In 1969, Daniel Patrick Moynihan sent a one-page memo to a top Nixon advisor on “the carbon dioxide problem.”
“The process is a simple one. Carbon dioxide in the atmosphere has the effect of a pane of glass in a greenhouse. The CO2 content is normally in a stable cycle, but recently man has begun to introduce instability through the burning of fossil fuels. At the turn of the century several persons raised the question whether this would change the temperature of the atmosphere. Over the years the hypothesis has been refined, and more evidence has come along to support it.”
“It is now pretty clearly agreed that the CO2 content will rise 25% by 2000. This could increase the average temperature near the earth’s surface by 7 degrees Fahrenheit. This in turn could raise the level of the sea by 10 feet. Goodbye New York. Goodbye Washington, for that matter. We have no data on Seattle.” —Memo by Daniel P. Moynihan, September 17, 1969
Using the BEST temperature index from Berkely Earth, the temperature difference between 1969 and 2001 is approximately 1 degree Fahrenheit.
