In the depths of the Earth's surface, liquid iron is circulating at its core, causing the North Pole to move away from Canada and Siberia. This has prompted experts in global geomagnetism to undergo an urgent upgrade of the World Magnetic Model, where it will alter exactly where the North Pole is. The next update was not scheduled to happen until 2020, but due to the sudden change of the North Pole, the researchers need to take it forward.
Accuracy of where the North Pole is needed for GPS worldwide, and is currently close to exceeding "the acceptable (safe) limit for navigation errors," reports the journal Nature.
Arnaud Chulliat, a Colorado Boulder geomagnetist and the National Oceanic and Atmospheric Administration's National Environmental Information Centers (NOAA), said: "The error is increasing all the time.
"The fact that the pole is accelerating makes this region more prone to big mistakes."
Researchers say the pole is moving at 55 kilometers a year, and is becoming more unpredictable in the last 100 years.
While there is no solid explanation as to why this is happening, scientists believe it may be due to a massive section of liquid iron that is changing inside the planet.
Nature reports: "The rapid movement of the north magnetic pole may be connected to a high-speed jet of liquid iron under Canada."
Phil Livermore of the University of Leeds said at a meeting of the American Geophysical Union: "The location of the magnetic north pole appears to be governed by two large areas of magnetic field, one below Canada and one below Siberia.
"The Siberia patch is winning the competition."
The change may also be due to a possible reversal of imminent poles where the north becomes south and vice versa.
In recent years, scientists are gearing up for a potential turnaround in the magnetic field – a natural phenomenon that occurs every 200,000 to 300,000 years as the north and south poles change.
The Poles tried to trade 40,000 years ago, but the process failed.
As a result, the last time the poles switched places was 780,000 years ago, which means we are long overdue in a reversal of poles.
Scientists have warned that once the process has begun it may take a thousand years to complete.
During that time, the Earth's magnetic field will be compromised, leaving living beings on the planet vulnerable to an increased dose of radiation from the sun.
