On January 26th 2018, Undark.org posted an excerpt from a book written by science journalist Alanna Mitchell, that make the case for a shift of the Earth's magnetic poles. She says that the magnetic poles shift or flip once every 200,000 to 300,000 years, and that we are over due as one hasn't happen for nearly 780,000 years. The Earth's magnetic field protects our planet from harmful solar and cosmic radiation by deflecting high energy particle off into space.
According to Ms. Mitchell readings from the European Space Agency's SWARM satellite system, which were launched in 2013, coupled with data from Germany's CHAMP satellite were used by researchers to take measurements of the Earth's crustal magnetization. Their findings help them to discover that the Earth's magnet field is in a permanent state of flux. They also learned that the earth's magnetic field tried to shift but failed about 40,000 years ago.
If a pole shift were to occur in the not to distant future, it could be very bad for life on Earth. Scientists haven't been able to determine when a pole reversal would take place. They do however, believe that pole shifts happen slowly and could possibly take anywhere from a couple of months to thousands of years. During a pole shift, our planet would be left unprotected and the ozone layer depleted. High energy particles and ultra violet rays would not only damage our electrical systems but could also cause man to go the way of the Dinosaurs.
