for each model strongly depend on the assumptions made for the likelihood, i.e. the
metric chosen to define model performance. Future model intercomparisons and
methods to quantify uncertainties will face additional challenges when combining
perturbed physics ensembles (a single model run with multiple parameters sets) and
structurally different models, and when trying to incorporate structural error, i.e. the
fact that many models tend to have common biases. Whether and how to weight
models in multi model projections seems unclear at this stage. Some recent studies
have proposed ways to do so while others have shown that the pitfalls may be larger
than the potential benefits.
