View Photo (https://uk.news.yahoo.com/lightbox/measurements-made-over-past-six-months-confirm-general-photo-154432958.html) Press Association - Measurements made over the past six months confirm the general trend of the field's weakening, with the most dramatic declines over the western hemisphere
These high-resolution images show the most recent changes in the magnetic field that protects our planet.
They have been released by the European Space Agency (ESA) from its three-satellite Swarm Mission (http://projectavalon.net/forum4/SWARM) which was launched last year.
Measurements made over the past six months confirm the general trend of the field's weakening, with the most dramatic declines over the western hemisphere.
In other areas, such as the southern Indian Ocean, the magnetic field has strengthened since January.
The latest measurements also confirm the movement of magnetic North towards Siberia.
These changes are based on the magnetic signals stemming from Earth's core.
Over the coming months, scientists will analyse the data to unravel the magnetic contributions from other sources, namely the mantle, crust, oceans, ionosphere and magnetosphere.
Scientists behind the Swarm Mission (http://projectavalon.net/forum4/SWARM) say the research will provide new insight into many natural processes, from those occurring deep inside our planet to space weather triggered by solar activity.
In turn, this information will yield a better understanding of why the magnetic field is weakening.
"These initial results demonstrate the excellent performance of Swarm," said Rune Floberghagen, ESA's Swarm Mission manager.
"With unprecedented resolution, the data also exhibit Swarm's capability to map fine-scale features of the magnetic field."
The first results were presented at the Third Swarm Science Meeting in Copenhagen, Denmark.

So, two North Poles? Not quite! Meaning that the Earth's "magnet" and it corresponding magnetic field is becoming asymmetric.
Check the South Atlantic Anomaly (https://en.wikipedia.org/wiki/South_Atlantic_Anomaly) (SAA) to get a better idea of what's being monitored.

Description: This animation shows changes in Earth’s magnetic field from January to June 2014 as measured by ESA’s Swarm trio of satellites.
The magnetic field protects us from cosmic radiation and charged particles that bombard Earth, but it is in a permanent state of flux. Magnetic north wanders, and every few hundred thousand years the polarity flips so that a compass would point south instead of north. Moreover, the strength of the magnetic field constantly changes – and it is currently showing signs of significant weakening.
The field is particularly weak over the South Atlantic Ocean – known as the South Atlantic Anomaly. This weak field has indirectly caused many temporary satellite ‘hiccups’ (called Single Event Upsets) as the satellites are exposed to strong radiation over this area.

Pretty dramatic I would say. I had no idea that the field was bifurcating in this manner. It does look to me like pole reversal is now occurring. I have been interested for some time in the visions of Stalking Wolf from the 1920s which include a vision of "holes in the sky". I have wondered if these holes might possibly have something to do with the topology of the earth's magnetic field during a pole reversal, that is, whether there would be a breaking apart of the dipole field into a more complex field with a number of weak field regions or holes (as for example the South Atlantic anomaly). Stalking Wolf's visions were reported by Tom Brown, Jr. the wilderness tracker and they are apocalyptic. I myself had a dream that I have interpreted as meaning possibly a pole reversal. I dream that I am an American Indian. (For some reason I am in England). I have done something that scientists have not been able to do. I have drilled a hole to the center of the earth. At the center of the earth I see a block of ice maybe a few cubic feet in size and I start to break the ice up with my tomahawk. I had this dream BEFORE i knew anything of the changing magnetic field or of Stalking Wolf's vision.
Well, it is said that one should not interpret one's own dreams. And my sheik interpreted this dream in totally personal terms. Yet, somehow I feel that this dream was not just personal but prophetic. I had it more than eight years ago.
THE FOUR PROPHECIES OF STALKING WOLF
Preface
Jan Robertson
janar@dove.net.au
Stalking wolf was given four prophesies, they were told to him in about 1920. The first two have already come true, and cannot be misunderstood as they are very specific. He said that after the third prophecy took place there was no possibility to save our planet, but up until then it was possible to change the course of nature by prayer and a joining of minds (not specifically in those words) after the third prophecy took place he said there would be 4 seasons of peace to prepare for the incredible and terrible 4th and only the "Children of the Earth would suvive". I thought as I read this site what a tremendous opportunity to help our earth and monitor the results. We need to find clean, renewable and sustainable energy, and increase our knowledge and usage of natural medicines, so we can rid the earth of all pollutants, enabling us to heal our sick planet.
Grandfather
Tom Brown Jr.
"Out of all of the personal and major prophecies that Grandfather foretold, there are four that stand out above all the rest. It is these four that mark the destruction of man, and life on Earth as we know it. Yet Grandfather said we could still change things, even after the first two prophecies come true, but that there could be no turning back after the third." This vision was given to the old Apache in the 1920s, and Tom met him when he was in his eighties. That was in 1962.
"How will I know that we are so close to destruction?" I asked.
Grandfather said, "I had a vision, It was a vision of the destruction of man. But man was given four warnings , two of which gave man a chance to change his ways and two of which would give the children of the Earth time to escape the Creator's wrath."
"How will I know these signs?" I asked, and Grandfather continued, "They will be obvious to you and those who listen to the Spirit of the Earth, but to those who live within the flesh and know only flesh, there is no knowing and no understanding. When these signs, these warnings and prophecies, are made manifest, then you will understand the urgency of what I speak. Then you will understand why people must not just work for their own spiritual rapture, but to bring that rapture to the consciousness of modern people"
Grandfather had just finished his third Vision Quest at the Eternal Cave when the spirit of the warrior appeared to him. The spirit called Grandfather's name and beckoned him to follow. As Grandfather stood, he was suddenly transported to another world and he thought that he was dreaming, but his flesh could feel the reality of this place; his senses knew that this was a state of abject reality but in another time and place.
"The spirit warrior spoke to Grandfather, saying, 'These are the things yet to come that will mark the destruction of man. These things you may never see, but you must work to stop them and pass these warnings on to your grandchildren. They are the possible futures of what will come if man does not come back to the Earth and begin to obey the laws of Creation and the Creator. There are four signs, four warnings, that only the children of the Earth will understand. Each warning marks the beginning of a possible future.' With that the spirit warrior was gone, and Grandfather was left alone in this strange new world.
"The world he was in was like nothing he had ever known. It was a dry place, with little vegetation. In the distance he saw a village, yet it was made out of tents and cloth rather than from materials of the Earth As he drew closer to the village the stench of death overwhelmed him and he grew sick. He could hear children crying, the moaning of elders, and the sounds of sickness and despair. Piles of bodies lay in open pits awaiting burial, their contorted faces and frail bodies foretelling of death from starvation. The bodies appeared more like skeletons than flesh, their once dark brown complexions now ash grey.
"As Grandfather entered the village, the horror of living starvation struck him deeper. Children could barely walk, elders lay dying, and everywhere were the cries of pain and fear. The stench of death and the sense of hopelessness overwhelmed Grandfather, threatening to drive him from the village. It was then that an elder appeared to Grandfather, at first speaking in a language that he could not understand. Grandfather realized as the elder spoke that he was a spirit of a man, a man no longer of the flesh but a man that had walked a spiritual path, possibly a shaman of his tribe. It was then that he understood what the old one was trying to tell him.
"The elder spoke softly saying, 'Welcome to what will be called the land of starvation. The world will one day look upon all of this with horror and will blame the famine on the weather and the Earth. This will be the first warning to the world that man cannot live beyond the laws of Creation, nor can he fight Nature. If the world sees that it is to blame for this famine, then a great lesson will be learned. But I am afraid that the world will not blame itself, but that the blame will be placed on Nature. The world will not see that it created this place of death.
"The old one continued. 'These people should have been left alone. They once understood how to live with Earth, and their wealth was measured in happiness, love, and peace. But all of that was taken away from them when the world saw theirs as a primitive society. It was then that the world showed them how to farm and live in a less primitive way. It was the world that forced them to live outside the laws of creation and as a result it is now forcing them to die.' The old man slowly began to walk away, back to death and despair.
"He turned one last time to Grandfather and said, 'This will be the first sign. There will come starvation before and after this starvation, but none will capture the attention of the world with such impact as does this one The Children of the Earth will know the lessons that are held in all this pain and death, but the world will only see it as drought and famine, blaming Nature instead of itself.' With that the old one disappeared, and Grandfather found himself back at the mouth of the Eternal Cave.
Grandfather knew that people all over the Earth were now starving, but why was this starvation so critical, so much more important than the starvation that was taking place now? It was then that Grandfather recalled that the tribal elder had said that the entire world would take notice but that the world would not learn the lessons of what the death and the famine were trying to teach. The Children of the Earth would die in vain.
In a state of physical and emotional exhaustion, Grandfather fell into a deep sleep, but it was in this sleep that the warrior spirit appeared to him again and brought the remainder of the first sign to completion. In this dream the spirit spoke to Grandfather saying, 'It is during the years of the famine that all will be plagued by a disease, a disease that will sweep the land and terrorize the masses. The white coats (doctors) will have no answers for the people, and a great cry will arise across the land. The disease will be borne of monkeys, drugs, and sex. It will destroy man from inside, making common sickness a killing disease. Mankind will bring this disease upon himself as a result of his life, his worship of sex and drugs, and a life away from Nature.
The spirit continued, saying, 'The drugs will produce wars in the cities of man, and the nations will arise against those wars, arise against that killing disease. But the nations will fight in the wrong way, lashing out at the effect rather than the cause. It will never win these wars until the nation, until society changes its values and stops chasing the gods of sex and drugs.'
It is then in the years of the first sign, that man can change the course of the probable future. It is then that he may understand the greater lessons of the famine and the disease. It is then that there can still be hope. But once the second sign of destruction appears, the Earth can only be healed on a spiritual level. Only a spiritual healing can then change the course of the probable futures of mankind. With that the warrior spirit let Grandfather fall into a deep and dreamless sleep, allowing him to rest fully before any more Vision was wrought upon him.
Second vision
Grandfather awoke at the entrance of the cave once again, the memory of the warrior spirit vivid in his mind, the spirit's words becoming part of his soul. When Grandfather looked out across the landscape, all had changed. The landscape appeared dryer, there was no vegetation to be seen, and animals lay dying. A great stench of death arose from the land, and the dust was thick and choking, the intense heat oppressive. Looking skyward, the sun seemed to be larger and more intense; no birds or clouds can be seen; and the air seemed thicker still. It was then that the sky seemed to surge and huge holes began to appear. The holes tore with a thunderous sound, and the very Earth, rocks, and soil shook. The skin of the sky seemed to be torn open like a series of gaping wounds, and through these wounds seeped a liquid that seemed like the oozing of an infection, a great sea of floating garbage, oil, and dead fish. It was through one of these wounds that Grandfather saw the floating bodies of dolphins, accompanied by tremendous upheavals of the Earth and of violent storms.
As he held fast to the trembling Earth his eyes fell from the sky, and all about him, all at once, was disaster. Piles of garbage reached to the skies, forests lay cut and dying, coastlines flooded, and storms grew more violent and thunderous. With each passing moment the Earth shook with greater intensity, threatening to tear apart and swallow Grandfather.
Suddenly the Earth stopped shaking and the sky cleared. Out of the dusty air walked the warrior spirit, who stopped a short distance from Grandfather. As Grandfather looked into the face of the spirit he could see that there were great tears flowing from his eyes, and each tear fell to the Earth with a searing sound. The spirit looked at Grandfather for a long moment, then finally spoke, saying, "Holes in the sky". Grandfather thought for a moment, then in a questioning, disbelieving manner said, 'Holes in the Sky?' And the spirit answered, saying, "They will become the sign of the destruction of man. The holes in the sky ,and all that you have seen could become man's reality. It is here, at the beginning of this second sign, that man can no longer heal the Earth with physical action. It is here that man must heed the warning and work harder to change the future at hand. But man must not only work physically, he must also work spiritually, through prayer, for only through prayer can man hope to heal the Earth and himself."
There was a long pause as Grandfather thought of the impossibility of holes in the sky. Surely Grandfather knew that there could be a spiritual hole, but a hole that the societies of Earth could notice would hardly seem likely. The spirit drew closer and spoke again, almost in a whisper. "These holes are a direct result of man's life, his travel, and the sins of his grandfathers and grandmothers. These holes, the second sign, will mark the killing of his grandchildren and will become a legacy to man's life away from Nature. It is the time of these holes that will mark a great transition in mankind's thinking. They will then be faced with a choice, a choice to continue the path of destruction or a choice to move back to the philosophy of the Earth and a simpler existence. It is here that the decision must be made, or all will be lost." Without another word the spirit turned and walked back into the dust.
Grandfather spent the next four days at the cave entrance, though for the next four days nothing spoke to him, not even the Earth. He said that it was a time of great sorrow, of aloneness, and a time to digest all that had taken place. He knew that these things would not appear in his life time, but they had to be passed down to the people of the future, with the same urgency and power with which they had been delivered to him. But he did not know how he could explain these unlikely events to anyone. Surely the elders and shamans of the tribes would understand but not society, and certainly not anyone who was removed from the Earth and spirit. He sat for the four full days, unmoving, as if made of stone.
It was at the end of the fourth day that the third Vision came to him. As he gazed out onto the landscape toward the setting sun, the sky suddenly turned back to a liquid and turned blood red. As far as his eyes could see, the sky was solid red, with no variation in shadow, texture, or light. The whole of creation seemed to have grown still, as if awaiting some unseen command. Time, place, and destiny seemed to be in limbo, stilled by the bleeding sky. He gazed for a long time at the sky, in a state of awe and terror, for the red color of the sky was like nothing he had ever seen in any sunset or sunrise. The color was that of man, not of Nature, and it had a vile stench and texture. It seemed to burn the Earth wherever it touched. As sunset drifted to night, the stars shone bright red, the color never leaving the sky, and everywhere was heard the cries of fear and pain.
"Again the warrior spirit appeared to Grandfather, but this time as a voice from the sky. Like thunder, the voice shook the landscape, saying, "This, then, is the third sign, the night of the bleeding stars. It will become known throughout the world, for the sky in all lands will be red with the blood of the sky, day and night. It is then, with this sign of the third probable future, that there is no longer hope. Life on Earth as man has lived it will come to an end, and there can be no turning back, physically or spiritually. It is then, if these are not changed during the second sign, that man will surely know the destruction of Earth is at hand. It is then that the children of the Earth must run to the wild places and hide. For when the sky bleeds fire, there will be no safety in the world of man."
Grandfather sat in shocked horror as the voice continued. "From this time, when the stars bleed, to the fourth and final sign will be four seasons of peace. It is in these four seasons they must live deep within the wild places and find a new home, close to the Earth and the Creator. It is only the children of the Earth that will survive, and they must live the philosophy of the Earth, never returning to the thinking of man. And survival will not be enough, for the children of the Earth must also live close to the spirit. So tell them not to hesitate if and when this third sign becomes manifest in the stars, for there are but four seasons (1 yr) to escape." Grandfather said that the voice and the red sky lingered for a week and then were gone as quickly as they were made manifest.
Grandfather did not remember how many days he'd spent at the mouth of the cave, nor did it make a difference, for he had received the Vision he had come for. It was in the final night at the Eternal Cave that the fourth vision came to Grandfather, this time carried by the voice of a young child. The child spoke, saying, "The fourth and final sign will appear through the next ten winters following the night that the stars will bleed. During this time the Earth will heal itself and man will die. For those ten years the children of the Earth must remain hidden in the wild places, make no permanent camps, and wander to avoid contact with the last remaining forces of man. THEY MUST REMAIN HIDDEN, like the ancient scouts and fight the urge to go back to the destruction of man. Curiosity could kill many."
There was a long silence, until Grandfather spoke to the child spirit, asking, "And what will happen to the worlds of man?" There was another period of silence until finally the child spoke again. "There will be a great famine throughout the world, like man cannot imagine. Waters will run vile, the poisons of man's sins running strong in the waters of the soils, lakes, and rivers. Crops will fail, the animals of man will die, and disease will kill the masses. The grandchildren will feed upon the remains of the dead, and all about will be cries of pain and anguish. Roving bands of men will hunt and kill other men for food, and water will always be scarce, getting scarcer with each passing year. The land, the water, the sky will all be poisoned, and man will live in the wrath of the Creator. Man will hide at first in the cities, but there he will die. A few will run to the wilderness, but the wilderness will destroy them, Man will be destroyed, his cities in ruin, and it is then that the grandchildren will pay for the sins of their grandfathers and grandmothers."
"Is there then no hope"? Grandfather asked. The child spoke again, "There is only hope during the time of the first and second signs. Upon the third sign, the night of the bleeding, there is no longer hope, for only the children of the Earth will survive. Man will be given these warnings: if unheeded, there can be no hope, for only the children of the Earth will purge themselves of mankind's destructive thinking. The children of the Earth will bring a new hope to the society, living closer to the Earth and spirit." Then all was silent, the landscape cleared and returned to normal and Grandfather stepped from the vision. Shaken, he said he had wandered for the next season, trying to understand why he had been chosen.

Well, another one biting the dust:
Earth’s Geomagnetic Field Intensity is Double the Historical Average (http://scitechdaily.com/earths-geomagnetic-field-intensity-is-double-the-historical-average/)
November 24, 2015
http://scitechdaily.com/images/Geomagnetic-Field-Intensity-is-Double-the-Long-Term-Historical-Average.jpg

New research from MIT shows that the Earth’s geomagnetic field intensity is double the long-term historical average, indicating that the current field intensity has a long way to fall before reaching an unstable level that would lead to a reversal.
The intensity of Earth’s geomagnetic field has been dropping for the past 200 years, at a rate that some scientists suspect may cause the field to bottom out in 2,000 years, temporarily leaving the planet unprotected against damaging charged particles from the sun. This drop in intensity is associated with periodic geomagnetic field reversals, in which the Earth’s North and South magnetic poles flip polarity, and it could last for several thousand years before returning to a stable, shielding intensity.
With a weakened geomagnetic field, increased solar radiation might damage electronics — from individual pacemakers to entire power grids — and could induce genetic mutations. A reversal may also affect the navigation of animals that use Earth’s magnetic field as an internal compass.
But according to a new MIT study in the Proceedings of the National Academy of Sciences (http://www.pnas.org/content/early/2015/11/18/1505450112.abstract), the geomagnetic field is not in danger of flipping anytime soon: The researchers calculated Earth’s average, stable field intensity over the last 5 million years, and found that today’s intensity is about twice that of the historical average.
This indicates that the current field intensity has a long way to fall before reaching an unstable level that would lead to a reversal.
“It makes a huge difference, knowing if today’s field is a long-term average or is way above the long-term average,” says lead author Huapei Wang, a postdoc in MIT’s Department of Earth, Atmospheric and Planetary Sciences. “Now we know we are way above the unstable zone. Even if the [field intensity] is dropping, we still have a long buffer that we can comfortably rely on.”
Flip-flopping through history
Earth has undergone multiple geomagnetic reversals over its lifetime, flip-flopping its polarity at random intervals.
“Sometimes you won’t have a flip for about 40 million years; other times there will be 10 flips in 1 million years,” Wang says. “On average, the duration between two flips is a few hundred thousand years. The last flip was around 780,000 years ago, so we are actually overdue for a flip.”
The most obvious sign of an impending reversal is a geomagnetic field intensity that’s significantly below its historical, long-term average — a sign that the planet is tipping toward an unstable state. While satellites and ground-based observatories have made accurate measurements over the last 200 years of the current field intensity, there are less reliable estimates over the last few million years.
Wang and his colleagues, from Rutgers University and France, sought to measure Earth’s paleomagnetic field using ancient rocks erupted from volcanoes on the Galapagos Islands — an ideal site, since the island chain is on the equator. As Earth’s magnetic field, in its stable configuration, is a dipole, the intensity of the field should be the same at both poles, and half that intensity at the equator.
Wang reasoned that knowing the paleomagnetic field intensity at the equator and the poles would therefore give an accurate estimate of the planet’s average historical intensity.
Rocks from a dipole
Wang obtained samples of ancient volcanic lavas from the Galapagos, while his colleagues from the Scripps Institution of Oceanography at the University of California at San Diego excavated similarly aged rocks from Antarctica. Such volcanic rocks retain information on the geomagnetic field intensity at the time they cooled.
The two teams brought the samples back to their respective labs, and measured the rocks’ natural remanent magnetization, or orientation of ferromagnetic particles. They then heated the rocks, and cooled them in the presence of a known magnetic field, measuring the rocks’ magnetization after cooling.
A rock’s remanent magnetization is proportional to the magnetic field in which it cooled. Therefore, using the data from their experiments, the researchers were able to calculate the peak distribution of the ancient geomagnetic field intensity, both at the equator — about 15 microtesla — and the poles — about 30 microtesla. Today’s field intensities at the same locations are around 30 microtesla and 60 microtesla, respectively — double the historical, long-term values.
“That means today’s value is anomalously high, and even if it’s dropping, it’s dropping to a long-term average, not from an average to zero,” Wang says.
Far from zero
So why have scientists assumed that Earth’s geomagnetic field is dropping to a precipitous low? It turns out this assumption is based on flawed historical data, Wang says.
Scientists have estimated paleomagnetic intensities at various latitudes around the Earth, but Wang’s is the first data from equatorial regions. However, Wang found that scientists were misinterpreting how rocks recorded their magnetic fields, leading to inaccurate estimates of paleomagnetic intensity. Specifically, scientists were assuming that as individual ferromagnetic grains of rocks cooled, their unpaired electron spins assumed a uniform orientation, reflecting the magnetic field intensity.
However, this effect only holds true up to a certain size. In larger grains, unpaired electron spins assume various orientations in different domains of the grain, thereby complicating the field intensity picture.
Wang developed a method to correct for such multidomain effects, and applied the method to his Galapagos lavas. The results, he says, are more reliable than previous estimates of the paleomagnetic field.
As for when Earth may experience its next flip, Wang says the answer is still up in the air.
“What I can say is, if you keep a constant present-day decrease rate, it will take another 1,000 years for the field to drop to its long-term average,” Wang says.
“From there, the field intensity may go up again. There’s really no way to predict what will happen after that, given the random nature of the magnetohydrodynamic process of the geodynamo.”
As the findings suggest that today’s field intensity is abnormally high, John Tarduno, a professor of geophysics at the University of Rochester, says scientists will have to reconsider the forces that affect Earth’s geomagnetic field.
“They’re talking changes on much shorter timescales — a million years or less — and big changes in the dipole components of the magnetic fields,” Tarduno says. “That’s actually a challenging idea. If it’s correct, that really makes us have to think differently about the dynamo and how those changes could actually happen.”
