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.

A computer animation on the reason for the seasons. Voice-over describes the motion of Earth around the sun to show how the sun's light impacts the tilted Earth at different times of the year, causing seasonal changes.

This video is about Greenland's ice sheet, accompanied by computer models of the same, to show how the ice is melting, where the meltwater is going, and what it is doing both on the surface and beneath the ice.

This teaching activity is an introduction to how ice cores from the cryosphere are used as indicators and record-keepers of climate change as well as how climate change will affect the cryosphere.

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

This video and accompanying essay review the impacts of rising surface air temperatures and thawing permafrost on ecosystems, geology, and native populations in Alaska.

For this lesson, the guiding Concept Question is: What is climate change and how does climate relate to greenhouse gas concentrations over time? This activity is the second lesson in a nine-lesson module 'Visualizing and Understanding the Science of Climate Change' produced by the International Year of Chemistry project (2011).

A sequence of five short animated videos that explain the properties of carbon in relationship to global warming, narrated by Robert Krulwich from NPR.

In this activity, students use maps and data to learn about where and how hurricanes form and possible correlations with climate change affecting their strength.

This is a debate-style learning activity in which student teams learn about energy sources and are then assigned to represent the different energy sources. Working cooperatively, students develop arguments on the pros and cons of their source over the others.
