This animated video outlines Earth's energy. The video presents a progression from identifying the different energy systems to the differences between external and internal energy sources and how that energy is cycled and used.

C-Learn is a simplified version of a climate simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.

An interactive simulation that allows the user to adjust mountain snowfall and temperature to see the glacier grow and shrink in response.

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.

This is a figure from the 2007 IPCC Assessment Report 4 on atmospheric concentrations of carbon dioxide, methane and nitrous oxide over the last 10,000 years (large panels) and since 1750 (inset panels).

This short video, is the fifth in the National Academies Climate Change, Lines of Evidence series. It focuses on greenhouse gases, climate forcing (natural and human-caused), and global energy balance.

This animated visualization was created for the planetarium film 'Dynamic Earth'. It illustrates the trail of energy that flows from atmospheric wind currents to ocean currents.

This interactive follows carbon as it moves through various components of the carbon cycle.

This video explores what scientists know about how changes in global climate and increasing temperatures affect different extreme weather events.

This animation demonstrates the changing declination of the sun with a time-lapse animation. It shows how the shadow of a building changes over the course of a year as the declination of the sun changes.
