If you want to visit Antarctica, don't go to Anthony Watts for directions. This is where he says it is:
Warming doesn’t seem to be a problem when you look at the satellite data for the Antarctic continent, in fact, there is a slight cooling:
Anthony Watts has the power to move a continent
This is his "proof" of the slight cooling of the continent of Antarctica:

This is how far he's managed to move the continent:

(If you're on the home page, click read more to find out why Anthony took it on himself to move an entire continent. Plus there's lots, lots more...)
As for why Anthony decided to move Antarctica, well it's because he took umbrage at scientists explaining why the winter sea ice around Antarctica is expanding. At the ABC they wrote:
The ice is generated in what scientists refer to as "sea ice factories" or polynia - areas of the ocean surface where currents and wind patterns combine to generate sea ice.
"As soon as sea ice is produced in these polynias it is actually transported away from that so more sea ice can be produced," Dr Lieser said.
As the area covered in sea ice expands scientists have said the ice on the continent of Antarctica which is not over the ocean continues to deplete.
CEO of the Antarctic Climate and Ecosystems CRC, Tony Worby, said the warming atmosphere is leading to greater sea ice coverage by changing wind patterns.
"The extent of sea ice is driven by the winds around Antarctica, and we believe that they're increasing in strength and part of that is around the depletion of ozone," he said.
Yes, the extent of sea ice is being driven by wind. The wind is changing and probably increasing in strength in part because of the depletion of ozone and in part because of global warming. But what Anthony Watts wrote was:
Ah ya gotta love the ABC of Australia, they’ll find a way to keep the meme alive no matter what, as reported in WUWT two days ago, they found this guy to give a “the warming is wot dun it” quote with their story about the record level of Antarctic sea ice.
Anthony ignores the role of ozone depletion. Well, he's an ozone hole denier, so that should come as no surprise.
Update: There is an excellent Catalyst video (with transcript) on the ABC website, featuring Mark Curran and Ian Simmonds, and discussing and illustrating the reasons for the sea ice expansion, together with evidence of past changes. It's well worth 8 minutes and 47 seconds from your day. H/t John Byatt. [Sou, 11:22 am Tues 16 Sept]
There was a good article in National Geographic earlier this year, which featured Richard Alley and Eric Rignot. It said in part:
Changes in wind patterns around Antarctica are considered the most likely source of the warmer water, says Alley. As to why the winds have shifted down south, "global warming, the ozone hole, and natural variability are all suspects—the most likely answer being that all three played a role."
Eric Rignot, a glaciologist at the University of California, Irvine and NASA's Jet Propulsion Laboratory, agrees.
"The key is the recent change in ocean circulation," says Rignot, who was the lead author of a paper on melting Antarctic glaciers appearing in Geophysical Research Letters, a journal of the American Geophysical Union.
"Warm waters are already [present in the area] and are being pushed to a different location."
Antarctica isn't cooling
Anthony puts up this image and insists that Antarctica isn't warming, except for peninsula (more on that below).
Look at the legend. All but a bit in the centre and a patch in West Antarctica is getting warmer. (The white around the outside is the ocean, not land, presumably sea ice.)
Yet I don't think that chart is very accurate. It's from 1957 to 2006.
This is from Figure 10.7 of the IPCC report. It shows overall warming too (HadCRUT4 black line), but I know temperature trends are different in different parts of the continent:
Antarctic ice is melting from the "waste heat from the little warm pockets of humanity"
You'll love this next bit. Anthony goes on to say that:
There is some warming along the Antarctic peninsula, but that seems to be related to wind and ocean patterns there, along with possible waste heat from the little warm pockets of humanity where the temperatures are measured. The Antarctic peninsula has the highest concentration of people on the continent, mainly because conditions are much less harsh there.
"Waste heat from little pockets of humanity". Ha ha ha. Do you want to know the population of the Antarctic Peninsula? Wikipedia puts the entire continent's population as:
Several governments maintain permanent manned research stations on the continent. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 0.00007 inhabitants per square kilometre (0.00018 /sq mi) and 0.00035 inhabitants per square kilometre (0.00091 /sq mi) at these times.
Say, for argument's sake, that all 1,000 people in winter and all 5,000 people in summer clustered on the peninsula, which they don't of course. That would make the population density around 0.0019 persons per sq km in winter and 0.0096 persons per sq km in summer. Compare that with Hong Kong, which has a population density of 6,544 persons per sq km.
What does this remind you of?
Does Anthony's "waste heat from little pockets of humanity" remind you of anything? Some of you will immediately think of the classic WUWT article (archived here). Anthony put up a picture:
|Source: WUWT who got it from the website of Don Hilger and Gary Toth|
The picture is a stamp from 1997. Anthony didn't say who he pinched it from but it's a fair guess that he "borrowed" it from the philatelic collection of Don Hilger and Gary Toth on their page of Stevenson screen shelters on postage stamps. The image is the one marked "Australian Antarctic Territory L102 maxi"
Now that's not the funny bit. No, the really hilarious part is what Anthony wrote just above the photo:
Regarding that rapid warming of 2C in the last 50 years, just remember that most weather stations in the Antarctic are near humanity, and humanity requires warmth to survive. For example:
And then underneath the photo he wrote:
The Antarctic peninsula is the most populated place in Antarctica.
So he's saying the Antarctic Peninsula has UHI disease!
Setting a bad example
Wait. There's so much more. The "for example" wasn't an example at all. In the comments, Antarctic researcher Ian wrote (my large bold italics):

I guess I owe the world a humble apology for personally contributing so much to the urban heat island in Antarctica, and hence to misinterpreted climate records.
The badly sited meteorological screen in your photo is at an Australian summer camp in the Northern Prince Charles Mountains, near Mt Jacklyn – in the background.
Temperatures measured here were for local information of pilots and field parties only – it is useful to have an idea of how many layers of clothes to put on before exiting your Antarctic shelter. Temperatures here were only measured for less than 2 months over a couple of seasons and have NEVER been used for any climate record.
This photo was taken in the 1988/89 austral summer when I, and a colleague Andy, lived in the UNHEATED shelter nearest to the meteorological station.
I didn’t realise that I was so hot that my body heat could influence temperatures measured on the Antarctic Peninsula, thousands of kilometres away. It must have been Andy!!!
Don't go away yet. There is still more. Glenn Tamblyn piped up with:

Correct me if I am wrong here but, as an Australian, I was not aware that Australia had any bases in the Antarctic Penninsular – you know, south of South America and all that. And the photo you show has been identified by Ian as being from a very long way away from the Antarctic Pennisular.
When I mouse over the photo it is labelled as australian_antarctic_postcard.jpg. And it even has a stamp with the ANARE logo on it (Australian National Antarctic Research Expedition).
So what on earth has that photo got to do with a post about the Antarctic Penninsular?
Then when commenters here started trying to dissect the ‘station quality’ issues of this site, you didn’t even mention that the photo has zero to do with the subject of the post.
That perhaps going into the detail of how elevated the met station in the photo might be has zero relevence since the station isn’t in the Antarctic Penninsular, isn’t part of any climate record, and only operated few a few months a year as a service to Antarctic pilots.
Did you point this out to any of the commenters here? Why not?
To which Anthony replied:
REPLY: It illustrates that weather stations in Antarctica and heat generating/using humanity are in proximity, the same thing happens in the Arctic, such as at the DEW line stations, where they’d “make up temperatures” rather than brave going outside at times.
Not hard to understand really, people don’t place the weather stations so far away from the huts that they have to risk death to get a reading in subzero temperatures and white out blizzards. – Anthony
Oh my. Anthony reckons that a weather station that was "never" used for any climate record, which was located thousands of kilometres from the Antarctic Peninsula, is in proximity to "heat generating/using humanity!!!
If you want to see the power of "heat generating humanity" in Antarctica, here it is, courtesy of Anthony Watts:
Oh, there is so much to make fun of in that thread. It made the rounds of climate hawks before Anthony shut it down. And some of them couldn't resist. I'll just pick one more:
mandas asked if it was UHI.

“….Regarding that rapid warming of 2C in the last 50 years, just remember that most weather stations in the Antarctic are near humanity, and humanity requires warmth to survive….”
So you’re saying that warming in the Antarctic is due to UHI????
Keep it up Anthony, the farce is strong with this one.
REPLY: No dumkopf, there is no UHI since there’s no “urban” in Antarctica. That’s your made up farce. I’m saying that weather stations, like the one shown, are almost always next to human habitation where it is warmer. Really how hard can it be to understand this, especially with a photo?- Anthony
Umm, Anthony - you dumkopf, you really should read your comments before making such an idiot of yourself. Plus, what he's really saying, since climate records are anomalies and trends, is that humans get hotter and hotter and hotter and hotter and hotter and hotter and never stop getting hotter. And all that body heat passes right through the icy winds of Antarctica, right through the Stevenson screen (3,000 plus km away) and land right on the thermometer. Now you won't find that happening in an urban heat island in the middle of a city!

“The extent of sea ice is driven by the winds around Antarctica, and we believe that they’re increasing in strength and part of that is around the depletion of ozone,” he said.
The depletion of ozone (the ozone hole) was first discovered during IGY 1957. Sure took a long time to see the effect on the wind!
Nope. NASA states that in 1956 the British Antarctic Expedition started monitoring ozone in preparation for the International Geophysical Year (IGY) of 1957. [Corrected from 1957 to 1956, thanks to Anon in the comments for pointing me to the Dobson paper. Reference is the same as that I previously provided for the chart below. Sou. 16 Sept 14]
The hole wasn't reported in the literature until 1985. Because:
