“The exercise was held from May 8 to 9, 2024, at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and at a Federal Emergency Management Agency (FEMA) site in Denver, Colorado.”

im just not gonna worry about the sun
They said we weren’t prepared for a pandemic, either.
Shit we gotta fix this.
Man you know it’s bad when you’re rooting for this or a civil war or nukes. Just to reset everything. I’m so over being an American.
If it makes you feel better, even if you migrate to another country and gain citizenship, you still have to pay income taxes to the US.
If the country has a bilateral tax agreement with the US and your income is not high by middle-class standards, you can deduct the foreign tax from the US tax. Foreign tax is typically higher if you’re anywhere in Europe of the developed world (leaving out the Gulf countries and Saudi Arabia). You still have to file in the US, which is an inconvenience and an expense, but you’re unlikely to be double-taxed.
You won’t have to pay anything unless you’re pulling in the equivalent of >$126,500 USD in foreign income. Then you’re taxed on what you make above that. My H&R Block lady here in Germany told me all about it when I file every year. And boy howdy is fuuuuucking stupid that I’m having to file US taxes every year. I could stop, but then everything falls apart for me.
You know those stories where the world is reduced to a post-apocalypse after a natural event? What if that’s only what happens in the US, and the rest of the world recovers with ease due to extant rescue services?
Oooh, so that’s why apocalyptic movies are almost always only US oriented
There are A LOT of BIG countries with big electric grids in the world today. Which countries GRIDS get hit the worst depends on which side of the Earth is facing the ‘hit’. Could the West (US, Brazil) or Europe or the East (China, India).
It is a little more complex than that. You cannot only consider how big is a country or how big is its grid.
If the Europe would be hit by a solar storm, assuming that not all of it was hit we can recover the grid in about a month and the blackout would not be longer than maybe a week.
But a solar storm would destroy also everything else, so how big is the grid is really irrelevant when you basically have every other piece (excluded the few hardened enough) destroyed.
If it wasn’t for the stupid Darrel Dixon show, my head canon of the walking dead only affecting America would still stand.
They literally just walk, and it would be pretty obvious that everyone is infected after the first year or so of people dying from the flu and shit. Any country with competent leadership could have squashed the zombies in a couple months.

True but you underestimate people stupidity.
I’ve always thought that if I’m in a zombie apocalypse im just gonna carry super soakers filled with hydrogen peroxide
After experiencing the covid-19 outbreak I am now fully convinced that a zombie apocalypse is feasible, there would be people denying the existence of the zombie virus, just going to the infected an getting bitten because they wanted a pizza or something, that and people just drenching themselves in bleach or something because they heard that keep the zombies away from some dude online. Stuff like that.
Isn’t that the case in the 28 X later series? Like England fell to a zombie apocalypse but the rest of the world is doing fine?
…and simply agrees to never, ever, set foot in North America again. I’m not sure how this ploy works work out for our fine fellows in South America and Canada, the ones currently belabored with being the closest neighbours to The Wastelands.
I’m in.
Not sure, though, how this ploy would work out for our fine fellows in South America and Canada, the ones currently belabored with being the closest neighbours…
Fuck Mexico, I guess.
Just uhhh… Build a wall, I guess?
Don’t look up
I’m not a doomsday prepper, but stuff like this makes me want to sequester some gear…
I don’t think it will matter. We need modern logistics to produce and get food to people. Without that 90% of people will starve in the first few months.
It’s good to have supplies for regional disasters and events that only last a few weeks or months. But if the national grid is going to be out for a year or more and things like fuel and food can’t be transported and stored at key locations then it’s all going to shit.
A hundred years ago most food was grown a days walk away from a person. With no Diesel production or distribution, which some flairs knock out, there is no warehouse refrigeration.
Even with reserves, there are spare parts drying up. Trucks, ships and planes need constant work.
Some areas would get by, grains and beans can be moved without all that. Probably a huge percentage would survive. Barely
I have an old safe where i keep some old tech and power banks - just junk really but the Faraday is enough for any solar flare and i think it looks cool. Not sure what good that would do if all cell towers and satellites are fried though. Even fiber is unlikely to operate as I imagine most switches are not secured.
Last time I did research on this I came out entirely unconvinced of value of prepping here. Just the usual water, gas stove and bags of rice is really best bet and invest everything else back to local communities because economies of scale kicks ass.
the Faraday is enough for any solar flare
Faraday cages are useful. But CMEs are not solar flares. They are very different (though sometimes loosely correlated) phenomena.
During the recent Iberian Peninsula Blackout, which in practice meant a whole day without power and most of it without water, thanks to a past phase of mine as a bit of a prepper I:
Anyway, my point is not to go full prepper, my point is that some elements of that minset and practices will cover the kind of far more common problems with will leave you without power and water for a few days.
One thing I did find out is that I probably need something like a solar powered powerbank for loading my tablet since that’s how I mostly read books nowadays (didn’t actually need one in this blackout as it was of just a day), so I’ve ordered one.
Little things that mean you don’t actually get unecessary stress in a situation like this.
It’s not something that is going to save you from nuclear holocaust or in general the collapse of human civilization, but it will save you from spending days without food or water or the stress of not knowing what’s going on, such as in such a long and unsual blackout, a flood or other similar more frequent catastrophes.
Do you replace the power banks to keep them charged to 70%? Maybe also add some ham radios and walkie talkies to the stash.
you cab use it unless you have it.
get what you need, take what you want.
lol we couldn’t even prepare for fascist takeover of the country. why tf would anyone think we’d be prepared for a solar firestorm
Invest in metal stoves and big tents today!
Im starting to think the fermi paradox is based around what philosophy it follows. "Efficiency" like lean or robustness like six sigma.
If a transmissions company tried to spend money preparing for a disaster like this, their shareholders would sue them into the ground and lobby to make it illegal to acknowledge the existence of the sun.
Prior to Trump and his saboteurs getting into office, US grid operators were pretty good at planning for these events.
I mean, having a tested and proven DR/BCM plan is kind of an important part of being a serious business…
I’m glad this threat is at least starting to be taken seriously. As an amateur radio operator, I got incredibly interested in how the weather on the sun affects radio propagation and power management here on Earth.
Better a CME than an EMP just simply because there is at least some time to prepare for a massive CME. Whereas an EMP has absolutely no warning whatsoever.
In the event of a massive CME off-grid homes and buildings are likely to fare much better because they are not connected to the power grid. The problem comes with long transmission lines where incredibly large charge differentials can build up over distance. shorter wires can’t build up nearly the same amount of charge differential
As an amateur radio operator, The high bands get wiped first! 80, 160, not so much (no ionosphere? ground wave still works. Easy to throw up a long wire … afterward). Hams (esp. ARES) will become VERY IMPORTANT for a LONG time when it happens. Field Day is a good way to prep for aftermath. (Gear can go into metal containers to escape parts damage until afterward.) Portable generators (best without a lot of electronics on them) will be needed to re-charge the batteries!
It’s worth noting that even though a building might have solar, the systems usually disable themselves in the event of a blackout to prevent back feeding into the grid.
That wouldn’t be an off grid building then.
That’s known as a grid tie system and my edit mentions that. The only way it’s going to help is if the grid is physically disconnected from the building as in the wire is not connected to the building at any point.
Note: “Would Be a Catastrophe” even back when the agencies involved in mitigating the disaster still existed.
Oy. I really don’t want to see what happens when we’re faced with an actual challenge. This is… yikes.
It’s all right, Trump will redirect the solar flare by drawing a new line on a chart. Plasma is very accommodating as everybody is well aware.
I would get a case of beer and go to the library and read until the internet was back on. You can’t stop my escapism that easily.

good thing we got rid of fema in 2025 then
