This video addresses two ways in which black carbon contributes to global warming. When in the atmosphere, it absorbs sunlight and generates heat, warming the air. When deposited on snow and ice, black carbon changes the albedo of the surface. The video is effective in communicating about a problem frequently underrepresented in discussions of climate change and also public health.

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 activity challenges students to try and meet the world's projected energy demand over the next century, decade by decade, by manipulating a menu of available energy sources in the online Energy lab simulator all while keeping atmospheric CO2 under a target 550ppm.

In this activity, students conduct an energy audit to determine how much carbon dioxide their family is releasing into the atmosphere and then make recommendations for minimizing their family's carbon footprint.

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 series of activities introduces students to the technologies of batteries and fuel cells. Activities include a mix of lectures, demonstrations, and lab activities.

In this activity, student teams research and develop a proposal to decrease the carbon footprint of their city's/town's public transportation system and then prepare a report that explains why their transportation plan is the best for their community.

In this activity, students conduct a life cycle assessment of energy used and produced in ethanol production, and a life cycle assessment of carbon dioxide used and produced in ethanol production.

In this hands-on activity, students examine how the orientation of a photovoltaic (PV) panel -- relative to the position of the sun -- affects the energy-efficiency of the panel.

The Climate Momentum Simulation allows users to quickly compare the resulting sea level rise, temperature change, atmospheric CO2, and global CO2 emissions from six different policy options projected out to 2100.
