But no... There is no correlation between Carbon Dioxide and the greenhouse effect. Not on Earth. And there certainly isn't an example of the effects of excess CO2 in an atmosphere (Venus).
The fact that plants do better in higher CO2 environments than currently exist on Earth is beside the point... Plants also do better in jungles, than arctic tundra; That doesn't mean that expanding the tropics to higher and higher latitudes is good for the species Homo Sapiens. The point is that what is while we live in a symbiotic cycle with the vegetation on our planet, shifting the balance in one direction or the other is not necessarily beneficial to our current means of sustaining life.
And really, fourth paragraph, "Climategate"? Just because conservative media (and yes, WSJ is conservative media) declares it a scandal, attaches a -gate suffix to it, and provides one sentence quotes to totally 100% prove that the actual scandalous materials say what they are made out to say, does not mean that it is a valid scientific argument. In fact, its inclusion should be an automatic flag to take the opinion with a grain of salt. But that's just my opinion....

On a more serious note, no climate science skeptic has ever been able to explain how Global Warming is more than an American political invention. Usually what I get is that Global Warming was invented by Al Gore and the Democrats as a means to siphon money from the American Taxpayer to the liberal socialist factories we call Universities.
Seriously. Some people will believe every conspiracy theory Glenn Beck and Orly Taitz will tell them, and then doubt the very scientific method that brought us things like Genetics, Antibiotics, Atomic Theory, and manned space exploration....
