A heavy, colourless gas. Carbon dioxide is given out by animals during respiration and is used by plants during photosynthesis. It is also produced when fuels burn. Carbon dioxide is used in fire extinguishers. Carbon dioxide is a greenhouse gas that contributes to the potential for global warming. The world′s oceans contain the bulk of the world's CO2, 50 times as much as the atmosphere. CO2 absorption by oceans is related to water temperature, with colder water soaking up more CO2 than warm water. Deeper water also holds more CO2 than surface water. In winter, however, colder surface water becomes heavier, forcing the deeper water (the water containing more CO2) to the surface where the CO2 is released into the atmosphere.
