So what is false: the idea that we knew what was going on in 1965, and Evil Oil Companies somehow derailed this. Because that is drivel: by their own timeline, there was more than two decades between their precious report of 1965 and the disinfo. The truth, of course, is that we didn't know what was going on as early as 1965.
Note that the report-to-the-Prez in 1965 is only truthy, because they fail to note that the bits dealing with CO2 are shuffled off into an appendix; see Retread: Just 90 companies caused two-thirds of man-made global warming emissions?
