"Mr. Ebell, I'm sorry, but I feel like I walked in on you in bed with my wife and you just spent the last two hours asking me if I was going to believe me or my lying eyes." The crowd (and remember, this was a Federalist Society event) chortled.
"I mean, heat waves killed hundreds or thousands in Europe and Chicago. Coral reefs are dying off. Bark beetles are devastating forests they've never been found in before because the temperatures were to cold to sustain them. I don't have to go through it all, you've heard it all before... data point after data point after data point says global warming is a problem."

"Which leads me to my next point - your claim of non-partisanship. I've heard Senator Inhofe, Richard Pombo, Tom delay when he was there and many others mis-state the science, often while quoting your organization. But I'm looking at your web-page right now, and I see story after story that supposedly debunks Al Gore. Why haven't you ever had anything bad to say about a Republican? Because to a simple guy like me, well, when I look at the big picture, it looks as if you folks care less about the truth than you do about furthering a pro-business agenda."
