Your links demonstrate the basis for a greenhouse effect, but they don't they don't do so quantitatively. In effect they establish what is widely known. Greenhouse gases have the effect of warming the planet. This is a trite question with a trite answer.
The relevant questions of the debate about what we should do is how much warming will occur due to our CO2 emissions and what can we realistically do about it.
Upon realising that all our pee ultimately goes into the oceans, do we start building sea walls to stop the flooding of our coastlines or move to higher ground or stop drinking so much in order to reduce our pee footprint? No, before we do anything so daft, we have to think hard about how much of a sea level rise we should expect from all that pee and that requires a quantitative analysis. Something the AGW camp just isn't able to give us at present.
There may be good reasons to reduce our use of CO2, economic/peak oil reasons, but the evidence on AGW does not establish it as one of them.
Finally, I note your response to JBoyer:
"Heat "dissipated" – as you put it – by evaporation returns when the water condenses and falls as rain. Higher temperatures should lead to more evaporation and more release of latent heat when the water condenses possibly driving stronger storms."
This is not correct. The point is that evaporation takes heat in at the surface and "releases it" high up in the atmosphere above a very large chunk of the greenhouse gases that otherwise trap it. It follows that evapouration is in fact a very significant mechanism by which considerable heat escapes without having to pass through the entirety of our greenhouse gases. As I have read this is mechanism is not well accounted for in the computer models because. as with clouds it is complex, chaotic and difficult to measure.
