Ends of the World

This work of popular science investigates Earth's five great mass extinctions, the catastrophes in which most of the planet's species disappeared within a geological instant. Traveling to fossil sites from South Africa to the Palisades above the Hudson River, the book reconstructs each die-off as a kind of crime scene, reading the rock and fossil record for clues to what went wrong. A clear pattern emerges: again and again, sudden disruptions to the planet's carbon cycle drove violent swings in climate and ocean chemistry, acidifying seas, starving them of oxygen, and overheating the world until life collapsed. Drawing on interviews with paleontologists and geochemists, the narrative moves from the deep past toward the present, where the same chemistry that ended earlier worlds is being run in reverse by human carbon emissions. Yet the story is not only one of destruction. It is also about resilience, the strange persistence of life and its capacity to recover and diversify after near-total ruin. Written with energy and a strong sense of deep time, the book frames the modern climate crisis against the long history of planetary catastrophe, arguing that Earth's distant past offers the most honest preview of where the present may lead.
