It was largely unsupported by any scientific data or conclusions, which is the point of the Web site for which I provided the link.
The current global warming trend, both causes and implications, has a much better established scientific foundation.
Yes, you're right. The attempted ice-age-scare was merely one of many attempts; the enviros getting warmed up, as it were. Their Big One in the 80s was Nuclear Freeze. They succeeding in convincing a large number of suckers around the world that the only way to stave off nuclear war was the Freeze, and here in the US, they shut down nuke-power. So they moved on from ice-age-scare to nuke-freeze and now to global warming, which is the ultimate scare-tactic because you can prove it with any set of data you want. Getting warm? That's global warming. Getting cool? That's an effect of global warming. Too much rain? Warming. Too little rain? Warming.
It's the perfect socialist ploy.
"Better established foundation"? Really?
