Due north is always moving and always has because of our axial precession. It takes about 26,000 years or so for the full cycle. That's nothing new. We're slightly more oblate than spherical at the equator, which also affects this wobble, like a spinning top. Polaris (which is actually a triple star at the end of the Little Dipper's "handle") will no longer be our pole star in about 1,000 years, because of this movement. But this is perfectly normal for the earth and nothing to worry about. When the Egyptians built the pyramids, Thuban was our nearest pole star. In about 13,000 years, the pole star will be Vega. And in a little over 27,000 years, the cycle will bring us back to Polaris. https://www.youtube.com/watch?v=0qHjtp4cdCA
