Magnetic Polar Shifts Causing Massive Global Superstorms (or not?) [View All]

Magnetic Polar Shifts Causing Massive Global Superstorms

(CHICAGO) - NASA has been warning about it…scientific papers have been written about it…geologists have seen its traces in rock strata and ice core samples…

Now "it" is here: an unstoppable magnetic pole shift that has sped up and is causing life-threatening havoc with the world's weather.

Forget about global warming—man-made or natural—what drives planetary weather patterns is the climate and what drives the climate is the sun's magnetosphere and its electromagnetic interaction with a planet's own magnetic field.

When the field shifts, when it fluctuates, when it goes into flux and begins to become unstable anything can happen. And what normally happens is that all hell breaks loose.

Magnetic polar shifts have occurred many times in Earth's history. It's happening again now to every planet in the solar system including Earth.

Pole reversal may also be initiating new Ice Age

According to some geologists and scientists, we have left the last interglacial period behind us. Those periods are lengths of time—about 11,500 years—between major Ice Ages.

One of the most stunning signs of the approaching Ice Age is what's happened to the world's precessional wobble.

Shift of Earth's magnetic North Pole affects Florida airport

A runway at Florida's Tampa International Airport is scheduled to reopen Thursday with new numbers and signage to account for the gradual shift of the Earth's magnetic North Pole.

...

Every five years, the FAA reevaluates shifts in the poles – its magnetic variation – and makes changes to runways and flight procedures as needed, Bergen said.

The FAA also publishes new aeronautical charts for pilots every 56 days, and with the next one due on Thursday, it made sense to make the changes at Tampa International Airport effective the same day, she said.

"The Earth's magnetic fields are constantly changing," she said. "It’s a very dynamic system so we make these changes effective every 56 days."

Changing magnetic poles:

Last week's big geophysical story had to do with the gradual shift of Earth's magnetic north pole away from Canada and toward Russia. The poles move because of the changing flow of molten iron in Earth's core, which drives the planet's huge magnetic dynamo. This doesn't affect Earth's spin or geographical north, but it does cause the structure of the magnetic field to shift, which affects compasses. Although a lot of navigation nowadays is done using GPS systems, the Federal Aviation Administration wants to make sure that aviators can still find their way to a safe landing using magnetic compasses — and that's why it requires airports to revise their runway designations periodically to reflect the magnetic shift.

Earth's Magnetic North Pole Is On the Move


The compass, perhaps the oldest navigational tool of man, does not point to the geographic north pole with its needle. Instead, it indicates the magnetic north pole — which, though close to the geographic north pole, is not at the “top” of the earth's axis. It is actually in the Artic Ocean north of Canada, and moves as the magnetic fields of the earth change.
The molten iron core of the spinning earth makes it a giant magnet. However, that magnetic field is actually moving. Jeffrey Love, a research scientist with the U.S. Geological Service’s Geomagnetism Program, notes: "So that means if you wait five years, the compass will be off by one degree." During some periods the drift of the magnetic north pole has been relatively slight. When it was first identified in 1831, it remained fairly stable for decades. Then, beginning in 1904, scientists began to observe a northeastern shift of about nine miles a year. Since 1989, the drift of the magnetic north pole has accelerated to about 35 miles a year in the direction of Siberia.

The earth's magnetic field also seems to be weakening. Scientists believe that in the last two centuries, the field has decreased by about five percent per century, after having remained fairly stable for the previous several centuries. Extensive and reliable information has been gleaned from centuries of sea travel. Sailors have long used compasses for navigation, and these sea voyagers have accurately recorded in their log books extensive and reliable information about the winds, tides, direction, stars and other variables. The magnetic orientation of minerals in rocks and pottery shards has also yielded clues about the planet’s magnetic field at different points in history.

The earth’s magnetic field may be in the process of reversing its polarity — something which scientists believe has happened in the distant past of the planet. Although the shift was too far back for historical records to exist, geologists are able to date lava flows to periods of planetary history, and this lava (frozen molten rock) has the same value as pottery shards in fixing the direction of magnetic fields at certain periods of time. David Gubbins, an earth scientist at the University of Leeds in Britain, ties this evidence of the decline in the strength of the planet’s magnetic field to increases of patches of reverse magnetic fields. He speculates on when this process began:
