I love this quote from my Massachusetts senator who is here in Copenhagen (hat tip to the WWF Climate Blog):

There isn’t a nation on the planet where the evidence of the impacts of climate change isn’t mounting. Frankly, those who look for any excuse to continue challenging the science have a fundamental responsibility which they have never fulfilled: Prove us wrong or stand down. Prove that the pollution we put in the atmosphere is not having the harmful effect we know it is. Tell us where the gases go and what they do. Pony up one single, cogent, legitimate, scholarly analysis. Prove that the ocean isn’t actually rising; prove that the ice caps aren’t melting, that deserts aren’t expanding. And prove that human beings have nothing to do with any of it. And by the way — good luck!

Ladies and Gentlemen: Here in Copenhagen, now and forever, amateur hour is over. It’s time for science fact to trump science fiction.

Amen. These tough words are totally justified, especially in light of the new extremes that climate denialism has reached lately.
