Carbon dioxide. Computer model of a molecule of carbon dioxide. Atoms are represented as spheres and are colour-coded: carbon (grey) and oxygen (red). Carbon dioxide is a colourless gas at room temperature. It occurs naturally in the atmosphere and has an important role in animal and plant respiration. Carbon dioxide is a greenhouse gas and its increased emission due to human activity contributes to global warming.
