Turbulence and extinction are related to the magnetic reversal of the Earth 42,000 years ago



During the Adams event, the magnetic field strength of the earth only dropped to 0% to 6%. We basically have no magnetic field. Our cosmic radiation shield has completely disappeared.

These scientists say that the sky will be illuminated by widespread aurora due to the extinction of the earth caused by a magnetic reversal 42,000 years ago. These scientists believe that this reversal may help explain the mysteries of evolution, such as the extinction of Neanderthals. Picture from Unsplash/UNSW.

The results are amazing. Solar flares and cosmic rays from the Milky Way deprive the Earth’s atmosphere of particles, ionize the air and destroy the ozone layer. Our ancestors will witness the shocking light show in the sky day and night. The aurora, which is usually restricted to polar regions, spreads around the world. Ionized air was originally an important conductor of thunderstorms, thereby increasing the frequency of thunderstorms.

The turbulence above the head-and the loss of UV protection from the ozone layer-can explain the sudden emergence of cave art when early humans retreated to caves for protection.

As science The magazine reported on February 18:

…The world is turned upside down-at least magnetically.

Trees are the key to mystery

The kauri tree is the largest tree species in New Zealand and is the key to understanding this ancient environmental crisis. The kauri tree is sometimes called the god of the forest and is some of the oldest forests in the world. A few years ago, a worker found a 60-ton kauri tree trunk while breaking ground on a power plant in New Zealand. This tree that was originally preserved in the swamp is 42,000 years old and is a precious time capsule for scientists. Its ring spans approximately 1,700 years and captures the magnetic reversal.

This short-lived magnetic reversal was previously known, but previously, its impact on the earth was thought to be slight. The event was discovered in the Laschamps lava flow in Clermont-Ferrand, France in the 1960s, which is evident in the study of the magnetism of ancient lava. This magnetic reversal is short-lived. This is what scientists call an offset: it is not a permanent change in the earth's magnetic field, but a temporary change. As you know, the magnetic north and south poles of the earth are not fixed, nor are they related to the rotation axis of the earth. The magnetic poles fluctuate, sometimes completely swapping positions, which seems to have happened temporarily between 41,000 and 42,000 years ago. This special temporary switch lasted about 800 years before restoration. It is now called Laschamps Event or Laschamp Tour.

As Turney explained:

For the first time in history, we were able to accurately determine the timing and environmental impact of the last magnetic pole switch. These discoveries are made possible by ancient New Zealand kauri trees, which have been preserved in sediments for more than 40,000 years. Using ancient trees, we can measure and determine the peak level of radiocarbon in the atmosphere caused by the collapse of the Earth's magnetic field.

Therefore, the Rachan event refers to the magnetic pole reversal itself. The new term used by scientists in 2021 – Adams Incident – More broadly refers to the impact on the earth during that time. The Earth seems to have seen aurora, electric storms and an increase in cosmic radiation, leading to an increase in the level of radiocarbon in the atmosphere. Researchers link these events to the extinction of large animals in mainland Australia and Tasmania 42,000 years ago.

Scientists have conducted many studies on the malfunction during the Laschamp incident. This new research focuses on the time period before the Laschamp event, as the magnetic field migrates to opposite locations across the planet. Scientists have discovered that this period is the most turbulent period on the earth.

By studying kauri trees, researchers were able to create a more detailed timeline of Laschamp events. As Alan Cooper of the South Australian Museum further explained:

Kauri trees are like Rosetta steles, helping us to connect records of environmental changes in caves, ice cores and peat swamps around the world.

Will it happen today?

Some evidence suggests that changes in the direction of the earth's magnetic field are already in progress. Scientists have discovered that the magnetic poles of the North Pole have drifted faster in recent years than in the past. In the past 170 years, the Earth’s magnetic field has weakened by approximately 9%.

If the incoming radiation destroys our power and communication resources, the modern society’s dependence on power grids and satellites will give rise to dystopian novels. Turney said that the climate change issue adds additional factors to the disaster:

Our atmosphere is full of carbon that humans have never seen before. Magnetic pole reversal or extreme changes in solar activity will be unprecedented climate change promoters. Before such random events happen again, we urgently need to reduce carbon emissions.

Bottom line: The radiocarbon dating in kauri trees helped researchers link the magnetic field reversal 42,000 years ago to environmental disasters and extinction events.
