The aim is to find the optimal value of a global welfare function with maximum production at least costs from climate change and unemployment. Up to now the model is only used on a global scale and the costfunction is only using the predicted temperature. Sensitivity tests of the model are currently carried out. These models can be used for scales of about 100m to 10 km. The integration length is in the order of a few days.
Special interest is put on chemical spezies.
North-atlantic cyclones have been studied. The model is especially useful if really local informations are needed. In all models this is or will be improved in the near future. Currently the matching of the global scale of the economic model and the regional scale of the climate models is rather weak. Some intermediate regional economic modelling could lessen this problem.
