Ask HN: What are some other potential worldwide crises like the pandemic?

Provoked by another thread which mentioned the Carrington Event. [0]

The Carrington Event was an extreme solar storm in 1859. It's estimated that a similar event today would cause trillions in damage.

It struck me that this was a little like the Covid-19 crisis. A sudden massive worldwide economic disruptive event, rare enough that we don't prepare for it, common enough that we can shake our heads afterwards and say we should have been better prepared.

What are some other things like this? Climate change is too predictable, massive asteroid strikes are too rare. A supervolcano?
