In a recent article in The Guardian, scientists warn that the Intergovernmental Panel on Climate Change (IPCC) substantially underestimated the severity of global warming over the rest of the century in their most recent report on climate change. In reponse, former US vice-president Al Gore called for a globally coordinated stimulus to tackle climate change. The DVD Six Degrees Could Change the World explores what each rising, and critical, degree could mean for the future of our people and planet. Photo courtesy of AP Photo.
