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, it 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 simulation allows the user to project CO2 sources and sinks by adjusting the points on a graph and then running the simulation to see projections for the impact on atmospheric CO2 and global temperatures.

This hands-on activity introduces students to the process of fermenting different carbohydrate sources into ethanol. Teachers demonstrate yeasts' inability to metabolize certain food sources.

This is a collection of five short videos that show how climate change is affecting fishing, native populations and access for the oil and gas industry in the Arctic. The videos include personal reflections by writers Andrew C. Revkin and Simon Romero, scientists, and residents about their experience of the impacts of the climate change in the Arctic.

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.

An activity focusing on black carbon. This activity explores the impacts of the use of wood, dung, and charcoal for fuel, all which generate black carbon, in developing countries.

This video discusses the social and economic impacts (worldwide and in the US) of sea level rise caused by global warming (aired April 1, 2011).

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

This video highlights the benefits of electric vehicles, including improved fuel efficiency, reduced emissions, and lower maintenance costs.

In this activity students make biodiesel from waste vegetable oil and develop a presentation based on their lab experience. Parts of the activity include creation of bio-diesel from clean vegetable oil, creation of bio-diesel from waste vegetable oil, chemical analysis of biodiesel, purification of biodiesel, and creation of soap from glycerin.
