Regarding his first point, you might want to look at this, which shows worldwide snow-cover anomalies over the past 40 years trending toward less and less of it, and this, which shows global temperature trends over the past 150 or so years. A single winter or even five of them does not a pattern make.

As to his second point, Booker’s list of “climate experts” who signed the Manhattan declaration includes precious few people who could be considered eminent climate scientists. Of the 619 authors of the IPCC AR4 WG1, zero signed the Manhattan declaration. (I know, I know, every single researcher affiliated with the world’s foremost provider of up-to-date findings in the area of climate science is part of a grand conspiracy. In your world, anyway.)

And concerning Booker’s third point, he is saying nothing except that reducing emissions is unrealistic. What does that have to do with whether these emissions are contributing to AGW? (Answer: nothing, of course.)

Booker is a fraud. While legitimate debate over human industry’s role in climate change certainly exists, this clown has no credible role in it.

Like methane – a more potent greenhouse gas than CO2 – and its being “ignored” by the CO2 screamers. It’s not as glamorous, after all. Now they’ve gotten their hands on it, and global warming (now climate change) is STILL our fault because we eat too much meat.
