- It may be useful, depending on the grade level of students, for instructor to pause at each graph and check that students understand what is being illustrated.
About the Science
- Visualization is a series of animated graphs, that, individually and combined, illustrate how fluctuations in earth's orbit, solar temperature variability, and volcanic eruptions over the period 1880-2005 do not account for the rise in average atmospheric temperature during the same period. Graphs of changes in land use (primarily deforestation) and ozone and aerosol pollution (all human-caused) are included, presenting minimal impact. Only changes in GHG emissions track the increase in average global atmospheric temperature.
- NASA GISS computer ModelE2 provides the data behind the visualization.
Comments from expert scientist:
Excellent resource when presenting to general audiences or climate skeptics
- Excellent breakdown of all potential natural and anthropogenic factors to global warming. Brief explanation of what there overall effects are on the planet.
About the Pedagogy
- Short text passage accompanies each graph and summarizes the net effect of factors.
- Each step in the animation is explained concisely so students know what the factors are while the graph is being produced.
- A great summary of the natural causes of climate change and how their effect on global temperature changes compares to that of CO2 emission.
