On the 22nd September I put forward a prediction that this years Arctic sea ice extent would return to anormal level by December. It was never meant to be a prediction that would set the world on fire:) but as you will see from the above image taken today at ijis.iarc.uaf.edu/seaice the Arctic sea ice extent HAS returned to NORMAL! However this result has given more questions then answers, and that is......how can the 2006 Arctic sea ice extent, that had peaked in September 2006 as one of the most covered ice areas end up with having one of the worst results for the recent November and December periods.
What was it about the level of CO2 in November/December of 2006? Why did the media not pick up on this in the same way they did for September 2012? Sadly we will never know the answer to these questions.
I could be wrong on this but I think the clue is in the temperature of the Ocean currents and from what NASA has gone onto say it's also to do with Arctic storm force winds, this then, points to CO2 as having NOTHING to do with Arctic sea ice melt!
Meanwhile....although this years Arctic sea ice extent HAS returned to normal, as predicted, will the MSM make a point of mentioning this happy event...sadly I think not! The Arctic sea ice extent returning back to normal is not a news worthy event, it would mean that the Main Stream Media would have to say CO2 does not melt ice afterall

What follows below is a press release from the British Antarctic Survey, read it here
You’ll note as you read the press release, the science that applies at the South Pole mysteriously disappears at the North Pole. Winds are causing the the sea ice expansion down south, scientists claim, but of course they couldn’t possibly cause shrinkage up north.
I’ve added some emphasis to some of the text below. (P. Gosselin)
Press Release – Why Antarctic sea ice cover has increased under the effects of climate change
The first direct evidence that marked changes to Antarctic sea ice drift have occurred over the last 20 years, in response to changing winds, is published this week in the journal Nature Geoscience. Scientists from NERC’s British Antarctic Survey (BAS) and NASA’s Jet Propulsion Laboratory (JPL), Pasadena California explain why, unlike the dramatic losses reported in the Arctic, the Antarctic sea ice cover has increased under the effects of climate change.

Posted at Among the ice charts I peek at every day is the one from DMI (Danish Meteorological Institute).
Today there was a new Sea Ice Extent Chart with this text at the bottom:
The plot above replaces an earlier sea ice extent plot, that was based on data with the coastal zones masked out.
That implied that the previous sea ice extent estimates were underestimated.

The AMO drives Europe's climate on a multidecadal time scale.
Climate change alarmists point to the past several decades of European weather to reinforce their claim that global warming has the continent in its grip. A new report shows that this recent warm spell is nothing abnormal or unprecedented—during the 1990s there was simply a return to conditions present during 1931-1960. The reason for the shift is warm ocean temperatures that are, in turn driven by variation in warm ocean currents from the tropics. The instrumental record shows that, relative to the average temperature of the rest of the world’s oceans, the temperature of the North Atlantic Ocean has fluctuated between anomalously warm and anomalously cool phases, each lasting several decades at a time. Palaeoclimate records suggest that similar variations extend much farther back in time. The observed pattern of multidecadal variation in North Atlantic sea surface temperatures (SSTs) has become known as the Atlantic Multidecadal Oscillation (AMO).
Climate change happens in cycles both long and short. The most dramatic long cycle that humans have experienced is the alternating ice age phenomenon of glacial and interglacial periods. Over the past 800,000 years or so, the world freezes for 100,000 years and then suddenly thaws for 15-25,000 years. Among the best known short cycles are the alternating El Niño/La Niña conditions in the Pacific, which gets blamed for bad weather in North America and failed monsoons in Asia. There are, however, a number of intermediate cycles that function on scales of decades to hundreds of years.

Your Newsnight segment on Arctic sea ice (BBC2 TV, 8 September 2012) featured a “scientist” who said ice loss since a high point in 1979 would cut the Earth’s albedo and, by this feedback, cause warming equivalent to 20 years’ global CO2 emissions.
On the IPCC’s current central climate-sensitivity estimates, 20 years’ CO2 emissions would only warm the Earth by ¼ C°. But since the IPCC’s first projections in 1990, temperature has risen only half as fast as predicted: so make that just ? C°.
The glaciologist the programme relied on got the math wrong. Ignoring the growth in Antarctic sea ice since 1979, as the programme unwisely did, the loss of 2.5 million km2 of Arctic sea ice (measured as the linear trend on the NSIDC data) will warm the Earth by only 1/20 C°, and only then if the ice loss is permanent. Halve that to allow for the compensating effect of record Antarctic sea-ice growth: say, 1/40 C° of global warming, equivalent to just 2 years’ CO2 emissions on the IPCC’s current projections, not 20 years’ emissions.
Some relevant points your programme did not make:

Earlier this month I posted a Royal Society of Chemistry competition that concerned a very simple question and had a very complicated answer:
RSC offers £1000 for explanation of an unsolved legendary phenomenon - rsc.org
Why does hot water freeze faster than cold water?
It seems a simple enough question - yet it has baffled the best brains for at least 2,300 years.
•Aristotle agonized over it fruitlessly in the fourth century BC
•Roger Bacon in the 13th century used it to advocate the scientific method in his book Opus Majus
•Another Bacon, Francis, wrote in his 1620 Novum Organum, that "slightly tepid water freezes more easily than that which is utterly cold" but could not explain why
•Descartes was defeated by it in the 17th century AD
•Even perplexed 20th and 21st century scientists and intellectuals have swarmed over it without result

Within just a few days in September, Arctic sea ice extent reached the lowest minimum ever recorded by satellites since 1979, while at the same time, Antarctic sea ice reached the greatest extent ever recorded.
In my post “The Arctic-Antarctic seesaw” I explained how natural forces work to produce these phenomena. In my post “Challenge to the Arizona Daily Star – get the facts” I accused the Arizona Daily Star of content bias because they prominently reported the Arctic minimum, but until now, did not report the Antarctic maximum.
Now, 21 days after the Antarctic maximum, the Arizona Daily Star has reprinted an AP article which attempts to spin observations to fit AGW global warming theory: “Experts: Global warming means more Antarctic ice.” The article author is Seth Borenstein, long known for bad reporting on climate change. With global warming media bias, it’s “heads I win; tails you lose.”
The AP/Star story says, “It sounds counterintuitive, but the Antarctic is part of the warming as well.” Really? Was this a surprise to some climate scientists and their models? Let’s see what the climate models said according to a study in the Journal of Climate:
