The complexity of environmental problems such as climate change means that knowledge from such diverse realms as the natural and the social sciences must be integrated.
Computer models are important tools for the integration of scientific knowledge.
There is no doubt that computer models and computer simulations are essential instruments in assessing the complex environmental dynamics that lie beyond the limits of experimental research. However, it would be seriously misleading to think of computer models as being sufficient for forming wise policy. Models are seen as a tool for organizing scientific knowledge. Focus groups will be used as a tool for organizing a social process involving scientists and non-scientists. Together, these tools will ensure that the models are not used as substitutes for democratic decision-making.
