As Prospects for CO2 Reductions Fade, Interest in Geoengineering Rises

Gregory Benford thinks Al Gore's a good guy and all, but he also thinks the star of "An Inconvenient Truth" is a little delusional. Driving a hybrid car, switching your bulbs to compact fluorescents and springing for recycled paper products are all well-meaning strategies in the fight against global warming. But as UC-Irvine physicist Benford sees it, there's a catch. Those do-gooder actions are not going to be effective enough to turn the temperature tide, and even incremental political changes like reducing greenhouse gas emissions and mining alternative fuel sources are not forward-thinking enough. "I never believed we were going to be able to thwart global warming through carbon restriction," Benford says. "Carbon restriction requires nations to subvert short- and midterm goals for a long-term goal they've read about online, and that's just not going to work."
