Char is trying very, very hard to be obtuse. This often happens when Char's point cannot be made.

Yes Char, in major percentages it seems CO2 may indeed be a greenhouse gas. Now, as I told you earlier, point to the empirical evidence (opinions and correlations are not acceptable) demonstrating the tiny amount that has increased in our atmosphere has caused, not resulted from, the roughly one degree of warming that has come about in the last century.

Now quit repeating yourself and trying to evade the real issue.
President Reagan summed it up nicely, "Some people go through their entire lives wondering if they made a difference, Marines don't have that problem!!!"
