That is not true. I was (and am) obsessed with science and the only thing I heard about then was global cooling because of carbon (as in smoke, not carbon dioxide) pollution.
The main fear back then was toxins of various kinds, from smog to nuclear to pesticides.
I agree with you that nuclear war was an earlier fear, 1960's.
Back then the concern was cleaning up the environment. CO2 was never mentioned. It was about air and water pollution, and garbage on land.
I would just like to remind everybody that nuclear war is still a major threat! It didn’t evaporate with the USSR, despite how people act. The US and Russia still have thousands of warheads ready to go at a moment’s notice. The numbers are down substantially from their peak, but the arsenals are still large enough to thoroughly wreck civilization.
I’m constantly baffled at how everyone acts like nuclear war is a historical curiosity.
This is not to take away from climate change, which is also a major threat. It’s not either-or, we should fix both.
