The "good news," perversely enough, had to do with the recession. In the afternoon plenary session, Richard Levin, president of Yale University, said that the financial crisis has a silver lining -- it provides a chance for transformation that in better times might not be possible. Retrofitting buildings, mass transit, vehicle fuel efficiency, smart grids, wind, solar, biofuels: all will stimulate the world economy, Levin said. The timing of COP 15, then, is oddly perfect. As Levin put it, COP 15 is a "critical opportunity not to be missed."
