A graph showing changes in sea in in the Antarctic from 1979 - 2012
Now there's more ice at South Pole than ever (So much for global warming thawing Antarctica!) by David Derbyshire - Daily Mail
Ice around the South Pole has expanded to cover a record area, scientists revealed yesterday – a month after saying that the North Pole had lost an unprecedented amount of its ice.
Researchers say – rather confusingly – that both occurrences are down to the ‘complex and surprising’ effects of global warming.

Global warming causing Antarctic ice to expand
The ice goes on seemingly forever in a white pancake-flat landscape, stretching farther than ever before. And yet in this confounding region of the world, that spreading ice may be a cockeyed signal of man-made climate change, scientists say.

If the behavior of the poles was reversed, the junk climate scientists would blame it on global warming, and would simply come up with a different ad hoc explanation.

Al Gore did more to bring melting Arctic ice to global attention and concern than anyone. Polar bears became victims and poster animals for destructive human production of CO2. He’s done more than most in creating false ideas and images for his political and economic agenda.
When asked what’s wrong with global warming people usually hesitate for some time, then say glaciers will melt and sea level will rise. That’s probably why Gore made it a major part of his movie. To add emotion to fear the demise of polar bears was threatened. People were easily fooled because few know anything about the Arctic Ocean and the ice conditions.
The Arctic Ocean, a thin line across the top of most world maps is over 14 million km2 (compare US 9.8 million km2). Every year an area equal to the US melts and refreezes and based on a record that began in 1980 (satellite launch 1978 but useable data took 2 years) we presumably can determine the true amount and variations. Gore likely knew people wouldn’t grasp the size of areas involved so added polar bears and the threat of thinning – “thin ice” is a well known danger sign.

One of the major achievements of mankind, over many centuries, has been the development of logical thinking processes. Science now has a well-established process of thinking patterns by which scientists work.
Some pieces of evidence that appear in scientific investigation may seem to be confusing. This is why the rules of logic have to be followed to ensure that there are no false conclusions.
It really amazes me – and also does not surprise me – when, in climate change discussions, completely illogical conclusions take hold in the public mind. It is amazing that basic logic escapes the public or is twisted without anyone seeming to care. On the other hand, it does not surprise me because there are elements in society which want false conclusions to be fed to the public so that they will toe the line of the propagators.
Let me now ponder the issue of claims of melting glaciers and melting ice, in general, that is blamed on global warming.

Much has been written about the record low extent of Arctic sea ice this season. In July it stood at 7.94 million sq km – 2.12 million km below the 1979 – 2000 average, and in September it reached a record low of 3.14 million sq km.
When satellite monitoring of the Arctic ice began in 1979 it was clear that the data had caught a decline already in progress. There is some evidence that the decline may have been taking place since the 1950s, which is before the time that anthropogenic influences came into effect.
In the past few years it is possible that this roughly linear decline may have increased, or have reached a point whereby the behavior of the Arctic ice sheet has changed. 2007 was a record low year for ice extent and it may be that the ice melt-freeze cycle has become noisier. Figure 1.

I decided to graph the AMO vs Arctic Sea Ice Extent vs Antarctic Sea Ice Extent. AMO data comes from NOAA, Sea Ice data comes from NSIDC.
The green is the AMO – Atlantic Multidecadal Oscillation. The red is Antarctic Sea Ice Extent. The blue is the Arctic Sea Ice Extent.
The dashed lines are the liner trends for each.
There are three amazing things:
1) The AMO trend is identical to the Antarctic trend even though the AMO is the sea surface trend of the North Atlantic Ocean! The trend are so close it is hard to see the AMO and Antarctic trends as separate items.

Heralded far and wide as a harbinger of global climate change, this year's record Arctic ice melt has the uninformed climate alarmists celebrating and the more knowledgeable scratching their heads. You see, this summer's ice retreat was predicted by no computer model and few scientists even though it possible. While climate scientists ponder what is wrong with their theories nature has carried on—no fuss, no muss, no drama. Circulation patterns are shifting and living creatures from zooplankton to megafauna are taking the change in stride. What has flummoxed environmental scientists is the simple and now demonstrated fact that successful life forms have a common trait—they are adaptable, something many scientists are not.
That ice in the Arctic has been shrinking during the summer is not news. For the past five years the summer pack ice extent was smaller than previously documented in the 34 year satellite record. This year's massive melt off has occurred under relatively normal weather conditions, with only one strong summer storm to hasten the break-up of the pack ice. But instead of vindicating their computerized prognostications, this year’s record loss has scientists questioning their models. Here is how the quandary was reported in Nature:
Computer models that simulate how the ice will respond to a warming climate project that the Arctic will be seasonally ‘ice free’ (definitions of this vary) some time between 2040 and the end of the century. But the observed downward trend in sea-ice cover suggests that summer sea ice could disappear completely as early as 2030, something that none of the models used for the next report by the Intergovernmental Panel on Climate Change comes close to forecasting.

There is more frozen ocean surrounding Antarctica than has ever been measured. That’s right, after all the shouting and hand waving about the new record low amount of sea ice in the Arctic this summer, Antarctic sea ice has ballooned to a new record high. Mother Nature does seem to have an interesting sense of humor when it comes to the freezing of sea water. Back in 2007 the amount of sea ice left over at the end of the summer in the Arctic at the top of the world was the lowest since the satellite measurements began in 1979.
At the same time the amount of sea ice surrounding Antarctica at the bottom of the world set a new record for the most sea ice. That record large amount of ice got almost no attention, all the talk was about how little ice was left in the Arctic at the end of the melt season. Advance five years later to 2012 and the same thing has happened again. We have record low ice extent in the Arctic and record large ice extent surrounding Antarctica. Who knew that Mother Nature has such a bemusing sense of humor!
