Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity ...

Drilling a 270,000-year old core from a Tasmanian lake has provided the first Australian record of a major global event where the Earth's magnetic field 'switched '- and the opportunity to establish a ...

Researchers report a global model of the geomagnetic field between 30,000 and 50,000 years ago, according to which the field structure during the two most recent geomagnetic excursions--large ...

News of the approaching magnetic pole reversal might have been greatly exaggerated. At least this is the opinion of an international team of researchers, who compared the current state of our planet’s ...

There has been speculation that the Earth’s geomagnetic fields may be about to reverse, with substantial implications, due to a weakening of the magnetic field over at least the last two hundred years ...

Geomagnetic polarity reversals and excursions in the Quaternary correlate well with interglacial-to-glacial transitions and glacial maxima. It is suggested that this relationship results from ...
