Carbon dioxide is an important greenhouse gas. Burning of carbon-based fuels since the industrial revolution has rapidly increased its concentration in the atmosphere, leading to global warming. It is also a major cause of ocean acidification since it dissolves in water to form carbonic acid.arbon dioxide was the first gas to be described as a discrete substance. In about 1640, the Flemish chemist Jan Baptist van Helmont observed that when he burned charcoal in a closed vessel, the mass of the resulting ash was much less than that of the original charcoal.
Coal is mostly carbon. During complete combustion, carbon is oxidised to carbon dioxide: carbon + oxygen â carbon dioxide. Carbon dioxide is a greenhouse gas greenhouse gases: the gases responsible for the global warming-carbon dioxide, methane, nitrous oxide and CFCs.Increasing concentrations of it in the atmosphere contribute to global warming. Hydrocarbon fuels contain carbon and hydrogen.oal is mostly carbon. During complete combustion, carbon is oxidised to carbon dioxide: carbon + oxygen â carbon dioxide.
