The paper, led by Planetary Science Institute Research Scientist Peter Buhler, describes how 3.6 billion years ago, carbon dioxide froze out of Mars' atmosphere and deposited on top of a water ice ...

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.

The model shows that in this ancient setting, warming the equatorial regions causes carbon dioxide to condense into a sheet 0.4 mile (0.6 km) thick at the poles, on top of a water-ice cap 2.5 ...

Aker's technology uses water and solvents to absorb carbon dioxide in a process that can be applied to emissions from gas, coal, cement manufacturing and oil refining.

In the current climate, for average all-sky conditions, water vapour is estimated to account for 50% of the total greenhouse effect, carbon dioxide 19%, ozone 4% and other gases 3%. Clouds make up ...

Direct Air Capture. To a layman, the words “carbon capture” might suggest something like a giant air filter. A technology like that does exist, and the Infrastructure Investment and Jobs Act ...

Levels of heat-trapping carbon dioxide in Earth’s atmosphere increased to record highs in its spring peak, yet another sign that global warming isn't slowing down. News Home Page ...

But previous systems have added ethylene that comes from petroleum products, rather than deriving it from carbon dioxide and water. The conversion of CO 2 all the way to plastic has been ...

Water could play a crucial role in reducing global carbon dioxide (CO 2) emissions, according to Johns Hopkins engineers.. A team led by A. Shoji Hall, an assistant professor of materials science and ...

Peatlands, formed by ancient wetlands, store more carbon than the world's forests. But when they're drained for farming, they vent heat-trapping carbon dioxide into the air.

Huge shells of frozen carbon dioxide at Mars' south polar cap resulted in subsurface meltwater, which fed a huge system of rivers, lakes and even a sea, a new study suggests.
