In an attempt to prepare for shift in earth’s polarity – as this would deeply affect many modern electronics and procedures – has led scientists to study stalagmites in the Sanxing Cave in southern China. Previous theories stated that a polarity shift would take hundreds, maybe even thousands of years, but important data collected from the stalagmites show that it could happen much faster – in just 150 years, as it once happened 98,000 years ago.
Key Takeaways:
- Although it has only been recorded as an event once in modern man’s history, prior study suggests the Earth had experienced reversals in magnetic polarity before.
- Were such a reversal to happen today, it would be very problematic for the many technological devices now in use.
- Scientists hope to discover clues that will enable the possibility of predicting and potentially preventing, or at minimum at least preparing for, the next magnetic reversal.
“A large team of researchers from China, Taiwan and Australia has found evidence of faster-than-expected shifts in Earth’s magnetic polarity several thousand years ago.”
