In the ‘Way Back Times’ we see a jump from 1 to 4 thermometers, then back down again, and we see the dT line move with the thermometer change. A wonderful example of why, even in anomaly based processing, instrument change matters. A LOT. Period. Memorize it. Tattoo it on every “climate scientist” on Something TBD… Mr. McGuire taught me that in High School Chemistry. “Don’t screw around with the instruments while the test is running!” (A bit of a paraphrase … Mr. McGuire could be, er, “colorful”… I think we were doing a ‘heat of fusion” experiment and I wanted to check the thermometer and was reaching a “paw” towards it… thus resulting in a “few choice words” about “paws” and “science” being mutually exclusive… ;-) and something about “bright people making the worst idiots” IIRC… )
