Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

Norton & Company Format Available: PDF, ePub, Mobi Total Read: 73 Total Download: 257 File Size: 40,9 Mb Description: The major new work by the best-selling author of T. Rex and the Crater of Doom-a fascinating history. Walter Alvarez and his team made one of the most astonishing scientific discoveries of the twentieth century-that an asteroid smashed into the Earth 65 million years ago, exterminating the dinosaurs. Alvarez had the first glimmer of that amazing insight when he noticed something odd in a rock outcrop in central Italy. Alvarez now returns to that rich terrain, this time to take the reader on an distant past.
We encounter the volcanoes that formed the Seven Hills of Rome; the majestic limestone Apennine mountains that started to develop millions of years ago under water; the evidence that the Mediterranean Sea completely evaporated to a sunken desert, perhaps several times; and the proof that continental plates once overran one another to form telling, all major geologic episodes are as dramatic as the great impact that killed the dinosaurs, even when they happen over eons and without huge creatures to witness them.

Carroll Big History, the field that integrates traditional historical scholarship with scientific insights to study the full sweep of our universe, has so far been the domain of historians.
Famed geologist Walter Alvarez—best known for the “Impact Theory” explaining dinosaur extinction—has instead championed a science-first approach to Big History. Here he wields his unique expertise to give us a new appreciation for the incredible occurrences—from the Big Bang to the formation of supercontinents, the dawn of the Bronze Age, and beyond—that have led to our improbable place in the universe.

Did dinosaurs travel in herds? And Where and what is the Dinosaur Freeway?—this fun-filled fact-book provides a wealth of information on the lives and habits of these astonishing creatures. From the Tyrannosaurus rex to the Stegosaurus, the guide profiles numerous species, chronicling their time on earth and exploring their roles in archaeological expeditions and museums today. Delightful and intriguing, this comprehensive record includes the debates still surrounding the origins and fate of these creatures that dominated the earth for millions of years but seemed to disappear in the blink of an eye.

Deciphering the planet's history and processes could improve the ability to predict catastrophes like earthquakes and volcanic eruptions, to manage Earth's resources, and to anticipate changes in climate and geologic processes. At the request of the U.S. Department of Energy, National Aeronautics and Space Administration, National Science Foundation, and U.S. Geological Survey, the National Research Council assembled a committee to propose and explore grand questions in geological and planetary science.
This book captures, in a series of questions, the essential scientific challenges that constitute the frontier of Earth science at the start of the 21st century. Author by: Vivien Gornitz Language: en Publisher by: Columbia University Press Format Available: PDF, ePub, Mobi Total Read: 17 Total Download: 183 File Size: 47,6 Mb Description: The Earth’s climate is already warming due to increased concentrations of human-produced greenhouse gases in the atmosphere, and the specter of rising sea level is one of global warming’s most far-reaching threats. Sea level will keep rising long after greenhouse gas emissions have ceased, because of the delay in penetration of surface warming to the ocean depths and because of the slow dissipation of excess atmospheric carbon dioxide. Adopting a long perspective that interprets sea level changes both underway and expected in the near future, Vivien Gornitz completes a highly relevant and necessary study of an unprecedented age in Earth’s history. Gornitz consults past climate archives to help better anticipate future developments and prepare for them more effectively.
She focuses on several understudied historical events, including the Paleocene-Eocene Thermal Anomaly, the Messinian salinity crisis, the rapid filling of the Black Sea (which may have inspired the story of Noah’s flood), and the Storrega submarine slide, an incident possibly connected to a sea level occurrence roughly 8,000 years old. Oregon 1000 kilometers raritan. By examining dramatic variations in past sea level and climate, Gornitz concretizes the potential consequences of rapid, human-induced warming. She builds historical precedent for coastal hazards associated with a higher ocean level, such as increased damage from storm surge flooding, even if storm characteristics remain unchanged. Citing the examples of Rotterdam, London, New York City, and other forward-looking urban centers that are effectively preparing for higher sea level, Gornitz also delineates the difficult economic and political choices of curbing carbon emissions while underscoring, through past geological analysis, the urgent need to do so.
'The story of one of the greatest adventures of twentieth-century science, told by the central figure. It is a great read for both scientist and layperson.' Richard Muller, author of 'Nemesis: The Death Star.' Sixty-five million years ago, a comet or asteroid larger than Mt. Everest slammed into the Earth, causing an explosion equivalent to the detonation of a hundred million hydrogen bombs.
Vaporized impactor and debris from the impact site were blasted out through the atmosphere, falling back to Earth all around the globe. Terrible environmental disasters ensued, including a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the genera of plants and animals on Earth had perished.
This horrific story is now widely accepted as the solution to a great scientific murder mystery what caused the extinction of the dinosaurs? Rex and the Crater of Doom,' the story of the scientific detective work that went into solving the mystery is told by geologist Walter Alvarez, one of the four Berkeley scientists who discovered the first evidence for the giant impact. It is a saga of high adventure in remote parts of the world, of patient data collection, of lonely intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of intense public debate, of friendships made or lost, of the exhilaration of discovery, and of delight as a fascinating story unfolded. Controversial and widely attacked during the 1980s, the impact theory received confirmation from the discovery of the giant impact crater it predicted, buried deep beneath younger strata at the north coast of the YucatanPeninsula. The Chicxulub Crater was found by Mexican geologists in 1950 but remained almost unknown to scientists elsewhere until 1991, when it was recognized as the largest impact crater on this planet, dating precisely from the time of the great extinction sixty-five million years ago. Geology and paleontology, sciences that long held that all changes in Earth history have been calm and gradual, have now been forced to recognize the critical role played by rare but devastating catastrophes like the impact that killed the dinosaurs.
