The consequences of this process could be dire for our planet. Maybe for civilisation, but not for the planet. The poles have flipped many, many times before.

The consequences of this process could be dire for our planet. Maybe for civilisation, but not for the planet. The poles have flipped many, many times before. Generally speaking, the only effect has been for the upwelling rock in the Mid Atlantic Rift to have symmetrical bands of alternating South and North-seeking magnetism. https://divediscover.whoi.edu/mid-ocean-ridges/magnetics-polarity/ https://divediscover.whoi.edu/mid-ocean-ridges/magnetics-pol... In practical terms, as far as humans and their navigation is concerned, the effect would be similar to the world turning upside down, as North becomes South. I wonder if we'd flip East and West too. Or turn our maps upside down. Probably not.
