   Something big is happening 3,000 kilometers underground, where Earth's inner ocean of molten, magnetic iron generates the global magnetic field.

   The strong parts of the field near the poles are changing, too, getting weaker over Canada and stronger over Siberia.

     Earth's magnetic field is changing, with its weak spot (the South Atlantic Anomaly) growing significantly over the past decade.

     No, it's not doomsday...but it does affect the radiation doses hitting satellite that pass through that region.
