It carries us on a 583-million-mile cruise around the Sun every year. It even has its own "force field." Earth has a magnetic field that protects us from killer radiation and brutal solar wind. For its life-support system, Earth has all the air, water, and food we need.

Just like astronauts on a long space voyage, we need to monitor all our "ship's" vital functions and keep our Earth "ship shape."
Earth has its own control system. The oceans, the land, the air, the plants and animals, and the energy from the Sun all affect each other to make everything work in harmony. Nothing changes in one place without changing something in another place. The overall effect gives us our global climate.
But how do they know that? What are we doing that could cause the whole planet to get warmer? And how could warming happen so fast? What will happen to people and other living things if the planet keeps getting warmer? And what can we do to slow down or stop the warming?
