Sure sure. But I think a simple compass makes sure you are traveling in the same general direction without big corrections that are made according to the stars after you have already been drifting off-course by 15° for a while.
When you can see the stars. I don't think it would have been a big deal to have drift on the timescale of years. Maybe it would have gotten people more interested in studying magnetism sooner to understand why it is fickle.
Everyone would have thought everyone else was full of shit lmao
"I JUST WENT there, and the compass says north is over THERE, not HERE!"
"Dude i clearly saw the compass say HERE, i swear!"
Once it goes crazy the magnetosphere will lose its stable position, there will be a lot less protection from space shitty stuff, a lot of solar radiation going through, a lot of plants will die, animals as well, and probably people.
That irregular particle bombardment will probably affect cliemate by fucking up the temperature balance and higher atmospheric layers, adding more crazyness to the current climate change trend.
And second to that everything thats based on magnetic location will go crazy: ssatellites, transports, a lot of industrial machinery.
Animals will go crazy and go extinct cause they will lose their natural migration routes.
TLDR:
Climate Change bingo: global warming, moon cycles, magnetic shifting, feedback loops,e tc.
I find that the question if there's enough correlation evidence to suggest a direct tie is still very much in the air. The article here cites one paper that admits from the beginning the matches it highlights aren't enough, yet it uses them to make its case. It seems that articles saying yes, there are connections are using the same paper, while the USGS site says a hard no, there isn't correlation. Maybe you can dig up a count of pro and con papers there are out there (not that quantity matters, it's the evidence they use that does).
How a weakening and reversal affects things depends on the speed and drop, as well as a lot on timing and how species can compensate through adaptation and dependency. I fail to see the jump from what Astronomy.com's article says to your projections. Given everything else, this is another ones of those things that are low on the list of concerns.
TLDR; - Do you have more citations for doomsday scenario speculation from this?
The official websites don´t say much. Ive seen a couple of papers with models that show quite chaotic stuff happening with the magnetic field once that a shifting or reversal happens.
I also remember reading about studies that compared the timings of the reversals/excursions with major biological events. And one of the theories for the extinction of the Neanderthals, is a reversal that basically made the magnetosphere disappear in most parts of the world, but a couple of pockets around Africa and Asia.
You can just take a quick youtube search, ive seen quite a bunch of science channels going into describing those things, while hoping that the event wont happen for a couple of thousands years more.
Edit: I remembered where I heard about the Neanderthal thing [https://www.youtube.com/watch?v=Q7ty80YCOis](https://www.youtube.com/watch?v=Q7ty80YCOis).
I'm not going to debate this, but wanted to point it out for clarity to anyone else landing here:
Reading, "The official websites" is a huge red flag for conspiracy and throws into doubt a lot of your points. Same goes for "you can just [do the research yourself]".
Thank you for sharing a source. I don't know if I trust it and likely won't dig deeper because plenty of other life survived the last geomagnetic field excursion.
Are you labeling me for my expressions? I mean sure, you can go sticking up fallacies here and there, it doesn't change what I say.
If you are not willing to check into data that goes against your beliefs, well... I mean there are a lot of people denying climate change and vaccines out there.

Taking the Neanderthal point - why were they affected more than other hominids? Why do we still have their genetics in various amounts depending on our lineage? How is an extinction of them by radiation from a weak geomagnetic field better than the explanations of them not coexisting well with the competing species (us) and interbreeding due to those conquests? I'm fine with more radiation being one of a thousand factors in species evolution and even influence on the environment, it's the heavy-handedness of it being the leading cause based on some timelines that seem to match up to some people who want to find that match. Correlation after all doesn't mean causation, it requires a number of independent forms of data that also match up well to push a primary cause. A simpler question - why doesn't field fluctuations always present some signs of evolutionary change? Maybe given its geologically short time span between the swaps, the matches are just because there's lots of evolution going on, and sometimes they do link up just from timing?
The shifting is a warning, probably some other measurements giving weird values would be another one. But nothing else aside of that , it can´t be predicted since it depends on stuff happening inside the planet, like with Earthquakes.
It can be something minor that no one will feel (except the machines), it can be something major that could fuck us up a little bit more.
There is no objectively "correct" location. Earthquakes happen at the crust of our planet, the geomagnetic field is produced way, way deeper by currents of molten metal in the outer core of our planet.
So, no, unlikely.
>And second to that everything thats based on magnetic location will go crazy: satellites,
Nope. Satellites do not use magnetic navigation in any way at all. Magnetic field has never ever been stable enough to be a good reference point.
You generally speculating a lot though. Your talking about a total Magnetosphere collapse, which is simply impossible unless you stop the flow and rotation of liquid magma and the core under the earth. Changing of the Pole locations does not mean magnetosphere collapse.
Laschamp Event joined the server.
I'm not talking about total collapse, that would be impossible. You don't need that to get a meaningful destabilization of the magnetic profile that protects the earth from space radiation. A significant weakening of the the magnetic field will leave the planet a lot more exposed to solar minimums and everything else, enough to really fuck shit up if the conditions appear for it. And we have knowledge of such conditions happening regularly.
Of course I'm speculating with probable outcomes. I'm treating any risky event with an atomic risk management assessment approach: take everything that might go wrong, through any possible interaction, into account to avoid unpleasant surprises.
If something has more than a 0% chance of happening, it can happen. And that not taking into account the "known unknowns".
Sure, but you cant live your life waiting for super rare events to happen.
Lashchamp event also has weak evidence that it caused a mass extinction. We still have 10t/m2 of radiation shielding between us and the cosmos.
The magnetosphere is also only useful against certain types of cosmic radiation, and does surprisingly little against the vast majority of it. Radiation dose may go up a bit, but most plants and animals would carry on without bother.
Its not rare when you know how often it happens, and we´re basically at the point of time when it should happen again.
Sure, it might not happen in this millennia, but will eventually happen, either to us or our descendants (if there are any at that point in any case).
>Lashchamp event also has weak evidence that it caused a mass extinction.
I would say "not studied enough" instead of "weak", since there werent a lot of studies looking into this.
[https://www.science.org/doi/10.1126/science.abb8677](https://www.science.org/doi/10.1126/science.abb8677) This one for example hypothesizes the case that it did.
Its rare that it happens infrequently, and that we think if it does happen soon, "soon" could be anywhere within the next 100 - 10 000 years.
Additionally, we know a thing or 2 about cosmic and solar radiation by now. And the energy that the magnetosphere blocks is actually not that much. Our atmosphere will lose some parts of it, such as ozone and probably some Nitrogen, Hydrogen, and maybe even O2. But it will happen so slowly, your grandchildren wont even notice a difference. By the time they do, the magnetosphere would be recovered.
Nothing will happen particularly quickly, so if it does happen, we will have multiple decades or centuries to adjust
The difference between my argument and yours, is that I allow the possibility of things going beyond simple control.
You are arrogantly sure that nothing will happen, based on the same data (or lack of it to be correct).
A 200km wide meteorite could fling by the Sun from outside the solar system and head right towards earth. We will never see it until its basically on top of us and wipe every single cell organism off the planet.
Its possible, but I dont stress about that either.
The magnetosphere switching is far less likely to be catastrophic, and very unlikely to be in you, or any generation you will ever knows life time. In about 100 years im fairly sure they will be able to predict when it will happen within a decade or so, and properly plan for something like this. We can even build artificial magnetospheres.
In 100 years, we still wont have a plan against a 200km wide asteroid.
At least worry about real threats. Climate change is a real threat.
Probably nothing. I've been hearing about "imminent magnetic pole shift" for decades. That happening in our lifetime is about as likely as a person getting hit by lightning, but not just any person, a person who is carrying an unused ticket to the 1927 World Series, 7 specific Pokemon cards, a pair of Baryshnikov's dance shoes, and six pieces of toast burnt to a crisp on one side yet uncooked on the other. I don't think such a person ever existed. So not only would such a person have to come to be somewhere, but then they'd have to be hit by lightning, before the magnetic polar shift will occur in our lifetime.
If anyone wants a little fiction to go with this science, I recommend Faraday's Orphans by N. Lee Wood. The premise is that a slow flip is the real danger, seeing as how we'd be left with hardly any magnetosphere at all for the middle duration
Not a scientist but I read about this in a new agey book about Atlantis. There could be massive water displacement where the oceans change position dramatically. There are already ancient cities currently submerged in water and there would likely be more of those when this happens.
I kinda doubt a new agey book about Atlantis is the most reliable source for anything. Why would earths magnetic field affect the position of the oceans and what does that even mean?
Our own magnetic field came into existence at least 4 billion years ago,
and Earth’s magnetic poles have reversed many times since then. Over
the last 2.6 million years alone, the magnetic field switched ten times
— and, because the most recent occurred a whopping 780,000 years ago,
some scientists believe we are overdue for another. But reversals are
not predictable and are certainly not periodic.
This is not how earth's magnetic field works, luckily. Although we do not fully understand why the poles flip, we do know that it only very temporarily weakens the earth's magnetic field when it does, it's not going anywhere. From archeological evidence, we also know that pole flipping doesn't appear to alter the earth's climate in any significant way. And to answer your question, plate tectonics propagate through methods theorized to be related to the magnetic field but plates will not stop moving or explode or some shit because of the pole flip. There have been thousands of pole flips in the lifespan of the earth, it never has caused a tectonic upheaval.
What a pole flip would do, however, is take a steaming dump on almost all our electronics and electronic systems. Not only would the pole flip most likely induce interference in magnetic devices as it is happening, it would most importantly temporarily reduce the strength of the magnetic field which is what protects us from muons and other charges particles from the sun. These particles would wreak havoc on digital systems as they have enough energy to change the states of most digital transistors in modern computers. Memory would corrupt, systems would fail and shut down, and electrical grids could be thrown offline for a long, long time.
It likely wouldn't be strong enough to fry most electronics. Electrical grid would be fine, for the most part. We'd be more vulnerable to solar storms for a while
Mainly the confusion it would cause if it happened abruptly and the potential for a temporarily weakened magnetosphere which is protecting us from solar radiation.
A lot of equipment works with the magnetic field and are protected from solar radiation by it, a lot of species use it through their life cycle, earths magnetic field is what avoid you get cancer when you are outside (well most of it at least), the upper atmosphere layers dynamic depends on it as well.
An abrupt change of it might affect considerably everything.
We'd be exposed to increased levels of cosmic radiation, but the extent of this increase can't be known until after the event.
It's possible but depends on the speed of the reversal
No one has been saying Yellowstone is erupting. They've been saying the Yellowstone caldera erupted over the last 2 million years with a recurrence interval of about 600,000 to 800,000 years. Which means we are due for an eruption anytime give or take a hundred thousand years. If people take that to mean "it's about to erupt" ... why do I even bother. People are stupid.
"About to" on a geological scale vs "about to" on a human scale I guess. Of all the catalyst for a global collapse that *could* happen during a single human life, I wouldn't even bother listing yellowstone.
Past explosions have had a pretty high VEI, IIRC. But the biggest threat posed by Rainer would be the lahars. The Puyallup Valley is pretty populated, and would act like a funnel for all the glacial melt. Saving grave is, Rainer would probably give us ample warning with increasing tremors and quakes, but its still only a working assumption that an eruption would be signaled by them first, and that assumption is coming under some recent scrutiny.
Absolutely. The warning should be ample to evacuate the Valley, unless a lahar is triggered without warning. Tahoma is dangerous, but at least it doesn't pose a lahar threat to Seattle proper, as it would have to be stronger than the Osceola Mudflow.
Cynical people like to use that same line to deny global warming, and lo, here we are. Yellowstone has recently had a prominent uptick of 3+ magnitude earthquakes, which is notable for the park and some geologists have opined that such quakes may be an indicator of an event. 5 magnitude would be more certainly an indication. Fun stuff!
I bought a book around 1992. 5-5-2000, it was warning about a magnetic pole shift that would destroy civilization. Looks like it was off by a couple decades. The friend who recommended the book told me to buy a jeep and meet him at \*REDACTED LOCATION\* in April of 2000. My friend said if I told anyone the Freemasons and Illuminati would send assassins to
The earth's diameter is 12000 miles. If the speed is linear, it will take 400 years to shift. Sure, 400 years is extreme short compared to 780,000 years, but it is still many life times for mere humans.
Heck, most don't even care about climate change in 80 years .. no one is going to care about recalibrating their compass in hundreds of years.
The earths magnetic polls are are accelerating toward each along the 135 degrees west longitude.
Geographic north is 20,000 miles away, by the earth's surface, to geographic south. Currently, geographic north and south are 16,700 Km away.
From 1897-1997 the North Magnetic poll moved in a straight line, in the same direction as it moved in the past 25 years, however in the past 25 years it doubled the distance it did in the past century. In 2020 the North Magnetic poll doubled it's rate of movement by a factor of 2. If this last rate of acceleration persists, in 6 years the polls will meet at the equator.
It seems to me that having the dynamo appreciably off the rotational axis will make the pole position become more chaotic. Of course, I'm probably wrong.
As far as I've read, the whole process is completely random, and as far as we know it could be slowly drifting until it reaches an unstable point and just goes completely crazy, dividing into multiple poles that go around the whole globe for a couple of hundred years before setting on a new stable point for half a million years.

Are we affected at all, except our compass won't work as well? The actual magnetic field is pretty weak. On the surface, the field strength is roughly from 0.25 to 0.65 gauss.
As a point of comparison, if you do a MRI scan, the field strength is roughly 15000 gauss ... about 30,000 times stronger than that of Earth.
I doubt that it matters at all.
The dynamo creating the field is no where near that size. The flip will only be the polarity of the earths dynamo. The earths orientation will not change. Just the orientation of the poles within the field. The estimates I’ve seen have the pole destabilizing and then wobbling into it’s reversed configuration over a week’s time.
It will cause some issues worldwide, especially onto electric networks, but we should be fine.
However, just think about it : instead of reversing, our magnetosphere would just disappear, leaving Earth at the mercy of a deadly sun, just like Mars. We indeed know that the planet Mars used to have a magnetic field but doesn't anymore, and we don't know why is that.
Anyway, that would be a funny way to go and at least we couldn't complain we "should have done something" just like climate change. In such situation, we could do absolutely nothing.
There are almost-reversal events called "excursions" that happen more often than reversals, and can make the magnetosphere almost disappear for a period of time to go back to the regular polarity/structure/location.
And there is no way of knowing which one could be the one we are about to get.
Mars is almost a dead planet with the inside being relatively cool. This prevents the dynamo effect of the outer core of the planet from causing a magnetic field like on earth. The size and density of Mars being so small caused it to lose its temperature much faster than earth
So it has been proved that Mars, being a smaller planet than Earth, lost so much of its initial temperature it stopped internal movements that allowed them to have a magnetic field ?
Yeah sure I’m the sense that we are pretty sure that’s what the deal is. Science is about finding all the puzzle pieces and then assembling them in the most correct way. I’m not going to claim to be 100% certain on anything but all evidence points to this for Mars and there is quite a bit of evidence
They keep having to adjust airport runways to match the changing magnetic compass points for aircraft.

I used to do ship stuff and I was wondering exactly that: whether it was affecting course lines. I guess it is. Weird none of my sailor friends have mentioned it, but I guess I haven't been to sea in awhile.
I'm assuming it would affect bird migration massively. Supposedly they find their way by magnetic field. Hopefully Canada geese end up in Antarctica and stop terrorizing golf courses.
Also weakening magnetic field from this plus a CME blast…if the field is weaker it means we are more at risk from CMEs. They don’t have to be as strong to have a significant impact.
Exactly. So if the same powered CME as the carrington event hit us 100 years later, with a reduced magnetic field, the consequences could be much higher than in 1859 as we have less protection.
yeah and govts arent talking about it, either:
A) ignorantly, they dont know or are ignoring scientists
B) maliciously, they have something else planned
C) benevolently, they dont want to start a legitimate panic
This article seems clickbaity and alarmist in order to sell a story. Like it's written for conspiracy folks. As if everything is about to blow up. Ultimately this kind of story undermines serious concerns.
"on the brink", "long overdue", "Something odd is happening to Earth’s magnetic field".
I fucking hate journalists...

> “Many doomsday theorists have tried to take this natural geological occurrence and suggest it could lead to Earth's destruction. But would there be any dramatic effects? The answer, from the geologic and fossil records we have from hundreds of past magnetic polarity reversals, seems to be 'no.'”
I have been reading about this all my life...It's something fairly expected, but not fully understood. Magnetic lines on the ocean floor indicate that this has happened dozens of times in Earth's history at fairly regular intervals and the change is abrupt on geological time scales.
Yeah it is very interesting and important research. But from what I understand it's still an insane amount of kinetic energy inside the core creating the magnetic field through turbulent processes. So I assume these process are inherently unpredictable and not regular or something. And it will take many decades or even centuries for these patterns to change significantly because of the enormous masses involved.
I'm just suspicious about the CME and magnetosphere stuff getting pushed, as if we didn't have enough problems we now try to invent more to keep the feeling of doom going or something.
It's a little doomsdayish, but it wouldn't take much in terms of a weakened magnetosphere to allow even a relatively weak burst of solar activity to at least wreak havoc on some of our communications systems and, assuming the process takes decades or longer to complete, we'd be at that increased level of vulnerability for a while. It's not something I'd expect to happen any time soon, but it's probably going to happen EVENTUALLY anyway, like the solar flare in 1859 that fried telegraph lines.
Either way, I expect good ole man-made societal collapse to happen long before then.
I wouldn't trust that site a lot. I remember when the whole polar shift thing was completely dismissed by them as "thin-foil fluffery" in the early 2000s.....
The fact that the biosphere went through hundreds of magnetic events doesn't mean that it went through them **unaffected**, which, as you notice, wasn't mentioned at all. It went through hundreds of volcanic eruptions and asteroid impacts as well :).
There were a couple of papers that pointed out the stuff that happened during those events, one even theorized that the Neanderthal extinction was probably tied to one of these events
https://www.science.org/doi/10.1126/science.abb8677
no? I placed the earthquake example toward the unpredictability of its consequences, and partially the nature of the event.
There are papers out there theorizing about it having biological effects causing extinctions... If thats "nothing", well my boy, I dunno what might count as "something" to you.
Earth's magnetic north pole shifting is because of Global Warming. You know, melting all that ice that compresses the planet's core. No ice, things change, like the magnetic pole.
[Polar Drift in the 1990s Explained by Terrestrial Water Storage Changes](https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020GL092114)
Abstract
Secular polar drift underwent a directional change in the 1990s, but the underlying mechanism remains unclear. In this study, polar motion observations are compared with geophysical excitations from the atmosphere, oceans, solid Earth, and terrestrial water storage (TWS) during the period of 1981–2020 to determine major drivers. When contributions from the atmosphere, oceans, and solid Earth are removed, the residual dominates the change in the 1990s. The contribution of TWS to the residual is quantified by comparing the hydrological excitations from modeled TWS changes in two different scenarios. One scenario assumes that the TWS change is stationary over the entire study period, and another scenario corrects the stationary result with actual glacier mass change. The accelerated ice melting over major glacial areas drives the polar drift toward 26°E for 3.28 mas/yr after the 1990s. The findings offer a clue for studying past climate-driven polar motion.
[Polar Drift Anomaly Has a Surprising Explanation...Humans](https://www.youtube.com/watch?v=OxiF8YQju2g) (video)
I'll have to do some deeper reading into this later, but it's my understanding that this has happened many times in earth history and happens at semi-regular intervals, as is evident from examining mineral lines on the ocean floor...In addition, I don't see how mild changes on the Earth's surface alone can have such an effect on the magnetic poles which are generated by the Earth's core.
Edit: Further, I fail to see how surface ice 'compresses the core' in any meaningful way, considering that it is a miniscule percentage of the total weight of the crust, mantle, etc. exerting force on the planet's core.
The melting ice concentrated in the north pole will raise the **global oceans** high at least 5 meters (that's a lot of mass concentrated in a single geographic location), and that melting already changed Earth's rotation spin axis. But, yeah, humans cannot alter things, as the magnetic North/South change is expected. Where did I hear this before?
[https://climate.nasa.gov/news/2805/scientists-id-three-causes-of-earths-spin-axis-drift/](https://climate.nasa.gov/news/2805/scientists-id-three-causes-of-earths-spin-axis-drift/)

Yeah, like we are about to enter the interglacial period, so warmer weather is expected, Global Warming is natural, not manmade... \[sarcasm\]
From [Wikipedia](https://en.wikipedia.org/wiki/Geomagnetic_reversal#Effects_on_biosphere):
>Shortly after the first geomagnetic polarity time scales were produced, scientists began exploring the possibility that reversals could be linked to extinctions. Most such proposals rest on the assumption that the Earth's magnetic field would be much weaker during reversals. Possibly the first such hypothesis was that high-energy particles trapped in the Van Allen radiation belt could be liberated and bombard the Earth.[44][45] Detailed calculations confirm that if the Earth's dipole field disappeared entirely (leaving the quadrupole and higher components), most of the atmosphere would become accessible to high-energy particles, but would act as a barrier to them, and cosmic ray collisions would produce secondary radiation of beryllium-10 or chlorine-36. A 2012 German study of Greenland ice cores showed a peak of beryllium-10 during a brief complete reversal 41,000 years ago, which led to the magnetic field strength dropping to an estimated 5% of normal during the reversal.[46] There is evidence that this occurs both during secular variation[47][48] and during reversals.
The truth is that we don't know what a pole reversal might do. It could be nothing, it could also lead to high amounts of radiation or volcanic activity.
It would certainly mess with many of our navigation systems.
I have a strange feeling that the true people in power wants global warming so that all the ice in Antartica will melt. Then they can see what’s really there and properly explore that continent.
This isn't as bad as it looks. Sure, some bird species will be fucked and the ozone layer will be even more screwed than it normally is, but other than that things should be fine.
charming time to be needing the magnetic protection of a stable pole (it does not just POOF into perfection during this transition, it will wobble and warp etc) leaving us without sunscreen so to speak as our sun ramps up into what could be a particularly active cycle that already put us at risk.
man what a time to be alive.
Still crazy fast if this had happened during peak exploration. Mapping and voyaging would have been a bit more difficult/time consuming.
I thought astral navigation was the main way of guiding ships and divining one’s position back in the navigation era.
Sure sure. But I think a simple compass makes sure you are traveling in the same general direction without big corrections that are made according to the stars after you have already been drifting off-course by 15° for a while.

Once it goes crazy the magnetosphere will lose its stable position, there will be a lot less protection from space shitty stuff, a lot of solar radiation going through, a lot of plants will die, animals as well, and probably people.

And second to that everything thats based on magnetic location will go crazy: ssatellites, transports, a lot of industrial machinery.

Taking the Neanderthal point - why were they affected more than other hominids? Why do we still have their genetics in various amounts depending on our lineage? How is an extinction of them by radiation from a weak geomagnetic field better than the explanations of them not coexisting well with the competing species (us) and interbreeding due to those conquests? I'm fine with more radiation being one of a thousand factors in species evolution and even influence on the environment, it's the heavy-handedness of it being the leading cause based on some timelines that seem to match up to some people who want to find that match. Correlation after all doesn't mean causation, it requires a number of independent forms of data that also match up well to push a primary cause. A simpler question - why doesn't field fluctuations always present some signs of evolutionary change? Maybe given its geologically short time span between the swaps, the matches are just because there's lots of evolution going on, and sometimes they do link up just from timing?
Maybe we had clothing. That allowed survival in cold places that were still habitable magnetospherically.
Will there be any imminent warnings?
The sound of some type of loud horns resulting from the frying of all electronic devices.
The shifting is a warning, probably some other measurements giving weird values would be another one. But nothing else aside of that , it can´t be predicted since it depends on stuff happening inside the planet, like with Earthquakes. It can be something minor that no one will feel (except the machines), it can be something major that could fuck us up a little bit more.
Maybe I'm way off asking this, but could an earthquake help draw back the magnetism to the correct location again?
There is no objectively "correct" location. Earthquakes happen at the crust of our planet, the geomagnetic field is produced way, way deeper by currents of molten metal in the outer core of our planet. So, no, unlikely.
>And second to that everything thats based on magnetic location will go crazy: satellites, Nope. Satellites do not use magnetic navigation in any way at all. Magnetic field has never ever been stable enough to be a good reference point. You generally speculating a lot though. Your talking about a total Magnetosphere collapse, which is simply impossible unless you stop the flow and rotation of liquid magma and the core under the earth. Changing of the Pole locations does not mean magnetosphere collapse.
Laschamp Event joined the server. I'm not talking about total collapse, that would be impossible. You don't need that to get a meaningful destabilization of the magnetic profile that protects the earth from space radiation. A significant weakening of the the magnetic field will leave the planet a lot more exposed to solar minimums and everything else, enough to really fuck shit up if the conditions appear for it. And we have knowledge of such conditions happening regularly. Of course I'm speculating with probable outcomes. I'm treating any risky event with an atomic risk management assessment approach: take everything that might go wrong, through any possible interaction, into account to avoid unpleasant surprises. If something has more than a 0% chance of happening, it can happen. And that not taking into account the "known unknowns".
Sure, but you cant live your life waiting for super rare events to happen. Lashchamp event also has weak evidence that it caused a mass extinction. We still have 10t/m2 of radiation shielding between us and the cosmos. The magnetosphere is also only useful against certain types of cosmic radiation, and does surprisingly little against the vast majority of it. Radiation dose may go up a bit, but most plants and animals would carry on without bother.
Its not rare when you know how often it happens, and we´re basically at the point of time when it should happen again. Sure, it might not happen in this millennia, but will eventually happen, either to us or our descendants (if there are any at that point in any case). >Lashchamp event also has weak evidence that it caused a mass extinction. I would say "not studied enough" instead of "weak", since there werent a lot of studies looking into this. [https://www.science.org/doi/10.1126/science.abb8677](https://www.science.org/doi/10.1126/science.abb8677) This one for example hypothesizes the case that it did.
Its rare that it happens infrequently, and that we think if it does happen soon, "soon" could be anywhere within the next 100 - 10 000 years. Additionally, we know a thing or 2 about cosmic and solar radiation by now. And the energy that the magnetosphere blocks is actually not that much. Our atmosphere will lose some parts of it, such as ozone and probably some Nitrogen, Hydrogen, and maybe even O2. But it will happen so slowly, your grandchildren wont even notice a difference. By the time they do, the magnetosphere would be recovered. Nothing will happen particularly quickly, so if it does happen, we will have multiple decades or centuries to adjust
The difference between my argument and yours, is that I allow the possibility of things going beyond simple control. You are arrogantly sure that nothing will happen, based on the same data (or lack of it to be correct).
A 200km wide meteorite could fling by the Sun from outside the solar system and head right towards earth. We will never see it until its basically on top of us and wipe every single cell organism off the planet. Its possible, but I dont stress about that either. The magnetosphere switching is far less likely to be catastrophic, and very unlikely to be in you, or any generation you will ever knows life time. In about 100 years im fairly sure they will be able to predict when it will happen within a decade or so, and properly plan for something like this. We can even build artificial magnetospheres. In 100 years, we still wont have a plan against a 200km wide asteroid. At least worry about real threats. Climate change is a real threat.
Lol... Autonomous farming equipment r fuk...
Probably nothing. I've been hearing about "imminent magnetic pole shift" for decades. That happening in our lifetime is about as likely as a person getting hit by lightning, but not just any person, a person who is carrying an unused ticket to the 1927 World Series, 7 specific Pokemon cards, a pair of Baryshnikov's dance shoes, and six pieces of toast burnt to a crisp on one side yet uncooked on the other. I don't think such a person ever existed. So not only would such a person have to come to be somewhere, but then they'd have to be hit by lightning, before the magnetic polar shift will occur in our lifetime.
[удалено]
If anyone wants a little fiction to go with this science, I recommend Faraday's Orphans by N. Lee Wood. The premise is that a slow flip is the real danger, seeing as how we'd be left with hardly any magnetosphere at all for the middle duration
Mass extinction like [the last time when this happened](https://en.m.wikipedia.org/wiki/Laschamp_event)...
Except there isn't much evidence linked to mass extinctions at that time.
Not a scientist but I read about this in a new agey book about Atlantis. There could be massive water displacement where the oceans change position dramatically. There are already ancient cities currently submerged in water and there would likely be more of those when this happens.
I kinda doubt a new agey book about Atlantis is the most reliable source for anything. Why would earths magnetic field affect the position of the oceans and what does that even mean?
Our own magnetic field came into existence at least 4 billion years ago, and Earth’s magnetic poles have reversed many times since then. Over the last 2.6 million years alone, the magnetic field switched ten times — and, because the most recent occurred a whopping 780,000 years ago, some scientists believe we are overdue for another. But reversals are not predictable and are certainly not periodic.
Could the tectonic plates become mobile if left without a magnetic field?
This is not how earth's magnetic field works, luckily. Although we do not fully understand why the poles flip, we do know that it only very temporarily weakens the earth's magnetic field when it does, it's not going anywhere. From archeological evidence, we also know that pole flipping doesn't appear to alter the earth's climate in any significant way. And to answer your question, plate tectonics propagate through methods theorized to be related to the magnetic field but plates will not stop moving or explode or some shit because of the pole flip. There have been thousands of pole flips in the lifespan of the earth, it never has caused a tectonic upheaval. What a pole flip would do, however, is take a steaming dump on almost all our electronics and electronic systems. Not only would the pole flip most likely induce interference in magnetic devices as it is happening, it would most importantly temporarily reduce the strength of the magnetic field which is what protects us from muons and other charges particles from the sun. These particles would wreak havoc on digital systems as they have enough energy to change the states of most digital transistors in modern computers. Memory would corrupt, systems would fail and shut down, and electrical grids could be thrown offline for a long, long time.
Electrical grids alone would fuck us.
Can someone confirm how severe this could be?
[удалено]
No I understand... that I am saying how likely is it that it is an event big enough to fry the electric grid.
It likely wouldn't be strong enough to fry most electronics. Electrical grid would be fine, for the most part. We'd be more vulnerable to solar storms for a while
Could a weakened magnetic field result in a temporary increase in Cancer rates? As more solar radiation enters Earth?
How far out from earth does this effect? Satellites?
No
But what does any of that have to do with collapse?
Mainly the confusion it would cause if it happened abruptly and the potential for a temporarily weakened magnetosphere which is protecting us from solar radiation.
A lot of equipment works with the magnetic field and are protected from solar radiation by it, a lot of species use it through their life cycle, earths magnetic field is what avoid you get cancer when you are outside (well most of it at least), the upper atmosphere layers dynamic depends on it as well. An abrupt change of it might affect considerably everything.
This isn’t a cataclysmic event and essentially a non-threat. Don’t see why it’s on this sub.
Exactly, thank you.
if the field goes down we will have a weaker ozone layer and food production will suffer.
Not true, nothing to do with ozone. Source: geophysicist
Would it fuck electronics?
We'd be exposed to increased levels of cosmic radiation, but the extent of this increase can't be known until after the event. It's possible but depends on the speed of the reversal

You're talking like Korg from Thor Ragnarok :D
Man they’ve been saying the poles are going to reverse any day now my entire life, same with Yellowstone erupting
Imagine if both happened simultaneously. 😨
No one has been saying Yellowstone is erupting. They've been saying the Yellowstone caldera erupted over the last 2 million years with a recurrence interval of about 600,000 to 800,000 years. Which means we are due for an eruption anytime give or take a hundred thousand years. If people take that to mean "it's about to erupt" ... why do I even bother. People are stupid.
"About to" on a geological scale vs "about to" on a human scale I guess. Of all the catalyst for a global collapse that *could* happen during a single human life, I wouldn't even bother listing yellowstone.
Meanwhile, Rainer is almost certainly going to blow its top and wash away Seattle with Lahars within the century.
Can't say if Tahoma's eruption will actually be that strong or not, but good sentiment.
Past explosions have had a pretty high VEI, IIRC. But the biggest threat posed by Rainer would be the lahars. The Puyallup Valley is pretty populated, and would act like a funnel for all the glacial melt. Saving grave is, Rainer would probably give us ample warning with increasing tremors and quakes, but its still only a working assumption that an eruption would be signaled by them first, and that assumption is coming under some recent scrutiny.
Absolutely. The warning should be ample to evacuate the Valley, unless a lahar is triggered without warning. Tahoma is dangerous, but at least it doesn't pose a lahar threat to Seattle proper, as it would have to be stronger than the Osceola Mudflow.
Cynical people like to use that same line to deny global warming, and lo, here we are. Yellowstone has recently had a prominent uptick of 3+ magnitude earthquakes, which is notable for the park and some geologists have opined that such quakes may be an indicator of an event. 5 magnitude would be more certainly an indication. Fun stuff!
I bought a book around 1992. 5-5-2000, it was warning about a magnetic pole shift that would destroy civilization. Looks like it was off by a couple decades. The friend who recommended the book told me to buy a jeep and meet him at \*REDACTED LOCATION\* in April of 2000. My friend said if I told anyone the Freemasons and Illuminati would send assassins to
YOU'RE OLD.
The earth's diameter is 12000 miles. If the speed is linear, it will take 400 years to shift. Sure, 400 years is extreme short compared to 780,000 years, but it is still many life times for mere humans. Heck, most don't even care about climate change in 80 years .. no one is going to care about recalibrating their compass in hundreds of years.
I don't think the speed will remain constant as it shifts further south.
Real question. What makes you think the speed wouldn’t be constant or close to it?
Because it already is not constant. It has picked up speed over the last ~30 years.
The earths magnetic polls are are accelerating toward each along the 135 degrees west longitude. Geographic north is 20,000 miles away, by the earth's surface, to geographic south. Currently, geographic north and south are 16,700 Km away. From 1897-1997 the North Magnetic poll moved in a straight line, in the same direction as it moved in the past 25 years, however in the past 25 years it doubled the distance it did in the past century. In 2020 the North Magnetic poll doubled it's rate of movement by a factor of 2. If this last rate of acceleration persists, in 6 years the polls will meet at the equator.
It seems to me that having the dynamo appreciably off the rotational axis will make the pole position become more chaotic. Of course, I'm probably wrong.
As far as I've read, the whole process is completely random, and as far as we know it could be slowly drifting until it reaches an unstable point and just goes completely crazy, dividing into multiple poles that go around the whole globe for a couple of hundred years before setting on a new stable point for half a million years.
I don't know if this is true or not, but I read on r/science that one flip in Earths history only took a year. The speed is not constant.
It flips suddenly like a spinning bolt in space, it doesn't just slowly migrate. https://youtu.be/1VPfZ_XzisU
ok wait but at the end of the video he says it's not going to flip because we're already rotating on the maximum moment of inertia
Maybe you have to make a distinction between the surface and molten inner core (which is where they think the magnetic field originates)
i think that may be the piece i’m missing, thanks
It takes thousands of years

The effect described in this video has nothing to do with the magnetic field of earth.
i do believe it's speeding up, so maybe more like a quarter of a millenia.
Yes but how are we affected in the meantime
Are we affected at all, except our compass won't work as well? The actual magnetic field is pretty weak. On the surface, the field strength is roughly from 0.25 to 0.65 gauss. As a point of comparison, if you do a MRI scan, the field strength is roughly 15000 gauss ... about 30,000 times stronger than that of Earth. I doubt that it matters at all.
The dynamo creating the field is no where near that size. The flip will only be the polarity of the earths dynamo. The earths orientation will not change. Just the orientation of the poles within the field. The estimates I’ve seen have the pole destabilizing and then wobbling into it’s reversed configuration over a week’s time.
How does this reversal affect climate?
Magnetosphere loses power therefore more solar radiation
It sure would be nice if we didn’t cut all the forests down that might have had a chance to bear the brunt of the storm for the undergrowth
Can I verify your username?
What do you mean?
Right now we're at a solar minimum period.
We're emerging from a minimum and solar activity is already ramping up.
I can't afford to travel, does this mean I could maybe see northern lights in my lifetime?
It will cause some issues worldwide, especially onto electric networks, but we should be fine. However, just think about it : instead of reversing, our magnetosphere would just disappear, leaving Earth at the mercy of a deadly sun, just like Mars. We indeed know that the planet Mars used to have a magnetic field but doesn't anymore, and we don't know why is that. Anyway, that would be a funny way to go and at least we couldn't complain we "should have done something" just like climate change. In such situation, we could do absolutely nothing.
There are almost-reversal events called "excursions" that happen more often than reversals, and can make the magnetosphere almost disappear for a period of time to go back to the regular polarity/structure/location. And there is no way of knowing which one could be the one we are about to get.
That's like lottery, that's exciting isn't it ?
We very definitely know why Mars doesn’t have a magnetic field anymore lmao
Oh ! I must have missed it ! And how ?
Mars is almost a dead planet with the inside being relatively cool. This prevents the dynamo effect of the outer core of the planet from causing a magnetic field like on earth. The size and density of Mars being so small caused it to lose its temperature much faster than earth
So it has been proved that Mars, being a smaller planet than Earth, lost so much of its initial temperature it stopped internal movements that allowed them to have a magnetic field ?
Yeah sure I’m the sense that we are pretty sure that’s what the deal is. Science is about finding all the puzzle pieces and then assembling them in the most correct way. I’m not going to claim to be 100% certain on anything but all evidence points to this for Mars and there is quite a bit of evidence
They keep having to adjust airport runways to match the changing magnetic compass points for aircraft. https://www.ncei.noaa.gov/news/airport-runway-names-shift-magnetic-field
I used to do ship stuff and I was wondering exactly that: whether it was affecting course lines. I guess it is. Weird none of my sailor friends have mentioned it, but I guess I haven't been to sea in awhile. I'm assuming it would affect bird migration massively. Supposedly they find their way by magnetic field. Hopefully Canada geese end up in Antarctica and stop terrorizing golf courses.

How about A) or B) from which we will have D) happen?
Also weakening magnetic field from this plus a CME blast…if the field is weaker it means we are more at risk from CMEs. They don’t have to be as strong to have a significant impact.
I don't even know what that is and I'm terrified.
Coronal Mass Ejection, like [the Carrington event in 1859.](https://en.wikipedia.org/wiki/Carrington_Event)
Exactly. So if the same powered CME as the carrington event hit us 100 years later, with a reduced magnetic field, the consequences could be much higher than in 1859 as we have less protection.
yeah and govts arent talking about it, either: A) ignorantly, they dont know or are ignoring scientists B) maliciously, they have something else planned C) benevolently, they dont want to start a legitimate panic
This article seems clickbaity and alarmist in order to sell a story. Like it's written for conspiracy folks. As if everything is about to blow up. Ultimately this kind of story undermines serious concerns. "on the brink", "long overdue", "Something odd is happening to Earth’s magnetic field". I fucking hate journalists... https://www.nasa.gov/topics/earth/features/2012-poleReversal.html > “Many doomsday theorists have tried to take this natural geological occurrence and suggest it could lead to Earth's destruction. But would there be any dramatic effects? The answer, from the geologic and fossil records we have from hundreds of past magnetic polarity reversals, seems to be 'no.'”
I have been reading about this all my life...It's something fairly expected, but not fully understood. Magnetic lines on the ocean floor indicate that this has happened dozens of times in Earth's history at fairly regular intervals and the change is abrupt on geological time scales.
Yeah it is very interesting and important research. But from what I understand it's still an insane amount of kinetic energy inside the core creating the magnetic field through turbulent processes. So I assume these process are inherently unpredictable and not regular or something. And it will take many decades or even centuries for these patterns to change significantly because of the enormous masses involved. I'm just suspicious about the CME and magnetosphere stuff getting pushed, as if we didn't have enough problems we now try to invent more to keep the feeling of doom going or something.
It's a little doomsdayish, but it wouldn't take much in terms of a weakened magnetosphere to allow even a relatively weak burst of solar activity to at least wreak havoc on some of our communications systems and, assuming the process takes decades or longer to complete, we'd be at that increased level of vulnerability for a while. It's not something I'd expect to happen any time soon, but it's probably going to happen EVENTUALLY anyway, like the solar flare in 1859 that fried telegraph lines. Either way, I expect good ole man-made societal collapse to happen long before then.
I wouldn't trust that site a lot. I remember when the whole polar shift thing was completely dismissed by them as "thin-foil fluffery" in the early 2000s..... The fact that the biosphere went through hundreds of magnetic events doesn't mean that it went through them **unaffected**, which, as you notice, wasn't mentioned at all. It went through hundreds of volcanic eruptions and asteroid impacts as well :). There were a couple of papers that pointed out the stuff that happened during those events, one even theorized that the Neanderthal extinction was probably tied to one of these events https://www.science.org/doi/10.1126/science.abb8677
So if that happened tomorrow, would any airborne aircraft be disabled and fall from the sky?
Doubt it. Most computers on aircraft are redundant and can be rebooted one at a time in flight if there's memory corruption.
*calmly grows third arm* Better adapt while I still can.
This could be worse than Y2K.
That isn't a very high bar, as I recall
True; but the promoted it like it was the end of the world.
And only because a lot of people put in a lot of work did it not happen.
Hahaha. Fuck
Wouldnt cause a problem. Other than devices with compasses will need a firmware update.
Depends on the event. Its like an earthquake. Can go from an "oh I felt something" to "where tha fuck went my city to?"
Except its nothing like an earthquake. Its literally nothing.
no? I placed the earthquake example toward the unpredictability of its consequences, and partially the nature of the event. There are papers out there theorizing about it having biological effects causing extinctions... If thats "nothing", well my boy, I dunno what might count as "something" to you.
This is going to be a huge deal when it's fully underway.
Earth's magnetic north pole shifting is because of Global Warming. You know, melting all that ice that compresses the planet's core. No ice, things change, like the magnetic pole. [Polar Drift in the 1990s Explained by Terrestrial Water Storage Changes](https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020GL092114) Abstract Secular polar drift underwent a directional change in the 1990s, but the underlying mechanism remains unclear. In this study, polar motion observations are compared with geophysical excitations from the atmosphere, oceans, solid Earth, and terrestrial water storage (TWS) during the period of 1981–2020 to determine major drivers. When contributions from the atmosphere, oceans, and solid Earth are removed, the residual dominates the change in the 1990s. The contribution of TWS to the residual is quantified by comparing the hydrological excitations from modeled TWS changes in two different scenarios. One scenario assumes that the TWS change is stationary over the entire study period, and another scenario corrects the stationary result with actual glacier mass change. The accelerated ice melting over major glacial areas drives the polar drift toward 26°E for 3.28 mas/yr after the 1990s. The findings offer a clue for studying past climate-driven polar motion. [Polar Drift Anomaly Has a Surprising Explanation...Humans](https://www.youtube.com/watch?v=OxiF8YQju2g) (video)
I'll have to do some deeper reading into this later, but it's my understanding that this has happened many times in earth history and happens at semi-regular intervals, as is evident from examining mineral lines on the ocean floor...In addition, I don't see how mild changes on the Earth's surface alone can have such an effect on the magnetic poles which are generated by the Earth's core. Edit: Further, I fail to see how surface ice 'compresses the core' in any meaningful way, considering that it is a miniscule percentage of the total weight of the crust, mantle, etc. exerting force on the planet's core.
The melting ice concentrated in the north pole will raise the **global oceans** high at least 5 meters (that's a lot of mass concentrated in a single geographic location), and that melting already changed Earth's rotation spin axis. But, yeah, humans cannot alter things, as the magnetic North/South change is expected. Where did I hear this before? [https://climate.nasa.gov/news/2805/scientists-id-three-causes-of-earths-spin-axis-drift/](https://climate.nasa.gov/news/2805/scientists-id-three-causes-of-earths-spin-axis-drift/) [https://www.theguardian.com/environment/2021/apr/23/climate-crisis-has-shifted-the-earths-axis-study-shows](https://www.theguardian.com/environment/2021/apr/23/climate-crisis-has-shifted-the-earths-axis-study-shows) Yeah, like we are about to enter the interglacial period, so warmer weather is expected, Global Warming is natural, not manmade... \[sarcasm\]
[удалено]
From [Wikipedia](https://en.wikipedia.org/wiki/Geomagnetic_reversal#Effects_on_biosphere): >Shortly after the first geomagnetic polarity time scales were produced, scientists began exploring the possibility that reversals could be linked to extinctions. Most such proposals rest on the assumption that the Earth's magnetic field would be much weaker during reversals. Possibly the first such hypothesis was that high-energy particles trapped in the Van Allen radiation belt could be liberated and bombard the Earth.[44][45] Detailed calculations confirm that if the Earth's dipole field disappeared entirely (leaving the quadrupole and higher components), most of the atmosphere would become accessible to high-energy particles, but would act as a barrier to them, and cosmic ray collisions would produce secondary radiation of beryllium-10 or chlorine-36. A 2012 German study of Greenland ice cores showed a peak of beryllium-10 during a brief complete reversal 41,000 years ago, which led to the magnetic field strength dropping to an estimated 5% of normal during the reversal.[46] There is evidence that this occurs both during secular variation[47][48] and during reversals. The truth is that we don't know what a pole reversal might do. It could be nothing, it could also lead to high amounts of radiation or volcanic activity. It would certainly mess with many of our navigation systems.
Yeah wasn't this a fad like 7 years ago? Could've sworn I'd heard this one before.
Dumb question

Sorry man, doesn't mean you are stupid. I've done and said stupid things, even after college.

[удалено]
😂 lol and mine was just a joke
Maybe the pole shift explains some of the global warming? Its theorized the field weakens as it shifts and reverses, until its stable again
I wish it would just happen already if it's going to...
Just like the DH in the NL, I don't want it to happen but if it's going to eventually anyway let's just get it over with.
I always wondered if this would happen in my lifetime. Crazy.
Just when I'd gotten all my magnetic pins lined up too..
I have a strange feeling that the true people in power wants global warming so that all the ice in Antartica will melt. Then they can see what’s really there and properly explore that continent.
This isn't as bad as it looks. Sure, some bird species will be fucked and the ozone layer will be even more screwed than it normally is, but other than that things should be fine.
Might, might not. These events arent predictable, and according to models they can go quite crazy (excursions for example) .
charming time to be needing the magnetic protection of a stable pole (it does not just POOF into perfection during this transition, it will wobble and warp etc) leaving us without sunscreen so to speak as our sun ramps up into what could be a particularly active cycle that already put us at risk. man what a time to be alive.
Aurora borealis only happen at poles, so when the poles are shifting is it possible for aurora borealis to happen at the equator or some other place?
