Ok, I know I'm beyond my post limit and probably annoying everyone by now,
but let me ask my interlocutors this: have you read the recent NY Times
piece on the "middle ground" in the warming debate? I wish I could link it,
but the archive is fee based; here's a link to Volokh discussing it (
http://volokh.com/posts/1167922177.shtml). Essentially it is this sort of
perspective I'm trying to articulate.
