atmospheric CO2  

Definition

  • Carbon dioxide (CO2) 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. CO2 absorbs and emits infrared radiation and consequently is a greenhouse gas that plays a significant role in influencing Earth's surface temperature through the greenhouse effect. Between 30% and 40% of the CO2 released by humans into the atmosphere dissolves into the oceans, wherein it forms carbonic acid and effects changes in the oceanic pH balance.
