Researchers have created a paint containing living cyanobacteria that produces oxygen and can capture carbon dioxide. The bacteria’s ability to withstand extreme environments means this novel paint ...

Excess carbon dioxide emitted by human activities—such as fossil fuel burning, land-use changes, and deforestation—is known as anthropogenic carbon dioxide. Approximately thirty percent of this ...

A new study of sediment cores shows a series of massive emissions of carbon dioxide over a 20 million year period about 300 million years ago. These CO2 emissions happened at the same time as drops in ...

Methods to enhance the ocean's uptake of carbon dioxide (CO₂) are being explored to help tackle the climate crisis. However, some of these approaches could significantly exacerbate ocean deoxygenation ...

Over 300 million years ago, Earth experienced powerful bursts of carbon dioxide from natural sources—like massive volcanic eruptions—that triggered dramatic drops in ocean oxygen levels. These ancient ...

The solar-powered device can make valuable energy-dense molecules from carbon dioxide and water. For many years, researchers have been working to build devices that can mimic photosynthesis—the ...
