Galaxiom, you said this in the context of comments that water vapor was the REAL culprit in global climate change:
This is surely the most pathetic excuse put forward to justify doing nothing.
No, it isn't, but you can't see it as a suggestion to direct attention to a place where you MIGHT be able to do some good. Whereas focusing on the wrong answer is a sure way to be a loser.
Proof of the concept of focusing on the wrong thing being a disaster? WWII and Adolf Hitler's fixation that "the real invasion" would come through Pas de Calais rather than Normandy. And when the invasion came, he was quoted WEEKS AFTER THE LANDING as saying, (in German, of course) "It is a feint. They will attack through Pas de Calais."
Want another case of focusing on the wrong thing leading to bad results? How about being any one of the folks who bought in to the phlogiston theory of heat? How did that work out, eh?
Greg, I know you feel strongly about this, but I can't seem to find a way to explain it to you that your eggs are all in one basket, and it is the WRONG basket.
Is our climate changing? Yes. Is part of that change global warming with the concomitant increase in heat-exchange energy flows causing crazy weather? Yes. Is it all due to CO2? Here I have to say I think the math does not bear up to a cause-and-effect standard of proof. Water vapor is a better candidate but the question remains as to whether that would involve anthropogenic sources. CO2 levels might well be an effect rather than a cause given that water can absorb CO2 (and usually does, which is why oceanic pH isn't 7, but rather sits slightly on the acidic side of things.)
