Scientists believe that there are a number of reasons for climate change. One reason could be the changes in the amount of heat which actually comes from the sun at different times. Another could be volcanic dust. People have also been adding gases such as carbon dioxide to the atmosphere. These are called greenhouses because they hang in the atmosphere around the earth like the roof and walls of a greenhouse. The earth receives heat and light from the sun that sends this back into space as infrared radiation. Much of this radiation cannot pass through the greenhouse gases and this causes increased temperatures near the earth.

The amount of carbon dioxide in the atmosphere is increasing mainly because all countries burn fossil fuels such as oil, natural gas and coal. The destruction of the big rain forests, which absorb carbon dioxide and give out oxygen, makes matters worse.

What can be done to prevent this situation? Global warming is a problem that affects every country and every person in the world. First of all, all governments must agree to reduce the amount of carbon dioxide that transport and industries emit into the atmosphere. And we can all play a part as individuals. We should all try to reduce the amount of carbon dioxide we emit into the atmosphere. This can be done by driving fuel-efficient cars. The best way people can help is to use public transport as much as possible instead of their cars. And finally, we should plant more trees in the cities and on farms to give us back the air we need. 1. Choose the correct answer a, b or c. a.
