The Magnetic North Pole Just Shifted—Here’s What It Means
The Earth's magnetic north pole has been on the move for decades, but its recent rapid shift has scientists and navigators paying close attention.
Typically drifting at a slow pace, the magnetic north pole is now moving at an unprecedented rate of about 34 miles per year, heading toward Siberia.
This shift affects navigation systems, compasses, and even wildlife that rely on the Earth's magnetic field for orientation.
Air and sea travel, GPS systems, and military operations must regularly update their data to account for the pole's movement.
For example, airport runways, labeled based on compass directions, often require renumbering to match the updated magnetic field.
Scientists believe the pole's shift is linked to changes in the Earth's molten iron core, which generates the magnetic field.
While the shift is not a sign of an imminent geomagnetic reversal (where the north and south magnetic poles swap places), it raises questions about long-term implications.
