    This overlooks the bigger problem; devastation of the power grid in a Carrington-level event. Who cares if you can't tweet or update your facebook when you don't have electricity to keep the food in your fridge cold, and neither do the stores. Generators will run out of fuel. No gas pumps work, so no replenishment and no deliveries to the stores. This outage will last for years as the grid gets rebuilt (if it ever does).

    Large cities will starve in less than a month. Mass numbers of refugees will flee, but they will find no welcome anywhere.

    Back in the days of Usenet, I read a discussion about this subject that estimated well over half of the world population would be dead in 5 years after the event.

    Of course, the Yellowstone stratovolcano could erupt, and that could be an extinction-level event.

    Happy thoughts.
