Nick Stokes is raising dust over at WUWT about my USHCN data.
My USHCN calculations are very simple. I average all of the USHCN monthly data per year. The average USHCN final data diverges massively from the measured (raw) temperatures.
Nick claims that the biggest part of the adjustments is TOB (Time of Observation Bias.) That is nonsense. Most of the adjustments are the magical ones they do on top of TOB.
The hockey stick in their adjustments since 2000 is due to simply making up data. Almost half of their final temperatures are now fake.
Nick wants you to believe that area weighting the data is very important. It isn’t. The USHCN stations are relatively evenly spaced by design, though my method does tend to weight populated regions more heavily than rural regions. Overall, area weighting has a minimal effect. Every good engineer understands that you don’t obscure your code with optimizations until you have established basic principles and understand what the underlying data is telling you.
Nick also claims that I am comparing two different sets of stations. This is complete BS. USHCN fabricates missing data for almost half their stations. That is an utterly unacceptable practice.
All US warming over the past century is due to USHCN adjustments.
At the same time he was attempting to denigrate you, he was touting his own analysis, which of course, used subjective weightings (which he failed to mention, but is evident in his code). He also failed to mention that his analysis closely mirrored your own. So while his verbiage was dismissing you, his own numbers were supporting you.
I noticed the exact same thing.
But I was not sure and was falling asleep.
Thank God it is Saturday!
Congratulations, Steven aka Tony, for getting the attention of the “97% Consensus Scientists“!
A Hi-Lo thermometer reads the same numbers regardless when it is read. The only effect of Time Of Day is whether a given reading represents before or after midnight. When one is averaging all readings for a year, TOD has zero effect on the average obtained, and near zero for monthly averages.
Am I wrong?
Racehorse Nick. Destroying credibility one post at a time.
