North Magnetic Pole Moving East Due To Core Flux
National Geographic is reporting that the migration of Earth's magnetic pole has accelerated again and is now racing in Russia's direction at a blazing 40 miles per year. This movement began in earnest around 1904 at about 9 miles per year and has been accelerating since. "Geologists think Earth has a magnetic field because the core is made up of a solid iron center surrounded by rapidly spinning liquid rock. This creates a 'dynamo' that drives our magnetic field. Scientists had long suspected that, since the molten core is constantly moving, changes in its magnetism might be affecting the surface location of magnetic north. Although the new research seems to back up this idea, Chulliat is not ready to say whether magnetic north will eventually cross into Russia. 'It's too difficult to forecast,' Chulliat said. Also, nobody knows when another change in the core might pop up elsewhere, sending magnetic north wandering in a new direction."
...magnetic north will eventually cross into Russia
Well everything is backwards in Soviet Russia. It was only a matter of time before magnetic North pointed South.
In Soviet Russia North Pole comes to YOU!
God, schmod. I want my monkey man!
Yet another impact of "global warming". Heating the globe is melting the no-longer-solid iron center. Yikes.

I remember reading/hearing in geology (or astronomy? whatever) class that every so-many-thousands of years, the magnetic poles just switch.
If i'm not just making that up, then this is the first articles of many we'll see...
This sig contains repetition and redundancy.
It is actually pretty cool that this happens at the time our technology is so advanced that we can have electronic compasses that simply use GPS to figure out where they are so they can point to the geographic north pole, instead of towards the magnetic one. Imagine how inconvenient it would have been for people if this had happened a view hundred years earlier; they would have to do some extra calculations to navigate their ships.
Yay for technology!
Russia is not that bad they just lunched D-12!!
this comes out to be 4.81872031 inches per minute.
This article covers it...

I've heard it from several sources though, they have geological proof that the earths magnetic field has been periodically flipping and reversing its polarity, and that it does this at periodic intervals, and that we are in fact due for a flip any millenia now.
This explains why paper notes I've left on my fridge with magnets keep sliding down. So in this conspiracy, the magnetic reversal is the blame of either the Russians or the makers of sticky note paper.
So it's NOT 40 miles, it's 64 km.
64 km / 365.25 days = 175.2224503764545 meters per day, 7.300935432352271 meters per hour, 12.16822572058712 cm per minute, 20.28037620097853 mm per second.
That's 2.3 centimeters per second. Forget global warming, it's the Earth axis that's moving and screwing everything. On Christmas day, snow was fucking MELTING over here and we're way up north. Melting snow used to be for the beginning of march.
2012. Galaxy/universe pole shift. It's happening, wether we understand it or not.
Alright, who fired D.E.S.T.I.N.I.?
[End Of Line]
As a Canadian, I feel there's only one rational response to the Russians taking our magnetic north pole (which is sort of owned by the whole of humanity and indeed the planet itself, but has been held in our trust for some time).
All out nuclear war.
And the only downside is nuclear winter! Winter! We can handle a few more months of that each year, easy. It's win-win, really!
Please help this simpleton to understand.
North pole shifts towards Russia, how about the South pole?
It takes two to tango, right?
So, does the South pole shift as well? To where?
A sincere thank from this simpleton for anyone who can help out !

Don't be ridiculous. We have humans now on the planet, AND the magnetic core is shifting. Coincidence? I think not.
If we plot C02 emissions alongside the rate of change of the magnetic north pole, even a 5th grade could see they're correlated.
Humans are to blame for magnetic drift.
QED.
As a Canadian I hope we do not lose the national treasure of having the Pole anytime soon!
Shh.
We cannot allow a magnetic pole gap!
TFA is only about north. South is moving also, but not nearly as much. Two magnetic poles are not a rigid dipole. Maybe in the core, but at the surface they're fairly independent. Given this, it's quite possible that past geomagnetic events were not 'reversals' with north and south sliding past each other and popping out the other side. Rather north and south might wander far enough out of opposite that the Earth's external magnetic field is far off center, and/or very strong over some parts but weak over others. Conceivably they could 'collapse' by becoming too close. The magnetic field would appear to go away although the generator (and whatever drives it) is still operating. I think this makes more sense than the direct reversal in that it assumes the generator to stop operating, which I find unlikely, and start again of its own accord, which smacks of a planetary "and then a miracle occurs". The data does support this hypothesis as being at lest possible. In 2005 magnetic north of 500 miles from true north, while magnetic south was 1750 miles from true south. Either the dipole is off center, which contradicts the generator idea, or the dipole is bent.

Global warming!! After all, it explains everything else...
Like a flux capacitor? Global warming? We're all doomed!
It's a usrr supper weapon
So it's moving east from north. Correct me if I'm wrong, but that's not a useful trajectory as its considered he point from which our basis of geographic location is based - the north pole. So where is it heading?
And, importantly to me and mine, where will that put the north pole in 40, 50 years at the current rate of acceleration? Could this sort of be like the 'wobble' of a top before it falls (meaning we're due for a sudden shift, soon)?
40 miles per year is incredibly fast, especially since it's apparently speeding up. I've read that significant pole shifts have occurred in the past (in 50k year increments, IIRC), and that currently, we're some time overdue for the next.
I've also read postulations that glaciers were not caused by 'ice ages' per se, so much as they were the remains of the north pole ice cap after a shift. I can't find the link right now to the information I found truly interesting (correlation of past poles with existing glaciers) but there's a fair amount of info out there about it. (Some people are correlating it with 2012/doomsday, so be forewarned.)
It's a particularly interesting topic if you look at the archaeological records of our past; specifically, the polar relation/geographic locations of Egyptian, Mayan, and other ancient peoples' religious/whatever sites. They seem to predict a pole shift, or at least make subtle suggestion to one occurring in the past.

40 miles per year? That's a speed, not an acceleration.

You are entitled to your own opinions, not your own facts.
First the Russians tried to claim most of the North Pole by saying it was in their territorial waters. Soon, they're gonna try claiming the magnetic North Pole too.

Without a magnetic field to stop the solar wind, satellites tend to die.
Granted, GPS is military and not LEO, so it might be built a bit better than most.
magnetic north pointed north!
Don't bother trying to explain the facts to this asshat and his illiterate moderator. This is Slashdot. People rarely pull their head from their ass long enough to learn something. They all think they're too smart for that nonsense.
Yeah, been saying this for a year + now. There is an intruder in the Solar system that NASA is not talking about (and why would they?) causing this magnetic influence. This, and many more global dots need to be connected to understand the very broad implications this has on Earth. The intruder happens to be a highly magnetic planetary SYSTEM that has been causing the accelerated global changes to the weather and sea level that will lead to a massive global catastrophe. blackcrow.
I really can't tell whether you're kidding or not.
the real question is when will they start blaming this shift on the american public?
Ahh ok, that does explain alot.
You are entitled to your own opinions, not your own facts.
I am absolutely serious, you need to know that. I have a great deal of information on this as it is my all-consuming activity now, between my 2 businesses, singing a new girlfriend. Blackcrow.

First of all, allow me to commend you for the perfect analogy — laws are programs, and law-making is programming... Now, to answer your questions...
Linux kernel is reviewed by thousands of people back and forth all the time. There are automatic tools verifying syntactic and even (rudimentary) semantic correctness. Thousands of "tinderboxes" test any changes for hours every days and report any deviations. The history of changes (diffs) is publicly available at all times, studied and discussed by even more people.
The two thousands pages of the bill in question has never been read in full by a single person — and when such a feat was undertaken, by the time the hero finished, the bill was already amended to bribe another Senator, etc. No automatic verification tools exist, of course — even a spell-checker would break. The entire country will be the tinderbox — production testing the below alpha-quality software. Oh, and the earlier prototypes (State-wide programs) have been failures...
And you object to somebody rejecting that software because it is too complex? What happened to coding guidelines, with each function and non-trivial block being carefully commented?
The metric is very simple — if I can't finish reading (and understanding!) it without somebody "committing" a significant change somewhere, it is too long... The "Senate version" was moved to vote after an all-nigher in the Speaker's office, for crying out loud. All those fancy promises (by the most technically advanced Administration, like, ever, dude) of legislation being posted online for days prior to vote have turned into lies. Unreadable, spaghetti-like code, no testing, and not even code review. Who could possibly object?
In Soviet Washington the swamp drains you.
The GPS receiver can also calculate heading based on the Doppler velocities (again, assuming that the GPS receiver is moving). This is how many commercial GPS receivers calculate speed (rather than using position differentials, which are noiser over the short term).
Yes. The personal is political.
Or did you miss that mantra of The Left from the 70s?
That was when The Left gave up being centrist and became openly totalitarian (i.e. their ideology must be ingrated into the total of human activities).
Probably off conspiring again with the global scientist supermafia you guys uncovered, remember?
one thing i've noticed is once a society gets organized it doesn't take long for tech to go exponential. I wouldn't be surprised if the timeline of pole flips of the past matched up with times when dinosaurs or whatever reached a point where they had superconductors and whatnot and as a side effect messed with the earth's dynamo.
Uh oh...

IIRCC the magnetic poles of the Earth are sort of "weak spots" in the magnetosphere's protection against cosmic rays and charged particles from the sun, evidenced by the Auroras. If the pole moved over Russia won't that cause possible radiation/EMI issues?
"Geologists think Earth has a magnetic field because the core is made up of a solid iron center surrounded by rapidly spinning liquid rock...
Last I knew, the Earth's core was made up of two parts, solid iron surrounded by liquid iron and sulphur, and the spinning outer iron & sulphur core is what generates the Earth's magnetic field, not rock.
Impetuous! Homeric!
The largest body of evidence for this is found in the striping of the ocean's floor. In the areas where rock material moves up from the mantle and solidifies, the molten rock aligns with the current magnetic field before it cools, and this alignment cannot be changed once the rock becomes solid. The entire ocean floor is banded with a north/south/north/south alignment pattern, implying the reversal is very consistent from a cosmological timescale perspective.
This reversal of the field occurs approximately every 800000 years, with a period of 1000-2000 years around the switch where the magnetic field is disorganized and significantly weaker than normal. This period has very big implications for lifeforms on Earth... obviously not enough to totally end life, but enough to kill lots of animals from various causes (extra solar radiation, messed up internal compass, disrupted migration patterns,etc.).

Absolutely no need to say what the parent said... anybody can differentiate between velocity and acceleration.
I guess some people can't be helped. :-(
40 miles per year is like 12 cm per minute--you could actually watch it go!
Insightful? Why hasn't this whole thread been modded off-topic? What I see here is a political discussion, nothing about the movement of the magnetic pole due to core flux....
A house divided against itself cannot stand.
In other news, the geographic north is moving eastwards relative to the magnetic north pole. Also, the magnetic south pole is moving eastwards. The geographic south pole is ALSO moving eastwards. Don't you just love spherical geometry?
When you are at the North Pole, no matter what direction you go, you are heading South.
GPS will not show your heading if you are in an airplane. Heading while flying is the direction the nose of the aircraft is pointing while track is the direction the airplane is moving across the ground. GPS without a compass will give you your track along the ground but not your heading if you are flying. This is of course due to the airplane moving through a fluid(air) that is always moving relative to the ground.
Vagueness in law is a feature.
Laws are as specific as the Congress cares to make them. While we think a lack of precision in law is a fault, sometimes they are buggy by design. Many a times, Congress will write something that is intentionally vague, hoping the courts will either sort it out, or go the right way, or essentially make new law as circumstances merit.
As much as we talk about Congress not doing what we want, they know exactly what we want, how we vote, how we feel about issues, etc. The disconnect is that you, me, or other people, all totally do not at all understand what the country as a whole wants, and that is something both political parties are extremely familiar with. They are politicians and they are good at what they do.
In short, we're not going to get better, more civic minded government, until we get better ourselves. I mean, come on, who wants to hear the truth that taxes need to go up and entitlements need to be capped to balance the budget in a meaningful way. WE've known this for 30 years, yet, the voters really do prefer, to buy all this stuff and not pay for it, so what do the pols do? Borrow it.

China independently discovered the compass over a millennia ago. It is literally called the "south pointing device". There was a 50-50 chance of wither direction. Europeans proabbly wanted someting to supplement the North Star when you couldnt see it. In China compasses were used for landscaping, i.e. geomancy. South-facing orientations are more important than north in that craft. Thats probably why the traditional compass points south.
Its only happened once so far - a large storm killed one of two satellites used for pagers in 1994. Since then ground-based cellphones have pretty much replaced pagers.
In 1989 a large solar storm shut down the east Canadian power grid.
In 1859 a monster solar storm knocked out the telegraph system. You could see the aurora all the way to the equator. This storm would probably frymost current satellites and the world's power lines.
The force of the earth's magnetic is enough to convect outer liquid core a few meters every day. Over the course of time this adds up to an extra core rotation in several centuries. This effect was predicted in a long term computer simulation of the earths magnetic field by a Harvard physicist. It was confirmed by Columbia University seismologists who measured seismic velocities anomalies in the earth's core have moved several degrees in three decades of good data, pointing to core super-rotation.
This is not the sudden "earth tipover" anticipated by apocalyptists. But it is an amazing rapid event in geologic time scales.

If the core is a dynamo, why can't we pull current from the core ? If there is a MAGNETIC FIELD produced by the core there MUST BE an ELECTRIC CURRENT ALSO. Could this solve our power needs FOREVER ?

I'm sure putting dad or grandma down at the first sign of trouble with a $70 shot of pentobarbital would save a ton of money. We could also keep recovering patients in 4x4 stainless steel cages instead of those posh heated hospital rooms. Eliminating medical tort would also save a few pennies on the dollar too.

Ok...
First, we can't get electric current from a constant magnetic field, only from the changes. Earth's magnetic field doesn't change fast, in fact, somebody already posted the figure of 19cm each minute, over some 64000km* radius that is quite a low frequency. Then, Earth's magnetic field is quite weak to begin with. Even if it was rotating at a hight frequency, it wouldn't carry a lot of energy.
Now, you are right that the field comes from an electric current. It is a strong current, but it flows in a huge amount of conductor so is very weak at any reasonable volume of Earth's core you choose. Anyway, to directly gather that current (without induction), one'd need to probe the Earth's core (on at least two places), what is quite a task.
* At that latitude, it is less than 64000km. I didn't make the calculations, but it is less than 1 turn every year. That is already too low on any practical sense.

No reason at all. Just have to burrow down a few thousand miles and hook up to a few million cubic miles of liquid iron. I suggest that you get right on it.
Warning: this article may contain humor, sarcasm, parody, and perhaps even irony. Read at your own risk.
So how about gathering the current via induction ? Isn't induction the basis of wi-tricity ?
The problems with induction are on the first paragraph.
