A reversal in Earth’s magnetic field thousands of years ago plunged the planet into an environmental crisis that may have resembled “a disaster movie,” scientists recently discovered.
Our planet’s magnetic field is dynamic and, numerous times, it has flipped — when the magnetic North and South Poles swap places. In our electronics-dependent world, such a reversal could seriously disrupt communication networks.
