Climate Literacy
About Teaching Climate Literacy

The amount of solar energy absorbed or radiated by Earth is modulated by the atmosphere and depends on its composition. Greenhouse gases—such as water vapor, carbon dioxide, and methane—occur naturally in small amounts and absorb and release heat energy more efficiently than abundant atmospheric gases like nitrogen and oxygen. Small increases in carbon dioxide concentration have a large effect on the climate system.
About Teaching Principle 2
Other materials addressing 2c
The abundance of greenhouse gases in the atmosphere is controlled by biogeochemical cycles that continually move these components between their ocean, land, life, and atmosphere reservoirs. The abundance of carbon in the atmosphere is reduced through seafloor accumulation of marine sediments and accumulation of plant biomass and is increased through deforestation and the burning of fossil fuels as well as through other processes.

Benchmarks for Science Literacy
Learn more about the Benchmarks

Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of the earth. When greenhouse gases increase, more thermal energy is trapped in the atmosphere, and the temperature of the earth increases the light energy radiated into space until it again equals the light energy absorbed from the sun.

Teaching Tips

About the Science

  • Video makes its points quickly and effectively but lacks the nuance and detail that older audiences would require.
  • Video uses the atmosphere as a blanket analogy (e.g., it shows heat bouncing off the bottom of the atmosphere, suggesting that trapped heat is generated on Earth rather than solar radiation generating the heat and the atmosphere trapping it), which may lead to misconceptions. The instructor should plan to address these mis-representations/misconceptions.
  • Comments from expert scientist: clarity of language and good use of graphics. It is not precise to say that the Sun delivers light and heat. The Sun delivers radiation (short-wave) that is used by the Earth to warm. The Earth emits thermal radiation (long-wave) that is trapped in the atmosphere.

About the Pedagogy

  • Uses an engaging cartoon format. Short and to the point regarding what is causing the Greenhouse Effect. This is a simplified approach that is very suitable for middle school students.
  • No transcript or teacher's guide is available.

Technical Details/Ease of Use

  • The animation style of this video will not suffer if projected in a classroom.
