Read and find out about the greenhouse effect and what you can do to help fight global warming in this colorfully illustrated nonfiction picture book. The temperature on Earth is rising. At the North Pole, ice is melting. In the ocean, water is getting higher. And in some places around the world, whole rivers might even dry up. But why is this happening, and what can we do to stop it?
In the Arctic, the summer ice is melting, making it hard for polar bears to survive. Why is the world getting warmer? The heat of the sun is trapped by the "greenhouse" gases that surround Earth--carbon dioxide, methane, nitrous oxide, and water vapor.
Earth gets most of its heat from the sun. The sun's energy travels through space and enters Earth's atmosphere. Some of this energy is reflected back into space by the atmosphere and clouds, and some of it is absorbed and stored as heat by Earth's surface. When the surface and atmosphere become warm, they radiate heat back into space. This helps keep Earth from becoming too hot or too cold.
