A new study published in the Russian Journal of Pacific Geology looks into geomagnetic excursions over the last 10 000 years utilizing peat deposits from Russia’s Khabarovsk Territory. The study called into attention the importance of understanding these transitory shifts in Earth’s magnetic poles, which differ from total geomagnetic reversals and impact climatic and environmental circumstances.
A new study published in Nature Communications shows that previous changes in the direction of Earth's magnetic field reached rates that are up to 10 times larger than the fastest currently reported variations of up to one degree per year. The authors combined…
Earth's magnetic field has flipped many times throughout history and is now on its way toward another reversal. While the topic was highly controversial in the 20th century, numerous studies over the past decades have proven this as a fact, that it's…
In this interview, EGU's Laura Roberts Artal speaks with Jay Shah, a Ph.D. student at Imperial College London, who is investigating the South Atlantic Anomaly, a patch over the South Atlantic where the Earth’s magnetic field is weaker than elsewhere on the…
The Earth’s magnetic field surrounds our planet like an invisible force field – protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this field is continuously changing. Indeed, our planet’s…
Research results of the new study indicate the rapid reversals of Earth's magnetic field which occurred about 550 million years ago is responsible for destroying a huge portion of the ozone layer. This destruction has, in turn, allowed a higher concentration of…
It is known that Earth’s magnetic field has flipped many times throughout the planet’s history. Its dipole magnetic field remains about the same intensity for thousands to millions of years, but for incompletely known reasons it occasionally weakens (such is
ESA’s three-satellite "Swarm" constellation was launched into a near-polar orbit by a Russian Rockot launcher on November 22, 2013. In next four years, Swarm satellites will monitor Earth’s magnetic field, from the depth of our
As it does approximately every 11 years on a solar cycle, the Sun's magnetic field is now reversing. Measurements have confirmed that we are about 3 – 4 months away from complete magnetic field reversal when Sun's inner magnetic dynamo will re-organize itself.
