Earth’s due for Magnetic Pole Reversal

According to Cosmos online, dutch scientists believe that a magnetic pole reversal is imminent for Earth and we shouldn’t take this situation lightly. The magnetic field is gradually reducing which will leave the earth venerable to the solar winds. This is troubling due to NASA’s recent discovery that solar winds and solar storms will peak in 2012 (see previous post NCAR Predicts solar peak in 2012)

SYDNEY: A reversal of the Earth’s magnetic poles could happen sooner than we think, according to Dutch scientists who report that the planet’s magnetic field is becoming gradually less stable.

A reversal could affect everything from navigation and communications equipment to the composition of the atmosphere, say experts.

The report, published today in the U.K. journal Nature Geoscience, found that reversals have been far more common in the last 200 million years than they were deep in the planet’s history.

Wandering poles

Researchers, led by Andrew Biggin of the University of Utrecht in the Netherlands, made the discovery by analysing rocks formed between 2.45 to 2.82 billion years ago.

The story of the Earth’s magnetic field is written in rocks over time. Because these rocks become ‘magnetised’ at the time of their formation, scientists can discover which direction the poles were facing and how strong the Earth’s magnetic field was at that time.

The magnetic poles wander around the vicinity of the geographic poles all the time – the north magnetic pole currently resides in the Canadian Arctic. However, at relatively regular intervals throughout the 4.5 billion year history of the planet, the magnetic poles have flipped completely. A few thousand years before a reversal, the magnetic field gradually gets weaker; something which could cause problems for inhabitants of the planet.

“The Earth’s magnetic field is important for shielding the atmosphere, and us, from damage caused by the solar wind,” explained Biggin. “It’s also used by us and other species for navigation”. An increase in solar wind would disrupt communications equipment and power grids.

Current records suggest that we are long overdue for our next reversal, he said. “On average, there is a reversal around every 400,000 years, but this varies a lot.” The geological record suggests that the last reversal was around 800,000 years ago.

Furthermore, there is already evidence to show that the field has been weakening over the last few centuries – some archaeological remains suggest that the field was far stronger in the time of the Roman Empire, some 2,000 years ago.

Don’t throw away your compass

Don’t throw away your compass just yet though – major changes may not even happen in our lifetimes. “The reversal process is very unpredictable,” said Biggin. “We could be heading into a reversal in the next few centuries, or we might be waiting another million years”.

Even then, reversal is a slow process, which can take some thousands of years to complete.

But what about the effect on living organisms? Another paper, published in Nature in March suggested that some species that rely on the field for navigation or orientation have taken a knock from pole reversals in the past.

Author David Gubbins, of the University of Leeds in England, said that some single-celled organisms that relied on magnetism to tell up from down likely went extinct during past reversals. Human beings have survived reversals in the past, however, added Gubbins, “so we are likely to come through the next one unscathed.”

Magnetic Pole reversal may lead to the END of Human Civilization

Some scientific computer models show that the last magnetic pole reversal lead to the end of the dinosaurs and what is saying that this magnetic pole reversal wont do the same for humans? Who will save us? Many think Aliens will save our civilization but maybe we have to save ourselves…

According to some computer scientists working together with a group geophysicists and astrophysicists, Earth and Sun both will go through a process of Magnetic Pole Reversal in 2012. This last happened millions of years back when the Dinosaurs disappeared. A private research and analysis company in Hyderabad is predicting a major upheaval in 2012.

Magnetic Pole reversal is a process when North Pole and South Pole reverse positions. When this happens, at some point of time Earth’s magnetic field reaches zero Gauss which simply means, Earth at that point of time has zero magnetism. When this coincides with a eleven year cycle of Sun’s Polar reversal, a major problem arises.

According to the Hyderabad Computer Model, the polar reversal of Earth and Sun can cause the following serious problems other than electronic malfunction, migrating birds losing sense of direction and so on:

– the immune system of all animals including the humans will weaken substantially

– the earth’s crust will experience increasing volcanoes, tectonic movements, earthquakes and landslides

– Earth’s Magnetosphere will weaken and Cosmic Radiation from Sun will increase many folds making radiation hazards like cancer and so on inevitable

– Large Asteroids will be drawn towards the Earth

– the Earth’s gravitational field will experience a change though no one knows how it will change

If you add up all these possible devastating scenarios, you can easily see that in simple words, Earth may become not suitable for human civilization by 2012 and those who live on or near earth’s crust.

The organisms living deep in the Earth well below the crust will survive. Without any intervention in this natural process, millions of years later we will see some other form of intelligent or large life forms are dominating the earth on its crust.

A large number of Extra-terrestrial UFO sightings in recent days, according to many UFO researchers in the world is connected to saving the human civilization form extinction. It is possible in absence of our knowledge they are trying to provide a counter measure that can save the human civilization.

If this model is true, the only way for us to survive will be to take our civilization well below the Earth’s crust or move to another planet. It may have happened to Mars millions of years back.

Recent extra-terrestrial UFO activities (in the last 100 years) point out that someone out there knows that something severe will happen. They may be creating a scenario where they can silently help us or even remove us to an unknown destination.
