This site provides an overview of climate change and how it may impact the world over the coming century. Topics include a description of climate change and the greenhouse effect, potential consequences, and ways to adapt to changes to the climate (e.g., use of renewable energy sources). There is also a discussion of some international policy initiatives (Kyoto Treaty, Bonn conference, Johannesburg Summit)) to alleviate global warming. Other materials include a message board, a collection of audio interviews, and an interactive game ("I'm Alright Jack") in which players make decisions about lifestyle and observe how their decisions affect the environment.
