Storage of water in artificial reservoirs shifted Earth’s rotational poles by 113 cm (44 inches) and caused a 21 mm (0.83 inches) global sea level drop between 1835 and 2011, according to new research published in Geophysical Research Letters on 23 May, 2025.
Around 41 000 years ago, Earth’s magnetic field weakened by up to 90 percent during a geomagnetic excursion known as the Laschamps event. This rare event reduced the planet’s natural shielding against solar and cosmic radiation, exposing the surface to increased ultraviolet energy. A new study combining space weather modeling and archaeological evidence shows that early humans adapted to these extreme conditions through the use of ochre, clothing, and caves, while Neanderthals may have lacked such protective strategies, which may have contributed to their extinction.
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.
In a groundbreaking study published on February 3, 2024, a team of scientists led by Daniil Tolmachev introduced a novel approach to predicting Earth’s magnetic field reversals. Titled “Predictability of Magnetic Field Reversals,” the research utilizes mathematical modeling to identify early warning signals of these geomagnetic phenomena, potentially offering a new paradigm in understanding and preparing for their consequences on technology and life on Earth.
Around 42 000 years ago, a major weakening of Earth’s magnetic field occurred, an event that may have contributed to abrupt climate changes, ecological shifts, and changes in early human behavior, according to a new study.
A team of researchers from Japan made the most detailed and complete record to date of Earth's last magnetic reversal that took place about 773 000 years ago. Their results were published recently in the Progress in Earth and Planetary Science, a Springer…
In a new study, scientists from the University of Liverpool in England traced back the strange behavior of the magnetic field in the South Atlantic region and found that similar anomalies existed as far back as 8 to 11 million years ago. The South Atlantic Anomaly…
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…
For several years now, scientists have been puzzled as to why the Earth's north magnetic pole has been moving rapidly from the Canadian Arctic towards Siberia. After studying 20 years of satellite data, researchers from the University of Leeds in the UK and the…
Over the past 200 years, Earth's magnetic field has lost around 9% of its strength. Meanwhile, a large region of reduced magnetic intensity has developed between Africa and South America — known as South Atlantic Anomaly. Over the past 5 years, however, a…
