Earlier this year, US National Oceanic and Atmospheric Administration and the British Geological Survey (BGS) were forced to update the World Magnetic Model a year ahead of schedule due to the speed with which the magnetic north pole is shifting out of the Canadian Arctic and toward Russia’s Siberia.
The BGS and the US National Centers for Environmental Information has released a new update to the World Magnetic Model this week, confirming that the magnetic north pole, whose coordinates are crucial for the navigation systems used by governments, militaries and a slew of civilian applications, is continuing its push toward Siberia.
“The WMM2020 forecasts that the northern magnetic pole will continue drifting toward Russia, although at a slowly decreasing speed –down to about 40 km per year compared to the average speed of 55 km over the past twenty years,” the US agency said in a press statement.
The data confirmed that this year, the magnetic north pole passed to within 390 km of the geographic North Pole, and crossed the Greenwich (prime) meridian. Compilers also confirmed that the Earth’s magnetic field is continuing to weaken, at a rate of about 5 percent every 100 years.

The World Magnetic Model is used by everything from smartphone compass apps, maps and GPS services to telecommunications transmission systems, and navigation tools for various agencies, including the Federal Aviation Administration, NASA, the US Defence Department and NATO. Scientists Still Don’t Know Exactly What’s Driving Pole’s Accelerated Drift
Magnetic north, the point on the planet’s surface toward which your conventional compass points, is created by the churning of molten metal in Earth’s core, which creates huge electrical currents to produce the magnetic field.
Commenting on the freshly-released magnetic north pole data, Dr. Ciaran Beggan, a geophysicist and geomagnetic specialist from the British Geological Survey’s Edinburgh office, told FT that although the movement of the pole has been “much faster” since the 1990s “than at any time for at least four centuries,” scientists “really don’t know much about the changes in the core that’s driving it.”
With the pole passing the Greenwich meridian and continuing its race east, humanity is entering the unknown, scientifically speaking, since, from the time records of the magnetic north pole’s position have been kept starting in the 16th century, the pole had drifted around the Canadian Arctic.

Dr. Phil Livermore of Leeds University’s Institute of Geophysics recently postulated that a ‘jet stream’ of liquid iron flowing in the planet’s core could help explain shifts in the position of magnetic north, but suggested tracking the flows of this liquid iron could be difficult, “because it lies beneath 3,000 kilometres of rock.”
Scientists have previously expressed concerns about the fluctuations in the magnetic north pole and its possible impact on the magnetic field protecting Earth. Without the field, Earth would be left vulnerable to solar flares, which could cause damage to everything from spacecraft to power grids. Even with the magnetic field intact, the planet remains vulnerable. In 2011, the US National Academy of Sciences calculated that a repeat of a solar storm like the one which hit the planet in 1859 could cause as much as $2 trillion in initial damage, and take a decade to repair.
Furthermore, a weakened magnetic field may lead to a potentially cataclysmic process scientists call a “geomagnetic reversal,” in which the Earth’s north and south poles effectively switch places. The last such flip is estimated to have taken place about 800,000 years ago, and some scientists believe that another may be due soon, even though such an event could take centuries to complete.
The Bible says the earth is going to be destroyed by fire. But first, a lot of stuff needs to happen, and then we get 1000 years of reigning on earth with Him.
Ha! I just watched that movie two nights ago.
"Gee, I wish we had one of those North Pole things, Staines."
When the poles flip, nothing will happen except that the arrows on compasses will point the wrong way. Since hardly anyone uses those, nothing important will happen.
Not much. Compasses will point the wrong way. Birds will take a few days to adjust.
Lines.
Crustal displacement
If you never visited the equator, you may get the chance
Fringe theory...never mind
Now, about those wooly mammoths that froze solid while grazing...
It's going to be an incredible sight!
The toilets will flush the wrong way...
So what are the climate screwballs gonna do about this?
That is a awesome graphic! Is there more?
I did not realize that. To which side must we stand?
There was a tourist flight from Warsaw passing the Statue of Liberty on approach to JFK … pilot announced “Out the right windows, you can see the Statue of Liberty” … and the aircraft crashed.
Why?
Russia, Russia, Russia !
So what’s the cause, climate change, the Russians or Trump?
Viewed from either above or below. I dont know for sure.
Now that is a great illustration, thanks!
Its that pesky CO2 Pollution and refusal of Trump to support the Paris accords.
It’s viewed from above. Moon is moving counterclockwise relative to earth, which agrees with moon moving slightly east in the sky each day and thus rising later each day.
Neat graphic.
