The Carbon Dioxide Cycle: Reservoir Models to Depict the Exchange of Atmospheric Carbon Dioxide with the Oceans and Land Plants

  • Charles D. Keeling


The following survey of carbon dioxide in nature places major emphasis on describing how the injection of CO2 into the atmosphere by man’s industrial activity has perturbed the natural carbon cycle on a global scale. In a sense, this injection is a mammoth geochemical experiment. It permits us to observe the transient response of the air, the oceans, and the biosphere to a major disturbance taking place over the interval of only a few years. Our quantitative understanding of the carbon cycle is thus repeatedly challenged and refined.
