The Carbon Cycle
Year:
2009
Author:
Philippe Rekacewicz assisted by Cecile Marin, Agnes Stienne, Guilio Frigieri, Riccardo Pravettoni, Laura Margueritte and Marion Lecoquierre.
Description:
Carbon stocks in forest areas comprise
carbon in living and dead organic
matter both above and below ground
including trees, the understorey, dead
wood, litter and soil. On a global scale,
vegetation and soils are estimated to
trap 2.6 gigatonnes (Gt) of carbon
annually. Yet there are still many uncertainties
about the workings of the carbon
cycle: the Intergovernmental Panel
on Climate Change (IPCC) estimates
that the amount of carbon absorbed in
the soil and vegetation amounts to anything
between 0.9 and 4.3 Gt annually.
