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.
Carbon dioxide is one of several greenhouse gases that help in this. Carbon dioxide captures some of this radiated heat and keeps it in the atmosphere. Some other greenhouse gases are water vapor, methane, nitrous oxide, and CFCs. In fact, any gas with three or more atoms acts as a greenhouse gas.arbon dioxide is the most commonly cited greenhouse gas because of  its natural abundance in the atmosphere. It constitutes 80% of the  non-condensing greenhouse gases. Exp â¦ erts believe that the removal  of CO2 will cool the Earth by 30 degrees Celsius.
