Climate Literacy
About Teaching Climate Literacy

Airborne particulates, called "aerosols," have a complex effect on Earth’s energy balance: they can cause both cooling, by reflecting incoming sunlight back out to space, and warming, by absorbing and releasing heat energy in the atmosphere. Small solid and liquid particles can be lofted into the atmosphere through a variety of natural and man-made processes, including volcanic eruptions, sea spray, forest fires, and emissions generated through human activities.
About Teaching Principle 2
Other materials addressing 2e
The interconnectedness of Earth’s systems means that a significant change in any one component of the climate system can influence the equilibrium of the entire Earth system. Positive feedback loops can amplify these effects and trigger abrupt changes in the climate system. These complex interactions may result in climate change that is more rapid and on a larger scale than projected by current climate models.
About Teaching Principle 2
Other materials addressing 2f
Observations, experiments, and theory are used to construct and refine computer models that represent the climate system and make predictions about its future behavior. Results from these models lead to better understanding of the linkages between the atmosphere-ocean system and climate conditions and inspire more observations and experiments. Over time, this iterative process will result in more reliable projections of future climate conditions.
About Teaching Principle 5
Other materials addressing 5c
Scientists have conducted extensive research on the fundamental characteristics of the climate system and their understanding will continue to improve. Current climate change projections are reliable enough to help humans evaluate potential decisions and actions in response to climate change.

Benchmarks for Science Literacy
Learn more about the Benchmarks

Computer modeling explores the logical consequences of a set of instructions and a set of data. The instructions and data input of a computer model try to represent the real world so the computer can show what would actually happen. In this way, computers assist people in making decisions by simulating the consequences of different possible decisions.

Teaching Tips

  • Educator will need to work with this model thoroughly before asking students to use the simulation.
  • It might be good to include a lesson period that focuses on solutions after teaching about climate modeling. The questions the students ask in the video demonstrate that the scenarios described by climate scientists cause anxiety.
  • Run the simulation with the entire class before letting them use the simulation by themselves. Use this time to discuss what the yellow and red arrows represent and their behavior. Will also need to have a discussion about aerosols from erupted volcanoes.
  • Good for professional development of teachers.

About the Science

  • Interactive modeling activity simulating the interactions among different sets of variables: carbon dioxide vs temperature; carbon dioxide, water vapor, and temperatures; cloud cover, carbon dioxide, and temperature; and human GHG emissions, GHGs, and temperatures. There is a temperature anomaly time-series video from 1800 to 2000 and a video of a lecture to a science class by a paleoclimatologist.
  • No original data or links to the algorithms that went into the model are provided.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • Simple climate model lets students experiment with the influence of different parameters and the guiding questions prompt students to experiment with the model. Video is well done for target audience
  • Educator will need to work with this model thoroughly before asking students to use the simulation.
  • See Oct 2012 "Science Teacher" -modeling climate change article.

Technical Details/Ease of Use

  • Model lacks a key that explains what the different parts of the model stand for. It is straightforward to figure out what is meant by the pictograms, but it would be good for the educator to produce a legend and hand it out to students.
