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.

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 ...

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. While it is ...

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 ...

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 ...

Ancient carbon cycle on past Mars Observations of Mars from orbiting satellites and rovers show river channels and dry lakes that suggest the Martian surface once had liquid water.

Rivers transport and release methane and carbon dioxide as part of the global carbon cycle. Until now, scientists believed the majority of this was a quick turnover derived from the recycling of ...

Diatom surprise could rewrite the global carbon cycle Date: July 17, 2024 Source: University of California - San Diego Summary: When it comes to diatoms that live in the ocean, new research ...

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%.

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.
