You might remember the Tällberg Foundation from our news this past Monday, when they coordinated over 150 signatories endorsing the 350 ppm goal in full page ads around the world. Well, those ads were in fact only a kickoff to their yearly Tällberg Forum, where world leaders, scientists, activists and experts gather to discuss the pressing issues of the day. This year, along with James Hansen and Desmond Tutu, our own Bill McKibben has been invited to speak. If you’ve got a free moment, check out some of the events, in this video archive. Bill spoke on Sunday, June 29, at 8.30AM Central European Summer Time (CEST) for a discussion on public opinion, and at 4:00PM (16.00) CEST for closing remarks.
