The Ice at the End of the World


Book Description

A riveting, urgent account of the explorers and scientists racing to understand the rapidly melting ice sheet in Greenland, a dramatic harbinger of climate change “Jon Gertner takes readers to spots few journalists or even explorers have visited. The result is a gripping and important book.”—Elizabeth Kolbert, Pulitzer Prize–winning author of The Sixth Extinction NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The Washington Post • The Christian Science Monitor • Library Journal Greenland: a remote, mysterious island five times the size of California but with a population of just 56,000. The ice sheet that covers it is 700 miles wide and 1,500 miles long, and is composed of nearly three quadrillion tons of ice. For the last 150 years, explorers and scientists have sought to understand Greenland—at first hoping that it would serve as a gateway to the North Pole, and later coming to realize that it contained essential information about our climate. Locked within this vast and frozen white desert are some of the most profound secrets about our planet and its future. Greenland’s ice doesn’t just tell us where we’ve been. More urgently, it tells us where we’re headed. In The Ice at the End of the World, Jon Gertner explains how Greenland has evolved from one of earth’s last frontiers to its largest scientific laboratory. The history of Greenland’s ice begins with the explorers who arrived here at the turn of the twentieth century—first on foot, then on skis, then on crude, motorized sleds—and embarked on grueling expeditions that took as long as a year and often ended in frostbitten tragedy. Their original goal was simple: to conquer Greenland’s seemingly infinite interior. Yet their efforts eventually gave way to scientists who built lonely encampments out on the ice and began drilling—one mile, two miles down. Their aim was to pull up ice cores that could reveal the deepest mysteries of earth’s past, going back hundreds of thousands of years. Today, scientists from all over the world are deploying every technological tool available to uncover the secrets of this frozen island before it’s too late. As Greenland’s ice melts and runs off into the sea, it not only threatens to affect hundreds of millions of people who live in coastal areas. It will also have drastic effects on ocean currents, weather systems, economies, and migration patterns. Gertner chronicles the unfathomable hardships, amazing discoveries, and scientific achievements of the Arctic’s explorers and researchers with a transporting, deeply intelligent style—and a keen sense of what this work means for the rest of us. The melting ice sheet in Greenland is, in a way, an analog for time. It contains the past. It reflects the present. It can also tell us how much time we might have left.




Polar Environments and Global Change


Book Description

Surveys atmospheric, oceanic and cryospheric processes, present and past conditions, and changes in polar environments.




Vanishing Ice


Book Description

The Arctic is thawing. In summer, cruise ships sail through the once ice-clogged Northwest Passage, lakes form on top of the Greenland Ice Sheet, and polar bears swim farther and farther in search of waning ice floes. At the opposite end of the world, floating Antarctic ice shelves are shrinking. Mountain glaciers are in retreat worldwide, unleashing flash floods and avalanches. We are on thin ice—and with melting permafrost’s potential to let loose still more greenhouse gases, these changes may be just the beginning. Vanishing Ice is a powerful depiction of the dramatic transformation of the cryosphere—the world of ice and snow—and its consequences for the human world. Delving into the major components of the cryosphere, including ice sheets, valley glaciers, permafrost, and floating ice, Vivien Gornitz gives an up-to-date explanation of key current trends in the decline of ice mass. Drawing on a long-term perspective gained by examining changes in the cryosphere and corresponding variations in sea level over millions of years, she demonstrates the link between thawing ice and sea-level rise to point to the social and economic challenges on the horizon. Gornitz highlights the widespread repercussions of ice loss, which will affect countless people far removed from frozen regions, to explain why the big meltdown matters to us all. Written for all readers and students interested in the science of our changing climate, Vanishing Ice is an accessible and lucid warning of the coming thaw.




The Two-Mile Time Machine


Book Description

In the 1990s Richard B. Alley and his colleagues made headlines with the discovery that the last ice age came to an abrupt end over a period of only three years. In The Two-Mile Time Machine, Alley tells the fascinating history of global climate changes as revealed by reading the annual rings of ice from cores drilled in Greenland. He explains that humans have experienced an unusually temperate climate compared to the wild fluctuations that characterized most of prehistory. He warns that our comfortable environment could come to an end in a matter of years and tells us what we need to know in order to understand and perhaps overcome climate changes in the future. In a new preface, the author weighs in on whether our understanding of global climate change has altered in the years since the book was first published, what the latest research tells us, and what he is working on next.




The Fate of Greenland


Book Description

Viewed from above, Greenland offers an endless vista of whiteness interrupted only by scattered ponds of azure-colored melt water. Ninety percent of Greenland is covered by ice; its ice sheet, the largest outside Antarctica, stretches almost 1,000 miles from north to south and 600 miles from east to west. But this stark view of ice and snow is changing--and changing rapidly. Greenland's ice sheet is melting; the dazzling, photogenic display of icebergs breaking off Greenland's rapidly melting glaciers has become a tourist attraction. The Fate of Greenland documents Greenland's warming with dramatic color photographs and investigates Greenland's climate history for clues about what happens when climate change is abrupt rather than gradual. Geological evidence suggests that Greenland has already been affected by two dramatic changes in climate: the Medieval Warm Period, when warm temperatures in Northern Europe enabled Norse exploration and settlements in Greenland; and the Little Ice Age that followed and apparently wiped out the settlements. Greenland's climate past and present could presage our climate future. Abrupt climate change would be cataclysmic: the melting of Greenland's ice shelf would cause sea levels to rise twenty-four feet worldwide; lower Manhattan would be underwater and Florida's coastline would recede to Orlando. The planet appears to be in a period of acute climate instability, exacerbated by carbon dioxide we pour into the atmosphere. As this book makes clear, it is in all of our interests to pay attention to Greenland.--Publisher description.

Book Description

One of Springer’s Major Reference Works, this book gives the reader a truly global perspective. It is the first major reference work in its field. Paleoclimate topics covered in the encyclopedia give the reader the capability to place the observations of recent global warming in the context of longer-term natural climate fluctuations. Significant elements of the encyclopedia include recent developments in paleoclimate modeling, paleo-ocean circulation, as well as the influence of geological processes and biological feedbacks on global climate change. The encyclopedia gives the reader an entry point into the literature on these and many other groundbreaking topics.




Ice Sheets and Climate


Book Description

Climate modelling is a field in rapid development, and the fltudy of cryospheric processes has become an important part of it. On smaller time scales, the effect of snow cover and sea ice on the atmospheric circulation is of concern for long-range weather forecasting. Thinking in decades or centuries, the effect of a C02 climatic warming on the present-day ice sheets, and the resulting changes in global sea level, has drawn a lot of attention. In particular, the dynamics of marine ice sheets (ice sheets on a bed that would be below sea level after removal of ice and full isostatic rebound) is a subject of continuous research. This interest stems from the fact that the West Antarctic Ice Sheet is a marine ice sheet which, according to some workers, may be close to a complete collapse. The Pleistocene ice ages, or glacial cycles, are best characterized by total ice volume on earth, indicating that on 4 5 large time scales (10 to 10 yr) ice sheets are a dominant component of the climate system. The enormous amount of paleoclimatic information obtained from deep-sea sediments in the last few decades has led to a complete revival of iriterest in the physical aspects of the Pleistocene climatic evolution.




Camp Century


Book Description

At the height of the Cold War, the United States Army secretly began work on a base embedded deep in the Greenland ice cap: Camp Century. Officially defined as a scientific research station, this facility had an undisclosed purpose: to aim up to 600 nuclear warheads, buried in the ice, at the Soviet Union. In 1966, just six years after the camp was established, the United States gave up this provocative strategy and abandoned the base. Despite its brief life, Camp Century has been the cause of controversies from diplomatic relations between the United States and its Arctic allies, Denmark and Greenland, to the risks of radioactive waste abandoned at the site. This book is the first comprehensive account of the U.S. Army’s “city under the ice.” Beginning with the Truman administration’s vision of military superiority in the Arctic and continuing through present-day concerns over the effects of climate change, Kristian H. Nielsen and Henry Nielsen unravel the extraordinary history of this clandestine installation. Drawing on sources including top-secret memos and never-before-seen photographic evidence, they follow the intertwining threads of high-level politics, ice-core research, media representations, daily life beneath the ice, and the specter of long-buried environmental problems that will one day resurface. Camp Century reveals a hidden chapter of Cold War history—and why, as the Greenland ice cap slowly melts, this story is not yet over.




Trekking in Greenland - The Arctic Circle Trail


Book Description

At just over 100 miles long, and taking 7 to 10 days to complete, the Arctic Circle Trail crosses the largest ice-free patch of West Greenland. This splendid trekking route, lying 25-30 miles north of the Arctic Circle runs from Kangerlussuaq to Sisimiut (both of which have airport access). The trail traverses remote, empty, silent and stunningly scenic arctic tundra, and is mostly gently graded with just a few short, steep and rocky slopes. However, the landscape between the two towns of Kangerlussuaq and Sisimiut is extremely remote and those who choose to take on this route must be competely self-sufficient. The book includes plenty of practical information on what to take with you and when to go, as well as on safety, travel and accommodation. Fully illustrated with a variety of photographs and its route is highlighted on continuous trekking maps. The guide also includes an optional extension to the Greenlandic ice cap.
