Over the weekend, President-Elect Barack Obama appointed John Holdren as his Science Adviser, a move applauded by many environmentalists. Holdren is director of the Woods Hole Research Center and teaches at Harvard. Corporate Watchdog Radio has featured him twice. We aired part of his opening address at the 2008 UN Investor Summit on Climate Risk. And in September 2006, he talked with us about the pros and cons of nukes as a low-carbon solution to the climate crisis. This week, we reprise these shows to give a sense of Holdren’s opinions.
