He's got a lot of really bad arguments. His "Modern Human-Extinction Scares" slide is an ad-hominem at best. The very next slide is a blatant appeal to authority (in himself). And the very slide after that basically says "Scientists are stupid and get to be wrong a lot". And then he goes into the "CO2 is good for plants, so nothing we do with it could possibly be bad" gripe.
And the "this chart is intended to Inform, not Scare"? I've seen less biased charts from James Inhofe. And apparently, the decrease in deaths from lightning in the US is proof global warming isn't causing an increase in disastrous weather.
I expected more from someone of his background. With opponents this stupid, it's no wonder climate change is generally accepted. I'm generally inclined to agree with the general premise that while the earth is warming, there's no strong evidence it is doing so catastrophically as a result of human interventions. But I'm ashamed to say such a thing in the face of such a dreadful slide deck.
