Earth’s Poles Could Be ‘About To Flip’, Report

The Earth’s magnetic poles could be about to flip, sparking chaos and making large parts of the planet uninhabitable, a new study claims.

Science author Alanna Mitchell has delivered the stark warning in an article that declares the Earth is “under attack from within” and that a shift in poles could have dire consequences.

Ms Mitchell warned that a shift means the important shield surrounding the Earth called a magnetic field could be “compromised for centuries”.

She wrote: “Because grids are so tightly coupled with each other, failure would race across the globe, causing a domino run of blackouts that could last for decades.

“The shield could be compromised for centuries while the poles move, allowing malevolent radiation closer to the surface of the planet for that whole time. Already, changes within the Earth have weakened the field over the South Atlantic so much that satellites exposed to the resulting radiation have experienced memory failure.

“It turns out that the dipole — the orderly two-pole magnetic field our compasses respond to — is under attack from within.

“The Earth’s magnetic field protects our planet from dangerous solar and cosmic rays, like a giant shield. As the poles switch places (or try to), that shield is weakened; scientists estimate that it could waste away to as little as a tenth of its usual force.”

Since the last shift, the world has changed drastically – there is now close to 7.6billion people inhabiting Earth, this is twice as many as in 1970 alone.

The European Space Agency’s Swarm trio claims that a flip could be imminent, according to their satellite data.

Scientists have added that molten iron and nickel are sapping vital energy from the Earth’s core – this is near the spot where the protective magnetic field stems from.

The situation inside the planet’s core appears to signify a flip.

The author went on: “That radiation isn’t hitting the surface yet. But at some point, when the magnetic field has dwindled enough, it could be a different story.”

Ms Mitchell cites from Daniel Baker, the director of the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, that believes the devastating galactic cosmic rays and ultraviolet B rays “from a radiation-damaged ozone layer” could kill “living creatures”.

In addition to harmful results to life, “satellite timing systems that govern electric grids would be likely to fail”, according to Ms Mitchell.

She added: “No lights. No computers. No cellphones. Even flushing a toilet or filling a car’s gas tank would be impossible. And that’s just for starters.”

The Earth is protected from harmful solar and cosmic rays thanks to the magnetic field – when the planet’s poles shift, which they typically do every 200,000 or 300,000 years, the proactive barrier is hampered.

Because the last flip occurred 780,000 years ago, to say Earth is due for a pole shift would be an understatement.

The author explained: “Today, we know that the poles have changed places hundreds of times, most recently 780,000 years ago. (Sometimes, the poles try to reverse positions but then snap back into place, in what is called an excursion. The last time was about 40,000 years ago.)

“We also know that when they flip next time, the consequences for the electrical and electronic infrastructure that runs modern civilisation will be dire. The question is when that will happen.

“Geophysicists have tried to answer that question through satellite imagery and math. They have figured out how to peer deep inside the Earth, to the edge of the molten, metallic core where the magnetic field is continually being generated.”
