What does CO2 mean? carbon dioxide, CO2, carbonic acid gas (noun) a heavy odorless colorless gas formed during respiration and by the decomposition of organic substances; absorbed from the air by plants in photosynthesisWhat are the reasons for increased CO2?
Burning carbon requires oxygen (O2), and when we burn an atom of carbon, the required oxygen becomes part of the CO2 molecule. So if the CO2 increase is caused by burning carbon (fossil fuels), we would expect atmospheric O2 levels to decrease at the same rate.Is CO2 bad for the environment?
Carbon dioxide is not normally considered a pollutant because it is a normal constituent of air. However, excess of carbon dioxide is considered a [pollutant because it leads to adverse effects on the environment. The higher concentration of carbon dioxide in the atmosphere is likely to increase the temperature of the atmosphere.What are the hazards of CO2?
As the concentration CO2 in air rises it can cause headaches, dizziness, confusion and loss of consciousness. Since CO2 is heavier than air, fatalities from asphyxiation have occurred when, at high concentrations, it has entered confined spaces such as tanks, sumps or cellars and displaced Oxygen.
