How can the IPCC’s uncertainty framework be related to decision?

How can the Intergovernmental Panel for Climate Change’s (IPCC) framework for assessing and communicating uncertainty be related to decision making? One way to attack this question is by confronting the framework with recent decision models proposed mainly by economists working on the theory of decision under uncertainty. The confidence-based decision model developed in the context of this project (see here or here) emerges as best equipped, among major existing approaches, to fully utilise the information provided by the IPCC. Moroever, the connection of IPCC conclusions with decision making via such a model brings out some an apparently novel recommendations for future uncertainty reporting.
