I imagine the question is less straightforward since the ocean absorbs something like 2/3 of the CO2.
...just found this too, though I don't know what the 44/12 rule is. Ocean absorption I mentioned?

We've come from an atmospheric concentration of 280ppmv and 58F,to 411ppmv and 59.4F as of 2015.
I don't have any data on the ocean carbon budget with me.
The ocean does have a 100-year delay time as far as warming goes,so there's more heat in the 'pipeline.'
Also,due the the 'parasol effect' effect of atmospheric sulfate aerosols,there's some immediate additional warming as soon as we turn off the coal-fired power plants.
We don't need to calculate anything really,we have direct ,measurements,plus the paleo record going back over 4-major Ice Ages.
