Thanks to Wacki for tipping us to this  Penn and Teller edition slamming the science behind climate change - in fact, slamming science behind pretty much all environmental concerns.
For my part, I thought Penn and Teller were those guys who got mauled by their own tiger, but it turns out they aren't quite so courageous. All their work is conducted from behind the protective glass of a camera that somebody else carries into the real world.
Pushing “experts” like Patrick “Gobs of Money” Moore and Bjorn “The Skeptical Environmentalist” Lomborg, and relying even more on the cheap exploitation of ditzy environmental campaigners and on opportunistic film cuts, Penn makes fun of pretty much everybody and everything environmental. He also recruits a disinformation specialist of phenomenal ability to push an anti-dihydrogen monoxide petition (without ever offering that dihydrogen monoxide is water). It's reminiscient of every high-school gotcha pulled by a SMARMY smart kid who was trying to prove that he was a smarmy SMART kid.
Penn also dismisses the deSmogBlog's own Ross Gelbspan with an expletive - although the offensive TV host doesn't actually address any of the facts that Ross offers.
If you have the stomach to watch this tape, ask yourself if Penn and Teller were really trying to raise the level of environmental education or whether they were just tying to look clever. Ask yourself whether climate change science  is really a worldwide socialist plot or perhaps exactly the global threat that Ross so eloquently argues it to be.
Whatever answer you ultimately come to, we urge you to seek sources more serious than Penn and Teller, and experts less completely compromised than Patrick Moore, Bjorn Lomborg and the assembled industrial apologists at the Cato Institute.
