This kills all the satellites in our orbit as well? Satellites are already vulnerable to solar events and magnetic anomalies like SAA. In additional to everything on Earth being wiped out would this would create a mini Kessler Syndrome since all satellites are now space junk which we will never be able to communicate with again?

We can move all satellites to the dark side of Earth.

We can move a little less than half of all satellites to the dark side of earth.

This reminds me of the warnings about a coronavirus pandemic from over 10 years ago. We know from geological records that these are periodic events that happened every so often. We are due for one, and it is in our best interest to take the periodicity of nature seriously.

Exactly. We got pretty lucky (all things considered) with this particular strain. It could have been much, much worse.

I too would be interested to view these models. Coming from a rural background, people in my hometown still have gardens and hunt/fish. We're one, maybe two, generations removed from people producing most of their own food. I don't see how cities deal when they can't refrigerate food and the supply chain is interrupted.

Yeah, that's what I'm getting at. I don't see how it can fall apart of it's mostly self sustaining. There are still loads of people in my hometown that don't have power. What are they gonna lose if society falls apart? lol Lots of the local trucks run on vegetable oil so they don't even need a working supply chain for diesel. It'll be an inconvenience but it's no death. On top of that, a huge amount hunt and fish lik…

Where is this? I thought only a small amount of DIY types were running their cars on used veggie oil.

I’m continually shocked at how little people appreciate just how lucky we were with this recent pandemic.

After what Texas experienced, a dramatic reduction hardly seems sufficient.

I don't really get the "nightmare" consequences. Sure, some electric systems will go down / maybe burn down. But few people will die, right? When I saw nightmare in the title, I expected something like humanity will be wiped out, or maybe just 90% of us. Can somebody clarify?

There is a pretty simple test: attempt to go a week not using any tool, service, or person that relies on electricity or telecommunications even in the slightest little bit and see how you fare.

The doomsday people like to say we are 72 hours away from anarchy, and, if true, it will be the fallout from people instantaneously competing for very scarce resources that will be the real problem.

The more we depend on automation, the more vulnerable we are to power failure. Consider grocery shopping: what fraction of sales are online? What fraction in-store are card-based? Do the tills work offline, and if not, how fast can the cashiers work by hand? Does the store request resupply either automatically or via a manager looking at a spreadsheet, and if so, can the manager manage that without computer assistanc…

If everything falls like a house of cards in such scenario, does it mean that we are over-dependent on electricity? Im not a ludite but I would say thats better to have a plan B in such case.

I may have misunderstood how CMEs damage things, but I think the problem is the grid rather than the electricity? And even then, it could be designed around, but that’s expensive?

In any event, it is the kind of scale that only governments (and possibly Foxconn, Apple, Amazon, and Google) can really engage with.

If we would just 'move' our natural satellite to the bright side of earth, we could shield a part of earth.

What are the odds of having a (total) solar eclipse during a CME coming straight to earth? astronomically small for sure.

Depending solely on electricity is a bad idea. In a past weather event that lead to a power loss for nearly two weeks, everyone I knew was thankful to have piped natural gas. I am not sure I trust electric cars and fully electric homes to be sufficiently redundant.

On the other hand, car batteries full of energy would be useful while the grid was being brought back on line.
