Do you suppose Antarctic sea ice will reach Terra del Fuego and close the Strait of Magellan?

[h=2]NASA Announces New Record Growth Of Antarctic Sea Ice Extent[/h] Posted on October 22, 2013 by Anthony Watts
Researchers have measured a new record for sea-ice extent in the Antarctic. Why the white splendour is extending there while it is rapidly disappearing in the Arctic is a mystery.

Antarctica: The extent of sea ice (white) reached a record on 22 September. The yellow line shows the median of 1981 to 2000. Ice shelf is shown in gray.
Whenever the ice at the North and South Pole is mentioned, it is mostly in the context of melting ice triggered by global warming. However, the sea ice in Antarctica – in contrast to that in the Arctic – has proved to be remarkably robust. New measurements have now confirmed that. As the U.S. space agency NASA announced, the sea ice in the Antarctic has extended over an area of ​​19.47 million square meters at the end of September. That is the highest since measurements began in 1979.

Not terribly relevant, because that's a graph of mass, not extent.

The antarctic has seen a growth in ice area, but judging by the chart Gimme presented, what you're seeing is a growth in widespread-but-very-thin ice, while overall ice volume has actually decreased.

When discussing "is ice melting," I'd personally go with volume over area!

Although judging from this quote in WUWT's article, you're probably correct that in the last year or two there has been a small gain in antarctic ice volume
“The tiny gain in Antarctica’s ice is an interesting puzzle for scientists,” said NSIDC lead scientist Ted Scambos. “The rapid loss of ice in the Arctic should be ringing alarm bells for everyone.”

To answer your question in the OP, no, I wouldn't expect ice extent to grow far enough to shut down those areas. But I'm just some jackass on the internet, so what the hell do I know? :D

We shall see. The OP question was tongue-in-cheek, but thanks for the reassurance.:2wave:

When the real world doesnt play ball they just invent an answer for everything out of kilter with the gospel dont they ? ;)

I was wondering that myself. I wonder who has records of the actual mass of ice on the Antarctic continent and how this was compiled.

PEople talk about global warming still and I don't buy it. Climate change? Yes. Global Warming? No. People can prepare all the stats that they like. I know what is going on in the environment around me. It is everybit as cold and windy in the winter as it used to be and the summers are no hotter and longer than they used to be. A touch here and there, sure? But both ways. We had a shorter winter this year for the first time in a long time but now it is being followed with a really wet, cloudy and chilly spring.

Some just like to wave a shroud and if that shroud helps expedite their particular political worldview for them so much the better. It doesnt matter that behind it the emperor has no clothes :(

Warm Ocean Causing Most Antarctic Ice Shelf Mass Loss | NASA

Um, you have it backwards....the climate is warming the oceans, the oceans are causing Antarctic ice mass loss.

Still need a wetsuit. Still cold as hell during winter. Snowed on the beach the past two years for the first time in over forty years. And not to be rude but I don't care about Antarcitic ice loss. Just new real estate to live on.

The published studies of the main Antarctic ice sheets and the ESA Cryosat satellite specifically designed to measure such anomalies disagree

No it does not disagree. Antarctica is split between east and west, the cited Cryosat data focused on a tiny portion of the east and did find an increase in height of the land ice sheet there:

...but:

There is variation between regions within Antarctica (Figure 2, top panel), with the West Antarctic Ice Sheet and the Antarctic Peninsula Ice Sheet losing ice mass, and with an increasing rate. The East Antarctic Ice Sheet is growing slightly over this period but not enough to offset the other losses. There are of course uncertainties in the estimation methods but independent data from multiple measurement techniques (explained here) all show the same thing, Antarctica is losing land ice as a whole, and these losses are accelerating quickly.​

Is Antarctica losing or gaining ice?

I can only restate that current published literature disagrees with your cartoonist blog graphs for both East and West Antarctica. Why is it so important to you that these must be wrong ?

A new record: the most sea ice in Antarctica in 30 years by extent and by volume

Posted on October 24, 2013 by Anthony Watts
Translated by Google from this press release in German at the Alfred Wegener Institute in Germany:
Never so much sea ice at Antarctica in the last 30 years
In light of global warming, it seems paradoxical that the sea ice cover of the Southern Ocean has covered a larger area in the past month than in the last decades. Only in the mid-70s was observed a similar expansion.
Average sea ice extent in September (1973-2013) with trend line Seasonal variability of sea ice extent (as at 13.10.2013) The means were 19.48 million in September 2013 square kilometers, an area once covered more than 50 times larger than Germany with sea ice. The absolute maximum of 19.65 million square kilometers was reached on 18 of September. Although this maximum in the ice-covered surface can not be equated with a maximum of the total volume or mass, suggest that sea ice physicist Marcel Nicolaus and Stefan Hendricks from the Alfred Wegener Institute (AWI) “This winter there is in Antarctica as much ice as long gone, if it has ever been since the beginning of the regular satellite observations ever so much sea ice.”

That is a very interesting headline seeing as how Watts doesn't seem to quantify any increase in volume...
