BREAKING NEWS: More Signs Of Coming Pole Shift

A moving viscous flow within the Earth’s molten iron core has been discovered by scientists using the latest satellite data that helps create an ‘x-ray’ view of the planet.

Lead researcher Dr Phil Livermore, from the University of Leeds, said: “The European Space Agency’s Swarm satellites are providing our sharpest x-ray image yet of the Earth’s outer core. We’ve not only seen this moving flow clearly for the first time, but we understand why it’s there.”

“We can explain it as an accelerating band of molten iron circling the North Pole, like the moving stream in the atmosphere,” said Dr Livermore, from the School of Earth and Environment at Leeds.

Because of the outer core’s remote location under 3,000 kilometers of rock, for many years scientists have studied the Earth’s outer and inner core by measuring the planet’s magnetic field – one of the few options available.

Previous research had found that changes in the magnetic field indicated that iron in the outer core was moving faster in the northern hemisphere, mostly under Alaska and Siberia. But new data from the Swarm satellites has revealed these changes are actually caused by a moving flow moving at more than 40 kilometers per year. This is three times faster than typical outer core speeds and hundreds of thousands of times faster than the speed at which the Earth’s tectonic plates move.

The European Space Agency’s Swarm mission features a trio of satellites which simultaneously measure and untangle the different magnetic signals which stem from Earth’s outer and inner core, mantle, crust, oceans, ionosphere and magnetosphere. They have provided the clearest information yet about the magnetic field created in the core.

The study, published today in Nature Geoscience, found the position of the moving flow aligns with a boundary between two different regions in the outer core. The jet is likely to be caused by liquid in the core moving towards this boundary from both sides, which is squeezed out sideways.

Co-author Professor Rainer Hollerbach, from the School of Mathematics at Leeds, said: “Of course, you need a force to move the liquid towards the boundary. This could be provided by buoyancy, or perhaps more likely from changes in the magnetic field within the outer core.”

Rune Floberghagen, ESA’s Swarm mission manager, said: “Further surprises are likely. The magnetic field is forever changing, and this could even make the moving flow switch direction.

“This feature is one of the first deep-Earth discoveries made possible by Swarm. With the unprecedented resolution now possible, it’s a very exciting time – we simply don’t know what we’ll discover next about our planet.”

Co-author Dr Chris Finlay, from the Technical University of Denmark said: “We know more about the Sun than the Earth’s core. The discovery of this jet is an exciting step in learning more about our planet’s inner workings.”

The Causes of Heating and Cooling of Earth’s Core and Climate Change

Ongoing studies supported by the NSF (National Science Foundation) indicate a connection between submarine troughs (rifts), Earth’s mantle, and Earth’s outer core. Furthermore, new research indicates the shifting of magnetic flux via Earth’s magnetic field, has a direct and symbiotic relationship to Earth’s outer core, mantle, lithosphere, and crust.

As a living entity, Earth fights for its survival. If internal or external events begin to throw Earth out of balance i.e. orbital, tilt, or magnetic alignment – it begins to correct itself. When oceanic tectonic subductions occur, it cools the mantle and outer core. To balance this shift in temperatures, the Earth’s core increases heat and as a result releases what is known as “mantle plumes”. These plumes filled with super-heated liquid rock float up to the ocean bottom surface.

This action both cools the outer core and heats the oceans. As a result of heated oceans, we get tropical storms and various forms of extreme weather. When troughs, subduction zones, and rifts shift, as a result of convection, earthquakes, tsunamis, and volcanoes occur.

What makes this all work is the Earth’s magnetic field. Right now the magnetic field is weakening significantly. This will continue until it reaches zero point, at which time there will be a full magnetic reversal. Until this time, we will witness magnetic north bouncing in the northern hemisphere. Closer to the moments of a full reversal, we will see magnetic north drop down to/then below the equator.

As a result of a weakened magnetic field, larger amounts of radiation via charged particles such as solar flares, coronal mass ejections, gamma rays, and galactic cosmic rays – are more abundantly reaching Earth’s atmosphere and having a heightened reaction with Earth’s core layers. This is what causes looped reaction. Radiation heats the core layers, the outer core reacts by producing ‘mantle plumes’, which causes crustal fracturing, which then causes earthquakes, volcanoes, heated oceans – all of which cools the outer core.

This seemingly repeating loop will continue until the Earth will once again find its balance. Until then, we can expect naturally occurring earth changing events which will produce the loss of mass in some parts of the world, and emergence of mass in other parts. Maybe this is the time to change the things we can (attitude, environment, community, self, surroundings), one would be a fool not to apply themselves within their means – but then there is the time to loosen up a bit, know what is happening is just part of a process.

Just as the Earth, we humans can just keep on trucking, and maybe, just maybe, some will simply ‘enjoy-the-ride’.
