I am unable to find any 1982 Exxon prediction that would meander like the line in that graph. The only plot I was able to find is this [1] from this 1982 Exxon report [2], which is just a slightly curved upward rising sketch, not nearly as detailed as in the xkcd graph.
> the Exxon model from 1982
I also failed to find any signs of there having been any "1982 Exxon model". What [2] is, is a 39-page report, a synthesis and review of publicly available climate research. The list of references is quite extensive: 10 pages.
Oh right, I misinterpreted the xkcd plot. It's only the single (x)-marked dot in the top right of the graph, that is the Exxon prediction. Not the graph itself.
