Cataclysmic risk: Volcanoes instead of "Global Warming/Climate Change"

Volcano risk
The whole context of this link reminds us that no matter what risk you prepare for there is a high chance that something you never expected to happen will be the dream wrecker totally bypassing your preparations, and so goes risk on a national and global scale.  Imagine all the work done for global warming and climate change gone to waste as a meteorite or a monster volcano takes out a whole continent and darkens the skies for years leaving hundreds of millions to die of starvation.

Some things you can't adequately prepare against but setting aside food, water, and a means to hold onto these preparations are a sound strategy for surviving many different threats.
