Re: So much
Don't mention the 'f' word anywhere near a climate debate..
But here's something that was prepared earlier-

The models were also out of step with records of past climate. For example, scientists used the new model from NCAR to simulate the coldest point of the most recent ice age, 20,000 years ago. Extensive paleoclimate records suggest Earth cooled nearly 6°C compared with preindustrial times, but the model, fed with low ice age CO2 levels, had temperatures plummeting by nearly twice that much, suggesting it was far too sensitive to the ups and downs of CO2. "That is clearly outside the range of what the geological data indicate," says Jessica Tierney, a paleoclimatologist at the University of Arizona and a co-author of the work, which appeared in Geophysical Research Letters. "It's totally out there."
So climate 'science', doing the impossible since err.. whenever Shell funded the motley CRU of 'Climategate' fame. But sceptics have been pointing out low CO2 sensitivity to people like Gavin Schmidt, even before Fenton Communications set up his 'RealClimate' website for him and his mates. Quite why a bunch of comp.sci Phd's would need a PR company to spin up a simple blog is anyone's guess. Mine is Fenton's links with Al Gore, and the timing around his 'Inconvenient Truths'. Of course most of the predictions in Gore's disaster movie have been falsified.
But I digress.
Whenever reality and simulation disagree, it's usually reality that's wrong. 'The science' cannot be wrong. People have spent billions on carbon trading schemes. It can't be wrong.
Or it can. To paraphrase wot Science said, to get the temperature changes shown in the historical climate model (simulated), CO2 sensitivity needs to be high. Dogma then states that the reason why CO2 levels have increases is because of Man(n). We roughly know how much CO2 and temperatures have increased in say, the last hundred years. So we also know temps have been 6C lower than our current 'record'.
So then there's a.. slight problem where less CO2 gives more warming, which is why the 'CO2 control knob' theory is basically homeopathy. But fear not, noble climate scientists are still determined to erase the past-
