Yes, magnetic pole reversal doesn't seem to follow any particular periodicy, but the current orientation seems to have persisted for quite some time now and field strength has apparently weakened by about a third in the last 2,000 years.
I doubt the movement of ice has anything to do with the earth's magnetic field.
