It's easy to find tons of similar articles just by typing "myth global cooling" into Google. The problem is, they are all modern articles. It is easy to cherry pick articles from the 70's to demonstrate a a lack of consensus - just as it will be easy to do the same 50 years from now to show that there was not a consensus regarding global warming - even though there obviously is. The CIA article I referenced previously was written during the time period. It was a serious attempt to assess the seriousness of the threats perceived at the time. It was not an unfettered endorsement of "global cooling", but instead encouraged more research to see if the cooling was real and a danger to agriculture. "Warming" may have been discussed in a few seminal articles at the time, but it was far enough out of the mainstream to not even be mentioned in the CIA assessment.
I started my PhD work on atmospheric physics in '77. There is no question that the consensus was strong when I started. To question the concept was to be labeled a heretic - although not as vigorously as skeptics are nowadays.

... of course, I could be wrong.

Anyone can write a Wikipedia article. A better source would be an actual assessment from that time period complete with references:

Pages 12,13, 14, etc. are illuminating.

That article might seem a little embarrassing if someone were to, say, promote it as reflecting some kind of scientific consensus at the time. But nobody around here would be that dishonest.
