In 1961, there was unanimous consensus among scientists that the Earth was getting colder.
NCAR showed half a degree F cooling after 1940.
NASA has since erased this cooling, and made 1961 the hottest year in the 1880-1972 temperature record.
In the 1970’s, National Geographic reported that Earth had cooled half a degree.
National Geographic : 1976 Nov, Page 576In 1978, NOAA showed about 0.5C cooling from 1957 to 1977. NASA now shows 1977 as the second hottest year prior to 1980
NASA used to report this cooling, but have since erased it, in order to meet their political objectives.
Another great National Geographic find. Keep it up (-:
