There is about a 40-percentage point gap between Democrats and Republicans in their concern for climate change. New research suggests a solution for working around this deep-seated partisanship.

Guests include Megan Mullin, an associate professor of environmental politics at the Nicholas School of the Environment at Duke University and former Republican Congressman Bob Inglis.

This is the first of a four-part series on understanding and dealing with a changing climate.
