I didn't say earth's magnetic field was going to flip.
But since 1860 the earth has lost 20% of the field strength, most of that 20% since 2000.
Thr north and south poles have moved more in our lifetimes than they did previously going back to the1600s.
This may be a magnetic excursion, where the poles move so far then go back. The earth's magnetic field strength is pretty much guaranteed to drop at least 50% and will likely fall below 20%.
For all we know the only thing that might be able to flip the poles is when a super solar storm hits during a magnetic excursion and pushes the poles a full 180 degrees. The magnetic excursion may be a regular event happening every 10 to 20 thousand years.
