It is a prominent geological feature that is almost impossible to see unless you know where to look. Hundreds of thousands of people drive across it every day. The San Andreas Fault is everywhere, and primed for a colossal quake. For decades, scientists have warned that such a sudden shifting of the Earth's crust is inevitable. In fact, it is a geologic necessity.
The San Andreas fault runs almost the entire length of California, from the redwood forest to the east edge of the Salton Sea. Along the way, it passes through two of the largest urban areas of the country--San Francisco and Los Angeles. Dozens of major highways and interstates cross it. Scores of housing developments have been planted over it. The words "San Andreas" are so familiar today that they have become synonymous with earthquake.
Yet, few people understand the San Andreas or the network of subsidiary faults it has spawned. Some run through Hollywood, others through Beverly Hills and Santa Monica. The Hayward fault slices the football stadium at the University of California in half. Even among scientists, few appreciate that the San Andreas fault is a transient, evolving system that, as seen today, is younger than the Grand Canyon and key to our understanding of earthquakes worldwide.
Why an awareness of Earth's temporal rhythms is critical to our planetary survivalFew of us have any conception of the enormous timescales in our planet's long history, and this narrow perspective underlies many of the environmental problems we are creating for ourselves. The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future. Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society. This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.
They deftly bring together findings from many disparate areas of science in a book that science buffs will find hard to put down. --Publishers WeeklyScience has worked hard to piece together the story of the evolution of our world up to this point, but only recently have we developed the understanding and the tools to describe the entire life cycle of our planet. Peter D. Ward and Donald Brownlee, a geologist and an astronomer respectively, are in the vanguard of the new field of astrobiology. Combining their knowledge of how the critical sustaining systems of our planet evolve through time with their understanding of how stars and solar systems grow and change throughout their own life cycles, the authors tell the story of the second half of Earth's life. In this masterful melding of groundbreaking research and captivating, eloquent science writing, Ward and Brownlee provide a comprehensive portrait of Earth's life cycle that allows us to understand and appreciate how the planet sustains itself today, and offers us a glimpse of our place in the cosmic order.
Rising from the Plains is John McPhee's third book on geology and geologists. Following Basin and Range and In Suspect Terrain, it continues to present a cross section of North America along the fortieth parallel--a series gathering under the overall title Annals of the Former World.
The Colorado River is an essential resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado's headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.-Mexico border where the river runs dry.
Water problems in the western United States can seem tantalizingly easy to solve: just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on.
The story Owen tells in Where the Water Goes is crucial to our future: how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert --and the disastrous consequences we face when any part of this tenuous system fails.
