I was reading "The 1970s Global Cooling Consensus was not a Myth" at https://wattsupwiththat.com/2018/11/19/the-1970s-global-cooling-consensus-was-not-a-myth/
And so I decided to make a quick graph in R showing the extent of this consensus. Here, -1 depicts a peer-reviewed scientific article predicting global cooling, 0 is a neutral article, and 1 predicts global warming. (Dots are spread out a bit with the jitter command.) Conclusion: While far from unanimous, the majority position in the early to mid 1970s appears to be that global cooling is the likelier trend.
