Earth's Core, Magnetic Field Changing Fast, Study Says

Rapid changes in the churning movement of Earth's liquid outer core are weakening the magnetic field in some regions of the planet's surface, a new study says.

"What is so surprising is that rapid, almost sudden, changes take place in the Earth's magnetic field," said study co-author Nils Olsen, a geophysicist at the Danish National Space Center in Copenhagen.

The findings suggest similarly quick changes are simultaneously occurring in the liquid metal, 1,900 miles (3,000 kilometers) below the surface, he said.

The swirling flow of molten iron and nickel around Earth's solid center triggers an electrical current, which generates the planet's magnetic field.

The study, published recently in Nature Geoscience, modeled Earth's magnetic field using nine years of highly accurate satellite data.

Flip-Flop

Fluctuations in the magnetic field have occurred in several far-flung regions of Earth, the researchers found.

In 2003 scientists found pronounced changes in the magnetic field in the Australasian region. In 2004, however, the changes were focused on Southern Africa.

The changes "may suggest the possibility of an upcoming reversal of the geomagnetic field," said study co-author Mioara Mandea, a scientist at the German Research Centre for Geosciences in Potsdam.

Earth's magnetic field has reversed hundreds of times over the past billion years, and the process could take thousands of years to complete.

The decline in the magnetic field also is opening Earth's upper atmosphere to intense charged particle radiation, scientists say.

Satellite data show the geomagnetic field decreasing in the South Atlantic region, Mandea said, adding that an oval-shaped area east of Brazil is significantly weaker than similar latitudes in other parts of the world.

"It is in this region that the shielding effect of the magnetic field is severely reduced, thus allowing high energy particles of the hard radiation belt to penetrate deep into the upper atmosphere to altitudes below a hundred kilometers (62 miles)," Mandea said.

This radiation does not influence temperatures on Earth. The particles, however, do affect technical and radio equipment and can damage electronic equipment on satellites and airplanes, Olsen of the Danish space center said.

Keep Watching

The study documents just how rapidly the flow in Earth's core is changing, said Peter Olson, a geophysics professor at Johns Hopkins University in Baltimore, Maryland, who was not involved with the research.

By using satellite imagery, researchers have a nearly continuous measurement of changes, he said.

"They provide a good rationale to continue this monitoring longer," Olson said

Warning::St0ckmarket Crash Part Two

My readers will know that i have been warning about a crash in both the stock markets and the economy since early this year. From my previous post in march 08 i warned of a crash. I am here this evening to tell you the worst is not over, it can begin as early as tomorrow, Thursday Nov 20th 2008. Today we closed below 8,000 on the Dow for the first time in three years. This is the message the mainstream media is pumping out to the block heads. What the MSM is leaving out is the October crash low of 7,773.71. We closed today at 7,997.28, roughly 200 points from the crash low. Everyone with half a block head knows is a crucial level.

As i write this the Nikkie is down -304.74 or -3.68%.
Odds are this sell of will continue into the morning.

With so many horrible situations (fundamental, financial ticking time bombs detailed in my previous crash post) i must ask, is this it? Is this the simultaneous economic/market/currency crash i have been warning of? Is this the beginning of our new U.S. currency or even worse a new global currency?

Many of you think the worst is over, the bottom is in. I have news for you block head, you have not felt enough pain. Your not in enough pain to give up your financial sovereignty. This is why the worst is yet to come.

When we hit our october crash low the market was clearly oversold as indicated on my chart below. When we hit this low again we will not be oversold as seen in the relative strength section of the chart. You will also see the macd crossover and other technicals are leading to a new, solid down trend.
