The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal. However, a new study that pieces together evidence stretching back 9,000 years, suggests that the current changes aren’t unique, and that a reversal may not be in the cards after all.
The Earth’s magnetic field acts as an invisible shield against the life-threatening environment in space, and solar winds that would otherwise sweep away the atmosphere.
However, the magnetic field is not stable, and at irregular intervals at an average of every 200,000 years polarity reversals happen. This means that the magnetic North and South poles swap places.
During the past 180 years, Earth’s magnetic field strength has decreased by about 10 percent. Simultaneously, an area with an unusually weak magnetic field has grown in the South Atlantic off the coast of South America.
This area, where satellites have malfunctioned several times due to exposure to highly charged particles from the sun, is called the South Atlantic Anomaly. These developments have led to speculation that we may be heading for a polarity reversal. However, the new study suggests this may not be the case…
“We have mapped changes in the Earth’s magnetic field over the past 9,000 years, and anomalies like the one in the South Atlantic are probably recurring phenomena linked to corresponding variations in the strength of the Earth’s magnetic field,” says Andreas Nilsson, geologist at Lund University.

The results are based on analyses of burnt archaeological artifacts, volcanic samples and sediment drill cores, all of which carry information about the Earth’s magnetic field. These include clay pots that have been heated up to over 580 degrees Celsius, volcanic lava that has solidified, and sediments that have been deposited in lakes or in the sea.
The objects act as time capsules, and carry information about the magnetic field in the past. Using sensitive instruments, the researchers have been able to measure these magnetizations and recreate the direction and strength of the magnetic field at specific places and times.
“We have developed a new modeling technique that connects these indirect observations from different time periods and locations into one global reconstruction of the magnetic field over the past 9,000 years,” says Andreas Nilsson.

By studying how the magnetic field has changed, researchers can learn more about the underlying processes in the Earth’s core that generate the field. The new model can also be used to date both archaeological and geological records, by comparing measured and modeled variations in the magnetic field. And reassuringly, it has led them to a conclusion regarding speculations about an imminent polarity reversal:
“Based on similarities with the recreated anomalies, we predict that the South Atlantic Anomaly will probably disappear within the next 300 years, and that Earth is not heading towards a polarity reversal,” concludes Andreas Nilsson.
It’s probably just another scientific lie… [PNAS, Phys.org]

A big magnet like our earth’s core aligns with the other magnets in our solar system. And like any permanent magnet, it cannot switch poles! And its north pole will always point up, if looking at the globe as we do with the USA and Europe on top. But the connection between the core and the crust is soft like bubble gum. Basically, the crust just floats on the core. As Nibiru approaches, and shoots past the earth, it jerks the big magnet around, and does it so quickly, the crust breaks loose from the core and settles in a new position with respect to the core. But the core will right itself with its north pole up again. But all the continental plates will be in a new position. So as the Bible says, a new heaven and a new earth. All the stars will be in new places with respect to crust. Guess west becomes south.
I think that poles will reverse based on some bible comments. are you ready to meet your maker?
A magnetic pole reversal means that a compass that once read north will read south & visa versa after.
That said other things are currently happening that are endangering our lives.
When the poles flip, every plate (geological) will suddenly go the other way. This will cause Earthquakes (Big ones), tsunamis, volcanic eruptions…in straight speak – Hell on Earth.
AND add the Sun at its lowest output since the late 1700’s (causes energy to excite magma), colder temps (loss of crops) and you get a ‘rewrite’ of Humanity!
9,000 years … Nine Thousand years…the Earth is 4.2 BILLION +- old.
Get real.
Didn’t you read it correct? They still got digital copies of what happened 9000 years ago ahaha…
AHHAHAHAHAHA !
