Earthís magnetic field is acting up and geologists donít 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.

I just hope that GPS is not a hoax.

It's fascinating. The magnetic pole shifts have been continual throughout geologic time. When I was a kid, I remember a kid's news story (probably in "Weekly Reader") about the "fossil north pole" having been found in Arabia somewhere. So, wth, Pole Shift, aiiieee! Thanks BenLurkin.

It’s made sudden switches, positive north to negative south, and vice versa, many time in geologic history. I learned this back in the 70’s. The level of profound ignorance displayed in today’s media (or more likely intentional panic mongering) and among even the “scientific” press is truly astounding and depressing.

So let me get this straight. Scientists recognize the shifts in the magnetic poles of a dynamic planet but don’t recognize the dynamic shifts in earth’s weather patterns, insisting that any shifts in averages of temperature, rainfall etc. are obviously due to man’s impact and dire changes are necessary.

Give 'em time, they haven't dumbed down the population enough to advance the claim that there's a connection between AGW and pole shift.

Catastrophic Global Magnetic Field Change.

You are SO FAR behind. That was what the called it yesterday. Today it's known as Catastrophic Global Magnetic Field Disruption.

Fortunately, all all Democrats know the only possible solution to this crisis.

Surely, you can’t be serious.

I think of it as a giant blender where you’re making malt and there’s always a moment where a gob of vanilla ice cream slides around the blender in the milk for a while making a huge racket before finally being pulled into the blades and smoothed out....

There’s probably a big wildly irregular glob or globs of molten material down there somewhere that moves but not as fast as the more liquid stuff and no blades to smooth it all into one even consistency.

That’s as sciencey as I want to get tonight.

Could be the Russians. That darn Putin manipulating the poles/polls.

Oh my. You must get drunk and do both together before everyone finds out you are a nerdgin.
