EARTH´S MAGNETIC POLE FLIP

The Earths magnetic field, the protector of all life on Earth is under constant attack from deadly cosmic radiation. This invisible shield that we live in is weakening in a region over the South Atlantic, leaving it exposed to potentially lethal radiation. Is the Earth losing its magnetic field and doomed to a fate similar to Mars? Many scientists believe the answer lies in paleomagnetic data, and that this weakening may be a precursor to a magnetic field reversal; scientists know Earth is long overdue. However, humans were not around when the last reversal took place, so what does this mean for life? [Sarah Livesey via YouTube]
