Magnetic North Pole Accelerating Movement Forces Experts to Update World Magnetic Model

Earth’s magnetic north pole has been moving toward Siberia. The magnetic pole is moving so rapidly the world’s experts in geomagnetism are having to update the World Magnetic Model, ahead of schedule.

In the mid 90s its movement more than tripled in speed and by 2001, it had entered the Arctic Ocean. In 2018, the pole crossed the International Date Line into the Eastern Hemisphere.

In 2016, part of the magnetic field temporarily accelerated deep under northern South America and the eastern Pacific Ocean.

By early 2018, Researchers from NOAA and the British Geological Survey determined the World Magnetic Model was so inaccurate it was about to exceed the acceptable limit for navigational errors.

The geomagnetic pulse beneath South America came just as researchers had established the 2015 update to the current model. Researchers say a new version should now remain accurate until next year.
