A short primer: the Green House effect (Anthony Watts)

“So the debate is not about the greenhouse effect, it is about the feedbacks.
Suppose that the amount of reflected SW from clouds increases from 20% to 21%?  That would cause a significant cooling effect.  Thus the ability of GCM models to model future temperatures is largely dependent on the ability to model future clouds.  Cloud modeling is acknowledged to be currently one of the weakest links in the GCMs.  Given the sensitivity to clouds, it is perhaps surprising that some high profile climate scientists are willing to claim that 6C+ temperature rises are established science.

So the bottom line is that the greenhouse effect is real.  Increasing CO2 will increase temperatures.  If you want to make a knowledgeable argument, learn about the feedbacks.  That is where the disagreement lies.”
