Most fossil-fuel CO 2 released to the atmosphere will eventually be absorbed by the ocean 1 with potentially adverse consequences for marine biota 2–4. We quantify pH changes that may result from continued release of fossil-fuel CO 2 to the atmosphere, and compare these with pH changes inferred from geological and historical records. We conclude that(More)
[1] We present ocean chemistry calculations based on ocean general circulation model simulations of atmospheric CO 2 emission, stabilization of atmospheric CO 2 content, and stabilization of atmospheric CO 2 achieved in total or in part by injection of CO 2 to the deep ocean interior. Our goal is to provide first-order results from various CO 2 pathways,(More)
[1] We simulate direct injection of CO 2 and uptake of CFC-11 in a global, three-dimensional ocean general circulation model using two model resolutions: a coarse resolution of 4° in longitude by 2° in latitude and a finer resolution of 1° in both longitude and latitude. We assess the impact of resolution on the relative effectiveness of ocean carbon(More)
A coupled climate and carbon (CO 2) cycle model is used to investigate the global climate and carbon cycle changes out to the year 2300 that would occur if CO 2 emissions from all the currently estimated fossil fuel resources were released to the atmosphere. By the year 2300, the global climate warms by about 8 K and atmospheric CO 2 reaches 1423 ppmv. The(More)
Direct injection of CO 2 into the ocean is a potentially effective carbon sequestration strategy. Therefore, we want to understand the effectiveness of oceanic injection and develop the appropriate analytic framework to allow us to compare the effectiveness of this strategy with other carbon management options. Here, after a brief review of direct oceanic(More)
