As much as I don't like to use Wikipedia as a source I think it has a fair summary: http://en.wikipedia.org/wiki/Little_Ice_Age I really don't have time to dig further.... Basically, yes volcanoes contribute, but they were only part of the problem. The more important thing to note now is that even if we had dozens of volcanoes there not going to compensate for mankind's activities of the past 100 years. On 11/6/07, Michael H.
