Scenario C is a more drastic curtailment of emissions of chlorfluorocarbon (CFC) emissions by 2000 and reduction of CO2 and other trace gas emissions to a level such that the annual growth rates are zero (ie., the sources balance the sinks) by year 2000. (climateaudit.org)
It said «Scenario A assumes continued exponential trace gas growth, scenario B assumes a reduced linear linear (sic) growth of trace gases, and scenario C assumes a rapid curtailment of trace gas emissions such that the net climate forcing ceases to increase after the year 2000» (realclimate.org)
