  • Simulations show magnetic field can change 10 times faster than previously thought,” reads the headline from the University of Leeds.

"Here are excerpts from the article:
6 July 2020 – A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth’s magnetic field may take place 10 times faster than previously thought.
...The clearest example of this in their study is a sharp change in the geomagnetic field direction of roughly 2.5 degrees per year 39,000 years ago.
This shift was associated with a locally weak field strength, in a confined spatial region just off the west coast of Central America, and followed the global Laschamp excursion—a short reversal of the Earth’s magnetic field roughly 41,000 years ago...
