The world is at a critical moment, when humans must grapple with thinking about the planet's oceans from ecological, physical, social, and legal perspectives. Warming ocean temperatures, changing currents, cultural displacement, Indigenous resilience, melting polar ice, habitat loss, are but a few of the global issues reflected in the planetary ocean as a front line in the unfolding drama of climate change. Re-envisioning the Anthropocene Ocean brings together leading scientists, lawyers, humanists, and Indigenous voices to tell of the ocean's precarious position in the twenty-first century. The contributors affirm that the planetary ocean is crucial to our well-being and overdue for a positive change in public action to enhance the world's resilience to climate change, ocean acidification, and other stressors. These essays engage that important work of positively re-imagining the ocean in the Anthropocene. This volume brings diverse perspectives to the planet's ocean future. New essays are contextualized with narratives woven by earlier ocean writers, showing readers how past perceptions of the ocean have led us to where we are today in terms of both problems and potential new visions. In this one volume, readers experience both the history of humanity's multi- and interdisciplinary interactions with the ocean, find new perspectives on that history, and discover ideas for looking forward.
