In 2017 Tony Heller broke the story of how NOAA and NASA have been routinely adjusting their historic global temperature records to cool the past and warm the present in order to create the illusion that the climate is warming, far more than it is.
The post by Heller at the link above focuses in on how that tampering, which erased from the temperature data the record-hot year of 1934, is then used by both NOAA and NASA to claim each year for the past decade was the hottest ever.
The raw data however tells a far different story. The raw data from 1934, as reported amply at the time, recorded big heat waves and murderous droughts and extensive dust storms, all far more extreme than anything we have experienced in the past decade. Moreover, that raw data matches well with public news stories, and also matches well with all the published science prior to the 2000s.
Since then, however, intellectual honesty and the real scientific method has been replaced by an agenda-driven political manipulations. Having 1934 be the hottest year ever cannot stand, especially if present temperatures do not exceed that year’s records. Global warming demands a correction!
The nicest interpretation we can give to these adjustments is that the scientists are innocently engaged in confirmation bias. They believe the Earth is warming due to increased carbon dioxide in the atmosphere, and thus they must find evidence of that warming, even if it requires data adjustments to past record-hot years like 1934, adjustments that they then rationalize as necessary and scientifically justified.
More likely, they have decided that their political agenda to prove human-caused global warming requires them to be intellectually dishonest and the falsify the global temperature record. If so, this is a tragedy beyond words, as it signals that the revolution in human thought that began with the Renaissance and Galileo and was reinforced and cemented by the Enlightenment and Francis Bacon, has now ended.
That revolution made possible a burst of human creativity and civilization that lasted more than five hundred years. The consequences for future generations should that revolution be rejected now cannot be good.
