Witnessing for the middle seeks to depolarize contentious public issues and to create effective coalitions. It reveals neglected facets of a problem, clarifies the stakes, reduces hype, and facilitates the engagement of people largely on the sidelines. Regarding climate change, many forms of middle-building are under way, notably including the scenario-making that reveals alternative pathways to some specific goal. This essay explores two additional vital middle-building conversations, both focused on the goals themselves. One conversation addresses how to learn faster about how our planet can harm us. The other conversation focuses on the various ways that we can harm ourselves while pursuing nominal solutions to climate change. The two themes are complementary. The more plausible the risks of dangerous climate change, the stronger the case for risky solutions.
