At least, that's what George Will says all the scientists used to say:
While worrying about Montana's receding glaciers, (Montana Governor Brian) Schweitzer, who is 50, should also worry about the fact that when he was 20 he was told to be worried, very worried, about global cooling:Then it was global cooling, now it's global warming...what, I wonder, will it be 30 years from now?Science magazine (Dec. 10, 1976) warned of 'extensive Northern Hemisphere glaciation.''
Science Digest (February 1973) reported that 'the world's climatologists are agreed'' that we must 'prepare for the next ice age.''
The Christian Science Monitor ('Warning: Earth's Climate is Changing Faster than Even Experts Expect,'' Aug. 27, 1974) reported that glaciers 'have begun to advance,'' 'growing seasons in England and Scandinavia are getting shorter'' and 'the North Atlantic is cooling down about as fast as an ocean can cool.''
Newsweek agreed ('The Cooling World,'' April 28, 1975) that meteorologists 'are almost unanimous'' that catastrophic famines might result from the global cooling that The New York Times (Sept. 14, 1975) said 'may mark the return to another ice age.''
The Times (May 21, 1975) also said 'a major cooling of the climate is widely considered inevitable'' now that it is 'well established'' that the Northern Hemisphere's climate 'has been getting cooler since about 1950.''
Too much moderation, I bet.
