The university report described the result as a "carbon-negative building material," meaning the team's mineral output removed more carbon dioxide from the atmosphere than the process emitted.

When we think about trees, we often imagine them growing from the soil, but did you know that less than 10% of a tree's weight comes from the soil? The rest of the tree’s bulk comes from somewhere ...

The ocean serves as Earth's largest dynamic carbon sink, absorbing 400 million tons of carbon dioxide (CO₂) annually through ...

A new theory suggests that liquid carbon dioxide rivers, not water, could have helped shape the surface of Mars.

Students explore whether carbon dioxide from other sources, namely carbonated water and a chemical reaction between baking soda and vinegar, can also make a solution acidic. Students then observe a ...

Even so, carbon capture is an important tool to reduce carbon dioxide emissions, particularly in heavy industries, said Sangeet Nepal, a technology specialist at the Carbon Capture Coalition.

Usually, Buhler spends his time modeling the carbon-dioxide cycle on Mars today. During Martian winter, a layer of carbon-dioxide ice settles out on top of the polar caps of water ice.

A new model accounting for the role of bubbles in air-sea gas exchanges suggests that ocean carbon uptake is more variable ...

Insulation provided by carbon dioxide ice above the martian polar caps could explain many of the Red Planet’s ancient river features.

What if a machine could suck up carbon dioxide from the atmosphere, run it through a series of chemical reactions, and essentially spit out industrially useful plastic?

Rocks remove more carbon dioxide from the atmosphere when it’s warm and rainy, in a process that's like nature's air filter.
