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.

This high-resolution narrated video shows levels and movements of CO2 globally through the course of a year.

In this Earth Exploration Toolbook chapter, students select, explore, and analyze satellite imagery. They do so in the context of a case study of the origins of atmospheric carbon monoxide and aerosols, tiny solid airborne particles such as smoke from forest fires and dust from desert wind storms. They use the software tool ImageJ to animate a year of monthly images of aerosol data and then compare the animation to one created for monthly images of carbon monoxide data. Students select, explore, and analyze satellite imagery using NASA Earth Observatory (NEO) satellite data and NEO Image Composite Explorer (ICE) tool to investigate seasonal and geographic patterns and variations in concentration of CO and aerosols in the atmosphere.

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

This is a photo essay linked to a New York Times story about climate-related stressors on forests -- including mountain pine beetles, forest fires, forest clearance, and ice storms -- and the importance of protecting forests as an important carbon sink.

This is an animation from the US Environmental Protection Agency's Students Guide to Global Climate Change, one of a series of web pages and videos about the basics of the greenhouse effect.

In this classroom activity, students access sea surface temperature and wind speed data from a NASA site, plot and compare data, draw conclusions about surface current and sea surface temperature, and link their gained understanding to concerns about global climate change.

This video provides a good overview of ice-albedo feedback. Albedo-Climate feedback is a positive feedback that builds student understanding of climate change.

In this video, a PhD Student from the University of Maine explains how ice cores are used to study global climate change.

In this activity, students use authentic Arctic climate data to unravel some causes and effects related to the seasonal melting of the snowpack and to further understand albedo.
