As parents we see the catastrophe of climate change looming on the horizon. Yet we may feel overwhelmed as non-scientists to provide truth to our children about what lies ahead. How do we look our kids in the eye and answer their questions with facts and  a sense of urgency while instilling hope for their future?

Harriet Shugarman, who founded Climate Mama in 2009 as a way to connect with other parents about global warming, has a conversation with Christine and Rose about her new book, "How To Talk To Your Kids About Climate Change: Turning Angst into Action" as well as what motivates her as a climate activist, and hope and grief. The first of a two-part series.
