A new study indicates that there is a possible connection between the Earth's inner core and a magnetic reversal. The magnetic field reverses direction every few thousand years. If it happened now, we would be exposed to solar winds capable of knocking out global communications and power grids. Now the researchers say that there are signs that the next magnetic pole reversal may be underway. The rapid movements of the field's axis to the east could be a precursor to the poles trading places.
