Its has been awhile since I had a QOTW, but the last couple of weeks have been full of travel, and I’ve been out of the comment loop until recently. But this response from RyanO to the incorrigible commenter “TCO”, over at the Air Vent left me in stitches:
Negative thermometers ARE sh**. 100% sh**. I shouldn’t even need to say it to make it so. If the math results in negative thermometers, then something is wrong with the math.
Yet, we have ample evidence of negative thermometers (actual surface stations measuring air temperature where the resultant data is inverted after processing) in the Steig et al “Antarctica is Warming” paper, ( Nature, Jan 22, 2009) thanks to the careful analysis of Jeff Id and RyanO
Here’s one view of a negative thermometer:
And here’s what they look like in the Steig et al paper:

It is of course nonsensical to flip temperature data upside down when averaging but that is exactly what Steig et al does. This alone should call into question the paper’s result.
