Student Footprints
Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.
Do you see differences across the globe? If so, why do you think those differences exist?
Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?

Wait so do greenhouse gases stay in the atmosphere longer than others?

I remember reading that methane stays in the atmosphere for around 12 years before breaking down whereas carbon dioxide can last anywhere from 5 - 200 years. I'm not quite sure on any of the others.
