I have known that the Earth has seen North become South and vice versa in eons past, but this is a sobering take on what would happen to our modern civilization:

Fake news: Humpherys proved that it is just getting weaker exponentially.

A lot of preparation and then nothing happened. Perhaps nothing happened *because* of the preparation.

No problem- Elon Musk will build us a bigger magnet:) JayInOz

So would the water circling the plughole rotate the other way?

Earth's Magnetic Poles Are Overdue For a Switch And We're Not Prepared (ARTICLE LINK) (https://www.sciencealert.com/earth-magnetic-poles-reversal-switch-overdue-turbulent)



Excerpt
Earth's magnetic field is pretty adept at flipping polarity. The poles have swapped, reversing north and south, many times over the planet's history.

Within the last 20 million years, Earth has fallen into the pattern of pole reversal every 200,000 to 300,000 years, and between successful swaps, the poles sometimes even attempt to reverse and then snap back into place.

About 40,000 years ago, the poles made one such unsuccessful attempt, and the last full swap was about 780,000 years ago, so we're a bit overdue for a pole reversal based on the established pattern.

The planet's magnetic field is already shifting, which could signify the poles are preparing to flip, and while we can't yet confirm that a reversal is on the near horizon, it is well within the realm of possibility.

While a pole reversal isn't entirely uncommon when you consider Earth's history, this time it could have serious implications for humanity.
