I’ve been so impressed with the recovery thus far for Arctic sea ice, I’ve added a live icon for it in the lower right under the global satellite image. Just click on it to get a full sized graph like above.
Watch the red line as it progresses. So far we are back to 2005 levels, and significantly ahead of last year at this time.

I can’t even imagine why anybody would expect that the Arctic sea ice and the Antarctic sea ice would in any way be comparable.
The antarctic is mostly water, and the arctic is mostly land. The ocean circulations can’t be anywhere like mirror images.
One look at the NOAA (if you can find it) annual CO2 pole to pole graph (which unfortunately only covers ten years) to sea that the earth is totally assymmetrical north to south.
The 6 ppm Mauna Loa annual CO2 cycle is almost zero; maybe less than 1ppm at the south pole, and about 18 ppm p-p at the north pole.
So I would not expect any sort of ice trends in the arctic to suggest something similar should occur in Antarctica at the same time.
Not that I am suggesting a CO2 -ice link; I’m just pointing out they are two different animals.
Meanwhile for Manfred’s edification; all of the popular kayak expeditions to the north pole have been cancelled for the season for lack of interest.
Spangled,
How do you figure? Just eyeballing the NSIDC graphic I think ti shows right around 7 million sq. Km, not 4.5> It showed around 4.5 million sq. Km at it’s lowest extent this summer
wasnt antarctic ice maximum a Big Deal last year? not so this year? hmm
If you subtracted out the quasi periodic seasonality, I wonder if you’d see an overshoot (or as the case may be, undershoot)? If so, that is quite disturbing.
I wonder what a graph of Arctic ice plus Antarctic ice would look like.

I think you have it around the wrong way – the Antarctic is mostly land while the Arctic is mostly ocean.
Thanks, Mike, for the snow coverage data. Is that information available at a single location for global figures, or even any other significant ones — such as Russia or China?
OT, UAH site appears to have a fair-sized problem. Anyone know what’s going on there? http://discover.itsc.uah.edu/amsutemps/ It almost looks like it was hacked 🙁
George E Smith:

I believe it’s the other way around. Antarctica is a continent and therefore mostly land. The Arctic Ocean is mostly water.
So I would not expect any sort of ice trends in the arctic to suggest something similar should occur in Antarctica at the same time.
Well, of course. It’s entering summer in the SH and winter in the NH.
Another ice map:

NSIDC (accidentaly) confirms that next year will see a huge increase in the amount of multi-year ice.

All of the ice currently shown as first year ice (blue) will be second year ice (purple) going into next summer’s melt season.

Something like http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/global.daily.ice.area.withtrend.jpg
Spurious ice:
The ice map pointed out by Glenn:http://iabp.apl.washington.edu/maps_daily_ncepice.html
shows spurious ice in the Baltic sea, at the coast of Norway and even at the Irish coast. Ladoga lake near St. Petersburg, Russia, seems to be completely frozen, which is simply impossible at this time of the year.
Looking at:http://nsidc.org/data/seaice_index/images/daily_images/N_daily_extent_hires.png
you also see spurious ice in the Baltic sea and near the island of Sachalin near Northern Japan.

The Boston Globe reports that the Little Ice Age (which didn’t exist according to Mann) was due to melting ice in the Arctic.

The melting Arctic ice must have been caused by all the Londoners fleeing the frozen Thames towards the warm Arctic in their Hummers.
The stupidity of AGW types seems to know no bounds.
Remember that the average 1979-2000 (which I don’t know why it’s important; just as I also don’t know why it’s bad if ice melts) is above the ice extent of the last 7 years. If baby ice this year gets larger than the last 7 years we’ll be more close to — but not necessary above — 1979-2000 average than we’ve been the last 7 years.
It would be interresting, and a jump from the next smallest extent (2008) to above 1979-2000 average within monthes, or a year, would be kind of exceptional… or?
Anyway, it would be good at the Kyoto negotiating!
Werner, your second link, i cant make it work, something missing?
btw: The first link: Im trying to understand its content, because it says that there should be ice in Danish waters as well, in “kattegat”, and… this i believe is not the case. So why do they show these white dots?
Patrick Henry:
Notice the nominative determinism of the author of that ludicrous Boston Globe article!
Crosspatch
It is important to know and understand that the graphs on Cryosphere Today shows Sea Ice “Area” while the other sites, NSIDC and IARC-JAXA, show Sea ICE “Extent”
There IS a difference between those two measures…
Tom in Texas (19:49:14) Cryosphere Today has the graph you seek, at least the anomaly thereof.

As I pointed out earlier, a rapid increasing in sea ice after a summer melt spike down as we saw in 2007, is what you would expect if the primary cause of Arctic ice melt is soot. Dirty low albedo ice replaced by clean high albedo ice, and consequent cooling with more ice formation.
Not news. Only when the ice melts is it news. The arctic is supposed to be refreezing now.
Arctic/Antarctic sea-ice since 2005 (I don’t think their data is quite up to date):

“I wonder if the media will be reporting this?”
Yeah, that’ll make a great headline “Arctic sea ice freezing in October”
Move along…nothing to see here…
