Another denier cult lie.
There is a net ice mass loss at both poles, as a number of studies have confirmed. The yearly growth and shrinkage of the relatively tiny fringe of sea ice around Antarctica has no bearing on the measured yearly increasing loss of ice mass from the ice sheets and shelves resting on the continent of Antarctica.
Ice Sheet Loss at Both Poles Increasing, Major Study Finds

WASHINGTON -- An international team of experts supported by NASA and the European Space Agency (ESA) has combined data from multiple satellites and aircraft to produce the most comprehensive and accurate assessment to date of ice sheet losses in Greenland and Antarctica and their contributions to sea level rise.
I make a comment about the Antartic and you reply with a combination of information about many sites. Slippery.
Anyway, review this for a better understanding:

Mass Gains of the Antarctic Ice Sheet Exceed Losses
Zwally, H. Jay; Li, Jun; Robbins, John; Saba, Jack L.; Yi, Donghui; Brenner, Anita; Bromwich, David
Abstract:
During 2003 to 2008, the mass gain of the Antarctic ice sheet from snow accumulation exceeded the mass loss from ice discharge by 49 Gt/yr (2.5% of input), as derived from ICESat laser measurements of elevation change. The net gain (86 Gt/yr) over the West Antarctic (WA) and East Antarctic ice sheets (WA and EA) is essentially unchanged from revised results for 1992 to 2001 from ERS radar altimetry.
Imbalances in individual drainage systems (DS) are large (-68% to +103% of input), as are temporal changes (-39% to +44%). The recent 90 Gt/yr loss from three DS (Pine Island, Thwaites-Smith, and Marie-Bryd Coast) of WA exceeds the earlier 61 Gt/yr loss, consistent with reports of accelerating ice flow and dynamic thinning. Similarly, the recent 24 Gt/yr loss from three DS in the Antarctic Peninsula (AP) is consistent with glacier accelerations following breakup of the Larsen B and other ice shelves. In contrast, net increases in the five other DS of WA and AP and three of the 16 DS in East Antarctica (EA) exceed the increased losses.

And this:
The results of ICEsat measurements are in for Antarctica, and it seems those claims of ice mass loss in Antarctica have melted now that a continent wide tally has been made. This was presented in the SCAR ISMASS Workshop in Portland, OR, July 14, 2012 and was added to NASA’s Technical Reports server on September 7th, 2012. H/T to WUWT reader “Brad”. What’s interesting (besides the result) is that the report was prepared by Jay Zwally, whose “ice free Arctic by the end of summer 2012″ prediction is about to be tested in 12 days. It also puts the kibosh on GRACE studies that suggested a net loss in Antarctica. Note there’s the mention of the “climate warming, consistent with model predictions” at the end of the report. They’d say the same thing if ICEsat had measured loss instead of gain, because as we’ve seen before, almost everything is consistent with warming and models no matter which direction it goes.
Here’s the video presentation. The report abstract follows.
