Comment Comment by politelemon > It has been speculated whether the current weakening of the field is a sign that Earth is heading for an eminent pole reversalIt's not often mentioned but these pole reversals aren't sudden/instantaneous across the planet. They can take a few thousand years to complete.See: https://en.wikipedia.org/wiki/Geomagnetic_reversalThe most interesting part to me, from the Wikipedia page is:> The magnetic field will not vanish completely, but many poles might form chaotically in different places during reversal, until it stabilizes again. parent politelemon 6 years ago
