In this video, a PhD Student from the University of Maine explains how ice cores are used to study global climate change.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

This video is the second of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. The video highlights the marine mammals and birds and how they depend on Arctic sea ice, as well as questions about how these animals will cope in the face of climate change.

An applet about the Milankovitch cycle that relates temperature over the last 400,000 years to changes in the eccentricity, precession, and orbital tilt of Earth's orbit.

In this activity students research the inter-dependencies among plants and animals in an ecosystem and explore how climate change might affect those inter-dependencies and the ecosystem as a whole.

This video introduces phytoplankton - the base of the marine food web, the source of half of the oxygen on Earth, and an important remover of CO2 from the atmosphere. The video also explains how satellites are used to monitor phytoplankton and how warming waters and acidification negatively affect phytoplankton.

In this experiment, students will observe two model atmospheres: one with normal atmospheric composition and another with an elevated concentration of carbon dioxide. These two contained atmospheres will be exposed to light energy from a sunny window or from a lamp. The carbon dioxide is produced by a simple reaction and tested using bromothymol blue (BTB).

This board game, designed for middle school students, introduces the concepts of energy use in our lives and the real impact that personal choices can have on our energy consumption, energy bills, and fuel supply.

In this video segment, adapted from a student video produced at Northwest Indian College in Bellingham Washington, Native American elders discuss the impact of climate change on salmon populations and the importance of restoring balance in the natural world.
