Big solar flare. Grid goes down. Could take years to get it back up.


Near miss in July 2012: https://science.nasa.gov/science-news/science-at-nasa/2014/2...

We're near a new Maunder minimum, so becoming less and less likely.

Also, while I think a big solar flare would break a lot of stuff--- I think we're better prepared for it than many give us credit for. Tens of millions of people might be initially without power; some fraction of them may need to wait for a long time (months or even years) to get it back; and various bits of transport and production may get disrupted. Enough to require rationing and a major pain to quality of life, but not enough for any kind of catastrophic chain reaction, IMO.

Interesting, thanks
