Climate change is big news these days, from melting mountain glaciers to warming seas. But is the buildup of carbon dioxide in the Earth's atmosphere leading to a crisis?
That was the question at the core of a recent Oxford-style debate called Intelligence Squared U.S. The series is based on the Intelligence Squared program that began in London in 2002. Three experts argue in favor of a motion (Michael Crichton, Richard Lindzen, and Philip Stott); three others argue against it (Brenda Ekwurzel, Gavin Schmidt, and Richard Somerville).
In this debate, the proposition was: "Global Warming Is Not a Crisis." In a vote before the debate, about 30 percent of the audience agreed with the motion, while 57 percent were against and 13 percent undecided. The debate seemed to affect a number of people: Afterward, about 46 percent agreed with the motion, roughly 42 percent were opposed and about 12 percent were undecided.
