What the story is talking about shifting is not the magnetic pole. They are talking about the line through the center of the earth that everything is balanced around.
The magnetic pole is not even at the north geographic pole and it wanders around the Islands inside the Canadian Arctic. It changes all the time and you have to correct old maps to new readings.
