I don't deny man made climate change, but this argument seems to be weak. Just because two factors go up at the same time doesn't mean one caused the other. See

I don't deny man made climate change, but this argument seems to be weak. Just because two factors go up at the same time doesn't mean one caused the other. See http://www.tylervigen.com/spurious-correlations http://www.tylervigen.com/spurious-correlations. It is necessary but not sufficient to show that greenhouse gases went up in concert with global temperatures. Not that one expects them to lay our a sweeping, thorough case for man made climate change in such an article, which would be an unfair expectation. It seems more like a showcase for the bit of javascript razzle dazzle than anything else, as other commenters pointed out, surely no one involved with this article expected it to change anyone's mind one way or the other.
