Good points. From the image posted above in the thread, magnetic north is somewhere north of Canada. Also read that it is moving about 30 miles/yr toward Russia. So it is just currently moving back closer to true North. Cannot see how that should be considered an extreme movement. Perhaps when it moves all the way down into Russia. There is however acceleration or velocity affects to consider. How fast it is moving, which seems to be very fast.
See post 162 for current location of magnetic pole.
