...because of the long residence time for carbon dioxide, stabilization of emissions at current levels leads to a nearly constant rate of increase in atmospheric concentrations for at least two centuries with the concentration reaching 480-540 ppmv by 2l00, about twice pre-industrial (Figure l), and l20-l80...
