| Oh wait. I guess that's 34 miles per year. Still a lot. - Quote :
- There have been a few theories about why the pole's movement has increased in recent years -- from around 6 miles a year between 1900 and 1980 before accelerating to around 24 to 31 miles a year in the past two decades. Some scientists think a jet stream of molten liquid is pushing the north pole, while others have suggested that the south and north magnetic poles are reversing positions.
If the poles reverse, there will be some map updating (and mapping applications) required.  |

| Nah. Just swap the labels on your compass. |
