Tracing the Arctic
The land surrounding the Arctic Ocean is like a set of cradling arms, holding the ocean and the sea ice in a circular grasp.

Head for the Hills
While we spent much of our time examining corals and swamps, studying sea level and storms, we became fascinated by a simple question: How did the hills of Exuma form?
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
