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 video focuses on the science of climate change and its impacts on wildlife on land and in the sea, and their habitats in the U.S. There are short sections on walruses, coral reefs, migrating birds and their breeding grounds, freshwater fish, bees, etc. Video concludes with some discussion about solutions, including reduce/recycle/reuse, energy conservation, backyard habitats, and citizen scientists.

This video illustrates the environmental challenges and achievements since Earth Day was established in 1970. It can be used as an extension or engagement resource. However, it would need to be carefully framed with the objectives of the lesson.

This music video features a rap song about some of the causes and effects of climate change with the goal of increasing awareness of climate change and how it will impact nature and humans.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

A sequence of five short animated videos that explain the properties of carbon in relationship to global warming, narrated by Robert Krulwich from NPR.

This video highlights the Pentagon's focus on climate change as the military examines potential risks, strategic responses, and impacts of climate change on future military and humanitarian missions. In 2010, for the first time, the Pentagon focused on climate change as a significant factor in its Quadrennial Defense Review of potential risks and strategic responses. Rear Admiral David Titley, Oceanographer of the Navy, explains why the US military sees clear evidence of climate change and how those changes will affect future military and humanitarian missions.

This static graph of changes in CO2 concentrations goes back 400,000 years, showing the dramatic spike in recent years.

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

This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050.
