The Frankfurt Biosphere Model (FBM), a mechanistic, seasonal and prognostic compartment model of the terrestrial biosphere, has been developed in recent years to simulate the carbon exchange fluxes between the vegetation and the atmosphere with a spatial resolution of 0.5{degree} x 0.5{degree} on a global scale. In this contribution the authors use the FBM to assess the possible changes in the transient response of the northern forest biomes under a future 2 {times} CO{sub 2} climate. The development of these ecosystems from its initial seedling state to its climax state is simulated under different climatic conditions. In their simulations the 2 {times} CO{sub 2} climate provided by the GCM of the MPI fuer Meteorologie in Hamburg (ECHAM) is used. The differences in vegetation`s growth under contemporary and future climate can be assessed by performing two model runs with the same parameterization but with different driving climatic variables for each vegetation type and location.
