I've heard "they used to think we were headed into another ice age!" a global warming denial talking point a few time and it's really fascinating to read historical reporting on the issue.
A key point shown here is that they say they didn't know why the cooling was happening.
It was the soot from pollution, what we today call PM25 that was going to blot out the sun.
The same effect that would cause a nuclear winter as the detonations blasted tons of soil into the stratosphere which would take centuries to fall to earth. Crops would fail from lack of sunlight and lead to mass starvation. It's featured in the British dystopia movie Threads. Global Cooling in response to Global Warming is a key point of why Al Gore rebranded it to climate change.
That's very plausible to me I've just never seen the topic discussed with the modern scientific knowledge. Was the cause discovered relatively quickly, and that's why it stopped being reported on? Or was it just counteracted by CO2 driven warming?
I don't remember, it just kind of dropped out of the conversation because it never happened the way they said it was going to. I'd advise looking up the nuclear winter concept if you want to know more. Or just watch Threads, it's terrifying. If you really want to go down a rabbit hole look up 10,000 years ago during the previous Ice Age and wolly mammoths. I got into super prehistory of hominids and it's fascinating, Gobekli Tepe and such. There was also increased CO2 then too which caused the Sahara Desert to bloom. There were rivers and forests. That's why they haven't found much more evidence of early hominids, they aren't digging in the right place. Egypt is great, there are 5 star hotels and everything. Dig in the desert, with all that sand and live in a hot tent? Decline.
