A few years ago, workers who were digging a mine and building a power plant in New Zealand found a 60-ton trunk from a Kauri tree, and now, according to researchers, it captured the last collapse in New Zealand. The earth’s magnetic field.
The huge tree trunk is actually one of the largest tree species in the United States. It is said to be about 42,000 years old and preserved on wet muddy soil-its ring is 1
In this huge piece of wood, the radiocarbon level shows the peak of space radiation Earth’s magnetic field Protect it from becoming weak, the poles actually flipped overAccording to the researchers.
They said that by simulating the effects of this radiation on the Earth’s atmosphere, the Earth’s climate has undergone drastic changes over a period of time, which may be the cause of the extinction of large mammals. Neanderthals from Australia and Europe.
Even more surprising is that the study reports detailed stories about the timing and scale of the two-pole swaps, and is the first to present a credible case (albeit speculative), claiming that this flipping will affect the global climate .
In case you don’t know Earth’s magnetic field The formation of is due to the flow of molten iron in the outer core of the earth’s crust, which is also prone to chaotic swings As we all know, this will not only weaken the magnetic field, but also cause the magnetic poles to move and flip completely.
It is well known that the magnetic orientation of minerals in rocks will leave traces of long-term reversals, but the same cannot be said for reversals that last only a few hundred years (for example, reversals about 42,000 years ago). However, Radiocarbon 14 can detect these brief fluctuations. When cosmic rays from space pass through a magnetic field and hit the atmosphere, they produce isotopes.
This is also absorbed by creatures on earth including trees. The team used radiocarbon to date the above-mentioned kauri wood and obtained accurate but primitive radiocarbon cave records from China. After measuring the subtle changes in carbon 14 in annual rings, they tracked the difference in its growth over 40 years as the magnetic field weakened and surged.
The spikes of radiocarbon indicate that the magnetic field weakened by 6% of its current strength approximately 41,500 years ago. During this period, the pole position flipped and the field recovered a certain amount of strength, but then it crashed and flipped back 500 years later.
The researchers also claimed that at this time, not only the cosmic-ray shielding of our planet is not working, but also our sun. The researchers found from the hints of ice cores that the sun was experiencing an onset of low magnetic activity-known as a minimal minimum-according to them, due to subtropical ionization, they would destroy today’s power grid and be in subtropical regions. Form the aurora. atmosphere.
Running a climate model also shows that this cosmic ray attack will destroy the ozone layer, reduce the heat it originally captured from ultraviolet rays, and also cause changes in high-altitude cooling, changing wind currents and causing catastrophic changes on the earth’s surface. Europe is warming.
