On January 10-11, 2013, a distinguished group of practitioners and scholars gathered at the University of Toronto's Munk School of Global Affairs in an attempt to start a new conversation about the politics and governance of climate change. The Post-Kyoto era has now begun, with little fanfare, some anxiety, and considerable, unaddressed challenges. While the failure to negotiate a strong Kyoto successor deserves our attention, it doesn't change the science, global concern, or public demands for action. The scope of the mismatch between what we need to do--get on the path to decarbonization--and what the world has agreed to do--not much--is painfully clear. We simply are not on the path to transformation needed to meet decarbonization goals. This is the challenge we face and the conversation to which this workshop aimed to contribute.
