The push for government action on climate change is like the US civil rights movement, according to former Vice President Al Gore. Both causes depended on and depend on a grassroots call to change.
Gore talked about those similarities during webcast interview with Katie Couric about his new book Our Choice, his follow-up to the film about global warming An Inconvenient Truth.
Couric referred to Gore as the "Godfather of Green" before beginning the 32-minute interview. Gore touched on the the moral issues surrounding inaction on climate change as well as cap and trade legislation specifics.
