I’ve seen hints in some of the GHCN temperature data that the south pole / hemisphere gets hot when the north gets cold, and the other way ’round too. But the Southern Hemisphere data can be a bit slim over long time windows. Not much land ‘down under’ and what there is tends to be the frozen Antarctic; so not a lot of data from the 1800s and even the early 1900s are sparse.
Yet 1934 was very hot in the USA midwest, and IIRC, it was not hot in Antarctic data (but a different decade was – yet the Antarctic data are very spotty by station, so it takes some interpolation / guessing…)
Right now, lots of “news” is about the North Pole having very low ice levels. But the Warmista Folks are ignoring the record ice levels in the Antarctic. I think these two are related. That it isn’t an accident that one is warm when the other is cold. It needs a good “Dig Here!”, and any pointers to anything already done would be ‘nice to have’.
I find it interesting that we apparently have this “bipolar” relationship going on. On years of far lower than normal record lows in the Arctic 2007/2012, we have record highs and near record highs in the same years, 2007/2012.

Antarctic Sea Ice Sets Another Record
Antarctic sea ice set another record this past week, with the most amount of ice ever recorded on day 256 of the calendar year (September 12 of this leap year). Please, nobody tell the mainstream media or they might have to retract some stories and admit they are misrepresenting scientific data.
NPR failed to mention anywhere in its article that Antarctic sea ice has been growing since satellites first began measuring the ice 33 years ago and the sea ice has been above the 33-year average throughout 2012.
The update includes a quote of Anthony Watts and a link to an article on WUWT. Then goes on to an interesting NASA quote:
Interestingly, a new NASA study finds Antarctica once supported vegetation similar to that of present-day Iceland.
“The southward movements of rain bands associated with a warmer climate in the high-latitude southern hemisphere made the margins of Antarctica less like a polar desert, and more like present-day Iceland,” a co-author of the NASA study reports.
So if they move in opposition with major shifts of climate, might they also move with smaller shifts as well?
An Example of Antarctic Cold
This article has an interesting story about the cold in Vostok. Not a record, but close to one, and way below “normal”:
Antarctica Site Posts Near-Record Cold
September 19, 2012; 7:23 AM
This month, Russia’s Vostok station has registered some remarkably low late-winter temperatures, even for the coldest known spot on Earth.
As of Sept. 18, the average temperature for the month so far was -73.0 degrees C (-99.4 F), or -6.7 degrees C (-12.0 F) below normal.
Three nights have have seen the temperature break through the minus-80-degree mark (-112 F). Coldest of these, on Sept. 15, bottomed at -84.2 degrees C (-119.6 F).
The station’s lowest September temperature on record is -85.6 degrees C (-122.1 F), the Vostok Wikipedia entry says.
The average temperature on Sept. 15 was -78.5 degrees C (-109.3 F), which is 12.3 degrees C (-23 F) below normal.
So it was within 1.4 C of the lowest on record. This is “Global Warming”? Whatever is going on isn’t “global” and it isn’t “warming” in Antarctica.
My thesis would be that just as there are many other ‘teleconnected’ oscillations (such as the AMO / PDO / AO ) that there could well be some kind of polar oscillation. But has it already been identified and named? Am I just “catching up”? I tried a few different search terms, but didn’t find any decadal scale cycle identified. Then again, AO and related tend to dominate the results, so it might be that I just don’t know the “magic cookie” to pop up the proper name.
Has a graph of the Arctic Oscillation and says it is teleconnected with the Antarctic Oscillation, but doesn’t show the relationship. At the moment it is ‘high’ and the red lines are the predictions.
The similar page for the AAO Antarctic Oscillation doesn’t have such a graph.
Instead it shows a polar view with a very blue south pole, but large red blobs out to sea from Antarctica.
But those are relatively fast changes. Not things that change over decadal time scales.
So that’s all I’ve got for this posting. Just a question. Does anyone know? Has anyone looked? Might it be cold and frozen in Antarctica BECAUSE it’s warmer and melted in the Arctic? (Or vice versa). Given that past data down south is so spotty, could we ever really know?
Well, no sooner post this and run off to read some WUWT, but discover a similar speculation / article there:
So I wonder what caused us to have the same ideas at about the same times… Odd, that.
