carbon dioxide
Definition
- [Henderson's] CO2, a gas present in the atmosphere at a concentration of about 362 ppm. The main sources of atmospheric carbon dioxide are biological respiration, of which it is a waste product, combustion, and outgassing from the oceans. Carbon dioxide is removed from the atmosphere by photosynthesis and by solution in sea-water. Human activity has enhanced the atmospheric concentration of carbon dioxide by the burning of fossil fuels and biomass. It is a major greenhouse gas, trapping heat in the lower atmosphere.
