Earth's Magnetic Field and Atmospheric Oxygen: A 500 Million Year Correlation
2025-06-20
A new NASA study reveals a remarkable 500-million-year correlation between the strength of Earth's magnetic field and atmospheric oxygen levels. The research suggests that deep Earth processes may influence surface habitability. By analyzing paleomagnetic records and ancient oxygen levels, scientists found striking similarities in their fluctuation patterns, hinting at a common underlying process, such as continental movement. This discovery offers a new perspective on the link between life's evolution and Earth's internal processes, though the precise mechanisms require further investigation.
