Earth's Magnetic North Pole Officially Has A New Position

Hping to keep tabs on the magnetic north's wandering ways, the World Magnetic Model 2025 has been released this week, revealing the latest official predicted placement of Earth's magnetic fields. This version will remain valid until late 2029, during which time we can expect to see the magnetic north pole slowly edge further toward Russia.

The new version is of timely importance too as the magnetic north pole’s movement seems to be accelerating.

Since the 1830s, the north magnetic pole of Earth has relocated some 2,250 kilometers (1,400 miles) across the upper stretches of the Northern Hemisphere from Canada towards Siberia. Between 1990 and 2005, the rate of pole movement increased from less than 15 kilometers (9.3 miles) per year to around 50 to 60 kilometers (31 to 37 miles) per year.

“The current behaviour of magnetic north is something that we have never observed before. Magnetic north has been moving slowly around Canada since the 1500s but, in the past 20 years, it accelerated towards Siberia, increasing in speed every year until about five years ago, when it suddenly decelerated from 50 to 35 km per year, which is the biggest deceleration in speed we’ve ever seen,” added Dr Brown.

This whole wandering pole business ... I’m having Nunavut!

Looks like it’s getting right with “the Science”....

Well Done, Erf!

Airport runways are designated with the magnetic direction on the threshold. The movement has been significant enough to require updating and repainting the correct magnetic orientation on a few runways.

[Myrddin]

But seriously I do get concerned in the event the poles flip, wondering what that will do to our navigation equipment.

There is a periodic 90 degree rotation that occurs. It is transient and the earth rotates back to the current configuration. The 90 degree flip will put SE Idaho just south of the equator. I wouldn't be real concerned about navigation equipment after the pole flip. Survivors will need some time to figure out the axis of the rotation and where everything ends up.

You can find out more about the flip on the Suspicious 0bservers site. Ben Davidson has lots of documentation.

[metmom]

And so what’s the significance of this for us, aside from navigation issues?

[Deaf Smith]

>>It moves always.

I always considered the relationship of Earth's outer crust, mantle and inner core as a big torque converter which powers the tectonic plates movement.

That the inner core due to imperfections of balance is free to move as it finds its axis as the Earth rotates.

[Paladin2]

I like to drive vehicles with a mechanical Clutch.

No Torque Converters here.

YMMV.

[Thanks for the Post.]

“...having Nunavut!...”

[LOL]

I used to want to go there, but having been to similar places and getting older, I’ll now pass to hang out with the young grand-kids.

[nicepaco]

Boy that is really hauling some asses!
According to my edge of the envelope calculation it has moved 500 NM in 20 years. It would be ok with me if it stayed close to True North for a while.

[sasquatch]

Looks like 5 deg near Monterey Ca since 1955.

Mrs Clause needed a change of scenery.

“1850 corresponds to the alleged beginning of global warming.”

I want to hear the climate change nuts explain how the climate on the surface affects the magnetic field. It’s gon’ be good.

[Peter ODonnell]

You’ll notice that the northward component was less than the westward vector from 1990 to 2010 and is now becoming a slight southerly component again. The North magnetic pole will likely end up near the arctic coast of Russia by 2040-2050.

The positions shown before 1840 are speculative because it was not firmly established where the pole was located before the Ross expedition located it in arctic Canada. The earlier positions are extrapolations of compass readings preserved from earlier decades and centuries. There is probably a considerable margin of error in those positions, the later ones were tracked with great precision as the magnetic pole drifted through Canada’s arctic islands.

I do wonder if there is a correlation with global climate as the temperature trend at most n.h. weather stations is well correlated with the latitude of the pole, and of course, that latitude cannot increase now (especially if a w.s.w. drift begins). It may play out as a sharp cooling trend in European Russia and Scandinavia over next 2-3 decades and an end to the warming trend in N America since we aren’t going to see any further warming influence as the pole retreats west.

[maddog55]

It changes constantly and always has.

[Lonesome in Massachussets]

And so what’s the significance of this for us, aside from navigation issues?

The earth's magnetic poles flip once in a while, like every few million years. Looks like they will again in the near future. During the transition, we get less protection from solar radiation, and cancer rates rise very slightly. The earth's atmosphere will "boil off" more quickly than it currently is, but on human timescales, not significantly. No significant changes in your lifetime.

CNN anchors, on the off chance that CNN survives another 50 years, will claim it as a catastrophe, and shout, "WE'RE ALL GONNA DIE." IOW, nothing significant.

Almost no one depends on magnetic navigation anymore. The practical impact is more a scientific curiosity than anything else.
