A clear rundown on the climate issue

So let’s come back to our original question — what is it exactly that skeptics “deny.” As we have seen, most don’t deny the greenhouse gas theory, or that the Earth has warmed some amount over the last several year. They don’t even deny that some of that warming has likely been via man-made CO2. What they deny is the catastrophe — they argue that the theory of strong climate positive feedback is flawed, and is greatly exaggerating the amount of warming we will see from man-made CO2. And, they are simultaneously denying that most or all of past warming is man-made, and arguing instead that the amount that is natural and cyclic is being under-estimated.

Warren Meyer has a nice description of the factors involved in Understanding the Global Warming Debate. It is a good place to start if you want to understand what the ‘debate’ is all about.
