To mitigate global climate change, emissions of the primary culprit, carbon dioxide, must be drastically reduced. A newly developed process helps solve this problem: CO 2 is directly split ...

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 ...

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 ...

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 ...

A 3D plastic model of a carbon dioxide molecule. Strategies for using carbon dioxide in synthesis usually focus on the carbon atom. Now researchers are thinking about how to put its two oxygens to use ...

There is widespread recognition that efforts to meet global climate targets cannot be met by curbing new carbon dioxide emissions alone and will also require removing carbon from the atmosphere at ...
