The strength of the geomagnetic field at Earth's surface three times during the past: 48,500 and 47,250 thousand years ago and in 2015. The geomagnetic field of the past showed areas of weak intensity ...

The geomagnetic field, generated by the convecting motions of Earth’s liquid outer core, is a fundamental facet of our planet’s evolution. Its long‐term behaviour is recorded in rocks through the ...

The findings of a new study by the University of Liverpool provides further evidence of an approximately 200-million-year long cycle in the strength of the Earth’s magnetic field. Researchers ...

Earth's magnetic field and oxygen levels are inextricably linked, new research suggests. The strength of the geomagnetic field has gone up in lockstep with the percentage of oxygen in Earth's ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. The findings of a new study by the University of Liverpool ...

Geomagnetic storms are capable of sparking beautiful displays of the Northern Lights across our night sky. However, there is a potential danger behind that beauty, especially now, with solar activity ...

As with any such correlation, one has to entertain the notion that said correlation might be spurious or indirectly related before assuming a strong causal link. Here it is for example known already ...

The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal.

The findings of a new study by the University of Liverpool provides further evidence of an approximately 200-million-year long cycle in the strength of the Earth’s magnetic field. Researchers ...
