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 ...

The Moon has no real atmosphere, but Earth has, in a sense, been generously trying to share its own for billions of years. A new study has found that our planet's magnetic field could be what's ...

Earth’s rotation is gradually slowing down, a process that has been quietly shaping the planet since its formation 4.5 billion years ago. This deceleration, caused by the gravitational pull of the ...

More than a billion years ago, a shallow basin in what is now northern Ontario held a subtropical lake. The setting likely ...

The average level of carbon dioxide in the Earth’s atmosphere had its largest one-year increase on record between 2023 and 2024. In 2024, the level reached 423.9 parts per million, an increase of 3.5 ...

NASA's Atmospheric Waves Experiment (AWE) discovered an unknown phenomenon from the International Space Station, 55 miles ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Growth rates of carbon dioxide have tripled since the 1960s, ...

Over the last decade, humanity's emissions of carbon dioxide (CO₂) have stabilized after a period of huge growth. Average growth is now down to just 0.6% per year, compared to 2% per year in the ...

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. When you purchase ...
