Let me try to be more explicit: if you want to assume (or, if you prefer, conclude) that aerosols produced by the increased burning of fossil fuels after WWII had a cooling effect that essentially cancelled out the warming that would be expected as a result of the release of CO2 produced by that burning, then it's only logical to conclude that there exists a certain ratio between the warming and cooling effects produced by that same burning.
Perhaps no surplus carbon sink exists at all to absorb the emissions caused by burning of fossil fuels accumulated in the earth over millions of years.
