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
Ocean storage of carbon dioxide water column. The carbon dioxide is usually injected at 1000 m depth to reduce carbon dioxide bubble escape. As injected carbon dioxide bubbles rise, dispersal increases up the water column. Large dispersal areas and low concentrations of carbon dioxide significantly decrease any significant changes in local pH and resulting effects on marine ecosystems. Wickett et al. used measurements in natural pH fluctuations from atmospheric carbon dioxide to suggest that dilute carbon dioxide injection at 0.37 GTC/ yr would have a negligible effect on ocean pH. Dilute ocean injection requires little infrastructure in comparison to other forms of ocean injection. The
