When drawing political lines, climate change is a topic that’s usually sticks to the script. Many on the right say global warming isn’t a reality, while proponents on the left warn us that it’s changing our planet as we speak.

Author George Marshall, Karen Weigert, Chief Sustainability Officer for the City of Chicago and Terry Bergdal, CEO of the Institue of Cultural Affairs joins us.
