In Buhler's model, a 0.4-mile-thick layer of carbon dioxide deposits on top of a 2.5-mile-thick layer of water ice, a layer of water ice about as thick as that which exists on the south pole today.

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 ...

A research team has made significant discoveries regarding the complex reaction mechanisms of carbon dioxide (CO₂) in supercritical water. These findings are crucial for understanding the ...

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 ...

Unveiling hidden reaction kinetics of carbon dioxide in supercritical aqueous solutions. Proceedings of the National Academy of Sciences, 2024; 122 (1) DOI: 10.1073/pnas.2406356121 ...

The atmosphere, by contrast, is about 0.04 percent carbon dioxide, so over one thousand tons of ordinary air would have to be processed in order to capture a single ton of CO2.

DOI: 10.1002/anie.202503003 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?

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%.
