The Stabilization of CO2 Level in the Atmosphere 929189

Twenty strategies to stabilize atmospheric CO2 level are examined. Controlling the rate of CO2 emissions first, by modest conservation and increased use of methane, is feasible; it costs little and provides a stable base for other action. Projections of CO2 level up to the year 2100, with and without emission stabilization, make good back-drops for quantifying other controls. No method studied can control CO2 level by limiting CO2 output; failures are economic, ecological, or due to lack of effect. Assessments are tabulated; some are plotted.
Anthropogenic Peat takes a different approach: Biomass grown to remove CO2 from the air is digested to methane and organic residue; the residue is buried as AP to control CO2 level and methane becomes a renewable fuel. AP can control CO2 level at current fuel prices; as fossil fuel displacement is not required, no disruption of economies need take place. A detailed example is given.
