A short video on how changing climate is impacting the ecosystem and thereby impacting traditional lifestyles of the Athabaskan people of Alaska.

This is a polar map of permafrost extent in the Northern Hemisphere. A sidebar explains how permafrost, as it forms and later thaws, serves as both a sink and source for carbon to the atmosphere. Related multimedia is a slideshow of permafrost scientists from U. of Alaska, Fairbanks, collecting permafrost data in the field.

In this activity, students work through the process of evaluating the feasibility of photovoltaic solar power in 4 different US cities.

This activity is part of the Antarctica's Climate Secrets flexhibit. Students learn about and create models of glaciers and ice sheets, ice shelves, icebergs and sea ice.

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 short video features the Alaska Lake Ice and Snow Observatory Network (ALISON project), a citizen science program in which 4th and 5th graders help scientists study the relationship between climate change and lake ice and snow conditions.

This interactive contains four animated slides that introduce the greenhouse effect. An additional animation offers to 'explore more'.

This interactive graphic shows the different components of the ocean biological pump, i.e., how carbon in the form of either plankton or particles moves into the ocean's depths. The diagram illustrates the processes at the surface, 0-100 meters, 100-500 meters, and below 500 meters.

This visualization shows in five steps how ice cores provide a measure of the temperature in the past.

This engaging activity introduces students to the concept of albedo and how albedo relates to Earth's energy balance.
