not trying to start an argument, but reading your prior post, a reader could reach the reasonable conclusion you were making that argument. (maybe you should read you prior post in the context of the post you were responding to).
The "concrete evidence" is impossible to find on either side. And you should acknowledge that.
There are smart people on both sides that can cite evidence supporting their conclusions. Neither side can prove they are right. I happen to believe that the carbon cycle calculations and the history of rapid warming (and cooling) in the past, combined with the wealth of alarmist, over-simplified panic mongering coming from global warming alarmists that happen to have an ENORMOUS financial interest in an outcome that supports their conclusion leads to a conclusion that the man-made argument is over blown and will fade into history. I'm not saying I'm definitely right. But if you say you are right, you are taking a great deal on faith and not on science.
Point is: (1) reasonable people can disagree on this (2) villifying people that take the other side of the argument is not rational and (3) it doesn't matter which side is right because there are 3 billion people in India and China building 3 coal plants a week that make the argument irrelevant.
