by Judith Curry Climatic Change has a new special issue: Managing Uncertainty Predictions of Climate Change and Impacts.

It seems to me that the issue is not so much that the IPCC AR4 chapter 9 authors have made an error in determination of the sensitivity in Fig 9.20, but rather that there is unacknowledged structural uncertainty in their methods for determining climate sensitivity (both statistical and physical / conceptual).

When a show of hands is required to address uncertainties on separate climate issues I think the integrated view remains very much in play.

It is not enough to say that O'Neill and Dellingpole misunderstand or misuse «uncertainty»; as we can see the issue around risk speaks to the very heart of the matter: not just what the «facts» of the climate are, but how those facts are produced, the institutions that produce them are privileged in the political sphere and the historical context of that ascendency, and how public institutions and the public relate.

In light of all this, we have at least to consider the possibility that the scientific establishment behind the global warming issue has been drawn into the trap of seriously overstating the climate problem — or, what is much the same thing, of seriously understating the uncertainties associated with the climate problem.
