Anyway, I have been posting comments at his blog this week about Anthony Watts' failure to come up with the goods, and about the specific estimate of warming bias that he made to Bolt's face only last June. I don't think yesterday's comment got through on his "tips" page, although maybe I just didn't click "submit" or something.
So here is my attempt today, posted as a comment to his video post:
Andrew, you seem to be showing a distinct lack of interest in the fact that Anthony Watts' own co-authored paper has shown he was completely wrong when you interviewed him in June last year.
Are you having trouble remembering? He estimated that warming bias due to poor weather station siting in the US could account for .5 degree C of increase in the US temperature record.
You said that meant that 2/3 of the increase of .7 degree could be from this. Watts did not disagree.
His actual paper shows what 2 other studies had predicted - cooling biases had balanced warming biases and the US mean temperature record was accurate.
This is the second major, major claim on which Watts has been shown wrong - the other being that international weather station "drop out" was removing cooler stations and biasing the world temperature record.
This was quickly shown to be wrong, and not even "lukewarmenist" Lucia of Lucia's Blackboard believes it. Watts, as far as I know, has never retracted or apologised.
Andrew, why do you show no skepticism towards Watts? He made a wildly inaccurate estimate to your face, disproved by his own paper which he said was days away from being completed.
Do the right thing - get him back on the radio and ask him how specifically how he was so wrong, and to retract his earlier estimate made to you 12 months ago.
