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.

This video segment examines ethanol, a cleaner-burning fuel alternative to gasoline, and the efforts to produce it more efficiently.

This short video reviews how nations and individuals can work together to reduce the emission of CO2. It discusses strategies to reduce greenhouse gas emissions (energy conservation, renewable energies, change in energy use) and the role that government can play in this process.

In this video from Young Voices for the Planet, four middle-school girls (The Green Team) talk about their efforts to work with their peers to reduce the carbon footprint of their school and how they made the school more energy efficient.

This video and accompanying essay examine ways to reduce the environmental impact of burning coal. Two technologies are discussed: turning solid coal into a clean-burning fuel gas (syngas), and capture and storage of CO2.

This Flash-based simulation explores the relationship between carbon emissions and atmospheric carbon dioxide using two main displays: (1) graphs that show the level of human-generated CO2 emissions, CO2 removals, and the level of CO2 in the atmosphere, and (2) a bathtub animation that shows the same information as the graphs. The bathtub simulation illustrates the challenges of reducing greenhouse gas concentrations in the atmosphere.

This simulation allows the user to project CO2 sources and sinks by adjusting the points on a graph and then running the simulation to see projections for the impact on atmospheric CO2 and global temperatures.

This straightforward calculator provides conversions from one unit of energy to the equivalent amount of CO2 emission expected from using that amount.

This video features the story of a multi-generational, family-run dairy business in Oregon. The family strives for sustainability in their operations by conserving energy and reducing greenhouse gases across many aspects of their business.

This visualization is a website with an interactive calculator that allows for estimation of greenhouse gas production from croplands in the United States.
