If you're looking for a pretty wide-ranging discussion of climate change and sustainability, consider Climatographer director Mark Trexler's conversation with Jen Novakovich on her EcoWell podcast.
Jen's primary audience is the cosmetics industry, so at first glance perhaps it doesn't sound like it is directly related to climate change policy issues. But take a listen -- it was a fun and wide-ranging conversation about why we are where we are on climate change, and what might move us forward.
