Come off the raw prawn SR, this is the area the scammers have been claiming it was melting, & the melt water would sink New York.

Those inland station temperatures are very doubtful, as much of the figures are guessed, not measured. Even if the data is true, it is meaningless. The temperatures at those altitudes are never going to cause ice to melt.

Interestingly the cooling area is one where many volcanic hot spots & probable actual volcano under ice volcano have been found. If it is still cooling with volcanic heat from below, it totally knocks out the global warming theory, that the poles will heat most.

The whole fraud is over fellows, the planet is about to shoot down the theory, & the sun spot shortage will make it colder again.

More is the pity, the planet would be better for a few degrees warming.

Hasbeen,

You are wrong. It has nothing to do with a cooling effect produced by local volcanoes.

Tim Flannery guessed the cause in one of his books, saying at the time that it was his educated guess that needed to be tested by scientists to see if if was correct.

Then last year it was revealed by NASA satellites that China is pouring massive amounts of CFCs into the atmosphere in complete disregard of the Montreal Protocol.

Result: Exactly what Flannery had guessed. The hole in the ozone layer over Antarctica was opening up again producing localised cold spots in its vicinity.

I would expect someone like you who is the only ever recipient of a BSc(Eng) from Sydney Uni to recognise the consequences of this but I guess you are also one on those who deny the existence of ozone depletion for the simple reason that it is the scientists who came up with it and not you.

If Antarctica is cooler as a result of the ozone hole, then it is a clear demonstration of the usefulness of geoengineering. Here we have all these global warming enthusiasts terrified that Antarctica will melt, dramatically increasing sea levels in the process, yet they vilify China for doing something that will delay that prospect.

The only problem with Tim's story is that the Ohole was the smallest on record last year.

A graph of atmospheric cfc concentrations shows a gradual decline of cfc-11, cfc-12 and cfc-113 from early 2000s, but an increase in halon-1301, used in fire extinguishers, and a dramatic increase in SF6, an anti-arching gas used in wind turbines.

So Fester reckons we should introduce CFCs into the atmosphere to open up the hole in the ozone layer.

Unfortunately what he doesn't know is that excess UV radiation will kill the oceans' phytoplankton, which produce up to 75% of our atmospheric oxygen.

The phytoplankton help keep the atmospheric oxygen levels at around 21% +/- 2%. Outside this range humans cannot survive. That's just how things happened to evolve. Killing off phytoplankton will put us below the lower limit making it one of our probable extinction events.

That's what Fester wants to happen. And I assume he has the backing of the AGW / climate change deniers.

Dear Fester,

You asked;

If there were a big warming trend, wouldn't all the bases show it? Isn't it supposed to be getting warmer much faster at the poles?

Well no, the southern ocean provides an enormous heat sink so Antarctica will not see the rises we see in Arctic regions which are bounded mostly by land.

The Davis plot you posted certainly shows a warming trend.

There are other peninsula stations showing solid warming trends;

And look at this plot from the Faraday station on the west side of the peninsula. A solid and pronounced warming trend.

Dear old Hasbeen's nefarious lot have cherry picked stations and time scales to deliver their rubbish and he has dumped it in here without checking anything. He really is a sheep.

SteeleRedux,

As a sociologist, being someone who studies people, I am forming an opinion that the AGW / CC deniers are just a bunch of decrepit old timers with one foot in the grave who think that if they are going to die then they might as well take the rest of us with them.

So their strategy is to promote anything that will bring about the destruction of humankind. So they want the world to keep burning fossil fuels and producing CFCs - anything that will bring about our demise and bring on an extinction event.

I think Soot 'Beam up me Scotty' thinks along those lines as well. Except that Soot is only in his early 50s - he just looks like he's in his late 70s.
