Content Cover Image

SUMMARY

This activity has been selected for inclusion in the CLEAN Collection based on the following review comments:

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.

About the Science
  • An interactive way to look at the global carbon cycle and its relationship with global warming.
  • The estimated global temperature response is a rough scaling based upon average IPCC AR4 (2007) model sensitivity to atmospheric CO2.
  • Students can adjust CO2 emissions from fossil fuels and land use (sources) and uptake from oceans and land (sinks).
  • Passed initial science review - expert science review pending.

ACTIVITY DESCRIPTION AND TEACHING MATERIALS

Simulation >> The Global Carbon Budget 1960-2100

Technical Details/Ease of Use
  • The teacher may need to explain to students that they must select a button under sources or sinks before they can manipulate the graph on the left.
  • Good introductory material on home page http://carboncycle.aos.wisc.edu/. Easy to use and analyze the results.

TEACHING NOTES / CONTEXT FOR USE

  • Direct students to watch each projection at least twice: Once while focusing on the graph being produced, and then again to watch changes in the graphic at the bottom of the page.
  • Excellent graphic that shows changes in the carbon cycle given different scenarios of fossil fuel use in the future.
  • Students use the interactive as a tool to predict what temperature conditions on Earth will be given different levels of carbon injected into the atmosphere.
  • Shows the complexities of climate change and the usefulness and limitations of modeling.

ASSESSMENT

Assessment is at the discretion of the educator as to how the resource is used.
