Skeptical Science invited 97 climate scientists to comment on the contrarian myth that there is no scientific consensus on climate change. One comment will be published every hour for 97 hours. You can read about the effort on the AGU Blogosphere, or you can read the comments here.
This is a noteworthy effort and I hope it will convince some of the people that are on the fence about what they believe. As for the contrarians, as I keep saying, there is no amount of scientific evidence that will ever get them to change their minds. They are, quite literally, out of touch with reality. Too bad.
