Based on twelve years of anthropological exploration, Vincent Ialenti's Deep Time Reckoning: How Future Thinking Can Help Earth Now (MIT Press, 2020) is an engaging guide on deep time learning to reorient our understanding of time and space. As each chapter begins with creative vignettes to capture the reader's imagination and empathy and concludes with five to six reflective "reckonings," the book focuses on Finland's nuclear waste experts whose daily lives revolve around considerations of the far-flung futures and deep pasts. The main goal of chapters one and two is to pursue independent, expert-inspired, long-termist learning. The book's second goal, captured in chapters three and four, is to encourage support for highly trained, too often ignored, long-termist experts. By combating the deflation of expertise by weaving together chains of generational knowledge, Deep Time Reckoning advocates for one route of spirited and adventurous learning to rescue hopes of a safe tomorrow from the Earth's current ecological death spiral.
