WebFigure 20.11 Carbon dioxide gas exists in the atmosphere and is dissolved in water. Photosynthesis converts carbon dioxide gas to organic carbon, and respiration cycles the organic carbon back into carbon dioxide gas. Long-term storage of organic carbon occurs when matter from living organisms is buried deep underground and becomes fossilized. WebSulfur hexafluoride (SF 6) is an extremely potent greenhouse gas. SF 6 is very persistent, with an atmospheric lifetime of more than a thousand years. Thus, a relatively small amount of SF 6 can have a significant long-term impact on global climate change. SF 6 is human-made, and the primary user of SF 6 is the electric power industry. Because of its …
