ALL MOLECULAR GRAPHICS: CARBON DIOXIDE: CARBON DIOXIDE EMISSION: carbon dioxide molecule, CO2 in atmosphere
At right: Carbon dioxide on white: picture showing a carbon dioxide molecule in the sky with a glow beneath representing the burning of fossil fuels.Image is 500 x 500 pixels; the original image is 4096 x 4096 pixels.
Carbon Dioxide consists of two oxygen atoms covalently joined to a central carbon atom. The three atoms lie in a line (it is a linear molecule). The central carbon atom (black) is pictured as a sphere drawn at the scale of the carbon covalent radius just touching two oxygen atoms (red) drawn at the scale of their covalent radii. The transparent spheres represent the van der Waals surfaces of the carbon and oxygen atoms.
Carbon Dioxide Emissions are considered a major threat to the Earth because of their capacity modify the climate by insulating the surface and so creating a GREENHOUSE EFFECT. The glow at the bottom of the image represents the burning of fossil fuels which is a major cause of increased atmospheric carbon dioxide. There is a major debate about the future sources of energy in Australia as nuclear power is compared with fossil fuels such as coal in an attempt to prevent global warming.
