Half of NASA temperature fraud is manufactured by cooling the past. In 1981, Hansen showed a little over 0.3C surface warming from 1880 to 1980
Now they show almost a full degree warming from 1880 to 1980.
Gavin’s team accomplished this spectacular fraud by cooling the past. The graph below overlays the two images above, normalized to the five year mean of the most recent common years.
The other half of their fraud is accomplished by warming recent years, which I will cover in a later post. Make no mistake about it, NASA and NOAA are engaged in the biggest fraud in science history.
