A numerical simulation model (DEMETER) of terrestrial vegetation and ecosystems has been developed and applied to a variety of modern and paleoclimatic scenarios. DEMETER was designed to provide global scale simulations (at 1[degree] spatial resolution)of the distribution of potential vegetation types and carbon storage of vegetation, detritus and soil. The DEMETER model is forced by the results of General Circulation Model (GCM) simulations of paleoclimatic regimes. In particular, DEMETER has been used to patterns and terrestrial carbon storage associated with 6000 years before present (6 ka B.P.). Preliminary results suggest that enhanced monsoon development at 6 ka B.P. provided moisture for the extension of grasslands and savanna nearly 1000 km into North Africa, In addition, there was a [approximately]300 km northward extension of the boreal forest. These simulation results are in good agreement with available paleobotanical data.
