Describes the factors involved in climate change, that the world is warming up, that farming and deforestation play a role in the process, and that it could change ecosystems.

Explains what climate change is and why it occurs, examines the problems caused by climate change, discusses what might happen if the climate change problem is not fixed, and looks at what is being done to fight climate change.

From sucking carbon straight out of the air to physically blocking out sunlight, the options may seem far-fetched. Can geoengineering really work? How much would it cost? And what are the risks of engineering Earth's climate?
