Today’s article will come as no surprise to Science Of Cycles readers. There have been several articles SOC published regarding this issue going back to 2012. One of the highly contested questions regarding the pole shift…is ‘where’ on the time line are we measured as of today. I address this in a few of my previous articles. A significant conveying influence to the makings of a magnetic pole reversal is the deluge of cosmic rays which has an effect on the Earth’s mantle and outer core.
The process of convection is amplified which can produce an imbalance that could cause a ‘bulge’, also can produce an acceleration of mantle plumes – which in-turn causes heating of the oceans. These processes can have an effect of Earth’s dipole which creates the North and South magnetic direction.
Furthermore, my research presents a hypothesis suggesting the influx of cosmic rays during extended solar minimum cycles which could range from 40,000 years to 700,000 years – each being its own cycle within a cycle, could be a contributing factor in historic global extinctions.
As you might have guessed, a large part of my research is the study of cycles, hence, my company’s title; Science Of Cycles. I will be presenting my article titled “Cosmic Rays Role in Historic Extinctions” tomorrow, which will comprise the latest research published on December 6th 2018.
As Earth’s magnetic shield fails, so do its satellites.First, our communications satellites in the highest orbits go down. Next,astronauts in low-Earth orbit can no longer phone home. And finally, cosmic rays start to bombard every human on Earth.
If Earth’s magnetic field were to decay significantly, it could collapse altogether and flip polarity – changing magnetic north to south and vice versa. The consequences of this process could be dire for our planet. Most worryingly, we may be headed right for this scenario.
‘The geomagnetic field has been decaying for the last 3,000 years,’ said Dr. Nicolas Thouveny from the European Center for Research and Teaching of Environmental Geosciences (CEREGE) in Aix-en-Provence, France. ‘I fit continues to fall down at this rate, in less than one millennium we will be in a critical (period).’
Dr. Thouveny is one of the principal investigators on the five-year EDIFICE project, which has been running since 2014. Together with his colleagues, he has been investigating the history of Earth’s magnetic field,including when it has reversed in the past, and when it might again.
Cosmic rays: Our planet’s magnetic field is predominantly created by the flow of liquid iron inside the core. It has always been a feature of our planet, but it has flipped in polarity repeatedly throughout Earth’s history. Each time it flips – up to 100 times in the past 20 million years, while the reversal can take about 1,000 years to complete – it leaves fossilized magnetization in rocks on Earth.
By taking cores – or columns – of sediments from the seafloor, like a long straw that can extend down up to 300 meters with the help of a drill, we can look back in time and see when these reversals occurred. Dr. Thouveny and his team looked at two particular forms of elements that allowed them to probe the history of our planet’s magnetic field in greater detail.
For a polarity reversal to occur, the magnetic field needs to weaken by about 90% to a threshold level. This process can take thousands of years, and during this time, the lack of a protective magnetic shield around our planet allows more cosmic rays – high-energy particles from elsewhere in the universe – to hit us.
When this happens, these cosmic rays collide with more and more atoms in our atmosphere, such as nitrogen and oxygen. This produces variants of elements called cosmogenic isotopes, such as carbon-14 and beryllium-10, which fall to the surface. And by studying the quantities of these in cores, we can see when polarity reversals took place.
