The planet's magnetic north pole is migrating. Since the mid-1990s, it's wobbled away from the Canadian Arctic and toward Siberia — which can have an effect on everything from shipping routes to the GPS in your phone. Why does the core drift in the first place? Why is it moving at a faster rate today than it has in the past? And what happens if it keeps moving?
Thursday on MPR News with Kerri Miller, guest host Tiffany Hanssen will talk to a scientist who's helping to draw up the new geomagnetic maps, five years ahead of schedule.
Guest:
Brian Meyer — Geomagnetic data manager at NOAA National Centers for Environmental Information.
