What's the best way for humanity to reduce suffering from man-made global warming? Political scientist Bjorn Lomborg, author of The Skeptical Environmentalist and Cool It! has long been a vocal proponent of applying rational cost-benefit analysis to the climate problem. Criticized by some for being too economically deterministic, Lomborg agrees there is a global warming problem but disagrees with most thinkers about the best ways to address it. Watch as Lomborg discusses the latest iteration of his ongoing project to reframe the climate debate with Reason magazine science correspondent Ronald Bailey.
