Earth’s Magnetic Field May Not Flip – Matter Of Relief Or Concern?
Short Bytes: A recent study shows that Earth’s magnetic field may not flip in the near future. Over the last 200 years, Earth’s magnetic field has weakened at an alarming rate of 15%. This may result not only in the distortion of power grid and satellite communications, but also punched holes into the Earth’s ozone layer, thereby increasing cancer rates.
What follows would be a global cataclysm where continents would sway to one side, giving rise to floods and earthquakes and so on. However, a recent study shows that Earth’s magnetic field may have been rather approaching a normal limit.
So is that a good thing or bad?
Well, while most of us would feel relieved about the fact that the Earth’s magnetic field may have been coming down to a normal range, rather than approaching a pole reversal – but then the other side to the coin being that gradually weakening magnetic fields would seriously impede power grid and satellite communications.
Over the last 200 years, the Earth’s magnetic field has weakened at an alarming rate of 15%. This escalating rate of weakening may further cause solar winds to punch holes into the Earth’s ozone layer, thereby increasing cancer rates.
While database calculation is suggestive of the long-term average intensity over the past five million years being similar to the field’s intensity today, a counter theory still exists of the Earth’s poles undergoing a reversal in the next 100 years.
