Carbon dioxide in Earth's atmosphere
Carbon dioxide (CO 2 ) 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. CO 2 absorbs and emits infrared radiation at wavelengths of 4.26 µm (asymmetric stretching vibrational mode ) and 14.99 µm (bending vibrational mode) and consequently is a greenhouse gas that plays a vital role in regulating Earth 's surface temperature through the greenhouse effect .

Carbon dioxide (CO 2 ) is an important trace gas in Earth's atmosphere currently constituting about 0.04%, i.e. 400 parts per million (ppm), of the atmosphere. [1] [2] Despite its relatively small concentration, CO 2 is a potent greenhouse gas and plays a vital role in regulating Earth 's surface temperature through radiative forcing and the greenhouse effect . [3] Reconstructions show that concentrations of CO 2 in the atmosphere have varied, ranging from as high as 7,000 ppm during the Cambrian period about 500 million years ago to as low as 180 ppm during the Quaternary glaciation of the last two million years. |

Carbon dioxide (CO 2 ) is an important long-lived trace gas in Earth's atmosphere currently constituting about 0.04% (400 parts per million) of the atmosphere. Despite its relatively small overall concentration, CO 2 is a potent greenhouse gas and plays a vital role in regulating Earth 's surface temperature through radiative forcing and the greenhouse effect : CO 2 absorbs and emits infrared radiation at wavelengths of 4.26 µm (asymmetric stretching vibrational mode ) and 14.99 µm (bending vibrational mode).

The concentration of carbon dioxide (CO 2 ) in Earth's atmosphere determines its contribution to the greenhouse effect and the rates of plant and algal photosynthesis . The concentration has increased markedly in the 21st century, at a rate of 2.0 ppm/yr during 2000–2009 and faster since then. [1] [2] It was 280 ppm (parts per million) in pre-industrial times, and has risen to 392 ppm in 2013 [3] (with a daily average at Mauna Loa recording 400 ppm as of 10 May 2013 [update] , [4] ) with the increase largely attributed to anthropogenic sources. [5] About 57% of the CO 2 emissions go to increase the atmospheric level, with much of the remainder contributing to ocean acidification . Carbon dioxide is used in photosynthesis (in plants and other photoautotrophs ), and is also a prominent greenhouse gas . Despite its relatively small overall concentration in the atmosphere, CO 2 is an important component of Earth's atmosphere because it absorbs and emits infrared radiation at wavelengths of 4.26 µm (asymmetric stretching vibrational mode ) and 14.99 µm (bending vibrational mode), thereby playing a role in the greenhouse effect . [6] The present level appears to be the highest in the past 800,000 years [7] and likely the highest in the past 20 million years, [8] but well below 10% of its 500-million-year peak. [9] |

The concentration of carbon dioxide (CO 2 ) in Earth's atmosphere has reached 391 ppm (parts per million) as of October 2012 [update] [1] [2] and rose by 2.0 ppm/yr during 2000–2009. [2] [3] This current concentration is substantially higher than the 280 ppm concentration present in pre-industrial times, with the increase largely attributed to anthropogenic sources. [4] Carbon dioxide is used in photosynthesis (in plants and other photoautotrophs ), and is also a prominent greenhouse gas .

[5] The present level is higher than at any time during the last 800 thousand years, [6] and likely higher than in the past 20 million years. [7] |

The concentration of carbon dioxide (CO 2 ) in Earth's atmosphere is approximately 390 ppm (parts per million) by volume as of 2010 [update] . [1] It rises relatively quickly, and even the rise grows quickly. As of 2009 [update] , the rise-rate was 1.6 ppm/yr. [2] Carbon dioxide is essential to photosynthesis in plants and other photoautotrophs , and is also a prominent greenhouse gas . Despite its relatively small overall concentration in the atmosphere, CO 2 is an important component of Earth's atmosphere because it absorbs and emits infrared radiation at wavelengths of 4.26 µm (asymmetric stretching vibrational mode ) and 14.99 µm (bending vibrational mode), thereby playing a role in the greenhouse effect .
