A short video on how changing climate is impacting the ecosystem and thereby impacting traditional lifestyles of the Athabaskan people of Alaska.

This static graph of changes in CO2 concentrations goes back 400,000 years, showing the dramatic spike in recent years.

This music video features a rap song about some of the causes and effects of climate change with the goal of increasing awareness of climate change and how it will impact nature and humans. The website also includes links to short fact sheets with lyrics to the song that are annotated with the sources of the information in the lyrics.

A set of eight photographs compiled into a series of slides explain how urban areas are facing challenges in keeping both their infrastructure and their residents cool as global temperatures rise. Chicago is tackling that problem with a green design makeover. This report is part of PBS's Coping with Climate Change series and could challenge students to consider engineering designs to help their own cities be greener.

This video reviews key points as well as pros and cons of nuclear power.

This video is one of a series produced by the Switch Energy project. It reviews the pros and cons of natural gas as a source of energy.

This video is one of a series of videos produced by the Switch Energy project. It presents the pros and cons of wind power, such as where to build, affordability, efficiency, transmission.

This video is one of a series from the Switch Energy project. It reviews the environmental impacts of various energy resources including fossil fuels, nuclear, and renewables. CO2 emissions as a specific environmental impact are discussed.

This video is one of a series of videos from the Switch Energy project. It describes three types of geothermal sources -- rare ones in which high temperatures are naturally concentrated near the surface, deep wells that require fracturing the rock and then circulating water to bring heat to the surface, and low temperature sources that use constant temperatures just below the surface to heat or cool a building. The latter two are more widely available but cost-prohibitive today.

This video addresses the importance of efficiency in providing power to an increasingly large global population.
