Polar reversal already in effect
Polar reversal already in effect......caused the tsunami

Year 2012 will experience something very unique. The sun will experience a polar reversal and the earth will also experience a polar reversal. However terrestrial polar reversal takes a long process and has started already.

Polar reversal is process by which the North and South pole reverses position. According to a new study, when polar reversal is in early stage (which is now), the tectonic plates are heavily affected by the changing electro magnetic fields and the resultant change in flux characteristics affecting the gravity. During polar reversal the equilibrium between electromagnetic forces and the gravity of the earth as well as the other parts of the solar system and the galaxy is disturbed. The net effect is unpredictable erratic behavior of the continental and oceanic plates.

In the last six months, three most violent earthquakes happened in the last 150 years. This is accompanied by innumerable small quakes, under water volcanoes, mudslides and more. Simply put, the tectonic plates are slowly going out of equilibrium and are showing chaotic effects. ...cont'd

Slowing currents could cause catastrophe
01 June 2005

Powerful ocean currents are grinding slowly to a halt, raising the possibility of a catastrophic climate "flip" that could chill Europe and warm New Zealand, startling new evidence suggests.

Scientists have detected evidence of a slowdown in ocean currents that control climate across the globe, supporting earlier research on the threats of global warming.

Without these currents, parts of the globe are expected to alter dramatically. The climate in Europe would cool significantly, while New Zealand would be warmer and more susceptible to exotic diseases, scientists suggest.

The powerful ocean current system, often known as the ocean conveyor, creates a flow of warm surface water towards the North Atlantic, where it is cooled and sinks to form the circulation of cool deep-sea water throughout the world's oceans.

As part of this process, large "chimneys" of very cold water spiral to the ocean floor, playing a key role in ocean flows.

However, Cambridge University ocean physicist and Polar Ocean Physics Group head Professor Peter Wadhams has released research showing the number of these chimneys has reduced from about 12 to two as a result of global warming. ..cont'd

Snowfall in Somalia reported
Wed. June 01, 2005 10:36 am.

The first snowfall on this part of the world has claimed one life and caused extensive damage to properties. Puntland, northeastern part of Somalia has never recorded snowfall before last night when snow storms with high winds destroyed homes in Rako town.

The storm left a blanket of snow on the ground, something residents had never seen in their lives before. Aside from this unexplained snowfall on this tropical land, Somalia has experienced very strange weather in the past few months. ..cont'd

1. This could completely explain the bu$h regime.
Presenting themselves as hard-nosed skeptics, they deny climate change. But what if they are well aware of coming catastrophe such as the pole shift? For instance, they SAY there's no global warming, yet they are sure as hell mounting what APPEARS to be a countermeasure with the Chemtrails. (Yes, I realize this program began under Clinton, but consider his recent palling around with Poppy.)

It is not unreasonable to suppose that they know of a lot more Imminent Unpleasantness as well. Since its installation, the regime has operated as though there were no tomorrow. Perhaps, from what they know--and either refuse to let out or deny altogether--there really is no tomorrow!

For bu$hco, the End Of The World Scenario revolves around the collapse of giant corporations, the oil companies being first among them. Every action of the regime has the ultimate aim of increasing corporate profits. Now add the phrase "in whatever time we have left" and see if the picture does not become clearer.

SIDEBAR: There are some who see the 2012 date as fluid; we could be much closer to it than seven years.

4. It may mean the end for them. It need not be the end for us.
Pluto transiting Capricorn is going to be a very ugly time for these people... and us, too, because so many aspects of our lives depend upon government and corporate structures. Many of these institutions are going to come tumbling down or at least see dramatic changes over the next decade.

Pluto is still retrograde, backtracking towards 23 Sag, but even now, if you look and listen carefully, you can still pick up bits and pieces of what awaits us after it moves forward into Capricorn, in 2008 and thereafter.

"Coming Attractions"

Talk of Regional Government Consolidation (Cleveland and Pittsburgh) -- Older, struggling city-regions fractured by numerous suburbs and boroughs seem increasingly likely to press forward with forms of metro/consolidated government in attempts to remain viable. Where Pluto is involved, the only alternative is ruin.

Water Shortages in Colorado, "Water Wars" in the SW United States
-- We just keep right on growing, developing buildingand expanding with Pluto in Sagittarius as if there were no limits to our natural resources. That seems easy to do right now, but ignoring problems never makes them go away. What happens when the rivers and water tables are all finally tapped out? Pluto in Capricorn will force the issue, whether Americans sold on suburbia want to face it or not.

Peak Oil and the Energy Crisis
-- It could very well turn out to be the mother of all crisises in the history of humankind. Modern society was built up by use of easily extractable non-renewable resources, such as coal and oil. Most of our economic, governmental and social structures depend upon cheap oil as if it were their life's blood. It is. Could it be more than just an odd coincidence that the date of Global Peak Oil Production now falls somewhere during the year 2008? Some alternative, renewable energy sources may be ready to fly by then. But even if the OILigarchy ruling US government were to be suddenly forced out of power so that proper attention could be mobilized and devoted to a total structural overhaul, there is not enough time to complete it before the Oil Peak. Rocky and grim times lie ahead.

2. Good find Dover. The Dummies. All they had to do was look at
Pluto reaching the Galactic Center.

In all seriousness,for a second, thank you Dover. This is very important information.

This one is a surprise "The sun will experience a polar reversal "

The sun experiencing a polar reversal never entered my mind as a possibility. Then all the planets and stars in this galaxy would be experiencing a reversal - to extrapolate. We become our own alternative universe.

Snow in tropical areas?

I knew there was a reason I saved all my winter clothes.

DBT, it won't be the end of the world. Earth will go on. The poles flip every 25,000 years or so...of course no one is around to tell us
what it felt like, but I suspect Atlantis and Lemuria myths might give a clue, as do the myths of the Mayans.

Nevertheless, humans and other species survived to this date....and earth is millions of years old if not billions. Who knows.

Maybe the trick is not to be in earthquake, volcano, tsunami vulnerable areas.

Since I live 5 miles from the ocean, I have been thinking about buying one of those blow up rubber boats, even before the Xmas tsunami.

But we can't blame the polar shift on the dimbot.

On the other hand, if he plans to be in his airplane, off the earth,
I wonder if that will work, since gravity will be - well, what will it be?

Actually with a lesser gravity, we might all be able to fly or jump tall buildings - and I say that seriously...think about it.

Love reading these speculations, and appreciate your light-heatred manner here, Pallas, but this stuff creeps me out, very scary.

Guess I need to start meditating again to have a "position" to be in if/when the shit really hits the fan like this in the near future.

5. DemExpat, since there's nothing you can personally
do about it, following your own suggestions is a good idea.

Preparation as well as you can. Live every day, plan , and prepare to move through it as well as you can. Since we have no ability to turn back time, there is no choice but to move forward.

Meditating is good - but it won;t help outward preparation, unless you are meditating asking for an answer to what you should do....

Oh, I'm not kidding about the potential of jumping over tall buildings or flying. Think of the astronauts practicing in rooms made to have little gravity.

In any case, when doo doo hits the fan as you say, I find in my own case I very often just move through the event as an observer, almost as if I'm not there, but I am...

there isn't a choice, so handle whatever as well as you can.

6. Hey, Pallas!
Edited on Sun Jun-05-05 08:06 AM by dbt
I agree that Earth will go on, just as She has always done. And I do NOT believe that humans will become extinct, although we (as a whole) have certainly EARNED it. I should have copped that R.E.M. title, "the end of the world as we know it." But for people like bu$h, it will BE the end of the world. Can you imagine him trying to plant and maintain a vegetable garden, for instance?

When the long-prophecied global cooperation type of society arrives, there will be a double handful of high rollers who won't have any idea of how to function!

7. 125 Large Northern Lakes Disappear
125 Large Northern Lakes Disappear
By Robert Roy Britt

LiveScience Senior Writer
posted: 03 June 2005
02:31 pm ET

A new study finds 125 large lakes in the Arctic have vanished as temperatures rose over the past two decades. Many other lakes have shrunk.

The lakes once sat atop permanently frozen soil called permafrost. Other studies have shown permafrost is melting around the world, causing low-lying ground to slump and rock to fall from mountains.

"We think that climate warming is thawing the permafrost," said lead researcher Laurence Smith of the University of California, Los Angeles. "It's like pulling the plug out of a bathtub. There's nothing to prevent lake water from percolating through the soil to aquifers below."

Changes seem to come abruptly.

"From what we can tell from space, a lake is either just fine or it's gone," Smith said.

The sudden draining could alter entire continental ecosystems, affecting birds and other wildlife that depend on the waterways, Smith and his colleagues say. Migratory birds count on the lakes during summer to feed their young.

The research is reported today in the journal Science.

BBC - Vanishing lake baffles Russians



There have long been rumours about the lake
Residents of a village in central Russia are trying to solve the mystery of a lake that disappeared overnight.
Russia's NTV channel showed a huge, muddy basin where the lake once was, in the village of Bolotnikovo.

"It looks like somebody has pulled the plug out of a gigantic bath," said the TV's correspondent, next to a deep debris-filled hole.

Local officials in Nizhny Novgorod region say the lake was probably sucked into an underground cave.

The name of the village - which lies about 250 km (155 miles) east of Moscow - roughly translates as "boggy".

The discovery was made by local fishermen when they arrived at the lake early in the morning.

"I looked and there was no water. I thought: Oh my God, what's going on?" one of them told the TV.
Rescuers were called out to search the uncovered lake bed to see if anybody could have been sucked under, but it is thought no-one was on the lake when the waters vanished...cont'd

11. changes
Reading and seeing these changes we've brought about to Mother Earth is like a dagger to the heart. How it saddens me that we've done this when we could so easily have chosen to live another way--a way that is compatible with nature. I blame, in no small part, unbridled capitalism. That is what republicans advocate.

Has anyone here read Solviva? I'm reading the book now. It's about a woman in Massachussetts who experiments with her home to make a way of life that "does no harm."

12. I've only heard about the book from friends who do some organic
gardening.

According to them it offers some good ideas about how to use solar heating and cooling in a large greenhouse for an extended growing season, but they sort of rolled their eyes at the rambling philosophizing about 'green living' in lieu of more practical and detailed info. Speaking of "unbridled capitalism", it seemed to them that the book was more about all the money that could be made (but never was by the author)from such a system. And they felt the book itself seemed more a vehicle for cashing in on the popularity of the sustainable movement than offering substantive information and guidance.

I can't say if I'd have had the same response, but I respected their opinion and never bought the book. The area where I live is teaming with sustainability/green types, so you don't have to go far to engage in such conversations. Austin, Tx. has established itself as one of the movers and shakers in the promotion of these ideas.

13. Dover ...great post....
You know the thing about the sun reversing polarity...now that kinda hit something with me. All the flares & CME's have kept going when most of the scientists thought the 11 year cycle was at an end. It just kinda makes some sort of "truth sense" to me....

We are certainly entering times like no others that humans have been through...its all uncharted territory now for us...hard to stay out of fear too...but along with the sun and our home planet changing, so are we humans, too.

If we can stay out of fear and knowing this body is just a temporary home anyway, to be a first hand observer should be pretty cool. Maybe not easy but amazing never the less.

I do feel however that this is part of the earth- Gaia's journey to her next step and yes, we have basically soiled and messed up our own environment pretty badly, but like a good mother, she has still been trying to make her growth and transition to her next phase of "being", as gentle for us as she can, but she still has to follow her own path and if we can send love and understanding, it might help a bit..both for her and ourselves.

I do believe that planets also evolve and that is what is happening..we are all along for the ride and for our own personal evolution (ascension,eh?)

still...its quite the ride, isn't it?? life as we know it is changing for sure...and I think that may be a good thing in the long run...its getting past the short run that is the challenge....

But hey, what do I know :shrug:


:hi: everyone.... :hug: :loveya: all !!

and our intuitions, dreams, and daily experiences are informing us of these changes on many levels. All we can do is establish our own balanced centeredness and get in touch with our own purpose and journey...and trust. I've said before that I firmly believe we've all chosen to be here now for this transition...

15. Here's some more info on the SUN's polarity shift.......2012
Edited on Sat Jun-11-05 12:20 PM by Dover
I think this might just be answering all the burning questions about the many 'signs' that seem to be pointing to the 2012 time frame for significant changes occurring here on the planet...which has clearly already begun and seems to be due to the combined polarity reversals of the Sun AND Earth simultaneously...

There's plenty of evidence of this change, but we simply don't know what "life" as we've known it will be like both during this process and when the dust settles, nor how long this process will take before the earth/sun re-establish their equilibrium. As Desert Rose said above, we are charting a course thru unknown territory...

The Sun Does a Flip

NASA scientists who monitor the Sun say that our star's awesome magnetic field is flipping -- a sure sign that solar maximum is here.

February 15, 2001 -- You can't tell by looking, but scientists say the Sun has just undergone an important change. Our star's magnetic field has flipped.

The Sun's magnetic north pole, which was in the northern hemisphere just a few months ago, now points south. It's a topsy-turvy situation, but not an unexpected one.

"This always happens around the time of solar maximum," says David Hathaway, a solar physicist at the Marshall Space Flight Center. "The magnetic poles exchange places at the peak of the sunspot cycle. In fact, it's a good indication that Solar Max is really here."

The Sun's magnetic poles will remain as they are now, with the north magnetic pole pointing through the Sun's southern hemisphere, until the year 2012 when they will reverse again. This transition happens, as far as we know, at the peak of every 11-year sunspot cycle -- like clockwork.

Earth’s magnetic field also flips, but with less regularity. Consecutive reversals are spaced 5 thousand years to 50 million years apart. The last reversal happened 740,000 years ago. Some researchers think our planet is overdue for another one, but nobody knows exactly when the next reversal might occur.


Although solar and terrestrial magnetic fields behave differently, they do have something in common: their shape. During solar minimum the Sun's field, like Earth's, resembles that of an iron bar magnet, with great closed loops near the equator and open field lines near the poles. Scientists call such a field a "dipole." The Sun's dipolar field is about as strong as a refrigerator magnet, or 50 gauss (a unit of magnetic intensity). Earth's magnetic field is 100 times weaker....cont'd

Giant loops in the solar atmosphere may trigger reversals of the Sun's magnetic poles, new study reveals

BY MARK SHWARTZ

New findings by Stanford astronomers may help solve one of the most baffling questions in solar science: What causes the Sun's magnetic poles to flip-flop every 11 years?

Understanding the forces that drive this 11-year cycle could help researchers predict violent solar flares and eruptions that periodically interfere with communications on Earth, said Elena E. Benevolenskaya, a physical science research associate at Stanford's W.W. Hansen Experimental Physics Laboratory (HEPL).

"One of the main problems for astronomers in the last century has been finding a mechanism strong enough to cause polar reversals," she noted.

After analyzing a decade's worth of satellite data, Benevolenskaya and her colleagues may have found a crucial part of that mechanism -- giant loops of hot, electrified gas that link the Sun's magnetic poles to sunspots located near the solar equator.

Each loop is like a colossal, twisted rainbow -- a 500,000-mile-long arc that extends into the Sun's outer atmosphere, or corona, then returns to the surface. One end of the loop runs through either the north or south magnetic pole. The other end is connected to a sunspot of opposite magnetic polarity...cont'd

isn't it interesting that South America use to be known or seen as a darker continent much like Mexico with the oligarchs and the poor... third world countries.

Now we see the shining star of what has been democracy, freedom, success and all that people yearned for moving to that arena while SA starts to shine and lead the way for the NEW Mother Earth.

Seems to me we see the reversal in real time right before our eyes. What once was for many years is slowly fading while the light shines on those who open their hearts to Mother Earth and Spirit.

Reversal indeed! Viva la revolution!

17. Changes in the Earth's Magnetic Fields
News
April 11, 2002

Satellites Spy Changes to Earth's Magnetic Field


Though the process can take nearly 5,000 years, the earth's magnetic field periodically reverses. According to a report published today in Nature, scientists may have detected the beginning of the field's next such reversal.

Motion of the earth's liquid core, the so-called geodynamo, generates its magnetic field. Gauthier Hulot of the Institut de Physique du Globe de Paris and his colleagues used satellite data recorded 20 years apart to track changes in this field. In two regions of the boundary between the earth's core and the overlying mantle, the researchers detected a reversed magnetic field. In a section lying beneath the southern tip of Africa, the magnetic field points toward the center of the earth—opposite to the dominant outward-pointing field of the Southern Hemisphere. And a second congregation of reversed-flux patches exists near the North Pole. Having modeled the growth and movement of these inverted-flux sections, they can now account for nearly the entire decrease in the main dipole field of the earth over the past 150 years.

http://www.sciam.com/article.cfm?articleID=000C56A1-0B6...

--------------------------------------------------------------------

Magneticosphere - Earth's Magnetic Field

All magnetic objects produce invisible lines of force that extend between the poles of the object. An easy way to visualize this is to spread iron filings on a sheet of paper and place a bar magnet under the paper. The iron filings will arrange themselves around the magnet and along the magnetic field lines.

In the simplest terms, Earth can be thought of as a dipole (2-pole) magnet. Magnetic field lines radiate between Earth's north and south magnetic poles just as they do between the poles of a bar magnet. Charged particles become trapped on these field lines (just as the iron filings are trapped), forming the magnetosphere.

All magnetic objects produce invisible lines of force that extend between the poles of the object. An easy way to visualize this is to spread iron filings on a sheet of paper and place a bar magnet under the paper. The iron filings will arrange themselves around the magnet and along the magnetic field lines.

Charged particles become trapped on these field lines (just as the iron filings are trapped), forming the magnetosphere.

Earth's magnetic field lines are not as symmetrical as those of the bar magnet. The impact of the solar wind causes the lines facing sunward to compress, while the field lines facing away from the Sun stream back to form Earth's magnetotail. The magnetosphere extends into the vacuum of space from approximately 80 to 60,000 kilometers (50 to 37,280 miles) on the side toward the Sun, and trails out more than 300,000 kilometers (186,500 miles) away from the Sun.

The cause of Earth's magnetic field (the surface magnetic field) is not known for certain, but is possibly explained by dynamo theory. The magnetic field extends several tens of thousands of kilometers into space.

The field is approximately a magnetic dipole, with one pole near the geographic north pole and the other near the geographic south pole. An imaginary line joining the magnetic poles would be inclined by approximately 11.3? from the planet's axis of rotation. The strength of the field at the Earth's surface at this time ranges from less than 30 microtesla (0.3 gauss) in an area including most of South America and South Africa to over 60 microtesla (0.6 gauss) around the magnetic poles in northern Canada and south of Australia, and in part of Siberia.

The field is similar to that of a bar magnet, but this similarity is superficial. The magnetic field of a bar magnet, or any other type of permanent magnet, is created by the coordinated motions of electrons (negatively charged particles) within iron atoms. The Earth's core, however, is hotter than 1043 K, the temperature at which the orientations of electron orbits within iron become randomized. Such randomization tends to cause the substance to lose its magnetic field. Therefore the Earth's magnetic field is caused not by magnetised iron deposits, but mostly by electric currents (known as telluric currents).

DEPLETION OF THE EARTH'S MAGNETIC FIELD
- IMPACT

No. 100 October 1981
by Dr. Thomas G. Barnes

There are three important force fields associated with planet earth, a gravitational field, an electric field, and a magnetic field. The gravitational field attracts us to the earth, preventing us from flying off into space as the earth rotates. The earth's electric field is very unstable, producing electric storms from place to place and at unpredictable times.

The earth's magnetic field is due to a huge electric, current, billions of amperes, circulating in the core of the earth. But the main complication lies in the fact that there are a multitude of extraneous sources which produce distortions in the magnetic field. As a consequence, the earth's magnetic field is very complex. The instability sometimes shows up as tremendous magnetic storms, blocking out transoceanic radio transmissions. There are all kinds of anomalies resulting from distortions in the magnetic field. There are many unpredictable variations in the magnetic field with time and location.

Navigators do not depend on their magnetic compass as much now as in early days. When navigators do use the magnetic compass they have up-dated magnetic charts to provide corrections for gross deviations in the earth's magnetic field from place to place over the globe. This helps them correct their bearings for "false" directions indicated by the compass, but the charts can not correct for all the distortions.
