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?

The Truth About Climate Change
Climate change is real and it is a valid concern. Through collecting data of the Earth's temperature we notice that the temperature has increased drastically. In the 1880's Hadley Climate Research Unit reports the temperature anomaly was -.2. Now the temperature anomaly is + .7. That is a .9 increase, this supports that climate change is real and the temperature is increasing. Some effects of temperature increase are Polar ice caps melting which will cause sea levels to rise. Cities would be completely submerged all because of our overproduction of Greenhouse gases.
