August 1913 was likely the hottest month in Oklahoma history, but NCDC has made the inconvenient month disappear – through massive abuse of the temperature record.
They did this by warming the present, and massively cooling the past. The graph below shows the difference between their reported maximum temperatures and the actual temperatures measured by the thermometers. All years before 1998 are progressively cooled, and they knocked an impressive 3.6 degrees off of 1913. They also added 0.2 degrees on to 2011.

Oklahoma City had 22 days over 110F in August, 1913.
Had they not tampered with the data, quite a few years prior to 1960 would have been hotter than 2011, and that just wouldn’t have suited the management at the Ministry Of Truth.
In 1913 there was no agenda, so why assume the temperature readings were not accurate? Plus you didn’t have as much concrete/asphalt and heat island back then, nor did you have runways and jet exhaust. There is actually more validity to cool the present relative to the past.
Don’t they ever explain the adjustments? Is it mainly TOBS?
