Rebecca Solnit, the author of books including “A Paradise Built in Hell” (2009) and “Orwell’s Roses” (2021) and the co-editor of the new collection of essays “Not Too Late: Changing the Climate Story from Despair to Possibility,” discusses the long view as a “mind-blowing” way of looking at the world, why the majority of people tend to be altruistic and resourceful in a disaster, and why the climate crisis requires eschewing a scarcity mindset for one of abundance.
