IPCC has placed high priority on communicating uncertainty

JC comment:  To me, the emails argue that there is insufficient traceability of the CMIP model simulations for the the IPCC authors to conduct a confident attribution assessment and at least some of the CMIP3 20th century simulations are not suitable for attribution studies.   The Uncertainty Monster rests its case (thank you, hacker/whistleblower).
