Earth 'overdue' for magnetic pole reversal

Earth's magnetic field may be about to reverse, which could have devastating consequences for humanity.Scientists think that Earth is long "overdue" for a full magnetic reversal and have determined that the magnetic field's strength is already declining by 5 percent each century. This suggests that a fully reversal is highly probable within the next 2,000 yearsEarth's magnetic field surrounds the planet and deflects charged particles from the sun away, protecting life from harmful radiation.
