Knowing the precise location of the Earth's magnetic north pole is something which is absolutely necessary for those who rely on compasses -- or who operate airplanes and boats -- and with its excessively fast shift, scientists have just updated the location of the magnetic north pole well ahead of schedule.
According to Phys.org, because the super fast drift of the magnetic north pole is something which has been occurring for decades now, absolutely precise navigation today is an impossibility. With this in mind, on Monday scientists decided to give an updated location for the magnetic north pole -- one whole year ahead of when they had originally planned to.
If you're wondering just how far the magnetic north pole is currently drifting, the answer is a lot. With each passing year, this pole has been found to shift around 34 miles. In fact, in 2017, it even managed to cross the international date line. The north pole is migrating, well on its way to Siberia right now.
While the swift shift of the Earth's magnetic north pole isn't interfering with GPS in any way -- as this system is based upon satellites -- it is a super big deal for the military, who need to nail the position down for navigational purposes -- and also to plan reliable parachute drops.
NASA, the U.S. Forest Service, and the Federal Aviation Administration also rely on it too -- so knowing its precise location is a pretty big deal for many people.
