This one is meaningless because it spans only two years. We aren't talking about weather.

This one cherry picks. Never the less, it shows exactly what was predicted, an increase in the antarctic.

I think the problem here is the oversimplification you seem to have applied to the ice processes taking place on the Antarctic continent.
Precipitation, in the form of snow and frost due to temperatures that do not rise above freezing, accumulates on the continent and it's ice shelves. The rate of that precipitation, historically, classed Antarctica as a desert. The same is true at the North Pole. However, over millions of years, that ice has built up to an enormous thickness. Since models first examined what would be the results of global warming, increased precipitation in Antarctica has been forecast. It was never unexpected. It was never a surprise.
That ice slowly slides downhill which takes it, eventually, to the ocean. There, it slides off the coast and becomes a floating ice shelf that often extends miles out over the ocean's surface. Finally, at the outer edge of that shelf, the ice fractures off in large chunks which, at varying rates, disperse northward.
There are numerous mechanisms within that flow that affect the rates at which the ice moves:
o Warmer ocean waters surrounding the continent increase precipitation on the continent. Since it is still well below freezing on average, that precipitation comes down as snow and accumulates on the ice sheet. This tends to thicken the ice sheet, but, since it adds unassimilated mass, also tends to make the glacial flow rate increase, at least at the ice sheet's surface.
o As has been seen in Greenland to a larger extent, surface melting during the warmer Winter months generates melt water which works its way down to the bottom of the ice sheet and lubricates its glacial movement towards the sea.
o Given the lack of slope, the ocean-borne ice shelf is not driven by gravity to continue flowing and thus acts as a barrier, slowing the glacial flow. It is the plug in a tipped bottle that prevents it's emptying.
o The same warmer ocean water that has increased inland precipitation has increased melting and breakup of the floating ice shelf. As you know, several large shelves have catastrophically failed and unbound the ice sheets they had formerly restrained.
o The seaward flow rate in glaciers released by failed ice shelves has accelerated up to five fold.
The end result of those processes is that the rate at which ice formerly on land is moving into the sea, has increased dramatically over the last five decades. This is driving sea level rise. Sea level rise is not a good thing.
You and yours, concentrating on nothing but the precipitation-driven ice buildup on the continent, are blinding yourselves to an ongoing process which presents human society with a serious and imminent threat.

The only problem with your new excuse is that the Antarctic ice sheet is growing in size, not shrinking.
Ian, you know better. Yes, the predictions for the Arctic and Anarctic were wrong. For the Arctic, no one predicted the extent of the loss of ice we have seen in the last decade. For the Antarctic, both sea ice and continental ice was predicted to increase. However, do to the wasting of ice shelves and glacial outflow and erosion, the continental ice is decreasing, and the sea ice increase is very small compared to the loss of the ice in the Arctic.

Do you realize that simply means that ice is flowing from the land to the sea at an increased rate? All that extra ice shelf came from the ice sheet ashore.
The ice sheet is not growing in extent - it can not - it already occupies the entire continent. If it expands - as it is - it pushes itself off land and on to the surrounding oceans and raises the world's sea level.
And, by the way, I am not making excuses for anything. I have nothing for which to make an excuse. You, on the other hand...
Yeah, right. So if the ice sheet shrinks in size, it's proof of global warming. If it expands in size, it's proof of global warming.
When warmist cult members spout obvious idiocies like that, they demonstrate what total nutburgers they are.

Suuuuure it was... And you claim I lie...what a joke you are...
In a report on Monday's NBC Today about declining penguin populations in Antarctica, correspondent Kerry Sanders didn't take long to lay the blame on man-made climate change: "Penguins are most certainly the ambassadors to the bottom of the world....But the ambassadors are also sounding an alarm....ten of the world's 18 penguin species are in trouble....The ice that dominates this landscape is melting faster than ever before."

One of the warning signs that a dangerous warming trend is underway in Antarctica will be the breakup of ice shelves on both coasts of the Antarctic Peninsula, starting with the northernmost and extending gradually southward. Concluding statement in Mercer (1978)

Krill reproduction is wholly dependent on Antarctic sea ice conditions. Seasonal studies have shown that winters with reduced size and duration of winter sea ice coincide with poor krill reproduction. This is because the underside of sea ice is coated with ice-algae which serves as the main food for krill during the winter when phytoplankton is unavailable.

For the last two years, one of the largest international research programmes for 50 years has been focusing on the world's most remote regions - the Antarctic and Arctic.
IPY was officially launched in Paris on 1 March 2007, and will run until March 2009.
The International Polar Year (IPY) brings together thousands of scientists, from more than 60 nations, to participate in more than 200 projects.
And the issue at the top of the agenda is climate change.
"This is going to raise the profile of the issue of global warming among the international community," said Sir David King, the UK government's chief scientist at the opening.
"We know that what is happening to ice on the planet is a very clear indication of what is going to happen to the rest of us.
The first IPY, held in 1882-83, saw the world's first co-ordinated international expeditions to the polar regions.
And I can go on and on and on you lying sack of poo. You asshats didn't change your tune till it became obvious the Antarctic wasn't going to support your little tall tale.
And you have the brass to call me the liar? What an asshole you are...
Sea ice is projected to shrink in both the Arctic and Antarctic under all SRES scenarios. In some projections, arctic late-summer sea ice disappears almost entirely by the latter part of the 21st century. {10.3}
"Current global model studies project that theAntarctic Ice Sheet will remain too cold for widespread surface melting and is expected to gain in mass due to increased snowfall. However, net loss of ice mass could occur if dynamical ice discharge dominates the ice sheet mass balance.

It wasn't "predicted" until it became obvious that the ice sheet in Antarctica was increasing, not decreasing:
