Due to the surprisingly fast shift in the magnetic field, scientists are having to update their magnetic models sooner than expected, as the accuracy affects worldwide navigation…even your smartphone. (GPS is only one element used in determining your location, speed, and direction.)

The Earth’s magnetic field protects us from cosmic radiation and energy outbursts from the sun. It also allows the world’s power grids to remain stable.

Scientists don’t know why the magnetic motion is accelerating, but they have some interesting theories. Check out this excellent article from the UK’s Daily Mail. (I borrowed their animated .GIF for this post.)    https://www.dailymail.co.uk/sciencetech/article-6579515/Scientists-warn-Earths-magnetic-North-Pole-begun-moving-erratically-speeds-50km-year.html
