==Explanation==
Over the last couple of months, {{w|Earth's magnetic field|Earth's magnetic fields}} have been [https://www.nature.com/articles/d41586-019-00007-1 shifting rapidly]. Although the magnetic fields do move regularly, the current shift has been unexpected and unprecedented. As many location systems are reliant on the magnetic fields to function, the accuracy of such tools is being shifted beyond the maximum acceptable error.

Locational and navigational systems use the magnetic field, combined with a model of field behavior, to do fancy math and pop out data. Because of the rapid shifts, a new model was scheduled to be created; however, the model has been considerably delayed by the {{w|United States federal government shutdown of 2018–2019|US government shutdown}}.

As shifts occur, the error of geopositional data will increase until a new {{w|World Magnetic Model|model}} is released. The effect is especially pronounced as you move toward the poles. 

Cueball is saying that because of the currently published {{w|magnetic declination}} data being slightly incorrect, his {{w|Schooner|schooners}} (old merchant sailing ships) may go off-course and crash on {{w|Shoal|shoals}}. This is to illustrate how magnetic pole shift doesn't actually affect many people's daily lives.  Modern ships' navigation systems do not rely on magnetic pole location &ndash; in contrast to old vessels which mostly used a {{w|compass}}.

Since the movement is only about two-fifths of a degree, it wouldn't cause much disruption for [[Cueball]] or require him to adjust anything about his lifestyle, but since the speed of the change has been steadily increasing over the past few years, it may mean we are heading for a geomagnetic reversal in the next few decades, something very exciting indeed. During a magnetic reversal, the poles wouldn't just switch places; several different poles would form and interact chaotically, and it's likely that one of them would end up close enough to where [[Randall]] lives to cause auroras to become more common at some point during the transition.

In the title text, Randall mentions that there are reasons people could be concerned, but says that they would be more than made up for by newly being able to experience mid-latitude auroras. Since auroras occur between 10° and 20° from the magnetic poles, the migration of the poles to middle latitudes would cause the auroras to occur there as well; since more people live at middle latitudes than in the Arctic and Antarctic Circles, and since auroras are considered aesthetically attractive, the psychological benefits of the drifting poles might more than make up for the technical difficulties it causes.

:[White Hat and Cueball are talking to each other. White Hat has a cellphone in his hand, while Cueball is raising his hands in the air in mock exasperation.]
:White Hat: I just read that the Earth's North magnetic pole is drifting rapidly.
:Cueball: Oh no! I must update our declination tables post haste, lest our merchant schooners run aground on the shoals!

:I like when the Earth's magnetic field does weird stuff, because it's a huge, cool, urgent-seeming science thing, but there's nothing I personally need to do about it.
