The issue of vulcanism and cool are of interest to readers of this blog and to me. Cooling and vulcanism seem to go together, but it is not clear what the real connection is. I suspect that a quiet sun can create conditions for eruptions. Not sure the mechanism. As Willis point out most cooling comes before the eruptions.

Richard Muller and the good folks over at the Berkeley Earth Surface Temperature (BEST) project have released their temperature analysis back to 1750, and are making their usual unsupportable claims. I don’t mean his risible statements that the temperature changes are due to CO2 because the curves look alike—that joke has been widely discussed and discounted, even by anthropogenic global warming (AGW) supporters. Heck, even Michael Mann jumped on him for that one, saying
It seems, in the end–quite sadly–that this is all really about Richard Muller’s self-aggrandizement 😦
And if anyone should know about “self-aggrandizement”, it’s Michael Mann … but I’m not talking about Muller’s claim that humans caused the warming. No, I mean the following statement:
The historic temperature pattern we observe has abrupt dips that match the emissions of known explosive volcanic eruptions; the particulates from such events reflect sunlight and cool the…
