Thanks, Aaron. From what I can tell, today's magnetic pole drift toward Siberia doesn't look like part of a pole reversal. (Though I'm not a scientist and could be wrong.) Here's a quote from an article : https://earthsky.org/earth/magnetic-north-rapid-drift-blobs-flux/

"Models of the magnetic field inside the core suggest that, at least for the next few decades, the pole will continue to drift towards Siberia.

"However, given that the pole’s position is governed by this delicate balance between the Canadian and Siberian patch, it would take only a small adjustment of the field within the core to send the pole back to Canada."
