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.
In this remarkably thorough account, Gertner (The Idea Factory), a New York Times Magazine contributor, narrates Greenland's history as a destination of rugged explorers and the birth site of glaciology. Gertner builds a fascinating chronology of scientific endeavor and discovery, beginning with "lunatic" Norwegian zoologist Fridtjof Nansen's 1888 trek across Greenland's frozen tundra. Scientists began flocking there in 1930 to study glaciers, eventually turning to "deep core drilling" to extract ice samples from as far as a mile down. By the 1990s, equipment sophisticated enough for "meticulous, year-by-year reading of the layers of ice" found evidence of "abrupt climate change" 17,500 years ago, in a potential omen of environmental catastrophe to come. More recently, a NASA satellite able to weigh Greenland's ice sheet discovered, alarmingly, that it is "losing well over one hundred billion tons of ice per year." Gertner demonstrates how each of these discoveries built upon previous work, cumulatively enriching the scientific understanding of climate in general and Greenland in particular. This is vital reading for anyone interested in how climate change has already affected the Earth, and how it might do so in future.)
Not just excellent, but very needed information. Congress should have to review this book so they can make policies that can help us avoid a climate disaster. 2022 is shaping up to be a real eye opener. Absolutely everyone will experience the pain of climate change, and we need to get ready by making the necessary changes. Earth is our only home. Read the book. See where we are now and make the necessary adjustments.
