    Lily O Lady arrest the upward spiral we find ourselves caught within. Pinatubo being the most mild; Toba being the most extreme. I haven't seen those programs--sounds insightful, but the problem, I guess, without knowing more, is that in doing a risk assessment, our trajectory for the next several hundred years is one of warming. Volcanic eruptions that would reflect massive amounts of sunlight would certainly likely have a major cooling effect, but occur with much lesser frequency. I know the time scales are not good for proper comparison: the trend of global warming versus the spontaneity and sporadic nature of volcanoes, but in a horse race, I'm betting global warming every time for the rest of my life.

    Then again, Eyjafjallajökull did erupt in 2010 and caused a panic about a European winter, in a year which went down as the hottest in global history.

      the more polar a volcano it is, the less of an effect is has on the climate.

      ... which is what really drives home how staggeringly much gas Laki emitted in 1783-84  ;)
