Earth’s magnetic field is acting up and geologists don’t know why
Nature ^ | 09 January 2019 | Alexandra Witze

The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.

On 15 January, they are set to update the World Magnetic Model, which describes the planet’s magnetic field and underlies all modern navigation, from the systems that steer ships at sea to Google Maps on smartphones.

The most recent version of the model came out in 2015 and was supposed to last until 2020 — but the magnetic field is changing so rapidly that researchers have to fix the model now.

The problem lies partly with the moving pole and partly with other shifts deep within the planet. Liquid churning in Earth’s core generates most of the magnetic field, which varies over time as the deep flows change. In 2016, for instance, part of the magnetic field temporarily accelerated deep under northern South America and the eastern Pacific Ocean.

“What’s happening?”

First, that 2016 geomagnetic pulse beneath South America came at the worst possible time, just after the 2015 update to the World Magnetic Model. This meant that the magnetic field had lurched just after the latest update, in ways that planners had not anticipated.

Second, the motion of the north magnetic pole made the problem worse. The pole wanders in unpredictable ways that have fascinated explorers and scientists since James Clark Ross first measured it in 1831 in the Canadian Arctic. In the mid-1990s it picked up speed, from around 15 kilometres per year to around 55 kilometres per year. By 2001, it had entered the Arctic Ocean — where, in 2007, a team including Chulliat landed an aeroplane on the sea ice in an attempt to locate the pole.

In 2018, the pole crossed the International Date Line into the Eastern Hemisphere. It is currently making abeeline for Siberia.

Just HOW is the postman going to get my letter to Santa if he keeps moving? I’m really getting sick of not getting my pony. I’ll give him one more chance and then I’ll show him naughty.

Earth has been through numerous magnetic polarity reversals. I hope that is not what is going on right now.

The geologic record shows that the poles periodically ‘flip’ over a period of time. Appears to be happening again.

This could be a sign that the poles are going to switch in the next 100 years or sooner. This apparently happens every few hundred thousand years or so. It could cause some issues worse than just our compasses being screwed up for up to a couple hundred years.

Shouldnt it be called the MM pole?...for magnetic moment...or moving magnetic....will all magnetic compasses be autocorrect type? Either ways its all the deplorables fault.

"Whatever the actual explanation is, it’s Trump’s fault."

It's all that steel fencing he wants to put on the border.

"...but I’m surprised. In my youth it was in central Canada. Now near Siberia? That’s a big move!"

Maybe it got tired of Justin Trudeau, and decided to leave.

It is because Nancy Pelosi was anointed Speaker of House.

If it didn’t bother the dinosaurs, why should it bother us?

The Russians did it!

Special counsel Mueller needs to investigate this conspiracy immediately!

Rotate iron inside a magnetic field to generate electricity.

Run electricity around an iron core to generate a magnetic field.

pehaps that large ball of iron rotating and moving through the sun's fields creates our magnetic field, and the poles of it.

The earth is rotaing and moving through the sun's field continuously, and the sun's field may change, depending on who knows what, thus the earth's fields are affected.

My story and i;s sticking to it. :-)

Maybe the magnetic field is just so happy Donald Trump is president that it just can’t contain itself.

Whatever happens it can’t be as bad as Enya charting in Billboards top 10.

I have been moving the north pole around with the magnet I installed on my last trip up north.

Remember the good ole days when everything was Bush’s fault and everybody loved Donald Trump?
