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 horizont al energy balance model (EBM), which has been constrained to satisfy severa l extremal principles on dissipation and convection. Moreover. 2 different versions of the model with fixed and variable cloud-cover have been used. T he assumption of an extremal type of behaviour for the climatic system can acquire additional support depending on the similarities found with measure d data for past conditions as well as with usual projections for possible f uture scenarios.
