eating crow … all US NCDC weather data is proved a crock

Crow is on the menu at WUWT when they found out that Steven Goddard, with some help from Paul Homewood, was right about weather station data fiddling. Temperatures adjusted upward, closed stations with made up data, poor siting, the list goes on. Then governments spent billions to stop a non-existing warming as a result. Make sure you read the whole thing at this link:

And there is yet another issue: The recent change of something called “climate divisions” to calculate the national and state temperatures.

Certified Consulting Meteorologist and Fellow of the AMS Joe D’Aleo writes in with this:

I had downloaded the Maine annual temperature plot from NCDC Climate at a Glance in 2013 for a talk. There was no statistically significant trend since 1895. Note the spike in 1913 following super blocking from Novarupta in Alaska (similar to the high latitude volcanoes in late 2000s which helped with the blocking and maritime influence that spiked 2010 as snow was gone by March with a steady northeast maritime Atlantic flow). 1913 was close to 46F. and the long term mean just over 41F.

Seemingly in a panic change late this frigid winter to NCDC, big changes occurred. I wanted to update the Maine plot for another talk and got this from NCDC CAAG.

Note that 1913 was cooled nearly 5 degrees F and does not stand out. There is a warming of at least 3 degrees F since 1895 (they list 0.23/decade) and the new mean is close to 40F.

Does anybody know what the REAL temperature of Maine is/was/is supposed to be? I sure as hell don’t. I don’t think NCDC really does either.

In closing…

Besides moving toward a more accurate temperature record, the best thing about all this hoopla over the USHCN data set is the Polifact story where we have all these experts lined up (including me as the token skeptic) that stated without a doubt that Goddard was wrong and rated the claim “pants of fire”.

They’ll all be eating some crow, as will I, but now that I have Gavin for dinner company, I don’t really mind at all.

When the scientific method is at work, eventually, everybody eats crow. The trick is to be able to eat it and tell people that you are honestly enjoying it, because crow is so popular, it is on the science menu daily.

Paul’s work show exactly why you have to use untarnished absolute temperatures rather than anomalies, infilling and gridding for this type of analysis.
