From the article: “I think I’m on pretty firm ground when I suggest Eric Schmidt is likely to devote a lot of time and money in the future to attacking climate skeptics.”

Well, here’s a guaranteed way to attack skeptics, Mr. Schmidt: Provide proof that humans are causing the climate to change. As soon as you provide proof, skeptics will change their minds and see it your way.

That shouldn’t be too hard to do considering all the claims that have been made about CAGW. It shouldn’t take more than a few weeks to assemble an unassailable proof that connects human-caused CO2 to changes in the Earth’s climate. Just Google it.
