David Archer coauthored analysis of the long atmospheric persistence of fossil-fuel carbon dioxide. Ocean uptake, carbonate compensation, and weathering act on different timescales.
The response to an added carbon pulse therefore cannot generally be represented by one exponential lifetime. Rapid exchange into the ocean is also different from permanent removal into a geological reservoir.[ref]
