Environmental Technology Expert David Keith on The Colbert Report

An expert in energy and environmental technology, David Keith studies our climate and the many ideas we’ve come up with to fix it. A wildly original thinker, he challenges us to look at climate solutions that may seem daring, sometimes even shocking. Currently a professor at Harvard University, David was listed as one of Time magazine’s “Heroes of the Environment” in 2009, and advises on a number of high-profile advisory panels around the world. His new book, A Case for Climate Engineering, has recently debuted, and David had the chance to sit down with Stephen Colbert to talk about his solution to global warming (watch above).
