I'll try with this one, but at a certain point things just become willful ignorance, as is the case with the "in the 70's it was all about the new ice age" trope. In fact, willful ignorance would summarize OP's whole post.
Edit: But maybe initial models were decent enough:
The First Climate Model Turns 50, And Predicted Global Warming Almost Perfectly

The bigger problem is people taking the upper bound of that uncertainty and concluding they were wrong because reality turned out to not be near the upper bound. Kind of like how political polls are "wrong", even when the result falls within the margin of error.
There was a travelling exhibit that visited my high school which was an analog computer - you could set your energy sources (coal, hydro, nuclear, solar) and see how long society could run before we re-entered the Dark Ages (literally - no more electric lights!). Thinking about it - the consumption side was likely a rising wave function which predicted steadily-increasing use of electricity.
This was around the time when the EPA's Energy Star program got started, and I suspect it did a lot to counter the increase in demand.
You can also look at the films of the 70's to get some of the zeitgeist of the era - "Soylent Green", "Silent Running", "No Blade of Grass", "Damnation Alley", and so on, all with the theme that the Earth no longer nourishes life.
Or is this the new denialist meme? Instead of "in the 70s they were warning us about a new ice age" it's evolved into "in the 70s they said we'd have drowned by now".
I suppose it's getting slowly closer to the actual state of science.
