In accordance with William Henry's well-known gas law (1803), 98% of man-made CO2 emissions are offset by an equivalent reduction in natural emissions. The return of ALL fossil-fuel carbon to its origins, by consuming all coal, oil, and gas deposits, would result in a CO2 increase of less than 10%. The oceans are a very effective sink. We can never hope to recreate the ancient, fertile atmospheres unless we release the more than 99.9% of the biological carbon that has been locked in carbonate rocks by natural sequestration. Carbon sequestration is inimical to sustaining a green planet. As a result of natural sequestration, we now live in a CO2-impoverished atmosphere.
