While I am in absolutely no position to comment on this subject, I would imagine that, as with policy debates, even scientists will disagree on whether or Lomborg's work is dodgy. That, at least, is the impression I get from different groups both condemning and supporting the guy.
Anyways, the real point. I remember having seen a "book club" discussion on this book on Andrew Sullivan (yes, I know, its AS, but it is still an interesting book discussion) a long time ago.
Here is one of the relevant links (the others are currently broken, but we'll see if AS will fix them soon):
