When I was in high school, they still thought the next ice age was coming. The first computer model of the Earth’s climate wasn’t built until 1967 because computers weren’t a thing. And it wasn’t till 1988 that climate issues hit the headlines (I was 33!). Then followed years of debate.
So climate took a back seat to the pressing issues of civil rights, polluted lakes/rivers, the imminent threat of nuclear war, holes in the ozone layer caused by CFCs, women’s rights, etc. Boomers fought hard on the issues of their day. We didn’t have the predictive capabilities that exist today.
That’s fair and nobody expects prescience. But every Boomer I know can reminisce about how there was more snow when they were kids one minute and flat out deny that global warming is happening the next.
Maybe that’s just your area. Where I live, we’re all rabid environmentalists. Reduce, reuse, recycle. Beach cleanups and anti-logging. The q whole nine yards. Of course, Boomers were born between 1946 and 1964, so we are not only huge in numbers but diverse in ages.
