Researchers say that the Earth's oxygen levels will drop exponentially in the future, ending life as we know it.

In an era dominated by concerns over climate change and rising sea levels, a more fundamental, often overlooked threat is ...

Theoretically, “without any involvement of life at all, simply through whole-planet-scale geochemical cycling and tectonics, one could give rise to higher oxygen in the atmosphere of our planet ...

Breathe easy, for now. Scientists say our breathable air won't last forever. A new NASA-supported study warns that Earth's oxygen supply is not a permanent feature of our planet. Though we often take ...

With its low density and unusually cool, methane-rich atmosphere, this planet offers a rare window into giant planet ...

MOXIE extracts carbon dioxide from the atmosphere and turns it into oxygen and carbon monoxide, but in order to make that happen at a meaningful scale, a similar device would need to consume a ...

They found that large-scale volcanic activity increased atmospheric ... which in turn temporarily increased atmospheric oxygen. The increase in oxygen was not very steady, though, and came and ...

The thin Martian atmosphere is 96% carbon dioxide, which isn’t much help to oxygen-breathing humans ... This would suggest that a full-scale system, designed to run continuously, could do ...

"With this model, we offer the most complete possible understanding of this cycle on a large scale ... consuming more oxygen than they produce, making them a growing sink of atmospheric oxygen.

which produces oxygen from the Martian carbon dioxide atmosphere. The 10-person team at Noon Energy has since developed a battery that stores energy in carbon and oxygen using “nature-based ...
