Al Gore spoke to the American Association for the Advancement of Science (AAAS) and gave an updated and truncated version of his “Inconvenient Truth” speech. I recommend taking a look at it (you can watch it over breakfast if you’re like me and don’t like to sit and watch videos on your computer… I get restless). I am so duly impressed by what a good speaker Mr. Gore is, and how he brings both passion and intelligence to what he says, only glancing occasionally at his notes on the podium. He gave a strong call in this speech for scientists to get involved in the politics of combatting global warming. It’s a half-hour well spent.
