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?

CO2 effecting the weather
Recently I have been thinking a lot about how hot it has been lately, not just in the Bay Area, but all around the world. Could this change in climate be caused by the recent increase in the CO2 in the air? Scientists at NASA have been keeping a track on global warming and in the past 40 or so years the temperature has gone up from a -0.2 to a 0.7. on the temperature anomaly scale. What are your thoughts and concerns on this?
