This PBS video shows how Klaus Lackner, a geophysicist at Columbia University, is trying to tackle the problem of rising atmospheric CO2 levels by using an idea inspired by his daughter's 8th-grade science fair project. The video examines the idea of pulling CO2 out of the atmosphere via a passive chemical process.

In this interactive, students explore, at their own pace, how global climate change may affect health issues. Issues include airborne diseases, developmental disorders, mental health disorders, vector-borne diseases and waterborne diseases.

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

This video describes how Colorado has planned for and uses clean energy resources to reduce its carbon footprint.

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

This video highlights the Pentagon's focus on climate change as the military examines potential risks, strategic responses, and impacts of climate change on future military and humanitarian missions. In 2010, for the first time, the Pentagon focused on climate change as a significant factor in its Quadrennial Defense Review of potential risks and strategic responses. Rear Admiral David Titley, Oceanographer of the Navy, explains why the US military sees clear evidence of climate change and how those changes will affect future military and humanitarian missions.

This short, animated video describes what is meant by climate, its characteristics, and the range of impacts due to climate change. The difference between mitigation and adaptation is also discussed.

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.

In this video, students explore the work of Jay Keasling, a biologist who is experimenting with ways to produce a cleaner-burning fuel from biological matter using genetically modified microorganisms.
