Those stubborn, ugly facts of modern climate science, documented.
Government climate research agencies, such as NOAA/NCDC and NASA/GISS, do not publicize the fact that they adjust historical temperatures on an almost monthly basis.
They claim that their tampering with the actual historical evidence is "quality control". That's a blatant misdirection, as it is well understood by the people familiar with the situation that there is extreme pressure to report scary "global warming", so as to conform to the political agenda on climate change.
Since May 2008, the web site www.climate4you.com has been tracking the NOAA "adjustments", using two specific months as an example (see accompanying chart).
If there is zero to little global warming, then it is up to the bureaucrats to make it happen.
The most brute force way to fabricate global warming is to adjust those monthly temperatures prior to 1950 downward; then adjust the post-1950 temperatures higher. Wonder of wonders, as the chart reveals, that's exactly what the bureaucrat-scientists did - to the tune of a whopping +2.2°C per century trend rate, in this specific case, since May 2008.
Not so shabby, especially if they can keep that level of science hoaxdom up across all historical months going into the future.
And America's worthless mainstream press goes right along with this fakery, with the sole goal of keeping the U.S. taxpayer in the dark to the benefit of politicians, their favorite greeny-crony capitalists and the 'at-the-public-trough' climate agencies.
