If the Geomagnetic field keeps weakening at its present rate, the whole world will be seeing the aurora, which although pretty would present a few difficulties, even without a CME.


Of course we don't know if it's a short term blip in the data, which doesn't go back very far directly, and I've not heard about any techniques to establish the strength of the magnetic field from enviromental records, or the start of a full magnetic pole inversion...
