Again, one major problem with "consensus" global climate models is that there has been no warming measured at the South Pole for 50 years.
An excerpt from Steve McIntyre is here:
As I’ve discussed elsewhere (and readers have observed), IPCC AR4 has some glossy figures showing the wonders of GCMs for 6 continents, which sounds impressive until you wonder - well, wait a minute, isn’t Antarctica a continent too? And, given the theory of “polar amplification”, it should really be the first place that one looks for confirmation that the GCMs are doing a good job. Unfortunately IPCC AR4 didn’t include Antarctica in their graphics. I’m sure that it was only because they only had 2000 or so pages available to them and there wasn’t enough space for this information.Update: A related excerpt from here:
One of my favorite topics in climate discussion is "what is normal?" We have observed climate really intensely for maybe 30 years, and with any kind of reliable measurements for no more than about a hundred years. So given that climate moves in hundred thousand and million year cycles, how can we be sure our reference point, given 30 years of observation, is really "normal." One funny aspect of this is how often the headline has been flashed over the last few weeks that Arctic ice is at an "all-time" low. Really? You mean the lowest it has been in the 6 billion year history of earth? Well, no, just the lowest since 1979 when we started measuring by [satellite]. (For those without a calculator, "since 1979" is really only 0.0000005% of "all-time.")

Steve McIntyre needs to buy some new glasses and apply a bit of common sense. The maps are projected using UTM, so Anarctica is squashed and flat rather round, but it's still there! Indeed whole sections of the report are dedicated it. Just have a look in the chapters covering Polar Regions rather than continents....
