Volcanic winters are far more frequent than catastrophic asteroid blasts. Disregarding a volcanic winter possibility and its impact is like disregarding the possibility of a pandemic.

> Volcanic winters are far more frequent...

True. But if you're working in public policy in a vaguely-democratic country, and trying to get anything useful done - then the public feels vastly more familiar with "giant asteroid wiped out the dinosaurs" than with volcanic winters. So, just like "Zombie Apocalypse (wink)" disaster prep - you go with a "close enough" scenario which lets you achieve some actual preparation.

536 and the Norse stories about the Fimbulwinter ought to be argument enough.

For the 1% who are so interested in science & history & such that learning about those would not be an issue, plausibly yes.

For the 99% - who don't have the time, or interest, or attention span, or cultural identification, or whatever, to sit through all that - NO.

Is your priority further education of the 1%? Or to actually get some large-scale public disaster prep done?
