It sounds like a more immediate problem would be that all aircraft and spacecraft electronic systems would fail permanently? They wouldn't need to worry about the radiation doses.

It's possible to build shielded (up to a certain point of course) electronics and power grids, it's just a lot of work and money. Ideally, all new devices, grid lines, transformers should be made with at least some level of protection from those events. In a few decades world will not be a sitting duck anymore if follow this strategy.

I've wondered for a while. Lots of people seem to think a Carrington Event will simply fry all small electronics and make everything stop working, but from my understanding all it'll actually do is cause power surges in long transmission lines and disrupt wireless signals. Apparently telegraph lines sparked and shocked people. So what effect will that actually have now? Will a massive power surge go through my house…

The big risk is a bunch of transformers blow up, essentially taking the grid down. Since we would have to bootstrap the grid again without the advantage of the grid... this would likely set civilization back pretty far, a new dark age is far from impossible.

I believe you are very aware that humanity is able to worry about many different existential threats at the same time, right? CO2 levels, nuclear proliferation, Solar storm EMPs, asteroid impacts, each one has a different risk profile.

But sure...

I love this sentence. I am pretty inarticulate in person, sometimes I fantasise myself delivering lines like this in a hastily erected mobile command centre.

"In English, please, professor?" growls a FBI agent. My acolyte pushes their glasses up "uh... uh... if you consider these petroglyphs as a correlate of an instability in the solid inner core of the lower segment of the auroral-" the FBI agent pinches his temples and rounds on the eager young researcher, "You better start making sense, pencil-neck!"

I step gently in between them "In simple terms, we're talking about... a Miyake Event."

From my understanding it mostly effects large pieces of metal like copper lines but would be unlikely to create a significant charge in small electronics and wouldn't destroy solar panels or the vast majority of components. Any transformer pieces that are in a disassembled state prior to the event would be easy to put together and bootstrap any such event. Some locations like inside concrete buildings or under ground would remain insulated from the event as well. Also it's likely that at the equator no effect will be felt.

Yes, very sensible attitude. Similarly, when I'm crossing the road, I don't bother to look to see whether there's oncoming traffic, on the basis that I could be hit by a meteorite at any time...

Seriously, presumably you are aware that more than one thing can be a concern at the same time? CO2 levels are probably more of an immediate and addressable concern, in this particular case, but both should be a worry.

Earlier quoted context omitted.

In some respects it would have an opposite effect: no more Zoom calls; if you want contact with someone, go out and find them. Seems like it could require additional police presence, and they'll find it difficult to be effective without radios. We will need to look at centuries-old playbooks for virtually all aspects of life, temporarily. Hoaxes will spread without rapid fact checking.

It would also lead to the collapse of vital systems: transport, utilities, payments.... > Hoaxes will spread without rapid fact checking. They already do. I think you have found the silver lining: hoaxes will spread a lot slower.

It would lead to the collapse of modern society until/if we manage to rebuild it. Nothing in the modern world works without electronics and computers.
