'Environmental skepticism.' Bjorn Lomborg says 'Cool It' on global warming

Bjorn Lomborg calls himself a "skeptical environmentalist." Critics say he is an anti-environmentalist. In his new book, 'Cool It', he argues that global warming is not so important that tens of billions of dollars should be spent trying to prevent it. Lomborg discusses the issue with Steve Inskeep.
