In this video, several scientists identify and describe examples of increasing health problems that they believe are related to climate change.

This video highlights specific climate change-related phenomena that are threatening the flora and fauna of Yellowstone National Park.

This short animated video provides a general overview of the role of carbon dioxide in supporting the Greenhouse Effect.

This video segment, adapted from Need to Know, discusses how the process of hydraulic fracturing (fracking) is used to extract natural gas and how the process may be polluting water resources with hazardous chemicals, leading to health concerns.

This fuel cell animation demonstrates how a fuel cell uses hydrogen to produce electricity, with only water and heat as byproducts. The animation consists of four parts - an introduction, fuel cell components, chemical process, and fuel cell stack.

This video introduces the concept of daylighting - the use of windows or skylights for natural lighting and temperature regulation - and how it is one building strategy that can save operating costs for homeowners and businesses.

With this carbon/temperature interactive model, students investigate the role of atmospheric carbon in the greenhouse effect using a relationship between atmospheric carbon dioxide and global temperature.

This video explores the work of environmentalist John Hart, a Professor of Environmental Science at U.C. Berkley. In the Rocky Mountains of Colorado, Dr. Hart has established an experimental laboratory in which he has artificially created and maintained a 3-degree increase in surface temperature of a plot of land, and documented the impact on plant species occupying the plot.

This interactive visualization adapted from NASA and the U.S. Geological Survey illustrates the concept of albedo, which is the measure of how much solar radiation is reflected from Earth's surface.

Students perform a lab to explore how the color of materials at the Earth's surface affect the amount of warming. Topics covered include developing a hypothesis, collecting data, and making interpretations to explain why dark colored materials become hotter.
