[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]
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 ...
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.
Carbon dioxide forms carbonic acid when dissolved in water, so ocean acidification is a significant consequence of elevated carbon dioxide levels, and limits the rate at which it can be absorbed into the ocean (the solubility pump).
This time, under UN rules, the US has to wait a year until it is officially out. The US is the only nation to have withdrawn from the Paris deal, and joins Iran, Libya and Yemen as the countries ...
In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide. However, this is less than one percent of the carbon dioxide put into the atmosphere by burning fossil fuels. [2] [32] [37]
