Basically, to find true north from magnetic, when going east, suptract 14 degrees, when going west, add 14 degrees, and also I know that it is revised every year as the poles and magnetic field of earth is always shifting, in the early ages of sailing it was 12 degrees or something... This "Event" I do not beleive is something that will happen overnight, it is an ongoing process that will never stop.
I blame the shape of the earth for this, and the widening of the equator.
