Slowly Moving to Protect the Environment
In some cases we do not understand the impact of human actions on the planet and we need to do more observation and analysis to understand those impacts. In other cases we don’t really know how to repair the damage once it has been done.

Exploring Ocean Turbulence: 2016 Sloan Fellow Ryan Abernathey
When you examine the behavior of the global oceans closely—really closely, at scales smaller than 100 kilometers—eddies and jets and fronts start to appear. For Ryan Abernathey, this is where ocean physics gets interesting.
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“
