  2. CARBON CYCLE

  3. Sink Amount in Billions of Metric Tons Atmosphere 578 (as of 1700) - 766 (as of 1999) Soil Organic Matter 1500 to 1600 Ocean 38,000 to 40,000 Marine Sediments and Sedimentary Rocks 66,000,000 to 100,000,000 Terrestrial Plants 540 to 610 Fossil Fuel Deposits 4000 Table 9r-1: Estimated major stores of carbon on the Earth.

  4. The following graph illustrates the rise in atmospheric carbon dioxide from 1744 to 1992. Note that the increase in carbon dioxide's concentration in the atmosphere has been exponential during the period examined. An extrapolation into the immediate future would suggest continued increases.

  5. OXYGEN CYCLE
