Your reply says it all. At this point you would have been giving me your credentials as a climate scientist but what we get is 'intelligent'. I think it's a tactic one uses to close a conversation with "I'm a lot smarter than you". This wouldn't be the first time I've seen it's use. The other give away is that someone with that level of expertise in numerous disciplines wouldn't be spending their day, all day, online writing comments to newspaper columns. Sad, in a way.
