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 ...

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 ...

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 ...

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 ...

Carbon dioxide (CO₂) pollution drives climate change, warming the planet and threatening human survival. Plants naturally turn CO₂ into oxygen (O₂) during photosynthesis, but their efficiency is ...
