- These graphs can can complement discussions and activities around anthropogenic greenhouse gas emissions and their heat trapping qualities.
About the Science
- This figure contains three graphs from the 2007 IPCC AR4 Working Group I: The Physical Science Basis.
- Titled "Changes in Greenhouse Gases from Ice Core and Modern Data", this figure examines atmospheric concentrations of CO2, CH4 and N2O and the related radiative forcing of each.
- Comments from expert scientist: The figure is valuable for showing the dramatic increase in atmospheric CO2, methane and nitrous oxide concentrations over the past 100 years relative to Holocene values. The figure also shows, on a second y-axis, the radiative forcing due to each of the greenhouse gases which can be helpful in demonstrating that even small concentrations of these gases can have a large impact.
About the Pedagogy
- There is no pedagogic scaffolding, but this graphic can complement related information and activities.
