The video addresses impact of warming temperatures on major lakes of the world with specific focus on Lake Superior and Lake Tanganyika. It discusses the science of water stratification and its impact on lake ecosystems and on human populations whose livelihoods depend on the lakes.

This lesson guides a student inquiry into properties of the ocean's carbonate buffer system, and how changes in atmospheric carbon dioxide levels may affect ocean pH and biological organisms that depend on calcification.

In this activity, students explore the web-based U.S. Forest Service Climate Change Atlas to learn about projected climate changes in their state and how suitable habitat for tree and bird species is projected to change by 2100.

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.

In this video segment, adapted from Navajo Technical College, two Navajo Elders speak about climate change and differences in the environment that they have observed.

This video segment examines the issue of climate change from the perspective of Native Americans. The video segment was adapted from a student video produced at Haskell Indian Nations University in Lawrence, Kansas.

Learners research the effects of melting sea ice in the Bering Sea Ecosystem. They create research proposals to earn a place on the scientific research vessel Healy and present their findings and proposals to a Research Board committee.

This is the first of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. This introduction to the impacts of climate change in Alaska includes interviews with Alaska Natives, commentary by scientists, and footage from Alaska's Arctic.

This video addresses acidification of the ocean and the ecological and economic implications of the resulting pH change on marine life. It includes information about how ocean acidification resulting from increased absorption of CO2 from the atmosphere is affecting ocean species such as sea urchins and oysters. Scientists from the University of California at Santa Barbara discuss their experiments with sea creatures in acidic sea water. There is an associated lesson plan and classroom activity that has students test the effects of CO2 on water pH.

This interactive world map shows the impact of a global temperature rise of 4 degrees Celsius on a variety of factors including agriculture, marine life, fires, weather patterns, and health. Hot Spots can be clicked on to get more specific information about the problems in different regions.
