"Was an imminent Ice Age predicted in the '70's? No"
LOL, exactly my thought. Since my memory goes that far I've always been baffled by the claim.
So, what I actually remember from my college years (80's) is a warming prediction.
The only cooling prediction was a cooling from dimming, then estimated to be most probable from nuclear war, or in second case a meteor/volcanic activity. (can be one following the other)
