On Bloggingheads.tv, John Horgan, of the Stevens Center for Science Writings, interviews Michael Shellenberger, author of Break Through. Shellenberger advocates government involvement in climate control, and although he is a little bit too moderate on the issue for my taste, I think that he raises a good point about the inability of many environmentalists to enter the political process. For better or worse, the anti-global warming right needs to be brought around, and they hate anti-market arguments. Here's Shellenberger's website.
