The Carbon Cycle is the bio-geochemical cycle by which carbon is exchanged among the Earth's atmospheric, terrestrial and oceanic carbon reservoirs. The cycle is usually thought of as three major reservoirs of carbon interconnected by pathways of exchange.
These reservoirs are:
- The atmosphere.
- The terrestrial biosphere, which is usually defined to include fresh water systems and non-living organic material, such as soil carbon.
- The oceans, including dissolved inorganic carbon and living and non-living marine biota.
The U.S. Carbon Cycle Program is an organization which seeks to better understand past changes in atmospheric carbon dioxide, deliver credible predictions of future atmospheric carbon dioxide levels and strengthen our understanding of climate change and the effect carbon has on the Earth.
The National Oceanic & Atmospheric Administration contains detailed information explaining the carbon cycle, the effect carbon has on the Earth and ways we can limit the amount of carbon released in the atmosphere.
