Future President Ted Cruz recently held a Senate hearing on climate which featured the two graphs below showing the various stages of NOAA’s vandalism of the US temperature record.
The graph on the left was published by NOAA around 1999, and shows about 0.5F data tampering, which flatlined after 1990. All of the adjustments were upwards at that time.
I generated the equivalent graph for 2015, which now shows about 1.5F data tampering – three times as much as they did in 1999. All of the pre-2000 adjustments are now downwards (previously were upwards) indicating that these hacks are simply making it up as they go – and not doing any actual science.
Next graph shows the 1999 and 2015 versions overlain at the same scale, and normalized to 1910-1920. There has been massive additional tampering, and the post-1990 flatline is now a hockey stick.
Next graph is an updated version of the graph Ted Cruz showed on the right side, showing how NOAA turns an 80 year measured cooling trend, into a hockey stick of warming – by simply altering the data.
In 1989, NOAA reported no US warming trend over the previous century.
Now they show about 0.5°F warming during that same period.
The way that they created this hockey stick, is by simply making up data. When they having missing data for a station for a month, they make up fake data using a computer model and mark it with an ‘E’. Almost half of their data is now fake, which makes it possible for them to create any shaped graph they want.
The graph below shows the measured trends since 1990 vs. the trend of their fake data. As you can see, more than 100% of reported warming is due to fake data from models. Thermometers no longer play any meaningful role in USHCN temperature trends.
The next graph hints at what their models are doing. It shows the amount of data tampering vs. atmospheric CO2. NOAA is forcing temperatures to rise as CO2 increases, with almost perfect correlation.
NOAA temperature graphs have nothing to do with what is occurring on this planet, and everything to do with pushing the White House global warming agenda.
