I looked for a reasonably scientific explanation of the GHE on Google and was very disappointed. You would think it would be everywhere but it isnt. I then specifically searched for the IPCC version. Imagine my surprise when 'denier' sites were the major places of discussion. How weak is their case if they are effectively hiding it? For the record, I believe in the GHE in principle as a very important part of atmospheric radiative physics. I don't see how the addition of more CO2 can cause huge changes though. What is your reference site for the GHE? Or do you just know it? I'll post up a few links later if no one cares to post theirs.
