Odds?
I think that if the odds of a Carrington event were that high - 12 percent at every solar maximum - we would have had one by now. And it seems like there should have been several dinosaur-killer asteroids since the rise of human civilization as well. So I think that science hasn't yet put the odds in proportion of the things we are now seeing with better detection.
But just in case, the world's governments should build deep underground metal-lined storage areas... where the obsolete computers that people keep throwing away could be stored. That way we could rebuild civilization more quickly after something like that! Computers that are 10 years out of date sure beat the stone age!
