Reflections on an Icelandic volcano


Since I am scheduled to go to Britain at the end of the month, I am watching the Icelandic volcano and the disruption of air travel with more than a little interest.

I have gathered from news reports that this is not a Krakatoa; it's just special geological circumstances and the location of the eruption that endanger extremely busy air routes. Would anyone care if this was happening on South Georgia Island? Besides the 2,000 who live there?

This incident, like the big icestorm that hit Quebec and eastern Ontario about a decade ago, underlines how we (OK, I) expect that complex structures we depend on will just routinely keep working, when there are all sorts of unlikely but perfectly possible catastrophes out there lurking. My favorite one, besides all the climate catastrophes, is a major solar flare that fries every satellite in orbit.

Sweet dreams!
