Understanding our global environment and our role in it is the first step toward living in better harmony with nature. Reports to the Nation: Our Changing Planet Global Carbon Cycle OGP's Global Carbon Cycle (GCC) program seeks to improve our ability to predict the fate of anthropogenic carbon dioxide (CO2) and future atmospheric CO2 concentrations using a combination of atmospheric and ...

The Carbon Cycle, Climate, And The Long-Term Effects Of Fossil Fuel Burning By James F. Kasting Much has been said and written about the probable effects of human activities on the Earth's climate. Without question, the concentrations of carbon dioxide and the other greenhouse gases that act to keep the planet warm--and therefore habitable--are increasing very rapidly, and governments around the ...

USGS Carbon Cycle Research The U.S. Carbon Cycle Science Program (CCSP) is an interagency partnership that draws on the expertise and ongoing research in seven agencies, with the objective of developing a whole-system predictive capability for the global carbon system. The ultimate goal is to provide integrated estimates of carbon sources and sinks, with a focus in FY 2000 on implementing ...

Carbon Cycle The movement of carbon, in its many forms, between the biosphere, atmosphere, oceans, and geosphere is described by the carbon cycle, illustrated in the adjacent diagram. The carbon cycle is one of the biogeochemical cycles. In the cycle there are various sinks, or stores, of carbon (represented by the boxes) and processes by which the various sinks exchange carbon (the arrows). We ...

OCMIP Ocean Carbon-Cycle Model Intercomparison Project Introduction In the decade that has elapsed since 3-D ocean models were first employed to study the ocean's carbon cycle, computer technology has advanced remarkably. During that same time, more scientists have begun to employ 3-D models in efforts to improve man's understanding of ocean circulation. Others have likewise joined in, taking ...
