I did answer your question.
To your reply, naturally over millions of years, yes.
Over 12,000, not so much. Greenhouse gas emissions have increased our atmospheric CO2 and methane density. Our polar ice should not have started a meltdown yet. We didn't even account for an acceleration in ice loss due to decreased reflectivity caused by said ice loss.
What happens if the change in mass distribution on the earth surface cause an acceleration of the magnetic polar movement ?
Nobody knows. What we know is we did this to ourselves. Because using a gas car was just too convenient, and parading a rebel flag on the ass end of a souped up pickup is 'badass'. Mentally challenged indeed.
