Earth’s magnetic pole is moving in the direction of Siberia and away from Canada. This is something that scientists have been tracking for a long time. ... the direction of the drifting pole has been roughly the same for as long as scientists have been tracking it. The speed is the issue.
...
Every five years scientists recalculate the location of the magnetic pole. This is important information for global navigation, which includes GPS satellites and other technology. These changes can make a big difference in our everyday lives.

Scientists at NOAA and the British Geological Survey check how accurate the World Magnetic Model is every year and when they did their check this year they noticed some large differences. Primarily that the pole’s movement had sped up. The location data for the pole was supposed to last until 2020 before it needed to be updated but according to experts at the National Oceanic and Atmospheric Administration, it needs to be updated now.
...
The global model was off because of a geomagnetic pulse the occurred beneath South America in 2016. ... The poles movement has sped up in recent memory from 9 miles a year in the 1990s to about 34 miles a year at present day. A new model needs to be implemented as soon as possible and even then they will have to rework the model again in 2020. Until then navigation might be affected.

What caused the geomagnetic pulse beneath South America is unknown. ...

Scientists on Monday released an emergency update to the World Magnetic Model, which cellphone GPS systems and military navigators use to orient themselves. It’s a minor change for most of us — noticeable only to people who are attempting to navigate very precisely very close to the Arctic.
...
The planet’s magnetic field is generated nearly 2,000 miles beneath our feet, in the swirling, spinning ball of molten metal that forms Earth’s core. Changes in that underground flow can alter Earth’s magnetic field lines — and the poles where they converge. Consequently, magnetic north doesn’t align with geographic north (the end point of Earth’s rotational axis), and it’s constantly on the move. Records of ancient magnetic fields from extremely old rocks show that the poles can even flip — an event that has occurred an average of three times every million years.
...
Curiously, the south magnetic pole hasn’t mirrored the peregrinations of its northern counterpart. Since 1990, its location has remained relatively stable, off the coast of eastern Antarctica.
...
Some have speculated that Earth is overdue for another magnetic field reversal — an event that hasn’t happened for 780,000 years — and the North Pole’s recent restlessness may be a sign of a cataclysm to come.

So magnetic reversal.  How badly would that fuck shit up?  I'm assuming the software issues in GPS etc would be the hardest to update.  Also assuming that it would happen over a relatively long period of time - year+++ so affects could be addressed but that's an assumption.... And I didn't read the article or anything

[HornsOverIthaca 2333]

Probably not as bad as a total protonic reversal.  The door swings both ways.

[Llano Estacado 1257]

Right. That's bad. Ok, all right. Important safety tip. Thanks, Ithaca

So we can just set the nukes to a magnetic compass for targeting now?

Don't all the doomsday prepers mention pole reversal right up there with Yellowstone super volcano when they talk about the end of days?

I just watched an doomsday preppers episode where a family was worried about unrelenting F5 Tornadoes. 

Are they just picking these from a hat?

Hagbard, can you put their conclusion (or the significance of it) into English?

Hey you fuckers (who I love), I do worry about F5 tornadoes, Yellowstone having a massive shittastic blowout and EMP's.  You can, and should, mock me by all means - but dammit give me a reach-around first!

Singer and colleagues obtained more precise chronological estimates for the last polarity reversal by using new techniques for dating solidified lava. Basaltic lava, which erupts around 1,100 degrees Celsius (2,012 degrees Fahrenheit), contains magnetite, an iron oxide whose outermost electrons orient themselves along the Earth’s magnetic field. When the lava cools down to 550 degrees Celsius (1022 degrees Fahrenheit), “the magnetization direction gets locked, literally baked into the flow,” Singer says. As a result, the magnetic field’s history is stamped into the solidified lava, which Singer and his team could read using a specialized process to measure the argon isotopes of the decayed lava samples.

Unfortunately for geologists (but fortunately for the rest of us), volcanoes don’t erupt all the time, making lava a spotty record-keeper of the magnetic field’s evolution. To sew together the missing dates, the research team combined the new measurements from seven different lava sources around the world with past records of magnetized elements in ocean sediments and Antarctic ice cores. Unlike lava, the ocean provides a continuous record of magnetization, since grains of magnetic material constantly settle on the seafloor and align with the planet’s field. “But these records get smooth and deformed by compaction, and there’s a lot of critters that live at the bottom of the seafloor… so the record gets destroyed a bit,” Singer says.

Antarctic ice offers a third way of resolving the history of Earth’s magnetic field, since it contains samples of a beryllium isotope that forms when cosmic radiation strongly interacts with the upper atmosphere—precisely what happens when the magnetic field weakens during an excursion or reversal.

By combining all three of these sources, the researchers patched together a thorough story for how the magnetic field evolved during its last reversal. While previous studies suggested that all reversals go through three phases in a timespan no longer than 9,000 years, Singer’s team discovered a much more complex reversal process that took over 22,000 years to complete.

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 wandering of Earth’s north magnetic pole, the location where the magnetic field points vertically downwards, has long been a topic of scientific fascination. Since the first in situ measurements in 1831 of its location in the Canadian arctic, the pole has drifted inexorably towards Siberia, accelerating between 1990 and 2005 from its historic speed of 0–15 km yr⁻¹ to its present speed of 50–60 km yr⁻¹. In late October 2017 the north magnetic pole crossed the international date line, passing within 390 km of the geographic pole, and is now moving southwards. Here we show that over the last two decades the position of the north magnetic pole has been largely determined by two large-scale lobes of negative magnetic flux on the core–mantle boundary under Canada and Siberia. Localized modelling shows that elongation of the Canadian lobe, probably caused by an alteration in the pattern of core flow between 1970 and 1999, substantially weakened its signature on Earth’s surface, causing the pole to accelerate towards Siberia. A range of simple models that capture this process indicate that over the next decade the north magnetic pole will continue on its current trajectory, travelling a further 390–660 km towards Siberia.

"Lobes of flux" might be a decent a band name.
