every year. Previous measurements (made from 2005 to 2010) were lower, closer to 100 billion tons per year.
Greenland is more vulnerable to melting that previously thought, and it turns out the culprit is the same as for Antarctica: warming ocean water.
Arctic sea ice loss continues apace. It reached a record low extent in 2012, and this year the amount of ice has been consistently below the amount of ice in 2012 for the same day and month. I’ll note that in 2012 there was an unusual event; an ice dam collapsed, allowing the melting of a large amount of ice. That’s why the year broke the record. But, despite the unending deceptions from the deniers saying arctic ice “recovered” in 2013, it is in fact still far, far below average, and the overall trend over time is for more loss.
Please correct me if I'm wrong, but I've always believed that more ice melts as temperatures increase. Just a hunch I spose, but anyway...
