All The Crazy Things That Could Happen When Earth's Magnetic Poles Reverse

The circle of life and the circle around our home planet go hand in hand in many ways. That circle is known as a magnetic force field, or a magnetosphere. Without it, there could not be life on Earth. This protective, magnetic layer that extends out into the atmosphere, deflects harmful particles and rays, and is the singular distinction between Earth and other planets like Mars (which was long considered a dead planet, though maybe not for much longer). Earth's magnetic field is approximated 3.5 billion years old, but just because it’s existed for so long doesn’t mean that it’s always been stable.

Throughout history, flipping magnetic poles have caused unfathomable turmoil to the world. Negative effects of magnetic shifting can range from unlivable weather to blackouts and even extinction. Unlike other predictions, these events are not merely hypothetical scenarios. They’ve already happened in the past and might be doomed to repeat. Scholars of the Ice Age and the Mesozoic Era have learned through fossils the startling consequences of the weakening of our planet’s magnetic force field and how this erosion can give way to detrimental shifting. The rest of us are playing catch up.

So, what are the Earth’s magnetic poles and what happens if our magnetic poles flip? The answer will surely shock and astonish you.

  • Pole Shifts Could Give Rise To A Super Volcando

    A look back at the last major pole shift - called the Laschamp Event, wherein radioactive ice sheets floated over our planet’s fragile surface - links the magnetic force field shift with yet another catastrophe, a super volcano. This volcano was the largest and most deadly of its kind to the best of our scientific knowledge. It spawned via an outer space collision wherein high energy protons spewed out of the sky and pretty much melted everything because the magnetic field was weakened. 

  • Mars Died When Its Magnetic Field Died

    Everything dies - even planets and stars. And Mars is no exception. 

    Mars is the most habitable planet scientists are aware of at this point in time. It contains many Earth-like features that would make it ideal for beings. It is said that Mars once contained oceans, greenery, and probably life but all of that changed when its magnetic field died, an event that happened gradually and naturally. Today the dead planet more likely than not contains no sustainable life. 

  • Three Of Every Four Species Died Off In The Last Polar Switch

    While homo sapiens appear to have survived, and maybe even evolved, during the harsh conditions of the Pleistocene Epoch, approximately three quarters of the rest of Earth’s wildlife tragically died out. Among them are the wooly mammoth, saber tooth tigers and, of course, dinosaurs, but it wasn’t people that killed them. According to LiveScience, the culprit was an unidentified, extraterrestrial object that breached the planet’s atmosphere by drifting through a weak spot in the magnetic field at a time when the field was vulnerable due to magnetic shifting.

  • The Weakest Sections Of The Magnetic Field Hover Over The Americas, The UK, and Russia

    Since the weakest regions in the future will be those lacking magnetosphere protection, it might be useful to know exactly where they are. As of late, the Western Hemisphere contains the weakest sections. These conditions are subject to change at any given moment though, since much of today’s conditions contradict previous scientific expectations.
