Now let’s consider what happens to all that CO2 that is emitted into the
atmosphere.
Of the 6 gigatons of carbon being put into the atmosphere every year by fossil
fuel burning and the 1.5 gigatons being put there by deforestation (total 7.5 gigatons), only about 3
gigatons actually remains there.
The amount remaining can be calculated directly from the increase in atmospheric CO2.
So where is all the excess CO2 going?
