Magnetic north is moving at a rate of 34 miles per year, up from 9 miles per year in 2000. And there's nothing humanity can do but try to keep up. Turbulence in the planet's liquid outer core shifts Earth's poles in ways that are "unpredictable," leaving researchers scrambling to track the changes.

This doesn't mean you can't trust your favorite mapping app. While the World Magnetic Model does play a role in GPS services, those rely primarily on satellites to get you from A to B. Just don't be surprised companies and governments alike have to work that much harder to adapt, especially for Arctic expeditions where north pole changes would be much more noticeable.
