Robert Redford calls on President Obama to have "the courage of his convictions" about carbon pollution in a new ad for the Natural Resources Defense Council.
"Four months ago, President Obama spoke of our obligation to combat climate change, saying failure to do so would betray our children and future generations," the actor, director and environmental activist said. "I just hope he has the courage of his convictions."
Redford, a trustee of the group, asks viewers to join him in urging the president to take action about climate change.
The group said the ad is slated to air this week on Washington, D.C., cable and broadcast stations and will also be promoted online through news outlets and social media sites.
