This audio slideshow examines the changes in the ecosystem that will occur to the Arctic due to increasing temperatures and disappearing sea ice.

This video shows some of the most dramatic fluctuations to our cryosphere in recent years, using visuals created with a variety of satellite-based data.

This web-based activity tackles the broad reasons for undertaking ocean exploration - studying the interconnected issues of climate change, ocean health, energy and human health. Students examine the types of technology ocean scientists use to collect important data.

This NASA video provides a nice overview of Earth's water cycle from the perspective of looking at Earth from space.

A short video that discusses how changing climate is affecting the population of AdÃlie penguins.

In this short video segment Native Americans talk about climate change and how it impacts their lives as they experience unexpected changes in environmental conditions. They describe observed changes in seasonality, how these changes affect ecosystems and habitats, their respect for Mother Earth, and the participation of tribal colleges in climate change research projects.

This video describes how the normal thousands-of-years-long balance of new ice creation and melting due to ocean currents has been disrupted recently by warmer ocean currents. As a result, glacier tongues that overhang the interface between ice and ocean are breaking off and falling into the ocean.

This video is part two of a seven-part National Academies series, Climate Change: Lines of Evidence. The video outlines, with the use of recent research and historical data, how we know that the Earth is warming.

Developed for Alaska Native students, this activity can be customized for other regions. Students interview elders or other long-term residents of the community to document their knowledge of local changes to the landscape and climate. Based on the information and photos they acquired from the interview, students return to photo locations to observe and record changes. Finally, they develop ideas about potential impacts of a warming climate to the ecosystem that surrounds them.

This visualization is a collection of maps, by continent, that project the impact on coastlines of a 216-foot rise in sea level, which is assumed to be the result of melting all the land ice on Earth.
