DAMOCLES

This is a basic animation/simulation with background information about the greenhouse effect by DAMOCLES. The animation has several layers to it that allow users to drill into more detail about the natural greenhouse effect and different aspects of it, including volcanic aerosols and human impacts from burning fossil fuels.

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

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.

The earth's climates have changed in the past, are currently changing, and are expected to change in the future, primarily due to changes in the amount of light reaching places on the earth and the composition of the atmosphere. The burning of fossil fuels in the last century has increased the amount of greenhouse gases in the atmosphere, which has contributed to Earth's warming.

Teaching Tips

  • Educators will need to scaffold this animation to ensure that the information presented is well understood by learners.
  • When teaching about the greenhouse effect, using the term "heat," as this animation does, may confuse students, especially if they think of heat as a verb. The more accurate technical term "outgoing long wave IR radiation" may prove more difficult to convey, but ultimately is a clearer depiction of Earth's energy balance.

About the Science

  • The animation is an accurate general overview of Earth's energy balance, but educators should recognize some of the sun/Earth dynamics have been oversimplified.
  • For example, the atmosphere does filter out some short wave energy from the sun, such as extreme ultraviolet and X-rays.
  • In general, the animation provides a good overview of the incoming shortwave radiation from the sun, and Earth radiating long wave Infrared Radiation (IR) once it has been warmed by the short wave visible and IR.
  • Comment from expert scientist: Animation is a clear illustration of the physical process, but should only be used at an entry level.

About the Pedagogy

Technical Details/Ease of Use

  • Animation is simple and easy to access.
  • This animation contains a short quiz at the end.
