onlinelibrary.wiley.com/doi/10.1002/2013GL057782/abstract[1] We present a new stable isotope record from Ellsworth Land which provides a valuable 308 year record (1702–2009) of climate variability from coastal West Antarctica. Climate variability at this site is strongly forced by sea surface temperatures and atmospheric pressure in the tropical Pacific and related to local sea ice conditions. The record shows that this region has warmed since the late 1950s, at a similar magnitude to that observed in the Antarctic Peninsula and central West Antarctica; however, this warming trend is not unique. More dramatic isotopic warming (and cooling) trends occurred in the mid-nineteenth and eighteenth centuries, suggesting that at present, the effect of anthropogenic climate drivers at this location has not exceeded the natural range of climate variability in the context of the past ~300 years.

Here is the recent history of Antarctic sea ice anomalies from UIUC:

Looks like Antarctic sea ice is about to tumble into the mix with the past few years as Weddell lets go of it's 'hard to move' ice. looking at the remaining ice around the continent we might find ice min not as healthy than of late?

Looks like Antarctic sea ice is about to tumble into the mix with the past few years as Weddell lets go of it's 'hard to move' ice. looking at the remaining ice around the continent we might find ice min not as healthy than of late? Changes in the El Niño-Southern Oscillation Index (ENSO), an oscillation of ocean temperatures and surface air pressure in the tropical Pacific, can lead to a delayed response (three to four seasons later) in Antarctic sea ice extent. In general, El Niño leads to more ice in the Weddell Sea and less ice on the other side of the Antarctic Peninsula, while La Niña causes the opposite conditions.earthobservatory.nasa.gov/Features/SeaIce/page4.phpWhat this is saying Graywhale is the sea ice in the Weddell Sea is affected by ENSO in a "delayed" response of a about 3 to 4 seasons. Since 3 to 4 seasons ago we were in La Nina, ice reductions in the Weddell Sea are responding exactly as indicated by the above link. In 3 to 4 more seasons if this El Nino gets off the ground maybe sea ice will increase in the Weddell Sea.

Another epic fail prediction by Mr. Wolf. Tell me again why I should believe any of your dire looks to the future ?

Phydeaux,
You will have to forgive Graywolf. He is a firm believer in CAGW, and can't wait everyone to die. So he can gloat. In the meantime, he consoles himself with AGW pron. Pictures of melting snowdrifts and such.
I know, I know, that is the stupidest thing you've ever heard. Don't tell me, tell him.

BBC reports: Scientists probe Earth's last warm phase Scientists now have a fuller picture of what happened at the poles during the last warm phase on Earth. Known as the Eemian, this time period extended from roughly 129,000 years ago to about 116,000 years before present. The poles were known to have been a few degrees warmer than they are today. But by pulling together more than 40 ice core and marine sediment records, researchers, led by the British Antarctic Survey (BAS), have obtained the most comprehensive assessment yet. It confirms that the Antarctic emerged from Ice Age conditions first. The Northern Hemisphere followed. Link: www.bbc.co.uk/news/science-environment-27110880

Indeed - the actual research paper says the collapse is imminent - around 800 to 1000 years from now. And even that is based on a lot of 'if's and 'could's - so Rigggnnnt obviously time for the Guardian to set the panic in motion. Do you get the feeling that some researchers are scrabbling around for something to panic about now even the slower of the gullibles are realizing that it's not warming?

The desperate newspaper articles have been appearing in the run-up to the EU (and some local) elections here on 22 May.

www.climatecentral.org/news/ocean-winds-australia-heat-17450LONDON — The answer to one of the enduring puzzles of global warming — the apparently sluggish response of the Antarctic continent to rising greenhouse gas levels — may have been settled by Australian scientists. And, in the course of doing so, they may also have solved another problem: the parching of Australia itself
