No, that is a meme promulgated through the claim that the climatologists can make statements of accuracy to within .04 of a degree, when the thermocouples and thermometers they use are only capable of accuracy to within .1 of a degree C. In other words, their claims are preposterous.
Standard error - Wikipedia

SEM is usually estimated by the sample estimate of the population
standard deviation (
sample standard deviation) divided by the square root of the sample size (assuming statistical independence of the values in the sample):
where
s is the
sample standard deviation (i.e., the sample-based estimate of the standard deviation of the population), and
n is the size (number of observations) of the sample.

Westwall would fail Statistics 101. All the deniers here would fail it. I've tried to educate them on this topic. It's not possible. The topic isn't that difficult, but it's like trying to teach poo-flinging monkeys.
That's the heart of the issue. The deniers here believe they're brilliant, but they're actually not very smart. And they're not smart enough to understand that they're not smart. Dunning-Kruger Syndrome.
Since they can't understand they're not smart, they assume that they are smart, and that their stupid denier claims aren't really stupid, and that people who disagree with their stupid denier claims must all be engaged in a conspiracy.
Nope, no conspiracy. Deniers are just dumb.
