I make the statement because they think man made CO2 is causing global warming and I wanted to point out that it is absurd because of the numbers.
I honestly don't really care what is causing it, I know we are not and that we can not stop it. To force the world economy into a tailspin, not use the abundant coal we have, and implement socialism and confiscation of wealth for this is crazy.
But knocking down the argument that a 77ppm increase is in anyway a primary cause of "Global Warming" ought to be made with well established physical facts.
Prove that CO2 isn't a problem and all the Kyoto protocol crap gets tossed in the dumpster.
