For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say.

Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth.

New NASA research demonstrates that 540 million years of Earth’s magnetic field changes have corresponded to surface ...

The strength of Earth’s magnetic field and the amount of oxygen in its atmosphere seem to be correlated—and scientists want ...

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say.

The strength of Earth’s magnetic field seems to rise and fall hand-in-hand with the abundance of oxygen in its atmosphere, a study of geological records spanning the last half billion years has ...
