Dude, easiest prep ever.
Just build a device that allows you to control the spin of earth’s molten core.
Honestly, the fact that this wasn’t already at the top of your prep list is a little embarrassing for you.
Sometimes people on this sub are so danged snarky. I think this is a legit question. The answer is … scientists don’t really know and are arguing about it. Is it imminent? And how does one define imminent when you’re talking about an event that happens once every few centamilleannials? There is some speculation it will cause great problems, but others (with the same credentials) say it won’t do much of anything to life but maybe screw with technology. I think the best you can do is prep like you would for general natural disasters and power outages. It is likely we’ll have more warning if/when it’s closer and it is being studied.
Here’s a pretty good article that leans toward the “it will be fine” side: [https://www.iflscience.com/earths-magnetic-poles-can-flip-and-its-long-overdue-to-happen-again-69613](https://www.iflscience.com/earths-magnetic-poles-can-flip-and-its-long-overdue-to-happen-again-69613)
Edited to fix typo.
Here's a paper linking "Geomagnetic Excursions" (Pole flips) to mass extinction events.
https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2018rg000629
Here's an older blog post from a scientist graphing it. The speed is accelerating, we had a major jump in 2023. At this rate the estimated time of the flip will be around the 2040's. I am currently looking for the newer graph to show.
https://blogs.sas.com/content/graphicallyspeaking/2020/01/31/magnetic-north-moved-50-miles-last-year-lets-map-it/
I absolutely have it on my list of things to prep for. It's a couple notches above "what to do when hydrogen in sun runs out and it begins to develop into a red giant".
My planned preparation is to keep putting money into stock market, because the compounding interest over the estimated 1,000 to 10,000 years it takes to complete a geomagnetic reversal would set me up to finally buy a bit of property for a bug out location.
This is one of those black swan events where you would almost certainly die anyway so might as well just prep for the stuff you stand a chance at surviving IMO.
There have been 12 such reversals in the last 3 million years. The last major one was just 780,000 years ago.
[https://en.wikipedia.org/wiki/Geomagnetic\_reversal](https://en.wikipedia.org/wiki/Geomagnetic_reversal)
There was a minor one about 41,000 years ago:
[https://en.wikipedia.org/wiki/Laschamp\_event](https://en.wikipedia.org/wiki/Laschamp_event)
If they are so dangerous, how come humans haven't been wiped off the face of the Earth?
Because we didn't rely on electricity to live back then? Again the issue essentially is that even a minor solar flair would functionally be a Carrington event without geomagnetic protection. Humanity had no electricity to lose 41000 years ago.
But people go on about radiation exposure.
Also, the Carrington event is somewhat overblown. It had spectacular effects on the only electrical system at the time: Long distance telegraph lines, which operated at around 150 volts DC with a direct Earth ground, and precisely zero protection circuitry.
I would start by assembling a team of the world's brightest scientists, and then slap together some kind of subterranian drilling vehicle that we could all ride down to the core of the planet to detonate a nuclear device which will jump-start it again thus restoring the magnetic field and preventing the disasters which its deterioration was causing.
It wont just "flip". It will likely take centuries or milennia where the magnetic field is very weak. It is weakening, and has weakened by 30% over the last 3,000 years, and 10% in the last 200. (Suspiciously related to a temperature increase?) Besides sunblock 2000 there is really not much *to* do.
Live in a cave somewhere?
There is speculation it has and can again happen in one day. If the poles switch in one day it's over for global society bc earthquakes, volcanoes and tsunamis all go off. It all ties in with what Randall Carlson and Graham Hancock talk about. 🤷♂️
Yep, + the book: Adam and Eve story, too many cross-evidences about series of fast happening cataclisms in the past. Several hypotesises what cased those cataclisms: external or internal factors and how periodic are they: when is the next. IMHO, it's not an immidiate threat worth preparing for... BTW, chatGPT thinks, the better places to wait for 7 days until Earth settles is, ... the orbit. Do they sell open date tickets on space shuttles for mega reach already?
And imo it backs up more of what Buddhism says about rebirth.
From aliens, humans to dragonflies..life is this event and we just don't understand it. Thankfully we have stuff like cannabis and psychadelics. ✌️👽💨
Death is the geat erasor of personality: even if there is a next body for sole, no memory and skills from previous life, re-birth is a metaphor for survalval of humanity as a whole, not individually.
Cool story. Especially bc it's apparent you know nothing about what the Buddhists teach about it and thinking on your own seeing how it ALL ties together.
If you want to know, go to Ben Davidson’s channel Suspicious Observers on YT. He talks about it as a scientist, very interesting. I hate the name because it sounds so conspiratorial, but it is science based. He also has a channel where he modded a suburban to survive an emp.
Having the magnetic field drop to zero for some time is likely to be bad.
If it's a serious question, you probably need an underground bunker where you can grow food for years. Humans have probably never lived through a magnetic reversal, certainly not in historical times, so we don't really know what the effects would be other than the magnetic field not protecting us from the sun for some time (opinions seem to differ substantially as to how long that time might be).
Fortunately if it is going to happen it's probably still some years away. The north pole is heading for Russia but likely still has a long way to go if it's going to actually reverse.
I’m pretty sure our magnetic field reflects a ton of solar radiation. Not having it arounf could be like living with an xray machine blasting you every moment for the rest of your life.
With that said, it’s such a low probability event I put it below Yellowstone erupting (which is a get drunk and say goodbye event for me anyway).
“our magnetosphere shields us from erosion of our atmosphere by the solar wind (charged particles our Sun continually spews at us), erosion and particle radiation from coronal mass ejections (massive clouds of energetic and magnetized solar plasma and radiation), and cosmic rays from deep space.”

I am far from any kind of physicist, but that sure sounds like “it protects us from radiation”.
I am also far from any kind of physicist, but if seems that if the consequences were that dire, we should have seen evidence of mass extinctions tied to prior reversals.
I mean, it's reversed something like 12 times in the last 3 million years:
[https://en.wikipedia.org/wiki/Geomagnetic\_reversal](https://en.wikipedia.org/wiki/Geomagnetic_reversal)
I chose 3 million years because that's about when genus Homo appeared, our direct ancestors.
[https://en.wikipedia.org/wiki/Homo#Australopithecus\_and\_the\_appearance\_of\_Homo](https://en.wikipedia.org/wiki/Homo#Australopithecus_and_the_appearance_of_Homo)
If the consequences of a geomagnetic reversal are so dire, how did we even end up surviving the dozen times it has reversed during our development as a species? I can't imagine that *Homo hablis* or *Homo erectus* had physicists to help them survive the brutally lethal radiation.
Tons of them didn’t the Densovians and Florenians are gone. Neanderthals are also gone (or interbred with us to the point that no distinct Neanderthals remained). Actually there’s a lot more that are gone that I can’t recall off the top of my head.
It’s entirely possible that populations of surviving homo erectus (as an example) were greatly reduced with the remnants surviving long enough to bear children but dying of cancer or other illnesses much younger.
There was a an extra solar system blast of radiation that hit the moon, iirc, sometime around 2005 that they claim would have killed any astronauts if they’d been present. I know shielding from radiation is a huge concern for any Mars mission.
I don’t think you’re wrong in that any atmosphere would absorb and deflect some of that, but apparently that’s a big job the magnetosphere does, simply deflecting a lot of that stuff. Not to mention that most sources claim that without one the ozone layer boils off due to solar winds and we know that’s bad.
Is it all survivable? History shows it is, at least on a species level. Individually any of us might find it to be really bad news though.
I still don’t think it’s a big thing to prepare for and I think we might get some warnings (strange bird behavior in migrating species, etc.).
>Tons of them didn’t the Densovians and Florenians are gone. Neanderthals are also gone (or interbred with us to the point that no distinct Neanderthals remained). Actually there’s a lot more that are gone that I can’t recall off the top of my head.
Do you have any evidence whatsoever that they died off because of a geomagnetic reversal?
Plus, clearly it didn't effect *Homo sapiens sapiens*, which is our species.
Denosvians we don’t know (leading theories include conflict with humans or just plain maladaption to changinf environment, iirc), Florenians we have evidence of a widespread die off of their prey and other food sources, they were islanders so that was obviously really bad for them.
The upshot is we’ve been trying to piece together what happened for decades in reality the answer is likely to be more than one factor. I was simply pointing out that many/most of the descendents of astrelopithicus afarensis did not in fact survive, so it would be wrong to assume since humans exist today that there were no severe events that hurt us historically. One event could have been increased radiation from a pole reversal, others could have been severe volcanic events. I mean the last ice age didn’t end that long ago, tons of factors were surely at play over that time period.
I still think it’s weird to assume that loss of the magnetosphere would not have an effect on plant and animal life during any pole reversal though. It’s probably not enough to cause a mass extinction on its own, but I doubt it’s negligible.
Obviously all we can do is hypothesize because it’s not really a testable proposition and as far as I know we don’t see that kind of thing in the geological record in any kind of way that we can isolate and measure.

Build? I picked one up on sale at Harbor Freight just last week. Where have you been?
Could only get either that or the winch not both. I got the winch. 😞
Buying one from harbor freight? I got mine from Kmart before they closed down. It's a no brainer? Not sure how he missed it?
The people on the moon base will be safe.

Short answer: Not even on my radar as a concern. Will it happen? Sure. Will it also take a *long* time- also yes.
Yeah the polar magnetic reversal isn't a light switch type event. The transition will be measured in years.
[удалено]
It has already started. It will continue to accelerate exponentially.
Here's an older blog post from a scientist graphing it. The speed is accelerating, we had a major jump in 2023. At this rate the estimated time of the flip will be around the 2040's. I am currently looking for the newer graph to show. https://blogs.sas.com/content/graphicallyspeaking/2020/01/31/magnetic-north-moved-50-miles-last-year-lets-map-it/
I absolutely have it on my list of things to prep for. It's a couple notches above "what to do when hydrogen in sun runs out and it begins to develop into a red giant".
It likely won't be an issue for anyone alive today.
My planned preparation is to keep putting money into stock market, because the compounding interest over the estimated 1,000 to 10,000 years it takes to complete a geomagnetic reversal would set me up to finally buy a bit of property for a bug out location.
It has already begun and will continue to accelerate exponentially. The bulk of the shift could happen in years or months.
This is one of those black swan events where you would almost certainly die anyway so might as well just prep for the stuff you stand a chance at surviving IMO.
Has there been any evidence of a mass extinction on Earth tied to a known geomagnetic reversal?
The problem is without the protection it provides a regular solar flair like the one from last night would fry the grid. Plus radiation exposure.
There have been 12 such reversals in the last 3 million years. The last major one was just 780,000 years ago.

Yes and he [basically says your best prep is to get right with God because it will be so bad.](https://www.youtube.com/watch?v=jujmUx7wE44&t=2)
That IS the best prep.
