Newsweek‘s Jerry Adler tries to explain why all that hysteria in the ’70s about “global cooling” was not inaccurate: 

How did NEWSWEEK?or for that matter, Time magazine, which also ran a
story on the subject in the mid-1970s?get things so wrong? In fact, the
story wasn’t “wrong” in the journalistic sense of “inaccurate.” Some
scientists indeed thought the Earth might be cooling in the 1970s, and
some laymen?even one as sophisticated and well-educated as Isaac
Asimov?saw potentially dire implications for climate and food
production.

And this from the same people who can’t understand that President Bush was not lying when he quoted intelligence reports that said assertively that there were WMD in Iraq.
