Changing Planet: Black Carbon

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, black carbon 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.

Teaching Tips

Having students study the health consequences of breathing black carbon from stoves or other sources could be a worthwhile add-on to a discussion of the production and impact of black carbon.

Researching impacts of black carbon and whether or not these impacts are occurring in the students' region of the country could also be worthwhile. For example, monitoring towers are in place for gathering data on changes in snow albedo in Grand Mesa in Colorado.
