The Earth has warmed by about half a degree (0.5度) over the last 100 years. It could be getting warmer on its own, but many scientists think people are making the Earth warmer by making a greenhouse effect (温室效应). The greenhouse effect is very important, Without it, the Earth would not be warm enough for us to live on. But just a little warmer than it is now could cause problems for humans, plants and animals.

Many of the things we do every day can change the Earth’s temperature. We send greenhouse gases (气体) into the air when we watch TV, turn on lights, dry hair, play video games, wash or dry our clothes or drive cars. The rubbish (waste) from factories and homes also produces (生产) greenhouse gases.

Even a small change in temperature can affect (影响) our weather. This can cause changes in the sea, the air, flooding (洪水) and our fresh water.

The change in the temperature can also cause changes in the living places for animals and plants.

Global warming (全球变暖) is a big problem, and we can do every little bit to help. We can also save many things. Remember: If you do a little, you can bring a better world.
