Description
Summary:One of the most heralded options for reducing emissions of greenhouse gases is carbon dioxide capture and marine disposal. A systems approach is used to assess the relative effectiveness of this option. Parameterized models are constructed to consider the behavior of two systems: one that describes the fate of CO sub(2) emitted into the atmosphere or deposited in the ocean; and a second that considers an engineered system for capture and disposal of CO sub(2). The simulations consider a well-mixed global atmosphere and a three-dimensional ocean with complex circulation and mixing. The analysis indicates that emission control ultimately results in higher atmospheric CO sub(2) concentrations, since more CO sub( 2) is produced to fuel the capture phase. The period of time before increased atmospheric CO sub(2) concentrations are seen depends on the depth of ocean disposal and on efficiency factors of the engineered system.
