Concerning the issue of the drift in the Von Storch run: they now have at least one paper plus one submitted comment where they redid their model run without the drift, they call this ECHO-G II, the version with drift is now ECHO-G I. I think this argues for leaving the ECHO-G I curve out of the graphs, and just having one sentence in the text stating this is not shown as it was found to drift, and has been superseded. It is an outlier that messes up the graph, and if it is known and even acknowledged by its authors that it is a model artifact, why show it in IPCC? Stefan
