In 1961, there was a unanimous consensus for global cooling
The 1975 National Academy of Sciences report showed this cooling.
NCAR showed this cooling
NOAA showed this cooling in both Radiosonde and surface data
Hadley still shows this cooling in their radiosonde data
But NASA GISS shows no cooling during the 1960s
Surface and radiosonde data from multiple sources showed similar strong cooling, but NASA shows a slight warming during that period
The next graph shows the hockey stick of divergence between GISS and the legitimate data sources.
The global cooling scare doesn’t fit the NASA agenda, so they simply got rid of it, the old fashioned Orwellian way.
