Earth’s magnetic field also weakening dramatically. Could even lead to magnetic reversal. Scientists don’t know why.
Earlier this year, both the US National Oceanic and Atmospheric Administration (NOAA) and the British Geological Survey (BGS) were forced to update the World Magnetic Model* due to the speed with which the magnetic north pole is moving out of the Canadian Arctic and toward Siberia. It has been moving at an average speed of 55 km over the past twenty years,” the US agency said in a press statement.
Compilers also confirmed that the Earth’s magnetic field is continuing to weaken, at a rate of about 5 percent every 100 years.
(Note: I disagree. SWARM satellites show that the weakening has accelerated dramatically – to 5 percent per decade. See “Earth’s magnetic field weakening ten times faster than thought.“)
Scientists Can’t Explain It
Dr. Ciaran Beggan, a geophysicist and geomagnetic specialist from the BGS, told FT that the movement of the pole has been “much faster” since the 1990s “than at any time for at least four centuries,” and that scientists “really don’t know much about the changes in the core that’s driving it.”
With the pole passing the Greenwich (prime) meridian and continuing its race east, humanity is entering the unknown, scientifically speaking.
Scientists have previously expressed concerns about the movement and its possible impact on the magnetic field protecting Earth. Without the field, Earth would be left vulnerable to solar flares, which could damage everything from spacecraft to power grids. The US National Academy of Sciences has calculated that a repeat of a solar storm like the one which hit the planet in 1859 (the Carrington event) could cause as much as $2 trillion in initial damage, and take a decade to repair.
Furthermore, a weakened magnetic field may lead to a potentially cataclysmic geomagnetic reversal . Some scientists believe that another reversal may be due soon, even though such an event could take centuries to complete. (I disagree with this one, too. I think it could take place in a matter of years.)
