Greenhouse Gases and Their Contribution to Global Warming

What do carbon dioxide, methane, nitrous oxide, fluorocarbons, ozone, and water vapour all have in common? They are all greenhousegreenhouse gases gases. That is, these gases in the atmosphere allow short wavelength solar radiation to pass through and reach the earth, but absorb the long wavelength heat coming back up from the earth and keep it in the atmosphere, thus keeping the earth warm. The diagram shows proportions of several of these greenhouse gases in the atmosphere. An issue of particular concern is release of carbon dioxide into the atmosphere by the burning of fossil fuels.
