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. Harriet Shugarman, who founded Climate Mama in 2009, joins Rose and Christine to talk 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.
