The process through which the atmosphere and water continuously exchange molecules of carbon dioxide. The diffusion of carbon dioxide into the oceans accounts for almost half of the carbon extracted from the atmosphere. The colder oceans absorb more CO2 than warmer waters, since such gas is more soluble at high pressures and low temperatures.
Permanence
Permanence
Time at which carbon stored by sequestration remains in a carbon pool without being rereleased. Only permanent carbon pools are acceptable for climate policy purposes.
