I was watching National Geographic Naked Science today, high as a kite. One show was about the dinosaurs getting wiped out by the asteroid, but the next show was about the Earth's magnetic field and the final conclusion was that we are shit out of luck.
But at least not for 1,500 years so we are all good. I digress.
The rotation of the inner liquid core against the semi-liquid mantle is what creates the magnetic field that protects us from the solar winds and radiation that would make us look exactly like Mars.
NASA confirms that Mars does have some sort of magnetic field left, but for whatever reason the field crapped out and the planet did not evolve.
Earth's field vs Mars field
The Aurora Borealis phenomenon is the collision of the suns solar wind leaking into the atmosphere where the field is the weakest. At the poles.
So why does this suck? There is something call South Atlantic Magnetic Anomaly.
The polarities seem to be reversed, which is allowing higher amounts of solar radiation into the atmosphere. The Earth apparently tends to reverse it's polarities every once in a while. The last time was 700,000 years ago. We are supposedly over due.
This is what the polarity shift would look like.
The solar wind penetration would be devastating for most species. Animals, such as bats and whales use magnetic North to travel and so all our electronics. We've obviously made it through one before, albeit barely I would imagine, so now that we know I'm sure we'll do better.
Sounds pretty rough though lol, but even at the fastest this is 1,500 years off and this is still hypothesis, but I found the evidence pretty compelling.
