The phenology is controlled by the flux balance of carbon gains and losses, thus being dependent on the driving climate and the state of vegetation. Two equilibrium runs based on the 3xCO(2) climate were performed: (1) Considering the pure climate effect (with no direct CO2\_fertilization) we obtained a 22\% decrease of the net primary production (NPP) due to enhanced autotrophic respiration and increased water limitation. Together with the effect on the soils this results in a 170 Gt carbon source. (2) Considering a CO2-induced enhancement of the maximum photosynthesis the pure climate effect is more than compensated and we predict a NPP increase of 9\% and a total carbon sink of 50 Ct C. This effect may even be an underestimate if one takes into consideration a shift in the optimum temperature for photosynthesis under enhanced levels of atmospheric CO2\_as proposed by Long and Drake
