Earth Magnetic Field Reversal
Earth Magnetic Field Reversal
(OP)
A while back, I was watching a program on one of the "Learning Channels" that mentioned evidence of Earth's magnetic field reversals (several) oberved in lava deposits on ocean floors.
If these reversals really did happen, it couldn't have been instantaneously for each event. Did it take days, months, or years? What were the effects of cosmic radiation during the field collapse? What happened to animals dependant on the field for navigation? I haven't Googled yet, a different topic on the motor forum reminded me of the question.

One PBS Nova program brought up the fact that lava deposites in Oregon(?) investigated by one researcher indicated that during a past transision phase the field may have reversed almost several times a week before settling down.
There has been a past Eng-tips tread on this issue.

Maybe we will suffer a radiation peak. Maybe boats, planes and birds will get lost. Maybe it will cause disturbance of Coriolis force and because of that we will have an increase or change of hurricanes occurrence.
If earth reverse polarity coincides with a solar flare all the above occurrences will be potentated
“NASA predicts that, rather than declining to zero gauss, the magnetic field would become disordered. Thus we might for short time have more than one north and South Pole on the planet. This official scientific stance says that the magnetosphere, which shields us from cosmic radiation, would not entirely disappear either. Thus, while communications would be erratic and perhaps at times completely inactivated, humans would find ways to survive. However, there are dissenters in the ranks, pointing to the vast South Atlantic magnetic anomaly and radiation damage to satellites over that region attributed to weakening of the protective magnetosphere.”

Global warming will be blamed.

During earth reverse polarity maybe we will suffer a radiation peak by interaction with radiation that travels through vacuous space at the speed of light and propagates by the interplay of oscillating electric and magnetic fields (electromagnetic radiation "photoionization"). This ionisation is of course dangerous for humans and can led to skin cancer.

in some situations vaselin would also works.

I have also heard that the 20,000 yr schedule for these events corresponds to this solar system's oscillating orbit thru a layer of the milky way.
