Texas temperatures have been declining over the past century
But NOAA massively tampers with the data to make it look like Texas is warming
Much of their justification is theoretically based on Time of Observation Bias (TOBS) adjustments, claiming that people during the 1930’s reset their thermometers during the afternoon, causing double counting of hot days.
That theory is easy to test out. The graph below uses only those stations which reset their thermometers at night or morning during July 1936. As you can see, it is almost identical to the top graph for all Texas stations. TOBS has almost no effect on Texas temperatures.
TOBS adjustments are just one more excuse to tamper with data.
