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.
In this activity, students engage in a simulation of the international negotiation process in order to convey how the international community is responding to climate change. Participants learn firsthand about the interests of different countries and the range of policy responses to mitigate future climate change.
This video describes why tropical ice cores are important and provide different information than polar ice cores, why getting them now is important (they are disappearing), and how scientists get them. The work of glaciologist Lonnie Thompson is featured, with a focus on his work collecting cores of ice from high mountain glaciers that contain significant data about past climate change.
A series of activities designed to introduce students to the role of sediments and sedimentary rocks in the global carbon cycle and the use of stable carbon isotopes to reconstruct ancient sedimentary environments. Students will make some simple calculations, think about the implications of their results, and see an optional demonstration of the density separation of a sediment sample into a light, organic and a heavier mineral fraction.
This short activity provides a way to improve understanding of a frequently-published diagram of global carbon pools and fluxes. Students create a scaled 3-D visual of carbon pools and net fluxes between pools.
This video from the U.S. National Academies summarizes the energy challenges the United States faces, the technological challenges, and the need for behavior and policy changes required to meet the challenge.
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.
