Following reports that the Earth’s magnetic poles are on the edge of flipping, a new study was released countering that claim.
A team of international researchers said in a recent study that it is highly unlikely that the Earth’s magnetic field will reverse. It had been predicted that the dreaded event would happen due to the weakening of our planet’s magnetic field for the past two hundred years.
However, the researchers claim that the event won’t happen and the magnetic current of Earth will soon recover.
“There has been speculation that we are about to experience a magnetic polar reversal or excursion. However, by studying the two most recent excursion events, we show that neither bear a resemblance to current changes in the geomagnetic field and therefore it is probably unlikely that such an event is about to happen,” Richard Holme, a professor of Geomagnetism at the University of Liverpool, explained.
“Our research suggests instead that the current weakened field will recover without such an extreme event, and therefore is unlikely to reverse.”
The international team of researchers reportedly used a computer model to make their discovery. The computer was programmed using the data of Earth’s historical magnetism gathered from sediment cores and volcanic rocks around the world.
The scientists then analyzed our planet’s geomagnetic field during the two of the most excursion events known as the Laschamp and Mono Lake. These events happened around 34,000 and 41,000 years ago respectively. During these times, the Earth reportedly came close to reversing but was able to recover its original structure.
The team allegedly found a good record for the time interval of 50,000 to 30,000 years before the present which includes two magnetic dips similar to the South Atlantic Anomaly. The researchers said that the anomalies apparently disappeared.
“Based on our observations of the past 50,000 years we conclude that the South Atlantic Anomaly cannot be interpreted as a sign for the beginning of a reversal of the poles. Times of the past that, unlike the beginning of the Laschamp excursion, showed patterns of the magnetic field like today were not followed by a pole reversal. After some time the anomalies disappeared,” Monika Korte, co-author of the study, said.
