'Climate of Doubt' Examines Politics vs. Climate Change

On Frontline Tuesday, "Climate of Doubt" looks at how groups of global warming skeptics changed the political climate on the issue.
NewsHour's Hari Sreenivasan spoke with journalist John Hockenberry, host of the Frontline film, about why climate change has been left out of the political arena this election.
