Default Magnetic North on the move ...

Interesting article .....

https://www.foxnews.com/science/some...-one-knows-whyPlanet Earth is alive. Deep beneath its skin, its life blood — rivers of molten iron — pulse around its core. And this mobile iron is what generates the magnetic field that causes auroras — and keeps us alive.But, according to the science journal Nature, something strange is going on deep down below.It’s causing the magnetic North Pole to ‘skitter’ away from Canada, towards Siberia.

“The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move,” Nature reports.On January 30 (delayed due to the US Government shutdown), the World Magnetic Model — which governs modern navigation systems — is due to undergo an urgent update.This model is a vital component of systems ranging from geopositioning systems used to navigate ships through to smartphone trackers and maps.The current model was expected to be valid until 2020. But the magnetic pole began to shift so quickly, it was realized in 2018 that the model had to be fixed — now.“They realized that it was so inaccurate that it was about to exceed the acceptable (safe) limit for navigational errors,” Nature reports.FICKLE TIDESEvery year, geophysicists from the US National Oceanic and Atmospheric Administration (NOAA) and the British Geological Survey do a check on how the Earth’s magnetic field is varying.This is necessary as the liquid iron churning in the Earth’s core does not move in a consistent manner.“In 2016, for instance, part of the magnetic field temporarily accelerated deep under northern South America and the eastern Pacific Ocean,” Nature reports.This shift was captured by satellites.But the movement of the north magnetic pole has been the object of study since 1831. Initially, it was tracked moving into the Arctic Ocean at a rate of about 15km each year. But, since the mid 1990s, it has picked up speed.It’s now shifting at a rate of about 55km a year.

But another recent study has revealed the Earth’s magnetic field has been acting up now for some 1,000 years.

CORE OF THE MATTER

Why the magnetic field is shifting so dramatically is unknown.“Geomagnetic pulses, like the one that happened in 2016, might be traced back to ‘hydromagnetic’ waves arising from deep in the core,” Nature reports. “And the fast motion of the north magnetic pole could be linked to a high-speed jet of liquid iron beneath Canada”.This fast-flowing molten river appears to be weakening the magnetic influence of the iron core beneath North America.“The location of the north magnetic pole appears to be governed by two large-scale patches of magnetic field, one beneath Canada and one beneath Siberia,” Phil Livermore of the University of Leeds told an American Geophysical Union meeting. “The Siberian patch is winning the competition.”And, as global warming opens up more shipping lanes to the north of Russia and Canada, this presents a potentially deadly problem.“The fact that the pole is going fast makes this region more prone to large errors,” says Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and NOAA.

Big Eruption coming?

The global warming fanatics are going to have a melt down (no pun intended) because this explains why the Arctic ice caps are declining.

I understand that the magnetic poles actually flip once every 200,000-5 million years and its not a gradual thing. I wonder if my Nav warranty is going to cover this.

Well duhhhh - it's been on the move ever since it was discovered. No, that's not right - it's been on the move since before it was discovered.

Yup saw a story about this several years ago and they predict an outright flip at some point in the near (historically near) future.

I think Putin and Russia must have fired up a big magnet over there to pull the pole over their way. It's a control thing. Trying to get it done before next Christmas so Santa is a little closer to their little folks.

Seriously though... makes you wonder if shifting molten iron in the earth would have other complications... like earthquakes or volcanoes which would be a bit more concerning than having to recalculate magnetic variation or deviation.

I saw this today too.
BIG difference in 15KM/year versus 55KM/year from a navigational standpoint.

Those damn Russians are at it again.

First they steal an election, now they are stealing the North Pole. When will they be put back in their place?

Does this explain why my plotter has gradually shown my boat closer and closer to dry land when Im at the dock? It now shows my boat in the middle of the road.

Sea level has been rising for centuries, magnetic north has been moving for centuries, CO2 levels have been rising for centuries, sky hasn't fallen yet....

Airports are going to be busy painting new runway numbers.

if everything is melting why isn't the water level at my dock rising?

" So what happens if you don’t bother changing the runway designations because it’s such a headache to repaint everything, change every sign, edit all the documents, and find the money to do it? “The big-picture answer is probably nothing,” says John H. Mott "

Well, at least we don't have folks running around saying they have to pour new concrete so the runway still lines up with the old heading!!!

We NEED Al Gore to get on this right away.

This is MY argument also. South Florida? It's all built on mangroves..I'll bet they are sinking...the water level is NOT rising.
