The expansion of sea ice in the Antarctic is a mediate consequence of global warming. Warm water freezes faster than cold water. What matters is the melting glacial shelf ice.
However, a conclusion of the Barnes study is that the recovery of the stratospheric ozone layer – now underway – may slow/delay Antarctic warming and ice melt.
Ultimately, it’s apparent the relationship between ozone depletion, climate warming from greenhouse gases, natural variability, and how Antarctic ice responds is all very complicated. In sharp contrast, in the Arctic, there seems to be a relatively straight forward relationship between temperature and ice extent.
Does anyone EVER read the links? Pretty weak sauce effort OP.
Not ONE mmgw nut has ever explained why the mile thick glaciers which covered most of Europe and North America 12,000 years ago melted and receded.
This. Our planet has warmed and cooled countless times before the first caveman discovered fire. We're looking at a mere sliver of climate trends and extrapolating that data to reach preconceived conclusions.
Why? Because just as there are companies making billions from fossil fuels, there's also companies that are poised to make billions in green energy and they're very well connected to the current administration. Global warming hysteria is the perfect means to get any laws or regulations they want passed under the guise of environmentalism. Objecting to these laws brands you as anti-science, pro-pollution and in the pocket of big business. But its all big business, its just that one side has much better spin doctors than the other.
Green laws and regulations put US companies at a serious disadvantage when competing against countries like China and India who don't have these restrictions. Before we make these kinds of decisions, we need to be sure they're needed for humanity and not to simply fill someone's pockets.

And if climate change turns out to be a big conspiracy that involved basically the entire scientific community we'll have gone and cleaned up our air, water and greatly improved public health for nothing!
I don't mind warm, but the alarmists claim warm weather will make ice melt, which rises sea levels. That can't happen since the ice is NOT melting.
Melting of sea ice does NOT cause a rise in ocean levels! Anyone can do a simple experiment demonstrating this point. Put a couple of ice cubes into a glass of water, mark the level of the water on the glass. Go back a few hours later when the ice has melted and note whether or not the water level has changed.
And yes I know that around Antarctica sea ice is mostly the result of land ice moving into the surrounding water as a result of glaciers. Arctic ice, however, is mostly over water, with no land involved.
The cycle of ice formation and melting is the result of precipitation in the form of rain and snow in the polar regions. And, of course, the numbers of icebreakers chopping up the sea ice while ferrying the idle rich to give them an opportunity to stand on the North Pole.
PS given this reality, sea levels are constantly rising and falling, depending upon the contributing factors. During the last great glaciation (ice age) ending roughly 12,000 years ago, sea levels were roughly 300 feet lower, at least according to the displays at the SF Bay Model, in Sausalito, CA. Which makes sense because so much water was tied up into the ice sheets that covered so much of the world.

Melting ice over land would cause it to rise, but the ice on land does not seem to be melting.

To the scientifically illiterate, last years polar vortex proves there is no climate change.

Say what? Do you have PEER REVIEWED studies which PROVE this?
Or even a simple self performed experiment in which you place a bowl of very hot water and a bowl of very cold water into your freezer and note which one freezes into a solid bowl ice first?
My own theory is that the melting shelf ice has changed the salinity of the Antarctic ocean slowing currents and resulting in an increase in sea ice. This is the critical concern in the Northern Hemisphere where the decrease in ocean salinity is causing slowing in thermohaline circulation.
