Most of us recognise that climate change is real, and yet we do nothing to stop it. What is the psychological mechanism that allows us to know something is true but act as if it is not? George Marshall, current director of projects at the Climate Outreach Information Network, explains why. George Marshall, writer and co-founder of the Climate Outreach Information Network talked about why our brains are wired to ignore environmental threats at TEDxWWF. Brussels, 13 October 2014. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
