text: The adjustments do seem to be very aggressive in identifying any effects that might have artificially created a cooling trendbut lax in finding and correcting effects that mighthave artificially created a warming trend. First and foremost, the changing urban heat island effect in growing cities seems to be under-corrected (Again there is debate on this -- the proprietors of the model believe they have fixed this with a geographic normalizing, correcting biases from nearby thermometers. I and others believe all they are doing is mathematically smearing the error over a larger geography).
