I think the greater issue at hand is the rapidly weakening of earths magnetism and magnetic feild. Not to mention the fact we are in the middle of a geomagnetic excursion. The last time this happened was the laschamp event which is argued to be the event that killed Neanderthals.

Per this paper the last time there was a validated geomagnetic excursion was Mono Lake, 8,000 years after Laschamp.

Not really an "event", as it lasted 1,000 years, but there is indeed one paper which argues this. Comments published on that paper (essentially mini-papers of their own) indicate that that is a fairly controversial claim.
However, that may not be a near-term concern, as the earth's magnetic field has weakened only 10% over the last 180 years, and is apparently not likely to flip any time soon.
