Early Global Warming Scare

Here is a bit from a post by Lubos Motl on his The Reference Frame blog. He notes that in September 1969 Daniel Patrick Moynihan sent a memo to President Richard Nixon warning about the imminent peril of "global warming".

Lubos Motl has looked at the accuracy of these predictions:

	Predicted increase	Actual increase	Overestimate by (in pct)
CO2 conc.	81 ppm	45 ppm	80%
Temperature	3.9 °C	0.3 °C	1200%
Sea level	305 cm	10 cm	2950%

Sadly, I suspect the current dire doomsday predictions of the "global warming" crowd will prove to be no more accurate than Moynihan's. The problem with being a doom-and-gloomster is that there is a psychological component that compells a person to over-indulge in pessimism.
