Not only has Antarctic sea ice not changed, but land based ice is expanding according to NASA study.
Antarctic Sea Ice Has Not Shrunk In 100 Years | Climate Depot
Well, thats a fascinating take by the oil and gas lobbyist who runs that blog.
Of course, if you go to the original paper, which you have to go several links in to find, you'll see the abstract says this:

Abstract. In stark contrast to the sharp decline in Arctic sea ice, there has been a steady increase in ice extent around Antarctica during the last three decades, especially in the Weddell and Ross seas. In general, climate models do not to capture this trend and a lack of information about sea ice coverage in the pre-satellite period limits our ability to quantify the sensitivity of sea ice to climate change and robustly validate climate models. However, evidence of the presence and nature of sea ice was often recorded during early Antarctic exploration, though these sources have not previously been explored or exploited until now. We have analysed observations of the summer sea ice edge from the ship logbooks of explorers such as Robert Falcon Scott, Ernest Shackleton and their contemporaries during the Heroic Age of Antarctic Exploration (1897–1917), and in this study we compare these to satellite observations from the period 1989–2014, offering insight into the ice conditions of this period, from direct observations, for the first time.
This comparison shows that the summer sea ice edge was between 1.0 and 1.7° further north in the Weddell Sea during this period but that ice conditions were surprisingly comparable to the present day in other sectors.

In other words, it looks about the same, except it had a larger extent in one part - and that larger extent was somewhere between 1 degree and 1.7 degrees, which translates into about 70-120 miles farther north. Of course, this is only a tiny peice of the Antarctic, so what the actual conclusion of the article shows is that if there has been any change at all, the sea ice has retreated about 100 miles South.
Now, of course, the sea ice isnt that big of a deal - it seems that as the water temp gets warmer, the currents are allowing increases in sea ice around the Antartcic. The concern is the ice shelves and land glaciers. I think your oil and gas lobbyist blogger forgot to point out that these ice shelves are in rapid retreat, as shown in this study:
Widespread, rapid grounding line retreat of Pine Island,
Thwaites, Smith, and Kohler glaciers, West Antarctica,
from 1992 to 2011
And the ice shelves have been breaking and dumping
spectacularly large pieces of ice into the sea and as has been pointed out by scientists, this breakup has been
accelerating the speed in which glaciers are moving toward the ocean.
I'd advise you to get your science from scientists next time, instead of relying on Mark Morano, a paid shill for the energy industry.
