Human activitiesover the past two centuries have increased the amount of carbon in the atmosphere by nearly 50% as of the year 2020, mainly in the form of carbon dioxide, both by modifying ecosystems' ability to extract carbon dioxide from the atmosphere and by emitting it directly, e.g., ...
These carbonate rocks are recycled at plate boundaries and decarbonation reactions return carbon dioxide back to the atmosphere. These processes are often written in the short hand form called the carbonate silicate cycle: (13)CO2+CaSiO3⇔CaCO3+SiO2. Reaction (13) going to the right expresses ...

Microorganisms that use carbon dioxide (the most oxidized form of carbon) as their major or even sole source of carbon are called autotrophs. They can live exclusively on relatively simple inorganic molecules and ions absorbed from the aqueous and gaseous environment. View chapterExplore book ...
On Mars, dendritic patterns are emblematic of exotic geomorphological processes. These processes are driven by a cycle which does not occur on Earth; namely the seasonal phase change of carbon dioxide between solid and gas. The Martian atmosphere comprises over 95%[Math Processing Error]CO25, at...
Efficient and sustainable methods for carbon dioxide capture are highly sought after. Mature technologies involve chemical reactions that absorb CO2, but they have many drawbacks. Energy-efficient alternatives may be realised by porous physisorbents with
and between short-term and longer-term considerations, and coordinated efforts in terms of maintaining steady growth and restructuring. Endeavors to peak carbon dioxide emissions and achieve carbon neutrality must be incorporated into th...
“Consolidation and strengthen of carbon sink capacity”, as one of ten key tasks, has been listed in an action plan for peaking carbon dioxide emissions by 2030 in China, to consolidate carbon sequestration of ecosystem (including karst) and strengthen fundamental support of carbon sink. In kars...
