Two veterans of the climate wars, John Fleck (a reporter) and William Connolley (a scientist) team up for RealClimate to bring perspective — and data — to the endlessly misleading "How can we believe climate scientists about global warming today when back in the 1970s they told us an ice age was imminent?"
"Between 1965 and 1979 we found:
- 7 articles predicting cooling
- 44 predicting warming
- 20 that were neutral
In other words, during the 1970s, when some would have you believe
scientists were predicting a coming ice age, they were doing no such
thing. The dominant view, even then, was that increasing levels of
greenhouse gases were likely to dominate any changes we might see in
climate on human time scales."
They even include a nice graph. For more, see the story in USA Today.
