WEATHER AND CLIMATE

Climate is the weather a certain place has over a long period of time. Climate has a very important influence on plants, animals and humans and is different in different parts of the world. Recently climate has changed a lot. Winters have become warmer in our country and there is little snow in January. Many people say that it is so because of the greenhouse effect. It works like this: sunlight gives us heat. Some of the heat warms the atmosphere, and some of the heat goes back into space. Nowadays the air surrounding the earth has become much warmer because the heat can’t go back into space. During the last 100 years people have produced a lot of carbon dioxide. People and animals breathe in oxygen and breathe out carbon dioxide. We produce carbon dioxide when we burn things. This gas in the atmosphere works like glass in the greenhouse. It lets heat get in, but it doesn’t let much heat get out. So the atmosphere becomes warmer. As we see the climate in different parts of the world changes a little from year to year. These changes can be dangerous for our fragile planet which needs protection.
