I know a lot of people who have occasion, for one reason or another, to deal with climate skeptics. Sometimes this happens at public events, sometimes at Thanksgiving dinners. There are a lot of arguments that skeptics use, and it’s hard to carry around the responses to all of them in your head. I’ve just stumbled upon a website that may be helpful — though admittedly it’s awkward to pull out your iPhone or Blackberry at the dinner table or in front of a crowd and start web surfing. The site is called “How to Talk to a Climate Skeptic.” The responses are very measured and well-documented, not mean-spirited or cheap shots.
