In 1999, NASA’s James Hansen showed about 0.4C global warming from 1880 through the late 1990’s, for rural, small town and urban areas.
NASA now shows three times that much global warming (1.2C) from 1880 through the late 1990’s.
It is bad enough that NASA tripled 1880-1998 global warming by altering the data, but when we consider that NOAA’s Tom Karl said the planet cooled from 1921 to 1979, it becomes painfully obvious that we are dealing with the biggest scam in science history.
