In 1974, the National Center For Atmospheric Research in Boulder, Colorado showed no net warming from 1870 to 1970, and a 0.5C cooling from 1940 to 1970.
In 1975, the National Academy of Sciences reported the same thing, and said global cooling is inevitable.
In 1989 Tom Karl, the Director of NOAA’s National Climatic Data Center, said Earth had cooled from 1921 to 1979.
In 1981, NASA reported about 0.2C warming from 1921 to 1979.
But by 1999, NASA had changed the 1921 to 1979 cooling which Tom Karl reported into almost 0.3C warming, and had erased most of the 1940 to 1970 cooling.
By 2001, NASA had increased the fake 1921 to 1979 warming to more than 0.3C, had further erased the 1940 to 1970 cooling, and showed about 0.5C warming from 1880 to 1999.
NASA now shows 0.5C warming from 1921 to 1979, have completely erased the 1940 to 1970 cooling, and show 1.1C warming from 1880 to 1999. They more than doubled 1880 to 1999 warming since their 2001 graph.
The next image overlays the 2016 NASA graph on top of Hansen’s 1981 NASA graph, at the same scale on both axes. It shows how NASA has cooled the past far outside their own blue error bars. This indicates that they do not understand their own data and are not doing science.
Summarizing : NASA has completely erased the post-1940 cooling. They turned Tom Karl’s 1921-1979 cooling into 0.5C warming, and have more than doubled 1880 to 1999 warming since their own 2001 temperature graph. Malfeasance like this in most professions would have serious consequences for the perpetrators.
The NASA temperature record is wildly unsupportable garbage. Unfortunate that clueless people like Steven Mosher and Brian Cox believe it is gospel truth.
