This interactive exposes students to Earth's atmospheric gases of oxygen, carbon dioxide, and ozone. As the user manipulates the interactive to increase or decrease the concentration of each gas, explanations and images are provided that explain and visualize what the Earth would be like in each scenario.
With this carbon/temperature interactive model, students investigate the role of atmospheric carbon in the greenhouse effect using a relationship between atmospheric carbon dioxide and global temperature.
In this video, adapted from KUAC-TV and the Geophysical Institute at the University of Alaska, Fairbanks, viewers learn how one-celled organisms in permafrost may be contributing to greenhouse gas levels and global warming.
This narrated slide presentation shows the carbon cycle, looking at various parts of this biogeochemical sequence by examining carbon reservoirs and how carbon is exchanged among them and the atmosphere.
