It has now been independently confirmed, by multiple persons, that my results regarding the impact of station dropout on global temperature are correct. Your claims, in your document with Joe D’Aleo for the SPPI, are just plain wrong. …
If you have any honor at all, you’ll set the record straight. You owe it to everyone, and especially to NOAA, to admit that you were wrong. And you certainly owe it to NOAA to apologize. You need to make a highly visible, highly public admission of error, and apology, for using falsehoods to accuse others of fraud.
My post from way back in 2004 on station dropout may be of interest.
