William Nordhaus was awarded the Nobel Prize in Economic Sciences because of his decades' effort to integrate climate sciences into economic models. His Dynamic Integrated Climate and Economy (DICE) is used to explain how Greenhouse Gases emissions if not tamed could lead to catastrophes down the road. This pioneering effort is not immune to criticism. Using climate-economy integrated models to design and implement specific climate policies is subject to misuses, as Robert Pindyck contended. According to Pindyck, modeler's limited knowledge about climate sensitivity and arbitrary selection of functional forms and parameter values do not make results from complicated models more valid than modeler's own "expert" opinion.
