agreed-I guess my point regarding "a few" bad data points, is that if us weenies (and of course you Mets) notice that temp discrepancies, and they are not addressed for a long time, it's a problem like you said.
I'll not beat a dead horse on this. I just think that unless the data being used is confirmed to be accurate (regular instrument calibration, etc), it shouldn't be used to used to support the CC debate (on either side) or for climate records. for all we know, a certain percentage of the data is skewed too low, which would mean that CC is way worse than we think.
