Simulation: The Global Carbon Budget 1960-2100 - CLEAN
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 is at the discretion of the educator as to how the resource is used.
