BEST versus NOAA – Washington State – Cooling the Past Again

In our continuing adventure comparing the last data from Berkley Earth Surface Temperature project (BEST) today we are looking at Washington State.

NOAA/NCDC data suggests the last 5 years have cooled off considerably in Washington State. But even more interesting is that the 10 year period from the late 1800s to around 1907 was in fact warmer than the last 5 years.

Here is the NOAA Washington Data. The boxes are 5 year averages. Blue is below the 1951-80 average. Red text indicates warmer. As you can, the average for the last 5 years is .16C while the late 1800s early 1900s have anomalies of .44C and .47C. It ruins the AGW narrative for it to be so warm so far in the past.

Here is the same period using the BEST data. As you can see the same 1800s/1900s period is now -.2C and -.19C below the 51-80 average and much colder than the recent period.

How did they do that? BEST adjusted way down all the data before 1926 or so thereby artificially cooling the warm past. The following graph is the BEST anomaly minus the NOAA anomaly. They didn’t do much to the post 1930 data. Clearly they did not want anyone thinking it could be warm in the past.
