"When you bring together lots of people and have them all contributing, you can do really remarkable things." In a piece produced for exhibit at the MIT Museum, researchers at MIT's Center for Collective Intelligence discuss their development of the Climate Collaboratorium, an online tool that enhances and supports global planning and decision-making about climate change. Aimed at both experts and the public, the Climate Collaboratorium provides a forum for discussing, testing and selecting models, plans and arguments about what humans can do about global climate change.
