Geomagnetic excursion

Since 1831, the magnetic north pole has moved some 2,300 kilometres. At a rate of aproximately 12 kilometers per year. But in last 10 years that movement has increased to 55 kilometres per year. Increasing speculation that a magnetic flip is on the cards. On average, the earths magnetic flips every 200,000-300,000 years. With the last last magnetic flip occurring some 780,000 years ago.

A much more common event is called a Geomagnetic excursion. A period in which earths magnetic field becomes highly chaotic that can last 500–3000 years. The last geomagnetic excursion was the Laschamp event, dated at around 40,000 years ago, during the end of the Last Glacial Period, which caused a temporary reversed field, that was only 5% of the earths normal magnetic field strength.

A reduced magnetic field not only allows greater amounts of radiation to reach the surface of the Earth but also allows the charge in the earths ionosphere to greatly increase from solar electromagnetic radiation. In the past, solar storms have caused power grids to fail. With a magnetic field some 20 fold weaker than it is today, solar electromagnetic radiation could have far greater impact on electronics than ever before.

The only constant in nature is change. Should we ignore the potential of nature to change. Or should we invest into safeguards that can increase the potential of life to continue should we face detrimental changes to our environment.

That pole has been gradually shifting; but some are calling this natural shift 'global warming'. We humans haven't experienced an extreme shift in our lifetimes..but it could happen. Frozen Marigolds/margaritas found in the mouths of Arizonans....

"Frozen Marigolds/margaritas found in the mouths of Arizonans" lol

There might be correlation between sun and earth magnetism which rule out global warming.

Yes its a 1 in 500 lifetimes event. More probable than our house burning down. Yet we don't insure against it. Our minds likes to see permanancy in all things. But nature is a different animal.

Thank you for replying. This planet is highly monitored, as designed by others millions of years in advance of us. Human bleats regarding 'we will all be dead in 10 years' should be ignored. Humans know nothing regarding this petri dish Time Space Illusion planet designed by others, their purpose or reason for incarnating.

A complete discussion on a compression event which becomes more likely as the Earth's magnetic field continues to collapse. Most measurements I have seen say we have lost around 20% of our magnetic field over the last couple of hundred years (1800s).

The videos are not for everyone as they contain "SCIENCE" but nevertheless they are interesting. youtu.be...

There is no correlation between magnetic pole shifts and climate.

The last time that Earth's poles flipped in a major reversal was about 780,000 years ago, in what scientists call the Brunhes-Matuyama reversal. The fossil record shows no drastic changes in plant or animal life. Deep ocean sediment cores from this period also indicate no changes in glacial activity, based on the amount of oxygen isotopes in the cores.

Yet we witness abandoned Mayan cities. Stories of great flood in India. Old Egyptian Kingdom starving. Why did the God's turn their back on all of them!. Globalization has decompartmentalized society. Making it far more fragile than ever before. If it cannot handle a little germ from wuhan. Its not likely to handle problems of a far more significant nature.

So we need implement fail-safe systems that adapt rather than break with nature. Military already hardens their equipment from emp attacks so the technology already exists to protect machinery from another geomagnetic excursion. The only thing people really fear is ignorance. By alleviating ignorance we can alleviate fear.

I understand what you are saying.

In the past, solar storms have caused power grids to fail. With a magnetic field some 20 fold weaker than it is today, solar electromagnetic radiation could have far greater impact on electronics than ever before.

I wouldn't be too sure about that.

First, "solar storms" otherwise known as geomagnetic storms, do not have much effect on electronics unless they happen to be plugged into the power grid.

Second, a geomagnetic storm, a thing that really can cause problems with power grids, is series of fluctuations in Earth's magnetic field, it is not an EMP. When a CME encounters the magnetosphere it causes it to "wiggle." These "wiggles" cause induced electrical currents in long conductors (like power lines). It would actually seem that the weaker the Earth's magnetic field is, the weaker those currents would be. With no geomagnetic field, there would be no geomagnetic storms.

While some protection from solar and cosmic radiation is provided by the magnetosphere, the atmosphere itself makes a very good shield. If the geomagnetic field failed entirely there might be a slight increase in global cancer rates but not a lot.

Thanks for input 727Sky. NASA has projected that the next solar cycle will be 30-50% lower than previous putting it at Dalton minimum levels. Which suggests to my mind that the energy from suns and earths magnetic field have a common source.

Implying that perhaps there is no increased danger from flares because both the strength of sun's and earths magnetic fields are reducing at the same time. Equalizing the dangers somewhat.

Energies from outside our solar system can be more significant than our sun, but luckily, extremely rare here.

NASA has projected that the next solar cycle will be 30-50% lower than previous putting it at Dalton minimum levels.

The prediction for solar cycle 25 is that it will be more or less the same as solar cycle 24.

The panel agreed that Cycle 25 will be average in intensity and similar to Cycle 24.

The strength of the Earth's magnetic field has been declining for several hundred years (and it is still stronger than it has been in the past 50,000). Solar activity, not so much.

a reply to: Phage

Thanks Phage, I really didn't understand the distinction between solar and geomagnetic storm. It makes sense that geomagnetic storm would be lessened if strength of earth magnetic field continues to diminish.

Makes the entire thread pointless. Oh well. Hopefully it might calm the nerves of people that think otherwise

You are a real benefit to ATS, Phage. Very much appreciated

Hi glend if you interested in learning a lot about the Grand minimum in layman's terms you can watch this video

Then browse the hundreds of video on the channel then if still really interest join them on the web page for more indepth knowledge suspicious 0bservers

Extremely useful information - FYI not affiliated in way with them just passing on a good free source.
