Deep below the earth's surface, liquid iron revolves around its core, causing the North Pole to move away from Canada and into Siberia. This has prompted global geomagnetism experts to undergo an urgent update of the World Magnetic Model where it will change exactly where the North Pole is located. The next update was not scheduled for 2020, but due to the sudden change of the North Pole, researchers have to carry it forward.
Accuracy of where the North Pole for GPS is needed around the world, and is currently close to except "the acceptable (safe) limit for navigation errors," Nature magazine reports.
Arnaud Chulliat, geomagnetist at the University of Colorado Boulder and the National Environmental Information Centers of the National Oceanic and Atmospheric Administration (NOAA), said: "The error always increases. [1
Researchers say the pole moves 34 miles (55 km) a year, and is becoming increasingly unpredictable over the last 100 years.
Although there is no comprehensive explanation as to why which is happening, scientists believe that this could be due to a massive section of displacement of liquid iron in the planet s interior.
Nature report: "The fast movement of the north magnetic pole could be connected to a high-speed jet of liquid iron under Canada. "
Phil Livermore of the University of Leeds told a meeting of the American Geophysical Union:" The position of the magnetic north pole appears to be regulated by two large-scale magnetic fields, one under Canada and one under Siberia.
"The Siberian patch is winning the competition."
The shift could also be due to a possible inversion of the upcoming pole, where the north becomes south and vice versa.
In recent years, scientists have prepared for a potential reversal in the magnetic field – a natural phenomenon that occurs every 200,000-300,000 years when
The poles tried to exchange 40,000 years ago, but the process failed.
As a result, the last time the poles passed into place was 780,000 years ago, which means we are lagging behind a pole reversal.
Scientists have warned that once the process has begun, it may take 1,000 years.
During this period, the Earth's magnetic field will be compromised, leaving living beings on the planet vulnerable to an increase in radiation dosage from the sun.
