re/ 23: there have been on average 60 major volcanic eruptions per year since 1960. depending on the duration of these eruptions, 23 doesn't sound so unbelievable. there is some *suggestion* that melting ice caps alter the stress patterns in the earth's crust resulting in increased activity: http://physicsworld.com/cws/article/news/42452 http://rsta.royalsocietypublishing.org/content/368/1919/2519.full http://rspa.royalsocietypublishing.org/cgi/collection/volcanology and i gather that historically, the end of ice ages was concomitant with increased volcanic activity.
