It all sounds like doomsday – or at the very least random chaos, which may all be caused by the imminent shifting of the North and South Pole – so scientists say.
According to research and data sets collated by European Space Agency satellites called Swarm, the Earth’s magnetic field has been weakening. This has meant big weak spots over the Western Hemisphere while the field has been strengthened over the Indian Ocean. One explanation given for this was that the poles were getting ready to flip. Hence compasses that once pointed north, would now point south.
It’s thought that the Earth’s magnetic field is generated by the movement of the currents of the Earth’s molten core at its centre, a process known as “geodynamo.” As these currents are not consistent, the magnetic field also moves around and the magnetic north is currently drifting circa 10 miles per year.
But a complete flip? Complementing the Swarm’s data, geophysicists have been studying the core’s lava that has reached the surface of the earth. Once the lava solidifies, the remaining rock samples provide an indication of what activity is happening with the magnetic field.
