The Earth’s magnetic north pole is on the move again, drifting closer to Siberia at an accelerated rate. Scientists have released an updated World Magnetic Model (WMM), revealing that the pole has moved even further away from its fixed geographic counterpart in just five years.
Unlike the geographic North Pole, which remains stationary, magnetic north is constantly shifting due to changes in molten iron within the Earth’s core. This shift is not new, but in recent decades, it has accelerated dramatically, leaving scientists scrambling to update navigation models.
The WMM is critical for ensuring the accuracy of modern navigation systems, including GPS and aviation. If left unupdated, errors can accumulate, leading to navigation mistakes that could impact aircraft, ships, and even military operations.
To address this, scientists have released two versions of the new WMM: a standard model with a resolution of 2,051 miles at the equator and a high-resolution model with an 186-mile resolution. The difference for most everyday users is negligible, but major airlines will need to upgrade their navigation software to accommodate the shift.
The continued drift of magnetic north signals that Earth’s magnetic field remains in flux. While a full magnetic reversal isn’t likely in the immediate future, scientists will continue to monitor changes and improve models to ensure that navigation systems keep pace with the shifting landscape of our planet’s magnetism.
