For those of you who might want to drill down to micro-level data in the same vein as Cam's post above, you might want to have a look at the posts on
http://www.climateaudit.org/ for February 22nd thru 24th. It's a tough slog at times to wade through what McIntyre is saying, but it appears to me that he's on to something. If the base data for temperature measurement at invidivual stations is wrong (or has been fudged) or at the very least is suspect and perhaps subject to error -- maybe we ought to have a second look at what's going on before we follow Algore down the path of reinventing the world economy.
And, while we're at it....has anyone on the PC side of this issue explained why the ice caps on Mars are disappearing? Might it have somehting to do with the sun? (They don't call it the 'solar' system for nothing).
