4. The Greenhouse effect The earth is surrounded by a layer of gases including carbon dioxide. These keep the earth warm by preventing the escape of heat that would normally be lost from the atmosphere The gases act rather like the glass in a greenhouse. They let heat in but prevent most of it from getting out.

5. How do the gases trap heat?

8. Global Warming The world is now warmer than it has been for many thousands of years. Some scientists believe that in the future it will get even hotter. This is called global warming and may cause serious problems on our planet.

17. Effects of Global warming Nobody knows the exact effects some things that may happen could be: Polar ice caps and glaciers would start to melt as temperatures increased Low lying areas would be flooded Some plants and animals would become extinct Heating and energy bills could be reduced
