WHATS THE OZONE LAYER GOT TO DO WITH GLOBAL WARMING ?

The ozone layer is another important part of the atmosphere.

It's made up of ozone (a type of oxygen) that protects the earth from too many harmful rays called UVB.

SO WHAT COULD HAPPEN ?

If Earth gets hotter, some of the important changes could happen:

• Water expands when it's heated and oceans absorb more heat than land, so sea levels would rise.
• Sea levels would also rise due to the melting of the glaciers and sea ice.
• Cities on coasts would flood.
• Places that usually get lots of rain and snowfall might get hotter and drier.
• Lakes and rivers could dry up.
• There would be more droughts making hard to grow crops.
• Less water would be available for drinking, showers and swimming pools.
• Some plants and animals might become extinct because of the heat.
• Hurricanes, tornadoes and other storms which are caused by changes in heat and water evaporation may get more common.

SO WHATS BEING DONE ABOUT IT?

The United Nations has meetings where world leaders agree on what to do about global warming. Every five years, the Earth Summit happens In 1997 there was an Earth Summit in Rio de Janeiro and in 1997, an agreement was made at the UN Conference on Climate Change in Kyoto, Japan, to cut the amount of gases that industries make. Leaders agree the world can cut the amount of carbon dioxide that's released into the atmosphere by changing the way power is produced too. In February 2003, the British Government set out its plans to produce electricity using "greener" ways.
