In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of several greenhouse gases in the atmosphere of Earth. The current global average concentration of carbon dioxide (CO 2) in the atmosphere is 421 ppm (0.04%) as of May 2022. [1]
Atmospheric carbon cycle. Schematic representation of the overall perturbation of the global carbon cycle caused by anthropogenic activities, averaged from 2010 to 2019. [ 1 ] The atmospheric carbon cycle accounts for the exchange of gaseous carbon compounds, primarily carbon dioxide (CO 2 ), between Earth's atmosphere, the oceans, and the ...
Greenhouse gases in the atmosphere are responsible for a majority of the absorption of longwave radiation in the atmosphere. The most important of these gases are water vapor, carbon dioxide, methane, and ozone. [22] The absorption of longwave radiation by gases depends on the specific absorption bands of the gases in the atmosphere. [19]

The five most abundant greenhouse gases in Earth's atmosphere, listed in decreasing order of average global mole fraction, are: [ 5 ][ 6 ] water vapor, carbon dioxide, methane, nitrous oxide, ozone. Other greenhouse gases of concern include chlorofluorocarbons (CFCs and HCFCs ), hydrofluorocarbons (HFCs), perfluorocarbons, SF6, and NF3.
The warming is largely driven by greenhouse gases like carbon dioxide. After being released, carbon dioxide is absorbed by land and the oceans, but some of it remains in the atmosphere and traps ...
Carbon dioxide plays an important role in setting the boundary at the long wavelength end. Ozone partly blocks transmission in the middle of the window. The importance of the infrared atmospheric window in the atmospheric energy balance was discovered by George Simpson in 1928, based on G. Hettner's 1918 [ 7 ] laboratory studies of the gap in ...
The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component of biological compounds as well as a major component of many ...
