An airport in Tampa, Florida, has had to temporarily close its runways to keep up with Earth’s magnetic north pole, which is drifting toward Russia at a rate of 40 miles per year.
A pole shift is sometimes confused with a pole reversal, in which the magnetic poles switch places, so that north becomes south and vice-versa. From studying the magnetism of ancient rocks, scientists have learned that pole reversals have occurred at irregular intervals throughout the Earth’s history, on average about once every 300,000 years.
The last was about 780,000 years ago. According to University of California professor Gary Glatzmaier, who has modeled the phenomenon with a supercomputer, pole reversals are the result of the movement of molten iron in the Earth’s outer core, which can cause twists in the planet’s magnetic field.
Pole reversals take place over thousands of years, during which time magnetic poles can show up in strange places — the magnetic north pole, for example, might suddenly show up on the island of Tahiti in the Pacific. Recently, some have pointed to magnetic field disturbances an area known as the South Atlantic Anomaly as a possible sign of an upcoming pole reversal — which conceivably could even occur in 2012, to the likely delight of apocalyptic believers — though scientists warn that it is not likely.
If a pole reversal did happen, according to Stanford University geophysicist Norm Sleep, it might cause some strange phenomena. Auroras would be visible at the equator instead of the poles, compasses would cease to be reliable, and radio transmissions would be adversely effected. Cosmic rays might pierce the Earth’s atmosphere more easily. Overall, though, life would still go on.
The Need for Earth-Based PEMF
Well that’s the opinion of ONE scientist. Based on the NASA zero field studies and the known need for Earth Based PEMF (Pulsed Electro-Magnetic Fields), if this event does happen in our lifetime, it would be wise to have a PEMF device like the MRS 2000.
Actually over the past 300-500 years it is known that the earth’s magnetic field has decreased by about 50%, so even if we don’t experience a polar reversal, it is still a wise investment.
