This site provides information about the effects of carbon dioxide and sulfur dioxide volcanic emissions on global climate. Helpful diagrams depict the chemical processes involved in atmospheric cooling and historical examples are cited. The 1991 eruption of Mt. Pinatubo in used as a case study. The site also provides links to references cited and additional resources. Full description.

This NASA site explains the three major types of atmospheric aerosols - volcanic emissions, desert dust, and anthropogenic aerosols - and how they affect global climate. The site discusses the generation and atmospheric distribution of these aerosols, as well as the chemical and physical processes by which they create global cooling. Full description.

This site features QuickTime and Flash animations that illustrate various aspects of ocean-related activity, including normal, El Nino, and La Nina conditions, ocean plant productivity, causes of upwelling, ocean current patterns, and the origin of tides. The animations can be paused and rewound to stress important points. These resources are suitable for use in lectures, labs, or other teaching activities. ... Full description.
