This video describes what black carbon is, where is comes from, and how it contributes to sea ice melt and global warming.

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

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

This video focuses on the conifer forest in Alaska to explore the carbon cycle and how the forest responds to rising atmospheric carbon dioxide. Topics addressed in the video include wildfires, reflectivity, and the role of permafrost in the global carbon cycle.

This interactive visualization adapted from NASA and the U.S. Geological Survey illustrates the concept of albedo, which is the measure of how much solar radiation is reflected from Earth's surface.

This video and accompanying essay review the impacts of rising surface air temperatures and thawing permafrost on ecosystems, geology, and native populations in Alaska.

This NBC Learn video features climate scientists doing their research on Mt. Kilimanjaro to study the climate of the past. The scientists put the recently observed changes on the glacier into perspective by comparing past climate fluctuations, stressing that the current observed rate of change is unprecedented.

This video addresses two ways in which black carbon contributes to global warming - when in the atmosphere, it absorbs sunlight and generates heat, warming the air; when deposited on snow and ice, it changes the albedo of the surface. The video is effective in communicating about a problem frequently underrepresented in discussions of climate change and also public health.

This video montage of spectacular NASA satellite images set to music shows different types of ice and ice features as well as descriptions of satellite-based measurements of ice cover. Text captioning provides guidance as to issues related to changing global ice cover and its measurement.

Students perform a lab to explore how the color of materials at the Earth's surface affect the amount of warming. Topics covered include developing a hypothesis, collecting data, and making interpretations to explain why dark colored materials become hotter.
