-Global Warming
Most people now accept the fact that the world’s climate is changing. But why is this happening and what can we do about it? Scientists believe that there are a number of natural reasons for climate change. One could be changes in how much heat we get from the sun. Another could be volcanoes. When a volcano erupts, it sends dust into the atmosphere. This stops some of the sun’s light and can make our climate cooler. We have also been adding gases like carbon dioxide to the atmosphere. The greenhouse gases stop heat escaping, which increases the earth’s temperature. This is called the greenhouse effect. The carbon dioxide in the atmosphere is increasing mainly because we burn fuels such as oil and gas. The fact that we continue to destroy the rainforests (which take in carbon dioxide and produce oxygen) makes matters worse. If the carbon dioxide in the atmosphere continues to increase,
scientists believe that by 2050, the temperature of the earth’s surface could go up by 2°C.
How will global warming affect the world? It is now known that the ice at the Arctic and the Antarctic is melting. If this continues, sea levels will rise and some parts of the world will be flooded, making many people homeless. So Countries must stop destroying the rainforests and produce less carbon dioxide.
