I think we have a dangerously false sense of security when it comes to social order. I mean, consider how little it would take to disrupt international shipping, let alone shipping within a country's borders or even to the next city.

What we'll likely see is an increase in short term interruptions in all sorts of services, including air travel, ground transport, etc., due to extreme weather, fires, and floods. If those California fires continue every year, wow.

What happens if those fires encircle LA and cut off I-5 or other main arteries? You know how fast the shelves empty when a typhoon is approaching, right? And that's in a place that is accustomed to typhoons.

Being stuck in an airport or Walmart parking lot for days on end does not sound like fun. (People who escaped the Paradise, CA fire ended up camping in the nearest Walmart lot for months.)
