This is an interactive visualization of the Carbon Cycle, through short-term and long-term processes.

An engaging and informational video describing the history of our knowledge about climate change.

This video succinctly explains the mechanism of the natural greenhouse effect and the cause of global climate change (anthropogenic global warming). It is short, basic, and to the point. It's also available in 12 languages!

This static graph of changes in CO2 concentrations goes back 400,000 years, showing the dramatic spike in recent years.

This video provides an overview of changes happening in the Arctic.

This online quiz tests knowledge about climate change, its impacts, how we know about earth's climate, and potential solutions.

This interactive animation focuses on the carbon cycle and includes embedded videos and captioned images to provide greater clarification and detail of the cycle than would be available by a single static visual alone.

This video is narrated by climate scientist Richard Alley. It examines studies US Air Force conducted over 50 years ago on the warming effects of CO2 in the atmosphere and how that could impact missile warfare. The video then focuses on the Franz Josef glacier in New Zealand; the glacier is used to demonstrate a glacier's formation, depth of snow fall in the past, and understand atmospheric gases and composition during the last Ice Age. Supplemental resources are available through the website.

In this audio slideshow, an ecologist from the University of Florida describes the radiocarbon dating technique that scientists use to determine the amount of carbon within the permafrost of the Arctic tundra. Understanding the rate of carbon released as permafrost thaws is necessary to understand how this positive feedback mechanism is contributing to climate change that may further increase global surface temperatures.

NASA produced white-board animation video explains key concepts about the role and source of carbon dioxide as a greenhouse gas.
