So I watched The Universe (History Channel self shaming) and was slightly alarmed at the prospect of Earth becoming Mars like should we lose our
Nasa tells us we don't need to worry that Magnetosphere reversal is so common over the billions of years. We are apparently well overdue having been
over 800 000 years since the last one. When on average it has taken place every 200-400K years.
Here is what Nasa says regarding no disruption to earths biology with planetary field changes.
The last time that Earth's poles flipped in a major reversal was about 780,000 years ago, in what scientists call the Brunhes-Matuyama reversal. The
fossil record shows no drastic changes in plant or animal life. Deep ocean sediment cores from this period also indicate no changes in glacial
activity, based on the amount of oxygen isotopes in the cores. This is also proof that a polarity reversal would not affect the rotation axis of
Earth, as the planet's rotation axis tilt has a significant effect on climate and glaciation and any change would be evident in the glacial record.
Comforting slightly, but tell that to Mars. Once with flowing water and likely ancient life, when it lost its Magnetosphere and the planet pretty much
died when solar winds started stripping away Mars atmosphere.
Now I'm not actually at Defcon 1 Doomsday status in regards to a solar storm killing us when the poles shift. I don't think it will as I don't think
it will happen at once , But my thoughts are this;
The fossil record shows no great biological change which is great, but life on earth did not rely on electricity as we do now. Will the process of
reversal leave us a damaged magnetosphere for a period of days long enough to cause a magnet apocalypse that wipes out our infrastructure that relies
so heavily on Electricity?
North is moving over 45 miles a year when just at the beginning of the 20th century it was at a static 10 miles a year. Is the change coming?
