Geomagnetic reversal

A geomagnetic reversal is a change in the Earth's magnetic field such that the positions of magnetic north and magnetic south are interchanged.

This happens about every million yeas the last one 780,000 years ago. Since there is not set schedule this could occur any time.

What consequences could we expect .... How would you prepare ....

    Dec 11 2012: Has it been 780,000 years? How time flies! Speaking of flying, I don't think birds know the meaning of words like North and South. If the lines of flux swap end-for-end our feathered friends won't know the difference. We literate creatures could implement a corrective algorithm for our word-based systems. North will be 180 degrees, South will be 360 ( or zero) degrees. Or, even better, we could just ignore the event and fly like the birds! Ignorance is bliss! Thanks for the diversion from the fiscal cliff.

      Dec 11 2012: Edward, I wrote another conversation, that was not allowed, that I thought would be fun and as you say a great diversion. .... The Mapimí Silent Zone (Spanish: La Zona del Silencio) is the popular name for a desert patch near the Bolsón de Mapimí in Mexico overlapping the Mapimí Biosphere Reserve that is the subject of an urban myth that claims it is an area where radio signals cannot be received. .... The committee did not think this was a approperiate area of conversation. As I read about it there were some strange things that occurred there. You may enjoy looking at a article on the web about this for funnsies.

      I should have stuck to conversatins that would be more acceptiable and agreeable like sex, politics, and religion ...... no disagreements there .... LOL

      Be well my friend. Bob.

        Dec 11 2012: Do I need my Thinking Cap, or my tin-foil hat? Based on some of the recent OP's I was wondering if anything got denied publication. Sorry to hear you suffered the humiliation of a rejection. My turn is coming I expect. Be of good cheer. . . . anyway!

          Dec 11 2012: The type of hat would depend on if you are posing for a sculpture or desiring better TV reception.

          I am so depressed I had two egg nogs sans booze and may have a soda tomarrow.

          Do I need a designated driver ... I have never been on a drinking spree before?
