Or do you start to think that maybe hubris and intimidation are all the AGW believers have to offer?
I'll stop asking questions the believers can't answer when they start answering them.
EDIT - Aussie, simple: it's been warmer when CO2 levels were lower. And scientists don't fully understand why. That means that you can't just ASSUME causation from correlation.
And that is precisely what you're doing. You're assuming that because THIS TIME the warming very roughly correlates to the timing of the increase, by 1/10,000th of the atmosphere, of a weak heat-trapping gas, that that increase is the cause of the 20th century warming.
There's also the fact that CO2 levels have in the last 10 years continued to increase - at an increasing rate. Yet the temperatures have NOT continued to increase.
