I was in High School at the time, so while a knucklehead, still old enough to have some grasp of what was going on even if I didn't care about it.
At home, we got National Geographic, and I had my own subscription to Scientific American. Any climate stuff was global cooling. We watched a lot of PBS stuff at home, and again, I don't remember a single "global warming" show. Everything was "ice age". I think Carl Sagan may have mentioned warming in the Cosmos series, but I recall it was focused on previous warming, and that natural climate cycles were taking us to the cold.
So there might have been some global warming papers or even popular articles or TV science shows, but I remember none of them, and school science classes talked about global cooling. Even after I got out of High School and did my one year of community college before life, both the geology and geography classes I took talked global cooling.
Oh, and lets not forget acid rain. In fact I think, at least on the PBS, acid rain was a more covered, bigger threat than global cooling. I recall it was a dying theory by the early 80s though. I don't recall it being discussed in the aforementioned college classes. It was certainly a big thing in the 70s though.
When I returned to college for real in the early-mid 90s, I was in the geospatial sciences department. When I hit grad school, global warming was more of a focus, but I recall when taking an atmospheric sciences seminar and doing radiation budget equations (which were like two pages long showing your work), the professor, from France and well known in the discipline, while being a commie, was not "all in" on global warming. She was all about the math.
By circa 2010, I would occasionally be back at the university for the job, and the remote sensing dept was all in on OMG warming and the computer models, including Michael Mann's incredibly flawed model.
