Earth’s magnetic field flipped 425,000 years ago. The results were dramatic

New research has shown that the Earth’s crust of a global period, 000,000 years ago, has the opposite effect on the Earth’s magnetic field.

According to radiocarbons preserved in ancient tree rings, valuable climate breakdowns, mass extinctions, and changes in human behavior over the centuries can also be directly linked to the end times when the Earth’s magnetic field changed its polarity.

The research team named the period the Adams Transitional Geomagnetic Event or Adams Event, after the scientific author Douglas Adams, who publicly gave the number 42 the final answer to life, the universe and everything.

“For the first time, we have been able to determine the timing of the last magnetic pole switch and the exact date of the environmental impact,” said Chris Terni, a seismologist at the University of New South Wales in Australia.

“The findings were made possible by ancient New Zealand’s Kauri trees, which have been preserved in silt for 400,000 years. We can use ancient trees, and by date, spikes in the atmospheric radiocarbon layer due to the collapse of the Earth’s magnetic field.”

This most recent period of magnetic resonance is known as the lumpsamp event, and is what we call geographic luminosity. This happens when the planet’s magnetic poles change places for a while before returning to their original position. It is one of the most well-studied of the Earth’s magnetic field phenomena, recorded by ferromagnetic minerals.

It happened about 41,000 years ago, and lasted about 800 years. The impact of this event on life on the planet was unclear, however – so when scientists unearthed the ancient Kauri tree (Agathis ust Stralis) In 2019 those who were alive during this period had the opportunity to learn more.

This is because the trees record the atmospheric activity in the annual growth ring. In particular, carbon-14, or radiocarbon, can reveal a lot of information about spatial activity.

Radiocarbons on Earth occur only in trace amounts compared to naturally occurring carbon isotopes. It forms in the upper atmosphere under the bombardment of cosmic rays from space. When these rays enter the atmosphere, they interact with local nitrogen atoms to react with the radiocarbon-producing molecule.

As global rays continue to flow through space, the Earth receives a more or less constant supply of radiocarbon. Therefore, the spike in radiocarbon in tree rings tells us that the amount of radiocarbon in the earth was higher during that year.

When the Earth’s magnetic field weakens, as it did during the Lashc MP event, more cosmic rays enter the atmosphere to produce more radiocarbon. Because of this, scientists have previously been able to confirm that the Earth’s magnetic field has weakened by about 28 percent of its normal strength over that 800-year period.

However, the Kauri tree allowed the research team to study the years of the Lashmapmp incident. They discovered that the Adams event took place about 42,200 years ago and that the magnetic field was at its weakest point. Before Lashchamp event.

“Earth’s magnetic field only strengthened by 0-6 percent during the Adams event,” Terni explained. “We essentially had no magnetic field – our cosmic radiation shield was completely removed.”

During this time, the Sun’s magnetic field would also have been weakened several times, as it too, as part of its regular cycle, experiences magnetic opposite. These periods see sunspot and flame activity, but the sun’s magnetic field also protects the earth from cosmic rays – so, during this solar minima, cosmic ray bombardment would have increased again.

This weak magnetic field would have triggered significant changes in the Earth’s atmospheric ozone with dramatic consequences, including electric storms and spectacular auroras and climate change around the world.

“Obscure radiation from space scatters air particles into the Earth’s atmosphere, separates electrons and emits light – a process called ionization,” Terni said.

“Ionized air ‘fries’ the ozone layer, causing climate change around the world.”

This climate is consistent with the current climate and environmental changes seen in other records around the world, such as the mysterious extinction of Australia’s megafaina.

Surprisingly, it also coincides with some of our ancient cave art with records, prompting researchers to speculate that the Adams event could lead humans inside the house.

“This sudden behavioral shift in very different parts of the world is consistent with the increasing or changing use of caves during the Adams event, possibly with the addition of ultra ultraviolet B, to potentially harmful levels, during grandsolar minima or solar energetic particles, which Use can also explain, ”he wrote in his paper.

It is somewhat speculative, of course, but it suggests that geographic currency may be a seriously altered phenomenon. And recent evidence suggests that we are currently on the verge of another.

Researchers say this could be quite devastating in the current environment.

“Our atmosphere is full of carbon at a level never seen by humanity. The opposite or extreme change of the magnetic pole in the activity of the sun would be unprecedented climate change progress,” Terni said.

“We urgently need to take down carbon emissions before such a random event happens again.”
