This video features three faculty from the University of Colorado, Boulder (Beth Osnes, Max Boykoff and James White) and CU students taking action with others to help mitigate climate change at a local level - making personal decisions about energy use and family size, educating the university community about actions that individuals can take, and developing materials to build sustainable housing.

This animated slideshow introduces biodiesel as a fuel alternative. With concern about the use of petroleum-based fuels at an all-time high, biodiesel is experiencing a popularity surge. And algaeâotherwise known to some as pond scumâ are grabbing headlines as the next potential biodiesel superstar. But how and why do algae make oil? And why do they make so much of it? In this audio slide show, U.C. Berkeley's Kris Niyogi describes the process and its potential.

This interactive contains four animated slides that introduce the greenhouse effect. An additional animation offers to 'explore more'.

This graphic contains ocean heat content (OHC) anomaly trends from 1945 to 2009 for the top 700 meters of the ocean. It is composed of long-term datasets from seven different references. The graphic can be manipulated and downloaded as a picture.

In this activity, students examine the energy required to make a cheeseburger, calculate its associated carbon footprint, and discuss the carbon emissions related to burger production. The activity is geared toward Canadian students but can be customized to the consumption patterns and carbon footprint of American students since the resource references the amount of burgers consumed by Americans in addition to Canadians.

This video provides a comprehensive introduction to the role of coral reefs, the physiology of corals, and the impacts of both ocean warming and acidification on coral survival. It highlights experts from the Bermuda Institute of Ocean Sciences and the University of Miami.

In this activity, students use NASA satellite data to explore the seasonal changes in sea surface temperatures of the Gulf Stream. Students use NASA's Live Active Server (LAS) to generate data of sea surface temperatures in the Gulf Stream, which they then graph and analyze.

This in-depth interactive slideshow about how climate models work is embedded with a lot of background information. It also describes some of the projected climate change impacts to key sectors such as water, ecosystems, food, coasts, health. (scroll down page for interactive)

This video from NASA features scientists who describe the role of salt in the oceans and global oceanic circulation, especially the effect of salinity on the density of water and its global circulation, with reference to global climate change.

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.
