Although individual CO 2 molecules have a short residence time in the atmosphere, it takes an extremely long time for carbon dioxide levels to sink after sudden rises, due to e.g. volcanic eruptions or human activity [17] and among the many long-lasting greenhouse gases, it is the most important because it makes up the largest fraction of the ...
[A] [2] One estimate puts the percentage of Spanish language publications in natural sciences and technology as 0.5% of the world total, [B] a low number since Spanish is often considered to rank second or third among languages in various other metrics and estimates. [4] In the humanities a similar estimate yields 2.81%. [4]
The majority of the fixation occurs in terrestrial environments, especially the tropics. The gross amount of carbon dioxide fixed is much larger since approximately 40% is consumed by respiration following photosynthesis. [6] [7] Historically, it is estimated that approximately 2×10 11 billion tons of carbon has been fixed since the origin of ...
Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products. [98]: 2221 This process is also known as carbon removal, greenhouse gas removal or negative emissions.
Because of the laboriousness of the translation process, since the 1940s efforts have been made, with varying degrees of success, to automate translation or to mechanically aid the human translator. [3] More recently, the rise of the Internet has fostered a world-wide market for translation services and has facilitated "language localisation". [4]
Researchers have demonstrated that the carbon dioxide marine storage at several kilometers depth could be viable for up to 500 years, but is dependent on injection site and conditions. Several studies have shown that although it may fix carbon dioxide effectively, carbon dioxide may be released back to the atmosphere over time.

The Oceanic carbon cycle is a central process to the global carbon cycle and contains both inorganic carbon (carbon not associated with a living thing, such as carbon dioxide) and organic carbon (carbon that is, or has been, incorporated into a living thing). Part of the marine carbon cycle transforms carbon between non-living and living matter.
