Did an Ancient Magnetic Field Reversal Cause Chaos for Life on Earth 42,000 Years Ago?

Humans today take Earth’s magnetic North Pole for granted. But over the course of the planet’s history, the direction of its magnetic field has shifted. A new study suggests that the last time the field flipped around and flopped back again, the effects on Earth’s surface were cataclysmic, Carolyn Gramling reports for Science News The study, published on February 19 in the journal Science Laschamps excursion . By comparing the chemicals preserved in the tree rings to atmospheric records found in ice cores and soil, the researchers drew conclusions about the magnetic field’s effect on the ozone layer, as well as solar activity and space weather.
Many effects and side effects include:
They link the environmental effects to the extinction of large animals in Australia, the eventual demise of Neanderthals and humans’ use of red ocher pigment for cave art and sunscreen.

Wow, things we just don't want to think about. They are just too hig for our tiny points of view
ReplyDeleteYes dear "Unknown", but it's the same for all people at all times. When Vesuvius went off with a bang in 79AD the people of that region didn't know that it had already gone off 1700 years before it annihilated Pompeii because they had no records of the previous time.
ReplyDeleteLove that it’s called the Adams Era
