CMIP Phase 5 (CMIP5)

In 2008 the WCRP Working Group on Coupled Modelling (WGCM), at its 12th Session, endorsed the CMIP5 protocol, which defined a set of thirty-five climate model experiments designed to be useful in 1) assessing the mechanisms responsible for model differences in poorly understood feedbacks associated with the carbon cycle and with clouds, 2) examining climate “predictability” and exploring the ability of models to predict climate on decadal time scales, and, more generally, 3) determining why similarly forced models produce a range of responses.
