A Natural History of Time
Pascal Richet
University of Chicago Press, 2007

The quest to pinpoint the age of the Earth is nearly as old as humanity itself. For most of history, people trusted mythology or religion to provide the answer, even though nature abounds with clues to the past of the Earth and the stars. In A Natural History of Time, geophysicist Pascal Richet tells the fascinating story of how scientists and philosophers examined those clues and from them built a chronological scale that has made it possible to reconstruct the history of nature itself.

Richet begins his story with mythological traditions, which were heavily influenced by the seasons and almost uniformly viewed time cyclically. The linear history promulgated by Judaism, with its story of creation, was an exception, and it was that tradition that drove early Christian attempts to date the Earth. For instance, in 169 CE, the bishop of Antioch, for instance declared that the world had been in existence for “5,698 years and the odd months and days.”

Until the mid-eighteenth century, such natural timescales derived from biblical chronologies prevailed, but, Richet demonstrates, with the Scientific Revolution geological and astronomical evidence for much longer timescales began to accumulate. Fossils and the developing science of geology provided compelling evidence for periods of millions and millions of years—a scale that even scientists had difficulty grasping. By the end of the twentieth century, new tools such as radiometric dating had demonstrated that the solar system is four and a half billion years old, and the universe itself about twice that, though controversial questions remain.

The quest for time is a story of ingenuity and determination, and like a geologist, Pascal Richet carefully peels back the strata of that history, giving us a chance to marvel at each layer and truly appreciate how far our knowledge—and our planet—have come.

New Earth Histories
Geo-Cosmologies and the Making of the Modern World
Edited by Alison Bashford, Emily M. Kern, and Adam Bobbette
University of Chicago Press, 2023
A kaleidoscopic rethinking of how we come to know the earth.
 
This book brings the history of the geosciences and world cosmologies together, exploring many traditions, including Chinese, Pacific, Islamic, South and Southeast Asian conceptions of the earth’s origin and makeup. Together the chapters ask: How have different ideas about the sacred, animate, and earthly changed modern environmental sciences? How have different world traditions understood human and geological origins? How does the inclusion of multiple cosmologies change the meaning of the Anthropocene and the global climate crisis? By carefully examining these questions, New Earth Histories sets an ambitious agenda for how we think about the earth.
 
The chapters consider debates about the age and structure of the earth, how humans and earth systems interact, and how empire has been conceived in multiple traditions. The methods the authors deploy are diverse—from cultural history and visual and material studies to ethnography, geography, and Indigenous studies—and the effect is to highlight how earth knowledge emerged from historically specific situations. New Earth Histories provides both a framework for studying science at a global scale and fascinating examples to educate as well as inspire future work. Essential reading for students and scholars of earth science history, environmental humanities, history of science and religion, and science and empire.

The Next Supercontinent
Solving the Puzzle of a Future Pangea
Ross Mitchell
University of Chicago Press, 2023

An internationally recognized scientist shows that Earth’s separate continents, once together in Pangea, are again on a collision course.

You’ve heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents, but what about its predecessors, Rodinia or Columbia? These “supercontinents” from Earth’s past provide evidence that land repeatedly joins and separates. While scientists debate what that next supercontinent will look like—and what to name it—they all agree: one is coming.

In this engaging work, geophysicist Ross Mitchell invites readers to remote (and sometimes treacherous) lands for evidence of past supercontinents, delves into the phenomena that will birth the next, and presents the case for the future supercontinent of Amasia, defined by the merging of North America and Asia. Introducing readers to plate tectonic theory through fieldwork adventures and accessible scientific descriptions, Mitchell considers flows deep in the Earth’s mantle to explain Amasia’s future formation and shows how this developing theory can illuminate other planetary mysteries. He then poses the inevitable question: how can humanity survive the intervening 200 million years necessary to see Amasia?

An expert on the supercontinent cycle, Mitchell offers readers a front-row seat to a slow-motion mystery and an ongoing scientific debate.

The Next Tsunami
Living on a Restless Coast
Bonnie Henderson
Oregon State University Press, 2014
On a March evening in 1964, ten-year-old Tom Horning awoke near midnight to find his yard transformed. A tsunami triggered by Alaska’s momentous Good Friday earthquake had wreaked havoc in his Seaside, Oregon, neighborhood. It was, as far as anyone knew, the Pacific Northwest coast’s first-ever tsunami.

More than twenty years passed before geologists discovered that it was neither Seaside’s first nor worst tsunami. In fact, massive tsunamis strike the Pacific coast every few hundred years, triggered not by distant temblors but by huge quakes less than one hundred miles off the Northwest coast. Not until the late 1990s would scientists use evidence like tree rings and centuries-old warehouse records from Japan to fix the date, hour, and magnitude of the Pacific Northwest coast’s last megathrust earthquake: 9 p.m., January 26, 1700, magnitude 9.0—one of the largest quakes the world has known. When the next one strikes—this year or hundreds of years from now—the tsunami it generates is likely to be the most devastating natural disaster in the history of the United States.

In The Next Tsunami, Bonnie Henderson shares the stories of scientists like meteorologist Alfred Wegener, who formulated his theory of continental drift while gazing at ice floes calving from Greenland glaciers, and geologist Brian Atwater, who paddled his dented aluminum canoe up coastal streams looking for layers of peat sandwiched among sand and silt. The story begins and ends with Tom Horning, who grew up to become a geologist and return to his family home at the mouth of the river in Seaside—arguably the Northwest community with the most to lose from what scientist Atwater predicts will be an “apocalyptic” disaster. No one in Seaside understands earthquake science—and the politics and complicated psychology of living in a tsunami zone—better than Horning.

Henderson’s compelling story of how scientists came to understand the Cascadia Subduction Zone—a fault line capable of producing earthquakes even larger than the 2011 Tohoku quake in Japan—and how ordinary people cope with that knowledge is essential reading for anyone interested in the charged intersection of science, human nature, and public policy

Novel Science
Fiction and the Invention of Nineteenth-Century Geology
Adelene Buckland
University of Chicago Press, 2013
Novel Science is the first in-depth study of the shocking, groundbreaking, and sometimes beautiful writings of the gentlemen of the “heroic age” of geology and of the contribution these men made to the literary culture of their day. For these men, literature was an essential part of the practice of science itself, as important to their efforts as mapmaking, fieldwork, and observation. The reading and writing of imaginative literatures helped them to discover, imagine, debate, and give shape and meaning to millions of years of previously undiscovered earth history.
           
Borrowing from the historical fictions of Walter Scott and the poetry of Lord Byron, they invented geology as a science, discovered many of the creatures we now call the dinosaurs, and were the first to unravel and map the sequence and structure of stratified rock. As Adelene Buckland shows, they did this by rejecting the grand narratives of older theories of the earth or of biblical cosmogony: theirs would be a humble science, faithfully recording minute details and leaving the big picture for future generations to paint. Buckland also reveals how these scientists—just as they had drawn inspiration from their literary predecessors—gave Victorian realist novelists such as George Eliot, Charles Kingsley, and Charles Dickens a powerful language with which to create dark and disturbing ruptures in the too-seductive sweep of story.
