Articles in Magnetic Pole Shift
This is meaningful, because for every animal that does get studied in this way (because scientists are curious about how they navigate from A to B), there will be dozens of other animals that use the same bio-technology but are not studied. Consequently, the butterfly effect from a magnetic pole shift could be massive and lead to major ecological breakdowns around the planet.
Researchers at Oregon State University report their studies suggest salmon use magnetism to find their way to their home rivers during spawning migrations.
…Writing in the journal Current Biology, the researchers suggest salmon find those home rivers by sensing the river’s unique magnetic signature.
…”These results are consistent with the idea that juvenile salmon imprint on [i.e., learn and remember] the magnetic signature of their home river, and then seek that same magnetic signature during their spawning migration,” Oregon post-doctoral researcher Nathan Putman said.
Most salmon make the round-trip migration, which …
I’m not talking ordinary solar storms. I’m talking a once-in-every-40-thousand-years solar storm. That’s something we have no written record of, and given how little we know about our Sun, it is quite possible that it is capable of sending such a super-massive solar storm our way when it feels like it.
So, if a super-massive solar storm – say ten times more powerful than the Carrington Event – could one day occur, could it be powerful enough to flip our magnetic poles?
That’s a question for a physicist, not me. But I did find these two snippets:
It is conceivable that a very large cosmic ray barrage could induce a ring current magnetic field large enough to reverse the geomagnetic polarity at the Earth’s surface. Particle -induced field reversals have been simulated in the laboratory by injecting large quantities of charged particles into a magnetic field (Golden et al., 1981). At a certain …
Orthodox scientists, especially those who debunk the idea of a magnetic pole shift in 2012, need to keep up with the latest research and perhaps change their tune. Newly published data has confirmed that the Laschamp event was not an excursion, but actually a full-blown magnetic reversal that occurred very quickly compared to what scientists generally believe.
Some 41,000 years ago, a complete and rapid reversal of the geomagnetic field occurred …data obtained by the research team formed around GFZ researchers Dr. Norbert Nowaczyk and Prof. Helge Arz, together with additional data from other studies in the North Atlantic, the South Pacific and Hawaii, prove that this polarity reversal was a global event. Their results are published in the latest issue of the scientific journal Earth and Planetary Science Letters.
Evidence for excursions that have been discovered indicate that they occur at least every 65,000 years. If more are discovered then …
If you ask me What could an ancient civilisation have predicted for Dec 21, 2012?, then my answer is a comet, either flying by or crashing into us, or a solar storm. If you take the predictive element out of the 2012 equation, my best guess is a magnetic pole shift, or crustal displacement, or both. Here’s an overview of my hypothesis, including some recent science news.
Magnetic Pole Shift
Scientists tell us that our magnetic poles have reversed in the past, and that they will again. They 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.
If a reversal involves a dramatic lessening of our geomagnetic field’s strength, then basically …
Certain neurons in pigeon brains encode the direction and intensity of Earth’s magnetic field, providing the common birds with an internal global positioning system, according to a new study.
The findings in the study, published in the latest Science Express, likely apply to other birds as well.
“We have found cells in the (pigeon) brain that signal the direction, intensity and polarity of an applied magnetic field,” co-author David Dickman, a Baylor College of Medicine neuroscientist, told Discovery News. “These three qualities can be used by the brain to compute heading information, like a compass, and latitude on the Earth surface (location between the magnetic North and South Poles).”
“It is possible that magnetic intensity could also be used to give the bird longitude (East-West location) through learned associations of differing regional variations along the Earth surface,” he added. “Together, these cells could form the basis of determining heading direction and position according to a …
Planetary magnetic fields are generated by flows in the hot, liquid iron cores of the planets. Measurements made by Mariner 10 in 1974/75 showed that Mercury also has a magnetic field. According to the standard models, the dynamo effect in its metal core should generate similar field strengths to those on Earth. Mercury’s magnetic field is 150 times weaker than that of our planet, however. This has recently been confirmed by the Nasa space probe Messenger.
How can the large discrepancy in the field strength be explained? This question has now been answered by a group headed by Karl-Heinz Glassmeier at the Technische Universität Braunschweig. The solar wind – a constant stream of charged particles – plays a significant role. At an average distance from the Sun of only 58 million kilometres – around one third of the distance of the Earth – Mercury is much more exposed to these particles.
Again, this information comes from Electric Universe expert James McCanney, via SOTT.
So the idea here is that the entire Earth-Moon-Sun system works as a whole to generate the Earth’s unique magnetic field. The solar wind, the Moon, the ionosphere layers (which in turn cause the jet streams), the crustal layer, the molten layer and the very core of the Earth are all part of this system. Each layer builds on itself. The interesting part of all of this is that it’s not just the interior of the Earth that forms the magnetic field, as most geologists suppose, the system is ultimately at the mercy of external forces in the solar system (the Sun and the Moon predominantly). McCanney believes external forces are likely to cause the periodic shifts in the Earth’s magnetic orientation.
And what sort of external force could cause a magnetic pole shift?
According to McCanney there would have to …
“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.” This could be local, or global, they don’t seem sure. But it is certainly something scientists previously did not believe possible.
Why build bunkers when you can protect an entire city with a massive dome?
The concept would supposedly keep the city safe from a category-5 hurricane.
Tunguska was not the only explosion of its type last century – there’s actually a list of them at Wikipedia. A good candidate to add to that list is a powerful blast that struck British Guyana in 1935. An expedition “reported seeing an area some miles across where the trees had been broken off about 25 feet above their bases“, while numerous people witnessed a “large meteoroid/small asteroid entry“. One day a town or …
The famously predicted “earth changes” could finally be in effect. As of now the various natural disasters could just be a statistical blip, but give us a few more (watch this week, and June 1 through July 1) and not only will many prophets appear spot on, but the world will start to panic – although I’m unsure of any short-term measurement for this, except for polling folk.
So if it continues, what is the cause??
a) Patrick Geryl suggests the Sun will be becoming increasingly erratic, leading to a crustal displacement in 2012.
b) The next solar maximum could be big, and increased flares and CMEs could cause all sorts of bother to our planet. Experts keep changing their minds over how big or small the next maximum will be…
c) I’ve noticed an increased in likelihood of events around full moons and especially eclipses. Gravity between the Sun, Moon and Earth cannot …
Numbers can be presented in many ways. But given that the movement of the magnetic north pole is in a singular direction, all that matters is the speed. This graph is compelling:
Unlike climate change data, this is the entire available data, no selective windows here.
This photo is doing the rounds:
It looks photo-shopped to me. And it looks bigger than anything of such uniform shape would be. And I figure South Pole folk would immediately recognise whatever is was. Still, has an un-spammy source:
Meanwhile TV physicist Michio Kaku was interviewed by CNN, where he mentions the 10-inch ground swell at Yellowstone, which may or may not be indicative of an eruption in the near future. When Yellowstone blows, it will kill with a 500 mile radius, and his advice to people is “run”.
This story has caused a big stir online, leading many people to jump to the conclusion that the magnetic poles are shifting, and doom is near.
The runways have large numbers visible to the pilots when they land the planes. The numbers are used for the pilots to line up their compasses for a safe decent and landing.
The earth’s magnetic poles have changed so much that the 180 degree reading is now 190 degrees, and this could lead to problems, especially as the poles continue to move. Tampa Airport has been forced to shut down and re-do all these numbers on the runways.
Suddenly there is debate about what harm a pole shift could cause, and very little information about whether the poles really are shifting. Here’s some quick info:
The magnetic North Pole has been on the move ever since we first pinpointed it, and is currently …
Suddenly a candidate for 2012 becomes more feasible… if only we can work out a way the Mayans could have predicted it!
Previous evidence for a high-speed pole shift (in 1995) was dismissed by most scientists because it was an anomaly. Now that more evidence has emerged, it is time for geologists to accept that a magnetic pole shift can affect us without notice.
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. (Read the full news item at Wired.com.)
Still scientists are clinging to a slow reversal, rather than an on/off switch. 53 degrees …
New research suggests that our magnetic poles have sometimes been at the equator. Even more interesting for anyone who thinks a pole shift is possible in 2012 – this switch occurred multiple times in a 50 million year period. And there is lack of intermediary polar locations – they were either at the poles we have today, or at the equator. This suggests a sudden switch.
Any sudden movement of the magnetic poles could cause problems, but I’m not aware of any reason why the new pole location matters – the change and the speed of the change are the important factors. The change is important because anything that currently involves the North pole actually being at the North pole will fall over. That would primarily be locational tools that humans use (GPS, compasses). The speed is critical. Slow is preferable, because fast will most likely leave us without a shield against …
There has been considerable difficulty trying to determine if a magnetic pole shift will occur in 2012. The underlying problem is that orthodox science has not been able to work out how our planet’s magnetic field ticks, and all we have seen is guesswork.
According to Wikipedia:
There is no clear theory as to how the geomagnetic reversals might have occurred. Some scientists have produced models for the core of the Earth wherein the magnetic field is only quasi-stable and the poles can spontaneously migrate from one orientation to the other over the course of a few hundred to a few thousand years. Other scientists propose that the geodynamo first turns itself off, either spontaneously or through some external action like a comet impact, and then restarts itself with the magnetic “North” pole pointing either North or South.
Current theories are not capable of producing predictions of when the next reversal might occur. …
Dan Lathrop has built his fourth “baby Earth”, a model designed to help better understand our planet’s magnetic forces. The previous version was just two feet in diameter, and failed to generate a magnetic field of its own. The new model is ten feet across, and will spin at 145 kph. Dan and his team are hoping that this will be big enough to create a magnetic field, and lead to some understanding of how this aspect of Earth ticks.
Of special interest is magnetic pole shifts – what causes them, and when will the next one be. In an interview Dan suggests that we would have a century or two up our sleeves to prepare. Hopefully Dan’s experiment will have results prior to 2012…
