Ship Logs Suggest Upcoming Polar Reversal

Nyerp writes "Researchers are using naval logs dating back as far as 1590 to arrive at better estimates of the decline of Earth's magnetic field. The results suggest that there may be a reversal of earth's magnetic field in about 2000 years." Also worth noting, our ancestors have lived through a number of polar reversals, and we're still here, so no need to fret!

    we may lose a few species in the process. But, that's how nature works.

    If only that was all that would happen... It's really much more of a crisis than that. Trillions of USD will be spent trying to save these species after they are put on the endangered species list in the U.S.

    I can see it now, electromagnets will distributed throughout the U.S. to keep the field unchanged within our borders - every building built will be required to have a giant solar array and giant batteries powering giant magnets to "do their part" to maintain the magnetic field as close as possible to what it is today...

    ...then the damn birds will prove to be stupid ingrates who just fly over the US border and, once exposed to the "new natural magnetism", instantly go into some sort of horrible spiral flight pattern until they die of exhaustion.

    Oh, and don't forget the endless productivity sapping debates on "is man causing the magnetic shift or is it just a natural phenomena".

    Folks, this will be a disaster.

    I'm sure many individual birds will get screwed, and we may lose a few species in the process.

    According to Wikipedia, magnetic reversals happen from 1 to 5 times per million years. That is not long enough time for a new species to evolve. Which in turn means that every currently existing bird species survived the last reversal. So why would they perish this time either ?

    Of course we might get lucky and the migrating flocks of bird-flu carrying birds who were about to wipe out the human species will all get lost and drown in the middle of the Atlantic. Once again, the day is saved, thanks to Geomagnetic Reversal !-)

    You wanted to know how computer hard drives and magnetic storage media will cope with the field reversing?

    Well, there is a very easy test you can do. Simply take you computer hard drive or floppy disk, and rotate it by 180 degrees in the horizontal plane. (That's pi radians for you maths people out there!)
    Now, notice any difference in the operation? i suggest we all to this at once to ensure that everything we own is compatible with the switch over.
