A Carrington event level impact will be quite a disaster, and it's only a matter of time. But if that's not bad enough for you, look up Miyake events. Seemingly far more devastating in what it could do to a technological society, and we don't know what the source is. Doesn't seem to be the Sun as it doesn't line up with other things. And we're within the time range for another one, given when the last few ones were based on evidence.
