Recently climate has changed a lot in our country, especially in its European part. Some scientists think that the world is becoming hotter. Winters have become warmer. Sometimes there is little snow in January and there were winters when it rained on the New Year’s Eve.

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 become much warmer because the heat can’t go back. That’s why winter and summer temperatures in many places have become higher.

During the last 100 years people have produced a lot of carbon dioxide. It lets heat in, it doesn’t let much heat get on. So the atmosphere becomes warmer.

People and animals breathe in oxygen and breathe out carbon dioxide. Trees take this gas and produce oxygen. People have cut down and burn areas of rainforest.

As we see the climate in different parts of the world changes from year to year. This changes are dangerous for our fragile planet. We know many secrets. Yet there is still much to learn.
