Melting Arctic Ocean sea ice may have been caused by a reversal in the ocean’s circulation that had been going on for about a decade, scientists from NASA and the University of Colorado said.
Rocky Mountain News: ‘Ocean circulation may contribute to warming’

I linked to the nasa version (above) of this in the roundup thread…
Prof David Karoly raised the issue of Artic sea ice loss on ABC Catalyst tonight
http://www.abc.net.au/catalyst/stories/promo.htm
Its disappearing much faster than predicted
And the question is why Gavin…..
David Karoly would say so. He’s on the IPCC gravy train, and is totally committed to the Faith.
What that the fabricating Sid Reynolds. Still waiting on that climate chnage link.
Its disappearing much faster than predicted.
And those who say this, with triumph in their voices, don’t realise thay are admitting that the models are wrong
(He says with triumph in his voice.)
Morison cautioned that while the recent decadal-scale changes in the circulation of the Arctic Ocean may not appear to be directly tied to global warming, most climate models predict the Arctic Oscillation will become even more strongly counterclockwise in the future. “The events of the 1990s may well be a preview of how the Arctic will respond over longer periods of time in a warming world,” he said.
Do the global climate models explain why the Antarctic hasn’t warmed? If anything it’s become cooler ( http://www.unis.no/research/geology/Geo_research/Ole/AntarcticTemperatureChanges.htm ).
If CO2 feedbacks are amplified in the polar regions, why don’t we see rapid warming in the south pole? Last winter the sea ice extent in the Antarctic was nearly a record maximum. It’s pretty clear the GCMs are invalid.
Anthony,
Can you please enlighten me
Where does it say that the GCMs’predict that the Actic Oscillation will become more counterclock wise in the future, and what exactly is the mechanism whereby they/it arrives at this conclusion. Just curious.
Robert – firstly South Pole ain’t the North Pole.
If it was a warm year – you guys would be saying don’t cherry pick. Natural variability is not suddenly suspended due to AGW.
Even more interestingly the models predict such seemingly counter-intuitive behaviour.

There are other anomalous situations like very high warming of the mid-troposphere ove rthe Antarctic. Mainly obs here not models.

We do have good reason to suspect AGW – ozone hole interactions in southern hemisphere climate change http://www.sciencemag.org/cgi/content/abstract/296/5569/895
The Peninsula outside this zone is warming very rapidly.
There a very large amount of change occurring in the southern hemisphere circulation as summarised here

If we’re stuck in reductionism and linearist X-Y plots I’m afraid we’re not going to get too far in any sensible discussion. Read more widely on this complex and interesting issue.
More ‘Its disappearing much faster than predicted’
Malcolm may wish to consider the only other reliable GCM, the one mentioned in “A Review of Sea-Level Change on the Southeast Coast of Australia” which is my old yard stick.
As my associate with the day job passed through the lounge room and caught up with Karoly’s comment regarding non-stop global warming for thirty years regardless of any steps taken to reduce AGW she exclaimed we are already on the curve (upwards). I reminded her that some pommy entrepreneurs had plenty of scope to more their house boats inland as the tide rises (see Grand Design – ABC).
Wollongong people may have a few problems.
The northern Autumn seems to be kicking in well, and in many cases seems like an early winter.
The Anchorage Daily News has reported on an all-time daily snowfall record for Nov. on Monday, of 5″, beating the prev. Nov.record of 3″ set in
1944. Looks like a repeat of last years Alaskan winter, where harbours froze to record levels and all major glaciers thickened and advanced.
Repatee’ many parts of Europe, eg. ‘Record snowfall paralyzes much of Austria. (Austria Today, Nov.12th.)
Well, well, “global warming” indeed.
And, where is the BoM’s summer climate outlook? Have they published it yet?.. We want a copy for Luke to pin up on the frig.!
I don’t know Malcolm, why don’t you spend 10 minutes on google and find out
Paul, I can only assume that your limited and selective summary of what is happening was designed to confuse people. Well done, looks like you have achieved your purpose.
Seeing as its your blog and presumably you wrote it because you had something valuable to contribute, how about you go away give us some more information – perhaps enough for readers to understand why the melting occurred.
Links to the rocky mountain daily just doesn’t do it for me.
Sid – we now by now your middle name is cherry plucking plucker. If you think AGW means natural variation is suddenly suspended you’re more of a tosser than I thought you were.
BTW how’s the fibbing and BoM bashing going. Still waiting for the climate change link which you haven’t delivered. Like the decile analysis you never delivered.
Sid likes to pluck a cooling shrivellng cherry from somewhere in the world and quote it as some sort of proof. Give us a break mate. Take it down the RSL – it ain’t science.
And now the ‘medicine men’ at the CSIRO have come up with another one of their computer games that show that rainfall in Australia is going to fall by 10% in the next 30 years. Really! Primary producer orginasitions now just laugh at them. Many rural policy makers now take little notice of the CSIRO.
Yes Sid, people on 20% and 0% allocations are in hysterics just laughing about this whole ‘climate change’ thing…
And Sid that BoM web link was where again?
Yes Anthony, many of them do laugh at ‘this climate change thing’. But they don’t laugh at the drought, which is actually real, and hurting many.
These are probably Sid’s imaginary friends like imaginary links.
The reason for sudden Arctic ice melting is clearly reported in Nature – see Slingo et al Nature 1 November page 27 – it is due to abnormal wind patterns. They say “These Arctic wind
anomalies were part of a global-scale pattern
of highly unusual circulation this summer,
the causes of which are as yet unclear”. Yet another of the myriad of unexplained aspects of climate which make long term forecasting impossible.
The same mafia that Mottsa wants a big fat carbon credit from. What hypocrisy.
A NASA report released on Wednesday debunks a “global warming” myth relating to loss of arctic ice, claiming that it is mainly due to a decadal pattern which is about to change.
Will be interesting to see whether the media reports this!
Meanwhile, many ski resorts are opening early this year in Europe and North America, because of the extremely heavy early snowfalls. Latest to do so are several resorts in B.C. where resorts already have over 4ft. of snow on the ground, extremely unusual for mid Nov. And it is still snowing quite heavily in the B.C. resort areas.
“Receding snowlines because of AGW”.. Ho hum.
Wow Sid, its amazing you know so much about this stuff when you haven’t either read or understood what you are writing about.
Yep, melt is due to a decadal pattern. Any idea what its called? Any idea how it is predicted to be affected by warming?
Gee, less ice, more snow. 1+1=2 after all
My post above refers to the same NASA report which Paul has posted in this thread above, but through a different source.
Anthony doesn’t like newspaper links like the Rocky Mountain News, but Arnost has given him a NASA link, and I’ll give him another.
