Geochemical evidence suggests that carbon dioxide levels may have been much lower millions of years before the emergence of large forests.

Carbon dioxide may calm bumble bees down, but a new study shows it can also trigger other physiological responses, including in reproduction.

Understanding more about processes that turn carbon dioxide into a solid could lead to its safe burial beneath the Earth's surface.

A new system that uses carbon dioxide to produce bioplastics could cut greenhouse gas emissions and our reliance on nondegradable plastics.

A new, cheap, energy-efficient material could be key to carbon capture. It could even potentially work to suck up carbon from car tailpipes.

New climate change ecology research links the amount of carbon dioxide taken in by land ecosystems, such as forests, to the availability of water.

A textile filter made from cotton and an enzyme that speeds chemical reactions shows promise for removing CO2 from air and gas mixtures.

"This bacterial enzyme is the most efficient carbon fixer that we know of, and we came up with a neat explanation of what it can do."

A new chemical technique "is a great way to have one problem, plastic waste, address another problem, CO2 emissions," says James Tour.
