Energy, in the term oi visible light, arrives irom the sun and passes through the atmosphere to the Earth's suriace. The Earth, warmed by the sunlight, gives oii energy not as light but as heat which is radiated back towards the atmosphere. Much oi this heat passes right through the atmosphere and into space to be lost for ever. Some oi the heat, however, is absorbed by the gases in the atmosphere which become warm.

In recent years the composition oi the

atmosphere has changed as a result oi human activity and there is now, amongst a number oi other gases, more carbon dioxide, methane, nitrous oxides and chloroilurocarbons (CFCs). These gases are particularly good at absorbing the heat radiation as it trys to leave the Earth. By doing so they reduce the amount oi heat escaping trom the Earth’s surface, through the atmosphere and into space. The overall result is that the World warms up. The effect on our weather and on sea levels ls uncertain but the predictions are worrying.
