The collapse of the Earth’s magnetic field 42,000 years ago caused sudden climate change

Researchers from the University of New South Wales in Sydney released a study looking at the last major geomagnetic reversal that occurred on Earth about 42,000 years ago. The team says that Earth’s magnetic field collapsed at that time and caused a sudden massive climate change on the planet. Around the world, there have been a few centuries of what the team calls the apocalyptic conditions caused by the reflection of Earth’s magnetic poles along with the behavior of the sun.

The Geomagnetic reflection It brought about a series of dramatic events that had a major impact on the planet. During the reflection, the ozone layer was destroyed, electrical storms devastated the tropics, solar winds generated auroras all over the planet, and Arctic air swallowed North America as freezing air flowed into North America, ice sheets and glaciers formed rapidly with changing weather patterns dramatically .

All life on Earth at that time faced severe trials and tribulations. Researchers believe this event could be what led to the extinction of Neanderthals and other megafauna and forced modern humans to seek protection in caves. Scientists suggest that the magnetic north pole where the compass needle points has no permanent location.

It usually oscillates near the geographic north pole, which is the point around which the Earth rotates due to the movements of the Earth’s core. Scientists don’t understand exactly what could cause the magnetic pole’s more extreme movements than the oscillation, but they have been known to happen. An event that occurred about 42,000 years ago is known as the La Champagne Voyage.

Scientists have used data gathered from inside New Zealand’s ancient tree rings preserved in peat swamps and other sediments for more than 40,000 years. The information preserved in the rings shows how the planet’s atmosphere changed during this time.
