Scientists found that volcanic eruptions triggered short-lived oxygen spikes before Earth's air became breathable.

It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis. Researchers ...

More CO2 leads to more warming ... Ocean ecosystems play a critical role in carbon storage and oxygen generation. Some of these ecosystems are under threat; others remain unexplored.

They also play a vital role in absorbing carbon dioxide and producing oxygen in the ocean. The two most prominent types of plankton in the ocean are zooplankton, which are tiny animal organisms ...
