Extremal climatic states simulated by a 2-dimensional model. Part II: Different climatic scenarios

Different climatic simulations have been obtained by using a 2-Dim horizontal energy balance model (EBM), which has been constrained to satisfy several extremal principles on dissipation and convection. Moreover, 2 different versions of the model with fixed and variable cloud-cover have been used. The assumption of an extremal type of behaviour for the climatic system can acquire additional support depending on the similarities found with measured data for past conditions as well as with usual projections for possible future scenarios.
