[...] At the heart of the matter, geologists believe, is a disturbance in the outer core of the Earth’s interior (2900km below the surface). This superheated pool of molten metal is what generates the magnetic field.
“If we look at our best numerical simulations of a magnetic field reversal, this is the type of pattern we see right before a reversal,” says Professor Tarduno. “We don’t know if the current (anomaly) will lead to a full reversal.”
If the anomaly continues to grow, a larger patch of near-orbit and our planet will become increasingly exposed to harmful rays and solar storms.
The last time Earth’s magnetic poles reversed was some 780,000 years ago.

Something strange is going on at the top of the world. Earth’s north magnetic pole has been skittering away from Canada and towards Siberia, driven by liquid iron sloshing within the planet’s core. 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 error is increasing all the time,” says Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s (NOAA’s) National Centers for Environmental Information.

It's a Chinese conspiracy to undermine our economy because the people all around the South Atlantic oppose The Wall and there are colluding ! No further studying shall be allowed, and anyway NASA is furloughed.
Done. The rest of the comments can be about core/mantle physics.

Pole shift on the way. Get ready for lots of clouds reflecting sunlight, leading to a mini-ice age.

So many have been added recently (using public money) to store the rich. They and their fat-filled bodies will be stored there until the surface of the planet can become habitable again.
If something has become public, it has been going on for much longer and plans have been developed to save the secret society members (the puppet masters) from dying. Deep underground military bases are just one part of it.
It is also possible the magnetic disturbance is being created to kill off most of the planet's inhabitants. If you don't know you are being systematically murdered, you haven't been paying attention.

I suspect this thread so far consists of mostly "gallows humor".

Then where is the gallows? I doubt somehow that he thinks that a magnetic field reversal will just result in a few confused birds.

We can't use the same argument about the energy infrastructure or electronics, though.
Given their pervasiveness and role in the civilization, one may look into the effects. Or not.
Very much like in the case of climate warming when you can relocate zillions a bit higher the mountain, so why worry? It's not like money grow in a tree and the civilization won't survive if we use money on things that have not yet happened, right?

True. There probably will be some sort of problem. And until we experience this effect, we'll never be sure what flaws we'll find.
Indeed. I think the cases are quite similar. We have hyped problems with rather simple and relatively cheap adaptation to the problem (here, just replace infrastructure that breaks with more durable infrastructure - lather. rinse. repeat until the infrastructure stops breaking.). Meanwhile the Chicken Littles are ignoring all the other big problems we have in favor of their pet problem. Funny how they keep talking about the future while ignoring huge things that matter to the future.
