It is worth noting that comparison of the results of simulation runs from multiple models that use the same or similar inputs is a frequently used technique of energy and climate modelers.
- Stanford Energy Modeling Forum and Kyoto
In the late 1990s, Stanford’s Energy Modeling Forum sponsored an effort in which thirteen teams that had built integrated assessment models (IAMs) ran simulations examining the anticipated results of implementation of the Kyoto Protocol. See John P. Weyant and Jennifer N. Hill, Introduction and Overview, Energy Journal, Special Issue, 1999, vii-xliv.
- IPCC assessment reports
These rely heavily on simulation runs of multiple general circulation models (GCMs) in which the same/similar assumptions are used. For example, see Climate Change 2007-The Physical Science Basis, Contribution of Working Group I to the Fourth Assessment Report of the IPCC, Chapter 8, Climate Models and their Evaluation, pp. 589-662.
In a sense, this is a different form of sensitivity testing where the results are tested, not just for sensitivity to specific parameter values, but for sensitivity to the underlying model structure.
