| Abstract: | Background Soil organic carbon (SOC) represents a significant pool of carbon within the biosphere. Climatic shifts in temperature and
precipitation have a major influence on the decomposition and amount of SOC stored within an ecosystem and that released into
the atmosphere. We have linked net primary production (NPP) algorithms, which include the impact of enhanced atmospheric CO2 on plant growth, to the SOCRATES terrestrial carbon model to estimate changes in SOC for the Australia continent between
the years 1990 and 2100 in response to climate changes generated by the CSIRO Mark 2 Global Circulation Model (GCM). |
