Czech Republic president Vaclav Klaus, in an interview with the Czech economics daily Hospodárské noviny ("Earwig transfer"), on global warming:
Q: Isn't there enough empirical evidence and facts we can see with our eyes that imply that Man is demolishing the planet and himself?
A: It's such a nonsense that I have probably not heard a bigger nonsense yet.
Q: Don't you believe we are ruining our planet?
A: I will pretend that I haven't heard you.
At the bottom of the piece it says, "[English translation from Harvard Professor Lubos Motl]."
(via commenter Murph at Tim Blair's, who calls him, as many, many others have, "Vaclav Havel." The way you keep 'em straight is, Klaus is the Czech president who wasn't into the Exploding Plastic Inevitable.)
Update: Not being a journalist, I didn't include Vaclav's next line, the one that supposedly made the interview newsworthy: "Perhaps only Mr Al Gore may be saying something along these lines: a sane person can't."
