 Climate is a 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.

But recently the climate has changed a lot, especially in Europe. Scientists think that the reason is greenhouse effect.  It is caused by carbon dioxide (углекислый газ). Carbon dioxide is produced when we burn things. Also people and animals breathe in oxygen and breathe out carbon dioxide. As you know, trees take this gas from air and produce oxygen. But in the last few years people have cut down and burn big areas of rainforest. This means that there are fewer trees and more carbon dioxide.

This gas in the atmosphere works like glass in a greenhouse. It lets heat get in, but it doesn’t let much heat get out. So the atmosphere becomes warmer.

Greenhouse effect is sometimes called global warming.
