Michael Mann vs Michael Mann: Did I say that the hockey stick might qualify to be the "truth" as portrayed in the IPCC Policy Makers Summary? I meant it was an "obscure graph" that unnamed other people have made "appear more definitive than it was ever intended"

...A proxy diagram of temperature change is a clear favourite for the Policy Makers summary. But the current diagram with the tree ring only data somewhat contradicts the multiproxy curve and dilutes the message rather significantly. We want the truth. Mike thinks it lies nearer his result (which seems in accord with what we know about worldwide mountain glaciers and, less clearly, suspect about solar variations). The tree ring results may still suffer from lack of multicentury time scale variance. This is probably the most important issue to resolve in Chapter 2 at present.

Flashback: Mann calls the hockey stick "an obscure graph"; other unnamed people have stripped the error bars away, "making it appear more definitive than it was ever intended"; "the entire apparatus for propelling this manufactured scandal on to the world stage was completely funded by the fossil-fuel front groups"
