SOMEWHERE ON THIS SITE, GUS POSTED ABOUT THE MAGNETIC FLIP...

UNDER A SERIOUS GEOPALEONTOLOGIST'S TUTELAGE, GUS STUDIED THIS "IRREGULAR" EVENT OF PLANET EARTH WHICH HAPPENS EVERY SO OFTEN IN 100 THOUSANDS OF YEARS... WE KNOW...

THE LAST FLIP [NORTH MAGNETIC POLE INVERTING INTO THE SOUTH MAGNETIC POLE] HAPPENED RECENTLY,  ABOUT 42,000 YEARS AGO. THE SEA BEDS "RECORD" THE FLIPS AT THE EXPANDING JUNCTURE OF TECTONIC SEA PLATES [WHICH EVENTUALLY SINK UNDER CONTINENTAL PLATES OVER MILLION OF YEARS]. EVERY TIME A FLIP HAPPENS, THE IRON LADDEN OOZE SURGING BETWEEN THE SEA PLATES CHANGES POLARITY. THIS HAS BEEN MEASURED WITH HIGH DEGREE OF PRECISION.

THE FLIP DOES NOT HAPPEN FROM ONE DAY TO THE NEXT, BUT OVER 300 TO 500 YEARS.

FIRST THE STRENGTH OF THE MAGNETOSPHERE THAT PROTECTS THE EARTH FROM SOLAR "WINDS" OF CHARGE PARTICLES WEAKENS. THIS LEADS TO EXTREME INCREASES IN UV RAYS AND LIFE THREATENING PARTICLES REACHING THE SURFACE OF THE EARTH.

ACCORDING TO SOME ANALYSTS THIS WAS PART OF THE DEATH KNELL FOR [NAKED] NEANDERTHALS AND MEGAFAUNA. MODERN HUMANS SURVIVED BY HIDING IN CAVES. THIS IS CONTROVERSIAL...

In 1987, an electron spin resonance test conducted on bone fragments from LM3's skeleton established an estimate of his age at 31,000 years, plus or minus 7,000 years. In 1999 Thermoluminescence dating work was carried out on quartz from unburnt sediment associated with the LM3 burial site with the selective bleach results indicating a burial older than 24,600 ± 2,400 and younger than 43,300 ± 3,800 years ago.[18] Later Thorne et al. (1999), arrived at a new estimate of 62,000 ± 6,000 years. This estimate was determined by combining data from uranium-thorium dating, electron spin resonance dating and optically stimulated luminescence (OSL) dating of the remains and the immediately surrounding soil.[19]

However, this estimate was very controversial.[20][21][22] The lowest level of the LM3 which are as old as 43,000 years demonstrated that LM3 should not be older than the lowest layer. However, the ANU team had dated the stratum itself to be between 59,000 and 63,000 years old. The problems with using uranium-thorium dating on tooth enamel were criticised. The results from 25 additional OSL tests suggest that LM3 can not be older than 50,000 years BP. According to anthropologist Peter Brown, with the absence of the original deposit that once lay above the burial, a minimum age for the burial has not been established, only a possible maximum.[13]

In 2003, Professor Bowler led a project bringing together a multi-disciplinary team of Australian expert groups (comprising four Australian universities, the NSW National Parks & Wildlife Service and the CSIRO, as well as including descendants of the Mungo people) to collaborate on a final determination of the skeleton's age. They reached a consensus that LM3 is about 40,000 years old....

CAN WE ASSOCIATE THIS DATING WITH THE LASCHAMPS EVENT 42,000 years ago?

 

=====================

 

The Laschamp or Laschamps event,[a] also termed the Adams event,[2] was a geomagnetic excursion (a short reversal of the Earth's magnetic field) that occurred between 42,200 and 41,500 years ago, during the Last Glacial Period. It was discovered from geomagnetic anomalies found in the Laschamps and Olby lava flows near Clermont-Ferrand, France in the 1960s.[3][4]

The Laschamp event was the first known geomagnetic excursion and remains the most thoroughly studied among the known geomagnetic excursions.[5]

It is named after the village of Laschamps, part of the commune of Saint-Genès-Champanelle in France.

Background and effects

Since its discovery, the magnetic excursion has been demonstrated in geological archives from many parts of the world.[5] The transition from the normal field to the reversed field lasted approximately 250 years, while the magnetic field remained reversed for approximately 440 years. During the transition, Earth's magnetic field declined to a minimum of 5% of its current strength, and was at about 25% of its current strength when fully reversed. This reduction in geomagnetic field strength resulted in more cosmic rays reaching the Earth, causing greater production of the cosmogenic isotopes beryllium-10 and carbon-14, a decrease in atmospheric ozone, and changes in atmospheric circulation.[6][7]

This loss of the geomagnetic shield has been claimed to have contributed to the extinction of Australian megafauna, the extinction of the Neanderthals and the appearance of cave art.[8][9][10] However, the lack of corroborating evidence of a causal link between the Laschamp event and population bottlenecks of many megafauna species, and the relatively moderate radio-isotopic changes during the event, have cast significant doubt on the real impact of the Laschamp event on global environmental changes.[11]

Because it occurred approximately 42,000 years ago, the period has been termed the Adams Event or Adams Transitional Geomagnetic Event, a tribute to science fiction writer Douglas Adams, who wrote in The Hitchhiker's Guide to the Galaxy that "42" was the answer to life, the universe and everything.[12][13]

Research

The Australian Research Council funded research to analyze a fossilized kauri tree found in New Zealand in 2019. Radiocarbon dating revealed that the tree was alive from 42,500–41,000 years ago, within the timeframe of the event.[14][15]

====================

 

Scientists discovered magnetic reversals by measuring the magnetic field on either side of Mid-Atlantic Ridges from which molten rock is extruded like toothpaste from a tube. As it solidifies, its crystals align along the direction of Earth’s magnetic field at the time, leaving a ‘tape recording’ of reversals.

Reversals are believed to take place over 1,000 to 10,000 years [GUS: ACCORDING TO SERIOUS SOURCES, REVERSALS ARE BETWEEN 100,000 AND 400,000 YEARS APART], during which time the field shrinks to zero before growing again with the opposite polarity. There were therefore times – maybe even centuries – when Earth had essentially no magnetic field.

This is dangerous for life since the planet’s magnetic field extends far into space and creates a protective bubble around Earth, shielding the planet’s surface from the hurricane of particles of the Sun’s solar wind and higher-energy cosmic ray particles from deep space.

=======================

 

How often do reversals occur?

As a matter of geological record, the Earth's magnetic field has undergone numerous reversals of polarity. We can see this in the magnetic patterns found in volcanic rocks, especially those recovered from the ocean floors. In the last 10 million years, there have been, on average, 4 or 5 reversals per million years. At other times in Earth's history, for example during the Cretaceous era, there have been much longer periods when no reversals occurred. Reversals are not predictable and are certainly not periodic in nature. Hence we can only speak about the average reversal interval.

DO WE NEED TO KNOW ALL THIS AT A TIME WHEN HUMANS ARE ABOUT TO CARELESSLY DESTROY THE SURFACE OF THIS LITTLE PLANET? DO WE NEED ALIENS AND AI TO INSERT SOME SENSE INTO OUR MORONIC LEADERS'S BRAINS, LIKE SUPPOSITORIES....?
