| Earth's magnetic north is shifting at an 'unprecedented' rate of 30 miles a year - throwing satellite positioning data and navigation systems off course |

| #10 Refrigerator magnets? No no no. It's all about magnetic signage on stealth campers migrating with the weather. |

| #8 As we all know, magnets generate both an attractive and a repulsive force. Rather than being attracted towards Siberia, I theorize that the movement of the pole is being driven by the ever-increasing concentrations of refrigerator magnets in the Southern United States, particularly in Texas. |

| #6 ...yeah, our pole star Polaris was not the Egyptian pole star when they made the pyramids. Let's just say we're good for our lifetime. |

| #5 Re #4 - Except that, IIRC, the earth is slowly moving so that in a few thousand years or so, Polaris will no longer be the north star. Of course, the whole "magnetic north moving" thing can be blamed on global warming. Which is all Trump's fault. |

| #4 Celestial navigation will remain accurate nonetheless. |

| #3 Using a map and compass would be thrown off, in time, but even then you tend to use the topography of the map more than the magnetic north. |

| #2 The idea that GPS depends upon magnetic pole information surprised me. I'm not an expert but once your satellite is in orbit you don't adjust that orbit except by using a ton of fuel (or because you're adjusting altitude). I don't see how magnetic field is a factor at all. |

| #1 After circling northern Canada for hundreds of years, the approximate location of the magnetic north pole started moving speedily towards Siberia at around the turn of the century. It's the damn Russians behind everything!!! |
