To have any shot at building the clean energy economy needed to turn back climate change, we will have to overcome the inflexive resistance to development of the projects and resources that will facilitate that transition. Perhaps the most trusted person to deliver that message to environmentalists is climate champion Bill McKibben, and that's exactly what he did in a recent piece for Mother Jones. He joins this month's national call days before our volunteers go to lobby on Capitol Hill. Bill is an author, educator, and environmentalist, who helped found 350.org, the first global grassroots climate campaign, and he recently helped found Third Act, a progressive organizing movement for people over the age of 60.
