Anaglyph of a carbon dioxide molecule, CO2

3D stereoscopic anaglyph (view with red-green or red-cyan glasses). Carbon Dioxide, or CO2, is a linear covalent molecule with a central carbon atom and an oxygen atom on either side. Carbon dioxide is a major greenhouse gas. Although not as potent as some other greenhouse gases, it is abundant and is thought to be largely responsible for global warming and climate change.
