Earth’s magnetic field is decaying at such a rapid rate that scientists think the poles may flip. New research shows the most significant weakening is happening under Africa, in an area called the ‘South Atlantic Anomaly.’ As well as giving us our north and south poles, the magnetic field blankets the Earth, protecting it from solar winds and cosmic radiation. Without it there would likely be no life on our planet today.
However, the forcefield has weakened significantly in the past 160 years and scientists have suggested that it could be in the process of flipping. Effectively this means a switch in magnetic polarity and would see compasses point south instead of north.
The cataclysmic pole shift hypothesis states that there have been geologically rapid shifts in the relative positions of the modern-day geographic locations of the poles and the axis of rotation of the Earth, creating calamities such as floods and tectonic events.
When the reversed patches grow to the point that they dominate the rest of the core, Earth’s overall magnetic field flips. The last reversal happened 780,000 years ago during the Stone Age, and indeed there’s evidence to suggest the planet may be in the early stages of a pole reversal right now.
