Except that if you actually do the arithmetic, you find that the "heat trapping" properties of atmospheric CO2 concentrations can't produce the claimed temperature increases. That's why the AGW folks talk about the feedback effects, effects which are dependent on other things.
Note that the paleo record shows much higher levels of CO2 in the past (2-10x) with comparable to today temperatures....
Like any chaotic system, it is difficult to predict the outcome, just that temperature is likely to increase. Think about the Mandelbrot set.
In any case, this is where one needs to look at other evidence.
Hats off to you for refusing to poison the debate. I hope you'll read this question in the same spirit.
Have you given any thought to what evidence you'd have to see before changing your position?
It's hard to ask for evidence in advance (and probably mildly contrary to the scientific spirit :) ), but at the very least it will have to explain lots of seemingly contrary evidence (or show flaws in _all_ those studies).
update: I should also mention that I'm fairly trusting of at least some of those studies, since I know some people involved in them and they're both smart and trustworthy... Also, I'd be very surprised if CO2 was completely innocent.
There's actually a theory going around that land use may be a contributing factor to climate change along with CO2: a forest absorbs heat differently than a crop field which is different from a city. This theory demonstrates that CO2-based AGW isn't either-or.
I'm of the opinion that the AGW hypothesis is correct. I'm very confident of it. (In particular because one can derive a correlation between atmospheric CO2 and average global temperature directly from the properties of CO2.) On the other hand, I'm sure that there are many individual pieces of evidence that are false.
It's good that they're questioned and subjected to rigour. False evidence for a true hypothesis is not something we should accept.
This is how science works and it not a bug but a feature.
The political spin being put on it is a minor irritation that will go away with time.
And be thankful you don't have relatives who tell you that global warming is a government conspiracy to give power to the UN demonstrating that the Antichrist is near. That is really irritating.
