I think it is more than pixie dust though. There is a community of people who study correlations and statistics who consistently attribute more climate variation to solar forcing than it makes sense to come out of the direct models. (Where "more" is the difference between saying solar forcing is 20% of recent change or solar forcing is 30% of recent change, etc. A noticable but not dominant effect). This leaves open an expectation that there may be some meaningful indirect effect of solar variation on climate. At the same time there are a couple plausible seeming mechanisms (cosmic ray ionization, UV heating of the stratosphere, etc), that could provide such an indirect influence. I suspect this is the kind of thing that they are leaving wiggles for, and not some theory that the sun explains the totality of global warming. -Robert A.
