When it comes to natural disasters, California doesn't have it easy. Droughts, wildfires, mudslides, The Big One, (and last but certainly not least), ARkStorm.
ARkStorm is more than just an ominous-sounding name. It is a storm that has happened in a historically consistent pattern, and one that would decimate the California economy as well as potentially that of the US and even the world. It would leave behind destruction, death, famine and cause mass migration from the US' most populous state. And, of course, it's being made more and more likely by anthropogenic climate change.
