In 1989, NOAA’s Tom Karl said that most global warming occurred between 1881 and 1919, and that the global climate cooled from 1921 to 1979.
He now shows the exact opposite. Cooling from 1881 to 1919, and warming from 1921 to 1979.
The global temperature record is a complete farce. They simply pick a set of data which suits their current agenda.
