Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
the worst-case scenarios -- such as the possibility that a nuclear explosion might ignite a chain reaction of methane hydrate eruptions that could result in the most horrific global catastrophe since the Permian extinction...

Call it the BP Extinction Event. The quantity and proximity of methane hydrate deposits would surely be a consideration. Does anyone know of the relative ages of the oil deposits and the Chicxulub crater? The formation of that crater was surely vastly more catastrophic than any sub-kiloton nuke thousands of feet below the sea floor could be.
