Abstract
Various approaches on the integration of models of climate and society have been undertaken over the past years and decades. This has either been done creating models from scratch, thus creating all the relevant submodels specifically for this integrated model, or by combining existing models for the various fields to be integrated into one model, thus usually involving a significant decrease in complexity from the specific model to the submodel within the integrated model. The approach from scratch has the advantage of high intra-model compatibility and clarity in design whereas it may lack proficiency in some parts due to the reduced knowledge-base of only a few modelers. The combination approach on the other hand delivers a platform that brings together high quality models from various fields, thus combining a large knowledge base, but creates technological and methodological problems in combining all submodels to one, highly interconnected model. We give a comprehensive overview of current attempts to integrated climate and society models and point out the advantages and disadvantages of each model.
