"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."

What happened and why, if we assume we are warming now, did the trend change if it even is a change?
