I read it. The guy got some very basic things wrong. For example, he claims the earth can't warm unless the sun warms, because it would make the earth radiate more, which would remove the heat. However, by that stupid logic, it's impossible for a blanket to make a person warmer, because the person would radiate more heat as he got warmer, removing the heat. Hence, that stupid logic is obviously wrong.
So, that source fails hard at elementary physics, just like all of your sources.
You'd be more convincing if, instead of just linking to conspiracy cult web pages and yelling "I WIN!", you'd actually explain your claim in your own words. So do so. Tell us, in your own words, why CO2 has a cooling effect. Now I could summarize the crackpot argument in a sentence, but you're the one who needs to do so. After all, if you don't even understand your own theory, why should we take you seriously?
