Are you referring to the magnetic pole switch? That happens every 200-1M years, according to patterns on the seafloor. It’s been estimated that the last reversal was 780,000 years ago, so it theoretically could be any day now.

With that being said, I doubt that humanity will agree to turn all maps 180° to correspond.

I thought they were referring to the fact that under the ice its an archipelago, so if the ice melts it will have southern coasts again

If it melts, they'd all be northern coasts.

It's referencing the pole swap.

Since it's an archipelago underneath then most, if not all, of those islands would have a southern coast. The only way to not have a southern coast is to have the landmass directly on top of the pole, which could only happen for one island (if no ice is present)
