Are the poles reversing? Earth’s magnetic field 10 times more volatile than expected

06-07-20 04:22:00,

A study by researchers from the UK and US shows that the Earth’s magnetic field, which protects it from the Sun’s destructive solar flares, may change direction 10 times faster than previously thought. 

The study shines light on the liquid iron flowing almost 2,000 miles below the Earth’s surface and how it influences the movement of the Earth’s geomagnetic field. 

The Earth’s molten metal outer core creates electric currents that charge the planet’s magnetic field. 

The magnetic field is crucial to life on Earth as not only does it help us with things such as navigational systems, but also protects us from radiation from outer space.

The study, published in Nature Communications, details how researchers discovered that our understanding of the magnetic field is flawed, and shows that changes in the direction of the magnetic field can be up to 10 times faster than the fastest ever recorded. 

The work involved combining computer simulations of the field generation process with a recently published reconstruction of time variations in the Earth’s magnetic field spanning the last 100,000 years.

The work revealed a sharp change in the direction of the magnetic field around 39,0000 years ago. The shift, at 2.5 degrees per year, was much faster than previous estimates.

The shift was preceded by the global Laschamp excursion, a short reversal of the Earth’s magnetic field roughly 41,000 years ago.

There have been many times in history when the Earth’s magnetic poles have reversed, and we know this because of the magnetic makeup of certain ancient rocks which show metals with different polarizations. 

In general, we don’t know much about the effects of such a flip, except that once it is completed, the needle on a compass will tell us that north is south and that south is north. 

This is important as such rapid changes are associated with a local weakening of the magnetic field,

Magnetic Poles Are Moving Rapidly as Never Before – Precursor to a Pole Shift? | Armstrong Economics

The magnetic poles on the Sun flip about every 11 years. Since nobody lives there, we really have no idea what the effects would be. On Earth, the major pole shifts that are permanent tend to be in the 720,000 years range. So once again, there was nobody around to record what really happens. I have previously warned that the North Magnetic Pole was moving away from Canada and headed in the opposite direction toward Europe.

For most of the 1900s, the physical North Pole was moving westwards around 10 cm each year towards Canada’s Hudson Bay. Then all of a sudden, in 2000, it changed direction moving 75 degrees eastwards and began moving east at a rate of around 17 cm annually. Nobody has ever witnessed such a change. This is completely unprecedented! Now the North Magnetic Pole is moving rapidly and erratically. Today it is now moving at a pace of 55km PER YEAR!!!!! This is creating a real crisis because the entire world GPS system was based upon a fairly stationary location for the North Pole.

The North Pole was previously in Hudson Bay about 54,000 until 48,000 years ago at 60 N and 83 W. Perhaps it is like lightning and just never strikes twice in the same spot. Now it is instead moving toward the British Isles according to NASA. Magnetic poles are defined in different ways but are commonly understood as positions on the Earth’s surface where the geomagnetic field is vertical. These north and south positions, called dip poles, do not need to be opposite of each other. In 1831, James Clark Ross located the north dip pole position in northern Canada. Natural Resources Canada (NRCan) tracked the North Magnetic Pole, which is slowly drifting across the Canadian Arctic, by periodically carrying out magnetic surveys to reestablish the Pole’s location from 1948 to 1994. An international collaboration, led by a French fundraising association, Poly-Arctique, and involving NRCan, Institut de Physique du Globe de Paris, and Bureau de Recherche Geologique et Miniere, added two locations of the North Magnetic Pole in 2001 and 2007. The most recent survey determined that the Pole is moving approximately north-northwest at 55 km per year.

First of all, there are two types of pole shifts.

Flipping of the Poles Rapid of Gradual? | Armstrong Economics

QUESTION: Mr. Armstrong; I read your Mayan report and it was fascinating. Do you think that these strange anomalies of places that are cool experiencing hot summers and where it should be hot have been getting cool are a prelude to climate change that may be the preparation for the flipping of the poles?

EK

ANSWER: Nobody knows for sure. There are a number of scientists who are very concerned that we are overdue for the reversal of the poles. Nobody really knows the consequences since we are talking about a period beyond recorded history. One theory is that the magnetic field is what shelters us from the worse of the sun. The magnetic field has been declining in magnitude. This is what many fear is the real cause behind the appearance of climate change.

We were given the data to run it through our computer and it came up with a cycle of 720,000 years. We are clearly overdue and how do you measure that is hard to say – weeks, months, years, decades, or centuries? It has been postulated that such a flip will be devastating for our shield against harmful radiation from the sun will be diminished. Some have even raised the issue that this could be a factor in mass extinctions.

What I can say is that based upon our models, the pole flip will be rapid, not gradual. The prelude may appear gradual as we see now with a 5% decline per century. However, we will cross an invisible line and then it will flip instantaneous not gradual. It will act like a pot of boiling water. It will be no means be a linear progression.
