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 video clip highlights the effort on by a group of young students to ban the use of plastic shopping bags in the city of Santa Monica. The video documents the effort and provides visual testimony of the effects that trash and specifically plastic bags have on the ocean ecosystem.

In this activity, students are introduced to tree rings by examining a cross section of a tree, also known as a 'tree cookie.' They discover how tree age can be determined by studying the rings and how ring thickness can be used to deduce times of optimal growing conditions. Next, they investigate simulated tree rings applying the scientific method to explore how climatic conditions varied over time.

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 visualization is an animation showing the distribution of black carbon and sulfate aerosols in the Earth's atmosphere from 01/31/2007 to 02/04/2007 and clearly shows larger amounts of aerosols and black carbon in the atmosphere above heavily populated areas.

In this activity, students use authentic Arctic climate data to unravel some causes and effects related to the seasonal melting of the snowpack and to further understand albedo.

In this hands-on activity, students will learn about dendrochronology (the study of tree rings to understand ecological conditions in the recent past) and come up with conclusions as to what possible climatic conditions might affect tree growth in their region. Students determine the average age of the trees in their schoolyard, investigate any years of poor growth, and draw conclusions about the reasons for those years.

This lesson plan engages students in a real-life exploration of climate change as it is affected by greenhouse emissions from vehicles. The aim of this activity is for students to realize the impact of vehicle use in their family and to give students the opportunity to brainstorm viable alternatives to this use.

This interactive visualization provides a clear, well-documented snapshot of current and projected values of several climate variables for local areas in California. The climate variables include observed and projected temperatures, projected snowpack, areas vulnerable to flooding due to sea level rise, and projected increase in wildfires. The projected values come from expert sources and well-established climate models.

This animated map shows prevailing surface wind direction and strength across the lower 48 states of the US.
