Not at all what I'm saying, sir. If you can point out where I said anything about anthropologic global warming above, please be my guest. What I'm saying is that you can't pick one side of the globe without paying attention to the rest. I honestly have no clue what's at the "nub" of ice change, those are theories above that can apply to the arctic too, and I know for a fact they have, particularly in the instances of changes in weather. But carry on, please.
Actual data, not "reconstruction" or "projections"...

Ocean around antarctic has been cooling over the past decade.
BTW, the NSIDC Cryo-sat "analysis" is infamous for cherry picking time periods to skew results.
That is actual data above (the 1400 sea ice in the arctic is a reconstruction, but it contains satellite data. Also, the IPCC graph is a projection, yes, but if you see the red line, actual, physical data), so maybe I'm confused as to what you consider "Actual Data."
You seem to be having the same issue as Z, you are only focusing on the Antarctic Records. Why aren't you talking about the records in the Arctic as well? Does sea ice increase in one part of the world give the big picture as to what is happening globally?
As much as I respect blogs for keeping scientist honest, I try not to get my scientific data/information from them. So since we're only talking about the Antarctic, let's look at some science from that area. On you Watt's blog, he uses data to show cooling. The data he is using to show his point is that "Surface" temperatures have been cooling. This publication in a
Nature journal discusses that issue.
Changes in sea ice significantly modulate climate change because of its high reflective and strong insulating nature. In contrast to Arctic sea ice, sea ice surrounding Antarctica has expanded1, with record extent2 in 2010. This ice expansion has previously been attributed to dynamical atmospheric changes that induce atmospheric cooling3. Here we show that accelerated basal melting of Antarctic ice shelves is likely to have contributed significantly to sea-ice expansion. Specifically, we present observations indicating that melt water from Antarctica’s ice shelves accumulates in a cool and fresh surface layer that shields the surface ocean from the warmer deeper waters that are melting the ice shelves. Simulating these processes in a coupled climate model we find that cool and fresh surface water from ice-shelf melt indeed leads to expanding sea ice in austral autumn and winter. This powerful negative feedback counteracts Southern Hemispheric atmospheric warming. Although changes in atmospheric dynamics most likely govern regional sea-ice trends4, our analyses indicate that the overall sea-ice trend is dominated by increased ice-shelf melt. We suggest that cool sea surface temperatures around Antarctica could offset projected snowfall increases in Antarctica, with implications for estimates of future sea-level rise.

Warmer deeper waters you say?
Freshening and warming of Antarctic Bottom Water (AABW) between the 1980s and 2000s are quantified, assessing the relative contributions of water-mass changes and isotherm heave. The analysis uses highly accurate, full-depth, ship-based, conductivity–temperature–depth measurements taken along repeated oceanographic sections around the Southern Ocean. Fresher varieties of AABW are present within the South Pacific and south Indian Oceans in the 2000s compared to the 1990s, with the strongest freshening in the newest waters adjacent to the Antarctic continental slope and rise indicating a recent shift in the salinity of AABW produced in this region. Bottom waters in the Weddell Sea exhibit significantly less water-mass freshening than those in the other two southern basins. However, a decrease in the volume of the coldest, deepest waters is observed throughout the entire Southern Ocean. This isotherm heave causes a salinification and warming on isobaths from the bottom up to the shallow potential temperature maximum. The water-mass freshening of AABW in the Indian and Pacific Ocean sectors is equivalent to a freshwater flux of 73 ± 26 Gt yr−1, roughly half of the estimated recent mass loss of the West Antarctic Ice Sheet. Isotherm heave integrated below 2000 m and south of 30°S equates to a net heat uptake of 34 ± 14 TW of excess energy entering the deep ocean from deep volume loss of AABW and 0.37 ± 0.15 mm yr−1 of sea level rise from associated thermal expansion.

As for the NSIDC data source that you are discrediting, are you bringing that up to discount the NOAA data I provided or was that in regards to the NOAA data that Z provided?
This seems relevant to quote as well:
