Daniel Patrick Moynihan (1927-2003) was a Harvard Sociology professor, UN Ambassador, US Senator (D-NY), as well as advisor to US Presidents from JFK to Ford. As a Democrat working in the Nixon White House, he wrote a memo on September 17, 1969, declaring that Global Warming would cause disaster by the year 2000 (the full text (PDF) is available from the Nixon Library):
Carbon dioxide in the atmosphere has the effect of a pane of glass in a greenhouse. The C02 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 C02 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. [Emph. added]While CO2 levels did increase from 1970 to 2000, there has been nothing like a 7 deg. temperature increase, the rise of sea level has not changed from its historical trend, and NY and DC are not underwater. The only thing that is under water is the credibility of predictions made by global warmists.
