Advocate, independent adviser, social entrepreneur and award-winning authority in the global climate change movement James Cameron is a believer in the power of enterprise to solve the most complex and urgent global problems. In this interactive conversation with Green Templeton postgraduate student Emily Buckley, he’ll discuss his own career of innovative interventions on climate change and biodiversity, highlight what needs to be done next, and propose a ‘possibilist’ way forward that avoids both climate despair and undue techno-optimism.
