Barcode magnetic record
Who among us in our youth did not regret that our thoughts and momentary actions pass without a trace? And who has not dreamed of magical tablets, similar to the biblical stone tablets given by God to Moses on Mount Sinai, which can forever preserve the memory of us?
Let's look around and ask ourselves: the surrounding rocks - is it not in them that the history of the Earth is written on grains of ferromagnetic materials that retain magnetization for millions of years, starting from the moment when the rock ceased to be fiery lava? After all, the magnetic field is the only field known in physics that has a memory: at the moment when the rock cooled below the Curie point - the temperature at which magnetic order is achieved, it became magnetized under the influence of the Earth's field and forever imprinted its configuration at that moment. Is it only rocks that are capable of preserving the memory of magnetic emanations (outflows) that accompany any event both in the life of the planet and in the biography of an individual being?
Extracting this rich and varied information is a rewarding task for future researchers. Modern paleomagnetologists, lest my colleagues bear grudges against me, usually limit themselves to studying the evolution of the magnitude and direction of remanent magnetization. However, even such an essentially elementary approach allows us to draw a very important conclusion for earthly civilization about the consequences of the expected inversion of the geomagnetic field. Research by paleomagnetologists, in particular at the Institute of Physics of the Earth named after. O.Yu. Schmidt RAS, allowed us to trace the history of changes in the Earth’s field over 3.5 billion years and build a kind of barcode, a calendar of inversions. It shows that they occur quite regularly, 3-8 times per million years, but the last one happened on Earth as much as 780 thousand years ago, and such a deep delay in the next event is very alarming.
“They’re scaring me again,” the reader sighs. “The end of the world, a comet strike, nuclear winter, terrorism, extremism, and now an inversion!” For some reason I remembered Anna Akhmatova: “The end of the world has already come, but no one noticed it.” But how can one not notice the fleeting reversal of the Earth’s magnetic field? The subsolar side of the magnetosphere, which is restrained by the ropes of magnetic field lines frozen into the proton-electron near-Earth plasma, will lose its former elasticity, and a stream of deadly solar and galactic radiation will rush to the Earth. There’s no way this won’t go unnoticed.
About the source of the geomagnetic field
Throughout its history, the Earth has changed the position of its magnetic poles many times. The picture on the left shows a fragment of a giant barcode, where alternating gray and black stripes correspond to a change in poles. The numbers on the left are millions of years. Rarely a work on geomagnetism is complete without mentioning the treatise of William Gilbert, the court physician of Queen Elizabeth I of England, “On the Magnet, Magnetic Bodies and the Great Magnet - the Earth,” which was published in 1600. It shows that the Earth’s magnetic field is the same as that of a magnetic dipole, that is, our planet is like a large magnetic needle. Introducing the last book of his famous treatise with parting words, Gilbert wrote: “Now we must reveal the reasons and the surprising, although previously noticed, but unexplained actions of all this.”
400 years later, Gilbert's words still remain relevant. The mystery of geomagnetism has not yet been solved and remains one of the most important unresolved fundamental problems of geophysics.
It would be wrong to believe that geomagnetologists have slept peacefully for four centuries. From the 17th to the 20th centuries, a huge number of observations were made of magnetic field Earth, as a result of which the basic patterns of its behavior were revealed. It is impossible not to note the enormous contribution of such famous scientists as Halley Halley, Alexander von Humboldt, Joseph Gay-Lussac, James Maxwell, Carl Gauss.
Particularly significant is the creation of the theory of electromagnetism by Maxwell in the 70s of the 19th century. From his equations it follows that the magnetic field is generated by electric current. Further, this implies the equivalence of closed elementary currents and magnetic dipoles, the moment of which is also called the magnetic moment of the current. Adding up, these quantities form, for example, the magnetic field of a cylindrical magnet, which approximately coincides with the field of a solenoid of the same length and the same cross-section. To those readers who remember the school textbook on physics by A.V. Peryshkin, I simply remind the common truths. I don’t undertake to answer for the young tribe.
Now, moving on to the “big magnet,” at first glance it seems like a small task: to find current systems inside the planet of a suitable configuration and forces that create a field on the Earth’s surface, the structure of which we have studied well.
If we move inside the Earth, then, after passing through the crust (0-15 km under the oceans and 0-50 km under the continents), the upper mantle (up to 640 km deep) and the lower mantle (640-2885 km), we will find ourselves in a huge liquid core ( 2885-4590 km), the existence of which was established in the mid-20th century by Harold Jeffreys of the University of Cambridge. It is the liquid state of a significant part of the core that explains the mechanism of geomagnetic field generation. Its essence is that the Earth's constant magnetic field is determined by electric currents arising from the movement of a conducting fluid in the core. An alternative to this theory has not yet been invented.
If we go further and try to understand the essence of the processes of generating the Earth’s geomagnetic field, then it’s time to involve the dynamo mechanism for this purpose. In rough terms, we will assume that the creation of a magnetic field in the outer liquid core of the Earth occurs in the same way as in a self-excited dynamo, where a coil of wires rotates in an external magnetic field. Then due to electromagnetic induction An electric current arises in the coil and creates its own magnetic field. It strengthens the external magnetic field, and the current in the coil also increases.
Rice. 1. The strength of the Earth’s magnetic field drops at an increasing rate during the observation period.
Of course, the planet's liquid core is not a dynamo. But if thermal convection occurs in a liquid conductor, then a certain system of flows of electrically conductive liquid appears, which is similar to the movement of the conductor. It would not be a gross violation of nature to assume that there are some basic magnetic fields in the core. This means that when the liquid conductor is at its relative motion(and this is due to the fact that the core does not rotate at the same speed as the crust) crosses the field lines of these fields, then an electric current arises in it, creating a magnetic field that enhances the external seed field, and this, in turn, intensifies the electric current and so on, like a song about a priest and his dog who carelessly ate a piece of meat. The process will continue until a stationary magnetic field is established, when various dynamic processes balance each other.
The ideas presented for the source of the geomagnetic field are called hydromagnetic dynamo (HD) and were first expressed in 1919 by Joseph Larmore in England to explain solar magnetism. In the mid-40s, Ya.I.Frenkel in the USSR and Walter Elsasser in the USA suggested that thermal convection in the core is precisely the reason that activates the HD of the Earth's core.
However, the GD theory (more correctly, it is still a hypothesis, since no one has yet been able to obtain experimental evidence) is not so flexible as to explain the whole variety of observed facts related to geomagnetism. This is not the place to present the tricks and stretches with which experts try to combine the incompatible. Sometimes the simplest fairy-tale hypothesis seems more convincing: in the depths of the planet sits a devil with horns and spins a huge linear magnet, causing anomalies in the geomagnetic field.
Signs of an impending inversion
Since the theory is dragging along in the wagon train, let's turn to the facts. And the facts indicate that throughout the history of the Earth, the geomagnetic field has repeatedly changed its polarity. There were periods when reversals occurred several times per million years, and there were periods of long calm when the magnetic field retained its polarity for tens of millions of years.
Rice. 2. Drift of the Earth's North Magnetic Pole for the period since 1931.
According to the results of studies of the laboratory of the main geomagnetic field and petromagnetism of the Institute of Physics of the Earth named after. O.Yu.Schmidt RAS, the frequency of inversions in the Jurassic period and in the Middle Cambrian was one inversion every 200-250 thousand years. However, the last inversion took place on the planet 780 thousand years ago. From this we can draw a cautious conclusion that another inversion should occur in the near future. Several considerations lead to this conclusion. Palaeomagnetism data indicate that the time during which magnetic poles The lands change places during the inversion process, not very much. The lower estimate is one hundred years, the upper estimate is eight thousand years. A mandatory sign of the onset of inversion is a decrease in the geomagnetic field strength, which decreases tens of times compared to the norm. Moreover, his tension can drop to zero, and this state can last for quite a long time, decades, if not more. Another sign of inversion is a change in the configuration of the geomagnetic field, which becomes sharply different from the dipole one. Are these signs present now? It seems so.
The behavior of the Earth's magnetic field in relatively recent times is helped by data from archaeomagnetic studies. Their subject is the residual magnetization of shards of ancient ceramic vessels: magnetite particles in baked clay fix the magnetic field while the ceramics are cooling. These data indicate that over the past 2.5 thousand years, the geomagnetic field intensity has been decreasing. At the same time, observations of the geomagnetic field at the global network of observatories indicate an accelerated decline in its strength in recent decades (Fig. 1).
Another interesting fact- change in the speed of movement of the Earth's magnetic pole. Its movement reflects processes in the outer core of the planet and in near-Earth space. However, if magnetic storms in the Earth's magnetosphere and ionosphere cause only relatively small jumps in the position of the pole, then deep factors are responsible for its slow but constant displacement.
As can be seen in Fig. 2, Since its discovery by D. Ross in 1931, the North Magnetic Pole has been moving at a speed of 10 km per year in a northwesterly direction for half a century. However, in the 80s, the displacement rate increased several times, reaching an absolute maximum of about 40 km/year by the beginning of the 21st century: by the middle of this century it could leave Canada and end up off the coast of Siberia. The sharp increase in the speed of movement of the magnetic pole reflects the restructuring of the system of current flows in the outer core, which is believed to create a geomagnetic field.
The strongest argument
Configurations of the planet's magnetic field during the period of inversion (according to G. Glatzmaier and P. Roberts).
Rice. 3. Change 
As you know, to prove a scientific position, you need thousands of facts, but to refute it, just one is enough. The arguments presented above in favor of inversion only suggested the possibility of an impending doomsday.
The strongest indication that the reversal has already begun comes from recent observations from the European Space Agency's Ørsted and Magsat satellites. Their interpretation, carried out by Gauthier Ilo of the Paris Institute of Physics of the Earth, showed that the magnetic field lines on the outer core of the Earth in the South Atlantic region are located in the opposite direction to what they should be in the normal state of the field. But the most interesting thing is that the anomalies of the field lines are very similar to the data from computer modeling of the geomagnetic inversion process performed by Californian scientists Harry Glatzmeier and Paul Roberts, who created the most popular model of terrestrial magnetism today (Fig. 3).
So, here are four facts that indicate an approaching or already begun geomagnetic field reversal:
1. A decrease in geomagnetic field strength over the past 2.5 thousand years;
2. Acceleration of the decline in field strength in recent decades;
3. Sharp acceleration of the magnetic pole displacement;
4. Features of the distribution of magnetic field lines, which becomes similar to the picture corresponding to the stage of inversion preparation.
Start of inversion:
Zones of inversely directed magnetic field begin to appear.
ABOUT possible consequences There is a wide debate about the change of geomagnetic poles. There are a variety of points of view - from quite optimistic to extremely alarming. Optimists refer to the fact that geological history Hundreds of inversions have occurred on Earth, but mass extinctions and natural disasters have not been linked to these events. In addition, the biosphere has significant adaptability, and the inversion process can last quite a long time, so there is more than enough time to prepare for the changes.
The opposite point of view does not exclude the possibility that an inversion may occur within the lifetime of the next generations and will prove to be a disaster for human civilization. In particular, several years ago, the Canadian popular science magazine Discovery magazine compiled a list of the twenty greatest dangers, where inversion is listed as number six.
Transformation of a dipole into a multipole: in addition to funnels in the region of the poles, funnels are formed in the equator region; along them, charged particles from the Sun easily reach the atmosphere, causing auroras in the tropics.
It must be said that this point of view is largely compromised by a large number of unscientific and simply anti-scientific statements. An example is the view that during an inversion human brains will experience a reboot, similar to what happens with computers, and the information contained in them will be completely erased. Despite such rather anecdotal statements, I dare say that the optimistic point of view is very superficial. Modern world- far from what it was hundreds of thousands of years ago: man has created many problems that have made this world fragile, easily vulnerable and extremely unstable. There is reason to believe that the consequences of the inversion will indeed be truly catastrophic for world civilization. And the complete loss of functionality of the World Wide Web due to the destruction of radio communication systems (and this will certainly occur at the time of the loss of radiation belts) is just one example of a global catastrophe. In fact, with the upcoming inversion of the geomagnetic field, we must experience a transition to a new space. The study of possible risks associated with inversion is actively being carried out in the laboratory of the Institute of Physical Sciences, headed by Candidate of Physical and Mathematical Sciences V.E. Pavlov.
Reverse field state after inversion.
An interesting aspect of the impact of geomagnetic inversion on our planet, associated with a change in the configuration of the magnetosphere, is considered in his recent works by Professor V.P. Shcherbakov from the Borok Geophysical Observatory. In the normal state, due to the fact that the axis of the geomagnetic dipole is oriented approximately along the Earth's rotation axis, the magnetosphere serves as an effective screen for high-energy flows of charged particles moving from the Sun. During an inversion, it is quite possible that a funnel will form in the frontal subsolar part of the magnetosphere in the region of low latitudes, through which solar plasma can reach the Earth’s surface. Due to the rotation of the Earth in each specific place of low and partly moderate latitudes, this situation will repeat every day for several hours. That is, a significant part of the planet’s surface will experience a strong radiation impact every 24 hours.
There is reason to believe that a significant drop in magnetic field strength and a change in its configuration can have significant, even catastrophic, consequences for the climate. In this regard, however, we need to define what we understand by climate disasters. The famous Soviet geologist D.V. Nalivkin noted: that on the scale of one human life serves as a disaster - storms, tornadoes, hurricanes, for nature, on a scale of hundreds and thousands of years, are a completely ordinary phenomenon. On the one hand, an increase in the level of cosmic radiation by several tens of percent due to the disappearance of the field (and this is precisely the assessment given by V.P. Shcherbakov) may not bring any catastrophic consequences to humanity. On the other hand, it is unlikely that another dying cancer patient will be consoled by the fact that his individual personal tragedy on a global scale will not create a global catastrophe.
Thus, there are quite compelling reasons to pay close attention to the expected soon (and already gaining momentum) inversion and try to figure out what dangers it may pose to humanity and each of its individual representatives - and in the future, to develop a protection system that reduces them Negative consequences. As for protection systems, however, it is too early to talk, if only because we do not even know for sure the origin of the geomagnetic field. But it is quite possible to organize closer monitoring of its changes. According to Academician V.N. Strakhov, for this it is necessary to build a network of observation stations. The costs are quite high: several billion rubles, but we will be able to accurately monitor this process and select a model, as well as the time of a radical change in the geomagnetic field.
The weakening of the Earth's magnetic shield will expose us to solar magnetic radiation. Analysis of data from two satellites, Oersted, launched in 1999, and Magsat, launched 20 years earlier, confirm that the Earth's magnetic field experiences significant fluctuations. It is now impossible to say whether this is a temporary effect associated with the fact of moving away from the ecliptic, or a harbinger of a longer-term phenomenon, but in both cases this is alarming data.
Decrease in the density of the Earth's magnetic field
The strength of the Earth's magnetic field appears to have decreased by 10% over the past 150 years, leading some to speculate that it may disappear over time and then resume and shift, leading to a shift in the magnetic poles for the first time in 700,000 years.
Instability of the north magnetic pole
The earth behaves like a huge dynamo. Iron and nickel, in a liquid state, make up the Earth's core, move around and create a vast magnetic field that envelops the Earth. But since the matter that makes up the core is in constant motion, the magnetic poles are also constantly moving.
Thus, the north magnetic pole does not coincide with the geographic north pole, now it is at the level of Canada and tends to get closer to the geographic pole, moving towards Russia (Siberia) along the northwest axis.
This movement is accelerating from a speed of 10 km per year before 1970 to today's rate of 40 km per year. However, according to Larry Nevitt of the Geological Commission of Canada, the observed acceleration of the north magnetic pole is a consequence of what scientists call "secular jumps" that nullify any predictions.
The problem is that this continued acceleration of the north pole is associated with a decrease in the strength of the magnetic field and may equally lead to the idea that the electromagnetic configuration of the Earth is no longer stable and is tending to reshape itself.
Indeed, from a geological point of view, the south magnetic pole is not content to move towards the north geographic pole. Periodically, it fluctuates suddenly and roughly, and this can occur within 180 ◦. Research into polarity changes spans 7 million years. They indicate that significant changes occur every 500 thousand years.
Luke Fleury. The Epoch Times
The earth is surrounded by a magnetic field. It is what causes the compass needle to point north and protects our atmosphere from the constant bombardment of charged particles from space, such as protons. Without a magnetic field, our atmosphere would slowly disappear under the influence of harmful radiation, and life would almost certainly not be able to exist in the form we see today.
Geomagnetic inversions
You may think that the magnetic field is an infinite, constant aspect of life on Earth, and to some extent you would be right. But the Earth's magnetic field is actually changing. About once every few hundred thousand years or so it turns over. The North Pole changes places with the South Pole. And when this happens, the magnetic field also tends to become very weak.
South Atlantic Anomaly
Currently, geophysicists are alarmed by the realization that the strength of the Earth's magnetic field has been declining at an alarming rate over the past 160 years. This collapse is concentrated in a vast area of the southern hemisphere and stretches from Zimbabwe to Chile. It is known as the South Atlantic Anomaly. The strength of the magnetic field in this place is so weak that it even poses a danger to satellites that orbit the Earth over this area. The magnetic field no longer protects them from radiation that interferes with satellite electronics. 
Consequences of a magnetic field reversal
But that is not all. The strength of the magnetic field continues to weaken, potentially heralding even more dramatic events, including a global reversal of the magnetic poles. This significant change will affect our navigation systems as well as the transmission of electricity. The Northern Lights will be visible at different latitudes. In addition, at very low field strengths during a global roll, more radiation will reach the Earth's surface, which could also affect cancer rates.
Scientists still do not fully understand the extent to which these effects will be achieved, so their research is especially relevant. They use some perhaps surprising sources of data, including 700 years of African archaeological records, to explore this question. 
Origin of the Earth's magnetic field
The Earth's magnetic field is created by the presence of iron in the liquid outer core of our planet. Thanks to data from observatories and satellites that study the magnetic field in Lately, scientists can accurately simulate what it would look like if we placed a compass directly above the Earth's swirling liquid core.
Reverse polarity spot
These analyzes reveal a striking feature: below southern Africa, there is a patch of reverse polarity at the core-mantle boundary, where the liquid iron of the outer core meets the rigid part of the Earth's interior. In this region, the polarity of the field is opposite to the average global magnetic field. If we could install a compass deep under southern part Africa, you would see that in this unusual region the arrows indicating north actually point south. 
This spot is the main culprit of the anomaly in the South Atlantic. In numerical simulations, unusual spots similar to this one appeared just before geomagnetic reversals.
Throughout the history of the planet, the magnetic poles have changed quite often, but the last reversal occurred in the distant past, approximately 780 thousand years ago. Given the rapid decline in magnetic field strength over the past 160 years, questions arise about what happened before then.
Study of archaeomagnetism
During archaeomagnetic research, geophysicists and archaeologists try to learn about the past of the magnetic field. For example, clay that was used to make pottery contains small amounts of magnetic minerals such as magnetite. When clay was heated during the process of creating pottery, its magnetic minerals lost any magnetism they may have had. As they cooled, they recorded the direction and intensity of the magnetic field at that time. If the age of pottery can be determined (using radiocarbon dating, for example), then there is also a chance to reconstruct archaeomagnetic history. 
Using this kind of data, scientists have a partial history of archaeomagnetism for the Northern Hemisphere. In contrast, in the Southern Hemisphere these records are very sparse. In particular, there is virtually no data from South Africa, although this region, along with South America, could provide a better understanding of the history of the modern anomaly.
Archaeomagnetic history of southern Africa
But the ancestors of modern South Africans, the metallurgists and farmers who began migrating to the region some 2,000 to 1,500 years ago, inadvertently left us some clues. These Iron Age people lived in huts made of mud and stored grain in fortified clay silos. As early Iron Age agronomists in southern Africa, they relied on rainfall. 
These communities often responded to times of drought with cleansing rituals that entailed the burning of granaries. These somewhat tragic events for ancient people ultimately turned out to be a boon for the study of archaeomagnetism. As with the firing and cooling of pottery, the clay in the granaries recorded the Earth's magnetic field as it cooled. Because these ancient huts and grain silos are sometimes found intact, scientists can use them to obtain data about the direction and strength of the magnetic field at that time.
The scientists focused their attention on sampling from the Iron Age sites that dot the Limpopo River valley. 
Magnetic field flux
Sampling along the length of the Limpopo River provided the first data on the magnetic field of southern Africa between 1000 and 1600 AD. Scientists found that around 1300 the strength of the magnetic field in this area was declining as quickly as it is today. Then its intensity increased, although at a slower pace.
The appearance of two intervals of rapid field decay - about 700 years ago and modern - suggests the opposite phenomenon. Perhaps a similar anomaly appeared regularly in South Africa and is older than the data showed? If so, why is it repeated in the same place?
Over the past decade, researchers have accumulated data from analyzes of seismic waves from earthquakes. As seismic waves travel through the layers of the Earth, the speed at which they travel is an indicator of the density of the layer. Scientists now know that a large area of slow seismic waves characterizes the main mantle boundary beneath southern Africa. 
This particular region is likely tens of millions of years old, and its boundaries are clear. It is interesting to note that the spot of reverse polarity practically coincides with its eastern edge.
Scientists believe that the unusual African mantle changes the flow of iron into the core from below, which in turn changes the behavior of the magnetic field at the edge of the seismic region and the reverse polarity patch.
This area is expected to grow rapidly and then slowly return to normal. From time to time, one spot of reverse polarity can become large enough to dominate the magnetic field of the southern hemisphere. 
How does inversion happen?
The traditional idea of an inversion is that it can start anywhere in the nucleus. However, a new conceptual model suggests that there may be special locations at the core-mantle boundary that promote these magnetic field reversals. It is not yet known whether the current magnetic field will begin to weaken in the next few thousand years, or whether it will simply continue to weaken over the next two centuries.
But the evidence provided by the ancestors of modern South Africans will undoubtedly help scientists further study their proposed inversion mechanism. If this idea is correct, a pole reversal could begin in Africa.
27.07.11
The Earth's magnetic layer began to shrink at high speed.
This will lead to an increase in background radiation and a weakening of the protection of all living things. World science is concerned: new satellites are being launched to record the pace of these messages.
General: The Earth has a magnetic field, North Pole which is located at the geographic south pole.
To obtain a magnetic field in the desired direction, there must be a stable current layer around the globe, in a plane perpendicular to the Earth's rotation axis. Such a layer exists and is called the ionosphere.
The sun, as a result nuclear reactions flowing in it, emits a huge amount of charged particles of high energy into the surrounding space, the so-called solar wind.
The composition of the solar wind contains mainly protons, electrons, some helium nuclei, oxygen, silicon, sulfur, and iron ions. The particles that form the solar wind are carried away by the upper layers of the atmosphere in the direction of the Earth's rotation. Thus, a directed flow of electrons is formed around the Earth, moving in the direction of the Earth’s rotation. As a result of the presence of this current, the Earth's magnetic field is excited.
As a result of the interaction of the ionospheric current and the Earth's magnetic field, a torque directed in the direction of the Earth's rotation acts on the Earth.
Thus, the Earth is relatively solar wind behaves similarly to a self-excited DC motor. The energy source (generator) in this case is the Sun.
It should be noted that the magnetic flux caused by the solar wind current penetrates the flow of hot lava rotating with the Earth inside it.
As a result of the interaction of the ionospheric current field and the flow of hot lava, electromotive force, under the influence of which a current flows, which also creates a magnetic field. As a result, the Earth's magnetic field is the resulting field from the interaction of the ionospheric current and the lava current.
Since both the magnetic field and the torque acting on the earth depend on the current in the ionosphere, and the latter on the degree solar activity, then with increasing solar activity the torque acting on the Earth should increase and the speed of its rotation should increase.
What is happening to the Earth's magnetic field today? – I asked the famous nuclear physicist Igor Nikolaevich Ostretsov.
The actual picture of the Earth's magnetic field depends not only on the configuration of the current sheet, but also on the magnetic properties of the earth's crust, as well as on the relative location of magnetic anomalies.
Here we can draw an analogy with a circuit with current in the presence of a ferromagnetic core and without it. It is known that the ferromagnetic core not only changes the configuration of the magnetic field, but also significantly enhances it.
The Earth's current layer largely determines the occurrence of electrical processes in the atmosphere (thunderstorms, auroras, St. Elmo's lights).
It has been noticed that during volcanic eruptions, electrical processes in the atmosphere are significantly activated. This phenomenon can be explained as follows. When a volcano erupts, a column of hot gases (plasma) is released. The convective movement of hot gases closes the current layer of the ionosphere with the Earth's surface. Thus, a leakage current appears, which activates electrical processes during eruptions.
In particular, it is possible that the interrelation of electromagnetic processes in the Sun-Earth system may provide the possibility of developing powerful power plants using solar energy.
It is known that the geographic poles constantly make complex loop-like movements in the direction of the daily rotation of the Earth with a period of 25,776 years.
Typically, these movements occur near the imaginary axis of rotation of the Earth and do not lead to noticeable climate change. But few people noticed that at the end of 1998 the overall component of these movements shifted. Within a month, the pole shifted towards Canada by 50 kilometers. Currently, the North Pole is “creeping” along the 120th parallel of western longitude.
It can be assumed that if the current trend in pole movement continues until 2015, the north pole could shift by 3-4 thousand kilometers. The end point of the drift is the Great Bear Lakes in Canada. The South Pole will accordingly shift from the center of Antarctica to the Indian Ocean.
The displacement of magnetic poles has been recorded since 1885. Over the past 100 years, the magnetic pole in the southern hemisphere has moved almost 900 km and reached Indian Ocean.
The latest data on the state of the Arctic magnetic pole (moving towards the East Siberian world magnetic anomaly through the Arctic Ocean): showed that from 1973 to 1984. its movement was 120 km, from 1984 to 1994. - more than 150 km. It is characteristic that these calculated data were confirmed by specific measurements of the location of the north magnetic pole. According to data at the beginning of 2002, the drift speed of the north magnetic pole increased from 10 km/year in the 70s to 40 km/year in 2001.
In addition, the strength of the earth's magnetic field drops, and very unevenly.
Thus, over the past 22 years it has decreased by an average of 1.7 percent, and in some regions - for example, in the South Atlantic Ocean - by 10 percent. However, in some places on our planet the magnetic field strength, contrary to the general trend, has even increased slightly.
We emphasize that the acceleration of the movement of the poles (on average by 3 km/year per decade) makes us think that this movement of the poles should be seen not as a special phenomenon, but as a reversal of the Earth’s magnetic field.
The acceleration could bring the poles to move up to 200 km per year, so that the reversal will take place much faster than is currently expected. And of course it's not safe.
In the history of the Earth, changes in position geographic poles occurred repeatedly, and this phenomenon is primarily associated with the glaciation of vast areas of land and dramatic changes in the climate of the entire planet.
Writers called another name for this phenomenon “earth somersault.”
But only the last catastrophe, most likely associated with a pole shift, which occurred about 12 thousand years ago, received echoes in human history. All we know is that mammoths are extinct. But everything was much more serious.
The extinction of hundreds of animal species is beyond doubt.
There are discussions about the Great Flood, the Death of Atlantis, and the emergence of the Black Sea. But one thing is certain - the echoes of the greatest catastrophe in human memory have a real basis. And it is most likely caused by a pole shift of only 2000 km.
Dear Igor Nikolaevich, please comment on what caused the repolarization and is it dangerous for humanity?
Scientists have long wondered why the Earth's magnetic poles switch places from time to time. Recent studies of vortex movements of molten masses inside the Earth make it possible to understand how repolarization occurs. The magnetic field is much more intense and more difficult fields the core, within which magnetic oscillations are formed, was discovered at the boundary of the mantle and core.
It is important that most of the geomagnetic field is generated only in four broad regions at the core-mantle boundary. Although the geodynamo produces a very strong magnetic field, only 1% of its energy travels outside the core. The general configuration of the magnetic field measured at the surface is called a dipole, which most of the time is oriented along the earth's axis of rotation. As in the field of a linear magnet, the main geomagnetic flow is directed from the center of the Earth in the Southern Hemisphere and towards the center in the Northern Hemisphere. Space observations showed that the magnetic flux has an uneven global distribution, the highest intensity can be traced on the Antarctic coast, under North America and Siberia.
Ulrich R. Christensen from the Research Institute solar system Max Planck in Katlenburg-Lindau, Germany, believes that these vast areas of land have existed for thousands of years and are maintained by ever-evolving convection within the core.
Could similar phenomena be the cause of pole reversals? Historical geology shows that pole changes occurred in relatively short periods of time - from 4 thousand to 10 thousand years. If the geodynamo had stopped working, the dipole would have existed for another 100 thousand years. A rapid change in polarity gives reason to believe that some unstable position violates the original polarity and causes a new change of poles.
In some cases, the mysterious instability can be explained by some chaotic change in the structure of the magnetic flux, which only accidentally leads to repolarization.
However, the frequency of polarity changes, which has become more and more stable over the past 120 million years, indicates the possibility of external regulation. One of the reasons for this may be a temperature difference in the lower layer of the mantle, and as a result, a change in the nature of core outpourings.
Some symptoms of repolarization were identified when analyzing maps that were made from satellites.
Long-term changes in the geomagnetic field occur at the boundary of the core and mantle in those places where the direction of the geomagnetic flow is opposite to the normal one for a given hemisphere. The largest of the so-called reverse magnetic field stretches from the southern tip of Africa west to South America. In this area, the magnetic flux is directed inward, towards the core, while most of it in the Southern Hemisphere is directed from the center.
Regions where the magnetic field is directed in the opposite direction for a given hemisphere arise when twisted and winding magnetic field lines accidentally break through beyond the Earth's core.
Areas of reversed magnetic field can significantly weaken the magnetic field on the Earth's surface, called a dipole, and indicate the beginning of a reversal of the Earth's poles. They appear when rising liquid mass pushes horizontal magnetic lines upward in the molten outer core. In this sense, it is difficult to predict exactly how the climate on the Planet will change. And such changes, of course, can lead to disasters.
The most significant discovery made by comparing the latest measurements was that new areas of inverted magnetic field continue to form, for example at the core-mantle boundary under the east coast of North America and the Arctic.
Moreover, previously identified areas have grown and moved slightly towards the poles. At the end of the 80s. XX century David Gubbins of the University of Leeds in England, studying old maps of the geomagnetic field, noted that the spread, growth and poleward shift of sections of the inverse magnetic field explains the decline in dipole strength over historical time.
When rotation brings a section of the reversed magnetic field closer to the geographic pole than the section with normal flux, there is a weakening of the dipole, which is most vulnerable near its poles.
This can explain the reversed magnetic field in southern Africa. With the global onset of a pole reversal, areas of reversed magnetic fields can grow throughout the region near the geographic poles.
But Kiev professor, Doctor of Physical and Mathematical Sciences, Director of the Ukrainian Institute of Human Ecology Mikhail Vasilyevich Kurik connects life expectancy with the strength of the Earth’s magnetic field.
Fifty years ago, the famous Japanese scientist, Dr. Nakagawa, described a new disease that affects a huge number of people on earth, and called it “human magnetic field deficiency syndrome.”
Dr. Nakagawa came to a very serious conclusion that made it possible to treat large quantity diseases. He described the “magnetic field deficiency syndrome,” leading to the formation of dozens of pathological processes. The main manifestations of the syndrome are: general weakness, increased fatigue, decreased performance, poor sleep, headache, pain in the joints and spine, pathology of cardio-vascular system, hyper- and hypotension, digestive disorders, skin changes, prostate problems, gynecological dysfunctions and a number of other processes.
Tell me: do problems with weak magnetic fields really exist?
Since the Earth's magnetic field simultaneously protects humans from dangerous solar and cosmic radiation, according to scientists, a decrease in the magnetic field at high altitudes increases the risk of such dangerous effects for the body.
In the experiments, mice were placed in chambers shielded from the Earth's magnetic field. Within a day, their tissues began to decompose. The cubs of such mice were born bald and grew up sick.
The planet's magnetic field protects us from high-energy plasma streams emitted by the Sun.
A decrease in the Earth's magnetic field means a weakening of this protection and a corresponding increase in background radiation. Which, of course, can lead to serious illnesses.
Any person who observes the phenomena occurring these days related to global climate change on the planet, one way or another, but thinks, firstly, about the reasons for the increase in number and strength natural disasters, secondly, on the possibility of long-term forecasting of natural disasters in order to help society. After all, today there is more and more information about humanity’s entry into the era of global natural disasters. Is it possible, if not completely preventing, then at least minimizing the consequences of global climate change on the planet? The search led to very impressive and positively encouraging information - a report by the ALLATRA SCIENCE community of scientists: "On the problems and consequences of global climate change on Earth. Effective ways to solve these problems." The report contains unique information for each person, as this is the key to solving climate problems of any complexity. It also shows a real way out of the current situation through the unification of the world community on a creative, spiritual and moral basis.
The Earth’s magnetic field is the planet’s natural “shield” from cosmic and solar radiation harmful to all living things. In fact, if the Earth did not have its own magnetic field, then life, in the form we are familiar with, would be impossible on it. The strength of the Earth's magnetic field is distributed non-uniformly and averages about 50,000 nT (0.5 Oe) on the surface and varies from 20,000 nT to 60,000 nT.

However, observations show that the Earth's magnetic field is gradually weakening, while the geomagnetic poles are shifting. As stated in the above-mentioned report, these processes are influenced, first of all, by certain cosmic factors, although traditional science does not yet know about them and does not take them into account, trying to find answers in the bowels of the Earth to no avail.
Data transmitted by the Swarm satellites launched by the European Space Agency (ESA) confirm the general trend of weakening magnetic field strength, with the greatest level of decline observed in the Western Hemisphere of our planet.

Analyzing the consequences of many natural disasters, scientists have found that before the onset of seismic activity, anomalies in the Earth's magnetic field appear. In particular, the earthquake that occurred on March 11, 2011 in Japan was preceded by the activation of the Pacific lithospheric plate in subduction zones. This event became a kind of indicator of a new phase of seismic activity associated with the acceleration of the movement of this lithospheric plate. Displacement of geomagnetic poles located in Eastern Siberia and the Pacific Ocean, due to cosmic factors, led to large-scale changes in secular magnetic variations in the territory of the Japanese archipelago. The result of these phenomena was a series powerful earthquakes, magnitude 9.0.
It is officially believed that over the past 100 years, the Earth's magnetic field has weakened by about 5%. In the area of the so-called South Atlantic Anomaly off the coast of Brazil, the weakening was even more significant. However, it is worth noting that earlier, as now, ground-based measurements were carried out pointwise, and on land, which can no longer reflect the full picture of secular changes in the magnetic field. Also, holes in the Earth’s magnetic field are not taken into account - peculiar gaps in the magnetosphere through which huge flows of solar radiation penetrate. For reasons unknown to traditional science, the number of these holes is constantly growing. But we will talk about them in the following publications.
It is known that the weakening of the Earth’s magnetic field leads to a polarity reversal, in which the north and south magnetic poles change places and their inversion occurs. Research in the field of paleomagnetism has shown that earlier, during polar reversals, which occurred gradually, the Earth's magnetic field lost its dipole structure. The inversion of the magnetic field was preceded by its weakening, and after it the field strength again increased to its previous values. In the past, these reversals occurred on average approximately every 250,000 years. But since the last one, according to scientists, about 780,000 years have passed. However, official science cannot yet provide any explanation for such a long period of stability. In addition, the correctness of interpretation of paleomagnetic data is periodically criticized in scientific circles. One way or another, the rapid weakening of the magnetic field these days is a sign of the beginning of global processes both in outer space and in the bowels of the Earth. That is why the cataclysms occurring on the planet are caused to a greater extent by natural factors than by anthropogenic influence.
Traditional science is still finding it difficult to find an answer to the question: what happens to the magnetic field at the moment of inversion? Does it disappear completely or weaken to certain critical values? There are many theories and assumptions on this subject, but none of them seems reliable. One of the attempts to simulate the magnetic field at the time of reversal is shown in Fig. 3:
Rice. 3. Model representation of the main magnetic field of the Earth in its current state(left) and in the process of polarity reversal (right). Over time, the Earth's magnetic field can turn from dipole to multipole, and then a stable dipole structure will form again. However, the direction of the field will change to the opposite: the north geomagnetic pole will be in the place of the south, and the south will move to the Northern Hemisphere.
The very fact of the presence of significant magnetic anomalies at the time of polarity reversal can lead to global tectonic phenomena on Earth, and also pose a serious danger to all life on the planet due to the increasing level of solar radiation.
PRIMORDIAL ALLATRA PHYSICS is developing methods for observing the Earth’s magnetic field, as well as the Earth’s septon field. These data make it possible to respond in a timely manner to their variations and take countermeasures aimed at eliminating or minimizing natural disasters. Early identification of sources of future disasters (earthquakes, volcanic eruptions, tornadoes, hurricanes) makes it possible to launch adaptive mechanisms, due to which the intensity of seismic and volcanic activity is significantly reduced, and there is time to warn the population living in a dangerous area. This direction of advanced scientific research is called climate geoengineering and includes the development of a new direction and methods that are completely safe for the integrity of the ecosystem and human life, based on a fundamentally new understanding of physics - the PRIMORDIAL ALLATRA PHYSICS. To date, a number of successful steps have been taken in this direction, which have acquired solid scientific basis and practical confirmation. The initial stage of practical development of this area is already demonstrating stable results... .
In a period of ever-increasing danger of global climate events, it is vital for humanity to unite on creative spiritual and moral foundations, constantly expand the knowledge of PRIMORDIAL ALLATRA PHYSICS, and develop promising scientific directions mentioned in the report. SPIRITUALITY and ALLATRA SCIENCE are precisely the solid foundation that will allow humanity to survive in the era of global climate change and create, in new conditions, a new type of society that humanity has long dreamed of. Initial knowledge was given in the reports of the ALLATRA SCIENCE community, and now a lot depends on each person so that it is used exclusively for good!
