a degree in the Northern Hemisphere between 1945 and 1968. Pack ice was increasing.
Glaciers were advancing. Growing seasons had shortened by two weeks in only a few
years.
In 1975, Newsweek noted “ominous signs that weather patterns have begun to
change…with serious political implications for just about every nation.” Scientists were
predicting that “the resulting famines could be catastrophic.”
