Slide 9 in this series.
Data adjustments by NOAA that have drawn some attention. This appears on the surface not to be some random error correction, but rather data tampering. No one can be sure, except ClimateGate can give us an indication along with the hockey stick as to how far the AGW group will go to make the data fit the narrative of AGW.
The hockey stick of adjustments since 1970 are due almost entirely to NOAA fabricating missing station data. In 2016, more than 42% of their monthly station data was missing, so they simply made it up. This is easy to identify because they mark fabricated temperatures with an “E” in their database. The missing data values when plotted against CO2 values, form an almost perfect correlation (R2 = 0.98!!! Too good to be true.). They must have been calculated to fit the AGW scenario.
NEXT: UAH vs RSS also tells us how the data correction process finally caught up with the RSS group. UAH is not under the control of the AGW groups.
A full range of topics on how global temperature works, is reported, adjusted, and some insignts into its accuracy.
