carbon dioxide
carbon dioxide A colourless odourless gas, CO
2, which dissolves in water to give
carbonic acid. It occurs in the atmosphere (0.04% by volume) but has a short residence time in this phase as it is both consumed by plants during
photosynthesis and produced by
respiration and by combustion.
The level of carbon dioxide in the atmosphere has increased by some 12% in the last 100 years, mainly because of extensive burning of fossil fuels and the destruction of large areas of
rainforest. This has been postulated as the main cause of the average increase of 0.5°C in global temperatures over the same period, through the
greenhouse effect. Atmospheric CO
2 concentration continues to rise, in spite of some tentative steps to control emissions, giving the prospect of accelerated global warming in the foreseeable future.
