My last Science Progresscolumn of the year answers the critics of John Holdren, who strike me as being pretty off base. In particular, I explain that Holdren is not some ideologue who wants to use climate policies to wreck the economy; that an ancient bet he and Paul Ehrlich made against Julian Simon (and lost) isn't some big disqualifier; that the term "denier," which Holdren has used, is no big deal, and in fact, is a time-honored part of the English language; and that despite what some say, Holdren obviously knows the difference between science and policy. Anyways, you can read the full post here. And with that I'd like to say: Happy New Years, Intersection readers--and here's to a magnificent 2009! And don't forget to go here to answer our last post with your hopes for the future and the new administration...
