Carbon dioxide in Earth's atmosphere Carbon dioxide in Earth's atmosphere Carbon dioxide () is an important trace gas in Earth's atmosphere. It is an integral part of the carbon cycle, a biogeochemical cycle in which carbon is exchanged between the Earth's oceans, soil, rocks and the biosphere. Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis. Almost all other organisms depend on carbohydrate derived from photosynthesis as their primary source of energy and carbon compounds. absorbs and emits infrared radiation at wavelengths of 4.26 µm (asymmetric stretching vibrational mode) and 14.99 µm (bending vibrational mode) and
Carbon sequestration sinks. Carbon sequestration is the process involved in carbon capture and the long-term storage of atmospheric carbon dioxide () and may refer specifically to: Carbon dioxide may be captured as a pure by-product in processes related to petroleum refining or from flue gases from power generation. sequestration includes the storage part of carbon capture and storage, which refers to large-scale, artificial capture and sequestration of industrially produced using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks. Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global
