I am uncomfortable with historical meteorological revision. There is enough problem with climate change non-believers that retroactive "adjustment" of historical weather records is only going to fuel conspiracy theories - especially when they are adjusted down. There is more than enough evidence of climate change without revising past records - so why do it? Especially given that this record requires that an un-identified person may have possibly made an error reading a thermometer. The evidence that this value is wrong is lacking.
