The greenhouse effect is a natural phenomenon that warms the earth and enables it to support life. Without it, the average temperature on earth would be around -18 degrees C, instead of the current +15 degrees C - a frozen wilderness. It works on the same principles as the ordinary glass garden greenhouse, where glass allows light to get in, ...

... radiation. Infrared rays have a longer wavelength than visible light, and for this reason can be absorbed by certain gases in the atmosphere, labelled greenhouse gases. This absorption of heat warms up the atmosphere, which in turn radiates some of the heat back to the earth. Greenhouse gases include water vapour, carbon dioxide (CO2), methane (CH4), chloroflurocarbons (CFCs), Ozone (O3), and Nitrous Oxide (N2O). It all seems very straightforward: greenhouse gases trap the sun's heat, warming ...
