Document Summary
Rocks primarily limestone and dolomite and deeply buried sediments. Dissolved carbon dioxide in deep ocean waters. Dissolved carbon dioxide in the shallow ocean waters. Dissolved organic carbon in ocean waters derived from decay of formerly living biomass. U. s. with 5 percent of global population accounts for 25 percent of carbon dioxide emissions. China expected to surpass u. s. as largest emitter of carbon dioxide. India and brazil are also posed to increase emissions. Methane-flammable hydrocarbon gas that is chief constituent of natural gas, is one of the major greenhouse gases. Hydrocarbon: organic compound made of carbon and hydrogen. Cutting or burning of forests releases carbon on much faster scale than forests can be regrown. Soils and litter on top of soils release carbon in to the atmosphere when forests are harvested or burned to clear land for agriculture. Processes that remove carbon dioxide from the atmosphere. Dissolution of carbon dioxide in ocean waters. Dissolution of carbonate sediments on the sea floor.
