Magnetic Reversals

Scientists tell us that our magnetic poles have reversed in the past, and that they will again. The last one occurred 780,000 years ago. The average time period between reversals is 450,000 years, but there isn’t really any pattern, it is random. We are overdue by average only.

Scientists don’t really know how the process works, and are unable to predict the next reversal. They have been telling us that the process takes hundreds or thousands of years. Recent studies have shown that it can happen in the space of weeks or months, and I suggest it can happen overnight. Perhaps rapid reversals don’t leave much evidence – perhaps rapid reversals are quite common! For example, if it was normal for a double reversal to happen quickly – where the poles return to their original position – we wouldn’t know about any historical instances.

If a reversal involves a dramatic lessening of our geomagnetic field’s strength, then basically our shields are down, and cosmic rays reaching ground-level will greatly increase. Forget about navigational problems – we could be fried.

Pigeons

Studies have shown that pigeons have receptors in their brains that are sensitive to magnetic fields, and presumably those are a reason for their great navigation skills. It is possible that many other animals also have such receptors, but they don’t utilize them as obviously. So during a reversal, the chaos in the animal world could be significant – and of course humans are animals.

Possible Triggers

Scientists have not yet worked out what causes a magnetic reversal, but recent studies of Mercury suggest that the solar wind and particles from the Sun have an effect on planetary cores. My interpretation is that a massive solar storm could be the straw that breaks the camel’s back and trigger a reversal if the Earth is ready for one. The Electric Universe folk have also suggested that a highly-charged comet passing by could also do the trick. Or perhaps ocean currents, after being affected by climate change, are the trigger? And if climate change is caused by the Sun, then that ties in nicely with the first theory.

Another theory comes from  Rich Muller:

where “lighter components, like oxygen, sulfur, and silicon . . . rise toward the core-mantle boundary (CMB).” Accumulating like sediment on the floor of the ocean, these “fall” upward from the core onto the surface of the mantle, which is uneven like the topography of the Earth’s surface. When enough sediment collects, it tumbles like an avalanche, into the outer core, thereby cooling it.

Rare events could trigger really big avalanches at the CMB, however. When a massive asteroid or comet slammed into Earth’s surface at an oblique angle, the lower mantle would jerk sideways, shearing off whole mountains of sediment. As the sediments slide up, a downward-sinking mass of cool iron could completely disrupt large convection cells. Although variously oriented local fields within the core would remain strong, at the surface Earth’s dipole magnetic field would collapse.

And according to Gary Glatzmaier reversals are rooted in chaos theory:

The resulting three-dimensional numerical simulation of the geodynamo, run on parallel supercomputers at the Pittsburgh Supercomputing Center and the Los Alamos National Laboratory, now spans more than 300,000 years.

Our solution shows how convection in the fluid outer core is continually trying to reverse the field but that the solid inner core inhibits magnetic reversals because the field in the inner core can only change on the much longer time scale of diffusion. Only once in many attempts is a reversal successful, which is probably the reason why the times between reversals of the Earth’s field are long and randomly distributed.

 

Rapid Magnetic Changes

NASA loves telling is that a magnetic reversal takes thousands of years, and that we have nothing to fear. I suggest that NASA should pay more attention to scientific studies that suggest otherwise:

…a new study of ancient copper mines in southern Israel found that the strength of the magnetic field could double and then fall back down in less than 20 years. [Wired]

 

This lava, Bogue says, initially started to cool and then was heated again within a year as a fresh lava flow buried it. The fresh lava re-magnetized the crystals within the rock below, causing them to reorient themselves a whopping 53 degrees. At the rate the lava would have cooled, says Bogue, that would mean the magnetic field was changing direction at approximately 1 degree per week. [Wired]

 

Palaeomagnetic results from lava flows recording a geomagnetic polarity reversal at Steens Mountain, Oregon suggest the occurrence of brief episodes of astonishingly rapid field change of six degrees per day. The evidence is large, systematic variations in the direction of remanent magnetization as a function of the temperature of thermal demagnetization and of vertical position within a single flow, which are most simply explained by the hypothesis that the field was changing direction as the flow cooled. [Nature]

 

the spacing in time between successive flows erupted during a transition cannot be determined accurately because the errors associated with radiometric ages are typically much greater than the duration of a polarity transition. [The Magnetic Field of the Earth: Paleomagnetism, the Core, and the Deep Mantle, page 205]

The final quote suggests that we are not able to detect rapid transitions, and that estimates of durations lasting thousands of years are are a consequence of measurement limitations.

Accelerating

This is indisputable – the speed at which the magnetic north pole is moving (not necessarily in the same direction) has recently become much faster. Because this is the entirety of our studies, we don’t know what was normal prior to the 1500s…

Not only are the poles moving rapidly – the strength of our magnetic field is diminishing as well:

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 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. [National Geographic]

 

The Navigational Danger

Without our magnetic shield, technology will be more at risk from solar storms. The most at risk will be satellites – they are not designed to withstand solar storms in the absence of the magnetic field. So if our GPS satellites are knocked out, planes would be grounded.

Of course planes have old-school compasses as a backup, but these certainly will not be accurate during a magnetic pole shift. So even the possibility of GPS satellites failing would be enough to ground planes – otherwise they could lose navigation mid-flight.

Ships would face the same problems of course.

The Ozone Danger

It is expected that the Ozone Layer would disappear completely during a magnetic reversal (and return afterwards). See this NASA paper, Particle Events as a Possible Source of Large Ozone Loss during Magnetic Polarity Transitions.

Major solar storms during a reversal could cause ozone depletion. According to Wikipedia, humans would see at least 3x more incidences of skin cancer. The effects on all living things combined is hard to predict, but could be catastrophic when everything is added together.

The Power Grid Danger

One study has nominated massive solar storms as the trigger for a magnetic reversal. Another suggests global warming is the culprit – and global warming can be caused by increased solar activity. During a reversal our shields are down, and if there is a concurrent solar storm, the situation becomes worse again. Life on Earth won’t be affected in general, and societies that don’t rely on technology will be OK as well. The most modern societies would suffer terribly if the reversal is rapid. Power grids would fail (a major solar storm can wreck them, and a magnetic reversal would be much worse). With no electricity there is no water, no sewage being pumped, no gas stations operating, no deliveries of food. Emergency services will be compromised and unable to make much of a difference. Certainly millions would die, and a billion people would face great difficulties. Only those who have sensibly prepared by storing food and water will be able to cope.

The Cosmic Ray Danger

Detailed calculations confirm that, if the Earth’s dipole field disappeared entirely (leaving the quadrupole and higher components), most of the atmosphere could be reached by high energy particles. However, the atmosphere would stop them. Instead there would be secondary radiation of 10Be or 36Cl from collisions of cosmic rays with the atmosphere. There is evidence that this occurs both during secular variation and during reversals. [Wikipedia]

Our geomagnetic field is responsible for blocking out roughly 50% of cosmic rays [Nature]… so if our “shields are down”, cosmic radiation would double. While this would lead to increased mutations, double the current rate is nothing to worry about. However, two of the possible triggers for a magnetic pole shift are a result of increases in solar activity. This could result in an increased in charged particles from the Sun reaching Earth as well. And that could spell trouble.

  1. Thanks for the information on this site. In the scenario where the dipole field disapears and solar particles and cme’s are earth directed, how long do you think we would be in that vunerable position for? Days, weeks, months? Also, where is magnetic north now?

    • Nobody knows how long a magnetic pole shift will take. If it is rapid (days, weeks) then it is expected that the dipole will be gone for that period. If it takes decades, then the shift could be so gradual that we stay safe. But nobody fully knows how this all works, so it is best to expect the worst.

  2. I simply wana in this tym no öne would be who do wrong things to humaninty the person’s would face real threat and the person’s meditating would only be saved and after this pole shift there would be a golden period in which there would’nt be any wrong things done ! And i to am waitin for that golden period ! My waheguru would save all the person’s who meditates him and all others would be finished in a blink of eye ! And one thing more please start meditating if u realy wana save ur lyf ! That’s it and waheguru ji ka khalsa waheguru ji ki fateh

  5. I tried to register but got stuck on the question about water, I tried boiled, purified, filtered, stored but none of those worked. I do however have some information I would like to share. lately my ears have been killing me, there is a massive increase in pressure. I can’t sleep well and have been getting some profound insights. there will be a period of instability. It will speed up as you stated, there will be geographic anomolies and different parts of the world will experience several blasts of magnetic anomolies. similar to that of the sun and its flairs but in magnetic form meaning like the video you just posted of Arizona, lighting storms, wind storms, ice storms in freak and sudden places. getting worse and worse but as fast it happens it will slow again to almost normal… but the sun will not rise in the west… what you will see however is the continents slowly changing direction instead of them gradually moving west to east, they will start moving more rapidly from east to west then slowing again. the continents that are closer to the equator will move the fastest. I would expect massive amounts of volcanic activity as well. keep in mind volcanic islands do not move unless something else acts upon them like another continent. to prove this correct, which I already know is. get good core and soil samples from the british isles dead volcanic craters and see if the debris that created them came from icelands volcanic funnels. iceland just grew a new island similar to hawaii. but the british isles are closer to iceland so therefore distance being shortend will be easier to measure. I suggest you keep a diary to pass on to your children and their children… there are not enough ancient records kept due to conflict between rival powers and your computer will be obsolete.. seems too many in the past destroyed really good resources that we could have used today, lets hope the next generation of civilization learns peace. Meditate. the answers are there if you open yourself up to listen.

  6. WHY THERE IS GLOBAL WARMING

    People in the USA, are being told by the U.S. government and media that global warming is man-made. If that is true, how can the government and media explain the high temperatures the earth has experienced in past years when there were far fewer people? Let us look back in the world’s history: for example, between roughly 900AD and 1350AD the temperatures were much higher than now. And, back then there were fewer people, no cars, no electric utilities, and no factories, etc. So what caused the earth’s heat? Could it be a natural occurrence? The temperature graph at the bottom of this article shows the temperatures of the earth before Christ to 2040.

    In the book THE DISCOVERERS published in February 1985 by Daniel J. Boorstin, beginning in chapter 28, it goes into detail about Eric the Red, the father of Lief Ericsson, and how he discovered an island covered in green grass.

    In approximately 983AD, Eric the Red committed murder, and was banished from Iceland for three years. Eric the Red sailed 500 miles west from Iceland and discovered an island covered in GREEN grass, which he named Greenland. Greenland reminded Eric the Red of his native Norway because of the grass, game animals, and a sea full of fish. Even the air provided a harvest of birds. Eric the Red and his crew started laying out sites for farms and homesteads, as there was no sign of earlier human habitation.

    When his banishment expired, Eric the Red returned to congested Iceland to gather Viking settlers. In 986, Eric the Red set sail with an emigrant fleet of twenty-five ships carrying men, women, and domestic animals. Unfortunately, only fourteen ships survived the stormy passage, which carried about four-hundred-fifty immigrants plus the farm animals. The immigrants settled on the southern-west tip and up the western coast of Greenland.

    After the year 1200AD, the Earth’s and Greenland’s climate grew colder; ice started building up on the southern tip of Greenland. Before the end of 1300AD, the Viking settlements were just a memory. You can find the above by searching Google. One link is:

    The following quote you can also read about why there is global warming. This is from the book EINSTEIN’S UNIVERSE, Page 63, written by Nigel Calder in 1972, and updated in 1982.

    “The reckoning of planetary motions is a venerable science. Nowadays it tells us, for example, how gravity causes the ice to advance or retreat on the Earth during the ice ages. The gravity of the Moon and (to a lesser extent) of the Sun makes the Earth’s axis swivel around like a tilted spinning top. Other planets of the Solar System, especially Jupiter, Mars and Venus, influence the Earth’s tilt and the shape of its orbit, in a more-or-less cyclic fashion, with significant effects on the intensity of sunshine falling on different regions of the Earth during the various seasons. Every so often a fortunate attitude and orbit of the Earth combine to drench the ice sheets in sunshine as at the end of the most recent ice age, about ten thousand years ago. But now our relatively benign interglacial is coming to an end, as gravity continues to toy with our planet.”

    The above points out that the universe is too huge and the earth is too small for the earth’s population to have any effect on the earth’s temperature. The earth’s temperature is a function of the sun’s temperature and the effects from the many massive planets in the universe, i.e., “The gravity of the Moon and (to a lesser extent) of the Sun makes the Earth’s axis swivel around like a tilted spinning top. Other planets of the Solar System, especially Jupiter, Mars and Venus, influence the Earth’s tilt and the shape of its orbit, in a more-or-less cyclic fashion, with significant effects on the intensity of sunshine falling on different regions of the Earth during the various seasons.”

    Read below about carbon dioxide, which we need in order to exist. You can find the article below at:

    http://www.geocraft.com/WVFossils/ice_ages.html.
    FUN FACTS about CARBON DIOXIDE.

    Of the 186 billion tons of carbon from CO2 that enter earth’s atmosphere each year from all sources, only 6 billion tons are from human activity. Approximately 90 billion tons come from biologic activity in earth’s oceans and another 90 billion tons from such sources as volcanoes and decaying land plants.

    At 380 parts per million CO2 is a minor constituent of earth’s atmosphere–less than 4/100ths of 1% of all gases present. Compared to former geologic times, earth’s current atmosphere is CO2- impoverished.

    CO2 is odorless, colorless, and tasteless. Plants absorb CO2 and emit oxygen as a waste product. Humans and animals breathe oxygen and emit CO2 as a waste product. Carbon dioxide is a nutrient, not a pollutant, and all life– plants and animals alike– benefit from more of it. All life on earth is carbon-based and CO2 is an essential ingredient. When plant-growers want to stimulate plant growth, they introduce more carbon dioxide.

    CO2 that goes into the atmosphere does not stay there, but continuously recycled by terrestrial plant life and earth’s oceans– the great retirement home for most terrestrial carbon dioxide.

    If we are in a global warming crisis today, even the most aggressive and costly proposals for limiting industrial carbon dioxide emissions and all other government proposals and taxes would have a negligible effect on global climate!

    The government is lying, trying to use global warming to limit, and tax its citizens through “cap and trade” and other tax schemes for the government’s benefit. We, the people cannot allow this to happen.
