Earth’s magnetic field is acting up and geologists don’t know why

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.

Did you read that yet? Fantastic references and citations.

Yes, about 90% through. It's not as detailed as many things I've read but I like it's condensed format.

Now let me share that I am a theologian and the bible references at the end never clicked and made much real sense until I read this. But as a scientist it all makes sense and I really do think we make a “physical” pole shift on a regular cycle..

Check it out...

I'm actually a pastor. They don't make much sense in some areas but in other areas especially considering the "without form and void" reference it's pretty accurate. Those hebrews words translated "form and void" in Gen verse 2 can mean in essence devastated and ruined. The same terminology is used in Jeremiah 4:23 to describe a devastated earth.

So yeah, I think the bible is describing some type of cataclysms in Genesis 1:1... even if not necessarily a crustal displacement... and then how God brings it back for a "recreation" as well.

Anymore I think it is a great historical record in a metaphorical way. I stopped taking it verbatim many many years ago. But I think it has some very important records of places and events that were natural but attributed differently. :)

Back in my Radar days
we were at 0-13. Where are we now?
