In 1989, NOAA’s head of climate analysis said most global warming occurred before 1919, and the climate cooled from 1921 to 1979.
“Analysis of warming since 1881 shows most of the increase in global temperature happened before 1919 — before the more re-cent sharp rise in the amount of carbon dioxide ut the atmosphere. said Thomas Karl, of the National Oceanic and Atmospheric Administration’s National Climatic Data Center in Asheville, N.C. While global climate warmed overall since 1881, It actually cooled from 1921 to 1979, Karl said.
