I think it’s almost impossible for an intelligent lay person to develop an informed opinion about AGW. Everything I see is so politicized, and usually accompanied by shrillness and hysteria.

There are really 3 separate issues: 1) Is it getting warmer? 2) If so, is man causing it? and 3) If 1 and 2 are true, what, if anything, should we do about it?

I simply don’t trust anyone on either side of the issue.
