This Deep Dialogue was held in honor of Larry Rosenberg, who was a founding member of the Massachusetts chapter of ECA, and served on both the leadership and research teams. Larry died of cancer on May 2, 2022, the day after he finished editing his paper on climate change: “The Climate Crisis: Impending Catastrophe and Possible Responses”. After working much of his life on a number of different causes, Larry recognized climate change as the greatest threat to humanity and the world. To honor Larry and his work and to inspire and rededicate us to the fight against climate change, this Deep Dialogue focusses on the presentation of Larry’s paper and what we can all do to continue his work. The meeting begins with remembrances of Larry from five people who knew him well and were inspired by his activism. Another group of ECA members share presenting Larrys’ paper, which can be seen as a slide show as they speak. The paper is an overview of the current state of the climate crisis, the expected consequences of it, and the many ways we can address it. The paper covers both accepted and controversial means of fighting climate change, and urges us to keep all options open, as our time for reducing catastrophic harm has grown so short. Larry’s paper is here and the video is here.
