Fossil Fuel Emissions Can Overwhelm Planet's Ability To Absorb Carbon

Summary:
If fossil fuel emissions continue to rise, the land and oceans will eventually exceed their capacity to absorb carbon dioxide from the atmosphere, according to a new, improved computer climate model developed by UC Berkeley, NCAR and Woods Hole. The model, one in the first generation to include the Earth's carbon cycle, indicates that vegetation and the oceans can only absorb so much CO2 before they top out and become less efficient at removing carbon.

The Earth's various sources and sinks for carbon. The land and oceans can absorb some of the increased carbon from fossil fuel emissions, but as the emission rate increases, these sinks saturate and become less effective at removing carbon from the atmosphere. (Graphics by Inez Fung/UC Berkeley)

BERKELEY -- One in a new generation of computer climate models that include the effects of Earth's carbon cycle indicates there are limits to the planet's ability to absorb increased emissions of carbon dioxide.
