In fact we reached that in 2016.
Their estimate of a 0.84C temperature rise by then was close to the actual 0.81C in 2015.
The leaked 1982 memorandum, one of several which remained corporately
confidential with limited internal distribution for decades, discusses
the same Mauna Loa Observatory CO2 readings that were started
by Keeling in 1958.
One of Table 4's next forecasts is that cumulative CO2 will reach 450ppm
in 2030 and that the temperature rise by then will be 1.25C.

No doubt someone already had it all figured out 30 years ago. Costing, projections and contingency.
