>Time magazine articles in the 1970s
We're talking network TV and the cover of the nation's most popular magazines and newspapers. A lot of people were exposed to these ideas, lets not deny that.
>It's a strange topic for WUWT
Let me guess, you're too young to know any of this stuff, but to the boomer generation they really went from "Guys new ice age coming" to "hey global warming" pretty quickly. I think you need to sympathize with them. Yes, obviously climate change/warming is happening, but dismissing how these things get into the media, climate cooling hysteria in the 70s, etc just makes you seem like some "SCIENCE CAN NEVER BE WRONG" type who disingenuously pisses on the experiences and realpolitik of the time.
The reality is that that cooling was in the popular consciousness and led by x amount of high profile scientists. It happened. The question in my mind is what stops this from happening again? Nothing as far as I can tell. Experts have a high levels of influence and combined with mass media can change or understanding of things pretty quickly. This is often a feature of our mass communication society, but it is just as likely to be a bug (wrong facts, conspiracy theories, propaganda, etc). The internet seems to make this worse.
tldr; science is as much political as it is technical
