Robustness of the thermometer record

This is an interesting post up at The Blackboard: it turns out that taking random 10% samples of the weather stations and computing global means gives you a very consistent picture (also, check out Steven Mosher's comment).  This seems to align with Anthony Watts' Surfacestations project, which found that (somewhat to my surprise, at least) the poor siting of the majority of US weather stations doesn't actually affect the numbers very much.

These are both instances of good, basic fact checking carried out and reported honestly by eeevil sceptics.
