Carbon dioxide is a greenhouse gas, one of the four main ones. In terms of US greenhouse gas emissions, here's a list by amounts from the Environmental Protection Agency: Carbon dioxide, 79%.

A 2021 study also found the carbon capture process emits significant amounts of methane, a potent greenhouse gas that’s ...

Carbon dioxide is a molecule made of three parts, a central carbon atom tied to two oxygen atoms. It is a gas making up only about 0.04% of our atmosphere, but it is an important component of the ...

From the mud, straw, and gypsum mixtures of ancient Egypt's monumental pyramids to the sophisticated underwater material ...

Levels of carbon dioxide and methane, the two greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their "historically high rates of ...

The ocean absorbs carbon from the atmosphere, but exactly how much is uncertain. For instance, estimates from the 2023 Global ...

But carbon dioxide and other trace gases in the atmosphere do absorb the outgoing long-wave radiation. So while their concentrations are miniscule, their effect is anything but: ...

A case in point: Turning methane (a powerful greenhouse gas) into carbon dioxide (also a planet-warming pollutant) could help fight climate change, researchers say. It’s not that CO2 isn’t a ...

When the air’s carbon dioxide levels rise –- to 400, 600 or 800 ppm – the stomata shrink in size, causing them to lose less water from transpiration, while still absorbing ample CO2 molecules.

Oxy would capture carbon dioxide from the atmosphere, inject it into an oil field, and then argue that the CO2 used to make the oil cancels out the CO2 released by burning that oil.

After methane leaks, it’s over 80 times more potent than carbon dioxide in its ability to warm the planet. That’s why the timing of the Gas Index is important.
