In Reefs of Time, geoscientist and writer Lisa Gardiner ventures into the fossilized past of coral reefs to illuminate the urgent questions of their future. This compelling new release from Princeton University Press arrives at a moment when the world’s coral ecosystems are teetering under the weight of climate change, pollution, and overexploitation. Gardiner’s approach is both scientific and lyrical, weaving together cutting-edge research and personal fieldwork into a narrative that is as illuminating as it is moving.
Rather than dwell solely on the devastation facing reefs today, Gardiner takes readers to the “shallow end of deep time,” ancient epochs when reefs adapted to shifting seas and temperatures. From these remnants, she distills stories of endurance and transformation. The fossil record becomes not just a window into the past but a guidebook for the path forward.
Her storytelling spans continents and millennia. Readers follow Gardiner through tropical locales, where she and fellow researchers decipher the cryptic signatures etched into coral limestone. These reef remnants, some older than the dinosaurs, hold clues about how coral communities once survived dramatic environmental upheaval and how they might do so again.
Praise for Reefs of Time reflects the resonance of Gardiner’s message. Nancy Bent of Booklist describes it as “lessons from the past [that] may help save corals for the future.” Science writer Juli Berwald calls it “an elegant, urgent, and ultimately hopeful message about why our past matters so much to our future,” while Riley Black hails it as “a delight” that blends science, history, and poetic observation.
At its core, Reefs of Time is a meditation on resilience. It reframes the story of coral reefs not as one of inevitable loss, but as one of possibility if we are willing to act, and act with knowledge. It speaks to scientists, educators, policymakers, and readers who care about life beneath the waves.
Reefs of Time will be released June 10 by Princeton University Press. It is a standout contribution to marine literature, offering clarity and hope in the face of one of our era’s most pressing environmental challenges.
