What If Earth's Magnetic Poles Flip?

What If Earth's Magnetic Poles Flip? | Geography Education |
What will happen if or when the direction of Earth's magnetic field reverses, so that compasses point south?


A simple question, but this is a hypothetical that could profound affect the planet.  A magnetic reversal isn't instantaneous, but is a process that takes between 1,000 and 10,000 years to complete.  That transition is what would be difficult to weather since a strong magnetic field helps protect Earth from solar radiation blast.  The technology we depend on for communication would be in great jeopardy...the list of possible ramifications is extensive.

I'm just happy to find out that we don't all simultaneously drop dead. Seriously, though, life has existed on this planet for a long time. The poles have flipped a lot over that span. Shielding technology from the effects is very important in our digital world, but apart from that we should be fine. This doesn't really worry me. The Yellowstone Caldera does, but that is a whole different story.

If the mangnetic field of the Earth is moving,like it has in the past, would that explain all the natural disasters that has accured in the past ten years? If the magnetic fields are weakened, and solar flares do knock out our communication, and electricity what would happen to society, would we panic, become hostile, or would we stay logical and withhold the laws.
