Sentences with phrase «trace gas emissions»
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.

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»
Table 6: Pathways of organic agriculture to directly or indirectly reduce agricultural trace gas emissions
To determine whether differences in substrate quality across permafrost regimes control trace gas emissions to the atmosphere, we used a reciprocal transplant study to experimentally evaluate environmental versus substrate controls on carbon emissions from bog, internal lawn, and permafrost peat.
«Scenario A assumes continued exponential trace gas growth, scenario B assumes a reduced linear 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.»
4.1 Trace Gases Scenario A assumes that growth rates of trace gas emissions typical of the 1970s and 1980s will continue indefinitely; the assumed annual growth averages about 1.5 % of current emissions, so the net greenhouse forcing increasese xponentially.»
A concentrated global effort to reduce CH4 and other trace gas emissions may allow the CO2 amount to be as great as 520 ppm without spelling doom for the ice sheets.
Scenario A assumes that growth rates of trace gas emissions typical of the 1970s and 1980s - will continue indefinitely; the assumed annual growth averages about 1.5 % of current emissions, so the net greenhouse forcing increases exponentially.
This is what Hansen's 1988 paper says» Scenario A assumes that growth rates of trace gas emissions typical of the 1970s and 1980s will continue indefinately....»
