Concerns about declining water supplies from glaciers have become a critical concern with global warming, especially in the Andes where large desert cities rely on glacier runoff for water. In the Cordillera Blanca, various discourses about shrinking glaciers and dwindling water supplies emerged after the 1960s, when the state hydroelectric company—first the Peruvian Santa Corporation and then Electroperú—took over disaster prevention programs and began conducting glacier research. Discourse analysis of environmental narratives shows that by the 1980s and early 1990s, the economic (water use) emphasis of these evolving glacier narratives had helped turn retreating glaciers into vanishing water towers, which facilitated company control of Andean water management. Yet glacier hazards persisted during that same period. The "glaciers as vanishing water towers" narrative, however, helped transform glaciers from natural hazards to natural resources. Analyzing glacier science and discourse illuminates the relationship between environmental discourse and management.Less

This book examines the ideal of wilderness preservation in the United States from the antebellum era to the first half of the twentieth century, showing how the early conception of the wilderness as the place where Indians lived (or should live) gave way to the idealization of uninhabited wilderness. It focuses on specific policies of Indian removal developed at Yosemite, Yellowstone, and Glacier national parks from the early 1870s to the 1930s.Less

In 1950, the Los Cedros glacial lake outburst flood destroyed the nearly constructed Cañón del Pato hydroelectric facility. President Manuel Odría responded by creating the Control Commission of Cordillera Blanca Lakes to prevent additional floods caused by climate change and glacier retreat in the Andes. The Lakes Commission achieved marked success in glacier science and glacial lake engineering during the 1950s and 60s, including a glacial lake inventory, lake classification system, and engineering projects to drain and dam glacial lakes. Government support for the Lakes Commission was often motivated by and facilitated coast-focused economic development initiatives through the Peruvian Santa Corporation rather than humanitarian concerns for vulnerable populations. These hazard mitigation programs ultimately made the state responsible for disaster prevention, and in the process facilitated nation building and gave the government more control over Andean space and resources, in part with local support because residents wanted to prevent floods.Less

As glacier retreat threatens people worldwide, this study raises crucial concerns about the successes, failures, and issues that societies might face as they grapple with climate change and shrinking glaciers. This case of climate change adaptation and hazard mitigation in response to glacier disasters over seventy years yields several broadly applicable conclusions. Residents living close to glaciers or in glacially fed watersheds endured the highest cost of glacier retreat because they lost their lives, families, and communities. Disaster responses brought new historical actors—scientists, engineers, water developers, tourists, the nation state, and most recently, the World Bank—to a region where these groups previously had little knowledge about or control over. Each group brought its own ideas about how to define, manage, and utilize the glaciated landscape. Power dynamics among the groups influenced environmental management policies and whose vision for the Andes, its glaciers, and its water ultimately won out.Less

Climate change is happening all around us, and one of the telltale signs is melting glaciers. We hear about it almost daily, pieces of ice the size of continents breaking off of Antarctica or the polar arctic ice breaking up and disappearing more and more quickly opening up navigational routes once unavailable due to thick winter ice cover. Will melting ice and glaciers so far away change our lives? Meltdown takes us deep into the cryosphere, the Earth’s frozen environment and picks apart why glacier melt caused by climate change will alter (and already is altering) the way we live around the world. From rising seas that will destroy property and flood millions of acres of coastal lands, displacing hundreds of millions of people, to rising global temperatures due to reflectivity changes of the Earth because of decreased white glacier surface area, to colossal water supply changes from glacier runoff reduction, to deadly glacier tsunamis caused by the structural weakening of ice on high mountaintops that will take out entire communities living in glacier runoff basins, to escaping methane gas from thawing frozen permafrost grounds, and changing ocean temperatures that affect jet streams and ocean water currents around the planet, glacier melt is altering our global ecosystems in ways that will drastically change our everyday lives. Meltdown takes us into the little-known periglacial environment, a world of invisible subterranean glaciers in our coldest mountain ranges that will survive the initial impacts of climate change but that are also ultimately at risk due to a warming climate. By examining the dynamics of melting glaciers, Meltdown helps us grasp the impacts of a massive geological era shift occurring right before our eyes.Less

Climate change is producing profound changes globally. This environmental history analysis offers a much needed but barely examined ground‐level study of human impacts and responses to climate change over time. It analyzes how people around Peru's Cordillera Blanca mountain range grappled with climate‐induced glacial lake outburst floods and glacier avalanches, which killed approximately 25,000 people since 1941. As survivors grieved, they formed community organizations and demanded state programs to drain dangerous glacial lakes. Yet they rejected hazard zoning in their communities. Peruvian engineers working with miniscule budgets invented innovative strategies to drain dozens of unstable lakes that continue forming in the twenty first century. But hazard mitigation, disaster responses, and climate change adaptation were never just about engineering the Andes to protect vulnerable populations. Local urban and rural populations, engineers, hydroelectric developers, irrigators, tourists, and policymakers all perceived and responded to glacier retreat differently, based on their own view of an ideal Andean world. Disaster prevention projects involved debates about economic development, state authority, race relations, class divisions, cultural values, the evolution of science and technology studies, and shifting views of nature. Over time, the influx of new groups helped transform glaciated mountains into commodities to consume. Locals lost power in the process and today comprise just one among many stakeholders—and perhaps the least powerful. Climate change transformed a region, triggering catastrophes while simultaneously jumpstarting political and economic modernization processes. This book's historical perspective illuminates these trends that would be overlooked in any scientific projections about future climate scenarios.Less

This chapter introduces the subject of Peruvian responses to climate change and ensuing glacier catastrophes from 1941 to the present. In Peru's Cordillera Blanca mountain range, which towers above the Callejón de Huaylas valley in the Ancash Department, 25,000 people have died from glacier-related disasters (glacial lake outburst floods and avalanches). The chapter places this study within current historiography on climate history, the history of science and technology, environmental history, Peruvian history, Latin American history, disaster studies, and glacier-society relations both globally and in the Andean region. The chapter then demonstrates why glacier retreat in Peru's Cordillera Blanca mountain range is an ideal case study for understanding long-term human adaptation to climate change, as well as analyzing how science evolves in societal context following climate change and natural disasters. Responses to climate change, which brought scientists and engineers to the Cordillera Blanca, unleashed a process called disaster economics: the use of catastrophes or disaster mitigation programs to promote and empower a range of economic development interests in both the public and private sectors. Climate change triggered historical processes and scientific developments far beyond the immediate disasters caused by melting glaciers.Less

The Control Commission of Cordillera Blanca Lakes, which was established in 1951 to prevent glacial lake outburst floods caused by climate change and glacier retreat in the Andes, had far-reaching effects on the economic development of Ancash and the Callejón de Huaylas. Engineers who examined glacial lakes brought development interests that had long inspired Peruvian policymakers and developers. They hoped to exploit Andean natural resources to promote national economic development and modernization. Glacial lake flood prevention programs provided a springboard for the expansion of hydroelectricity, road building, tourism, and wage labor. This process whereby disaster spurred economic development is referred to as "disaster economics," which the Lakes Commission carried out after 1951. Economic development directly and indirectly followed the science, technology, engineering, and policies implemented after catastrophes to prevent additional disasters, thereby revealing the social construction of science and engineering.Less

Two glacier avalanches from Mount Huascarán killed 4,000 people and destroyed the town of Ranrahirca and killed 15,000 people and devastated the city of Yungay in 1970, making it the most deadly glacier disaster in world history. Because these avalanches were unpredictable and uncontrollable, the Peruvian government tried more forcefully than it had during previous decades to implement hazard zoning to reduce disaster vulnerability in the Callejón de Huaylas. Local residents with different risk perceptions, however, successfully resisted zoning plans. In the process, glacier and glacial lake science became contested knowledge that various social groups sought to control. Ironically, locals opposed zoning to limit state intervention in their communities. But by inhabiting hazard zones they ultimately became even more dependent on state programs to monitor Cordillera Blanca glaciers and drain glacial lakes. As glacier experts tried to protect populations, they mediated between the centralized state and various local populations.Less

Neoliberal reforms during the 1990s transformed natural resource access and environmental management worldwide. In Peru, hydroelectricity privatization allowed Duke Energy to consolidate control over the Cañón del Pato facility on the Santa River, which is fed largely by Cordillera Blanca glacier runoff. Once Duke Energy Egenor began management in 1997, the state's hydroelectric company, Electroperú, ended its glacier monitoring and glacial lake engineering programs. This was the first break in continuous glacier disaster prevention programs since 1951. Neoliberal privatization thus heightened climate change vulnerability while simultaneously making Duke Energy a major but highly contested stakeholder in the Santa River waterscape that extended up to Cordillera Blanca glaciers. Meanwhile, threats from glacier retreat and the 1997 El Niño event continued. In 2003, fears of another glacial lake outburst flood at Lake Palcacocha above Huaraz spurred government programs to manage glacier hazards and bolstered popular protests against Duke Energy.Less

This chapter describes the physical, chemical, and biotic features of the main types of ice-based aquatic ecosystems. Dark-coloured sediments on and in ice enhance absorption of solar radiation, promote melting, and the formation of habitats of varying sizes and longevity. These range from ‘bubbles’ within glacial and perennial lake ice (~10-2 m diameter), cryoconite holes (~10-1 -100 m diameter) on ice surfaces to large melt lakes (~101 - 102 m diameter) and rivers on ice shelves and ice sheets. For the most part, the development of ice-based aquatic ecosystems depends on liquid water. Communities are predominantly microbial, with cyanobacteria and algae dominating the phototrophs, while microinvertebrates with stress-tolerate strategies (rotifers, tardigrades, and nematodes) are also present. The chapter argues that ice-based ecosystems represent important biodiversity elements within polar landscapes, and would have been essential refugia from which polar region ecosystems recovered after periods of extended glaciation.Less

The chapter summarizes the current understanding of the kelp forest ecosystems of Alaska by focusing on the key role that otters, killer whales, and man have played in the ecological organization of this ecosystem. The role of kelp, the effect of anti-predator chemistry, and sea urchin interactions are discussed. The history of the ecosystem as well as the science is covered and includes a discussion of the debate on the role of whaling in influencing otter–killer whale interactions, which may be further changing the ecology of this ecosystem.Less

This chapter discusses the creation and early management of Glacier National Park. The eastern half of Glacier National Park was once part of the Blackfeet reservation, and the tribe has long maintained that an 1895 agreement with the United States permanently reserved certain legal rights within the park area. On May 11, 1910, the Glacier National Park Bill became law, and made no mention of the rights reserved to the Blackfeet in 1895 land-cession agreement.

The eastern half of Glacier National Park was once part of the Blackfeet reservation, and the tribe has long maintained that an 1895 agreement with the United States permanently reserved certain legal rights within the park area. On May 11, 1910, the Glacier National Park Bill became law, and made no mention of the rights reserved to the Blackfeet in 1895 land-cession agreement. Nevertheless, there is no evidence that any Indians opposed the creation of the national park; a few strongly supported the new park, particularly those members of the tribal business council who saw it as potential noon to the reservation's economy.

In this chapter, Thomas E. Lovejoy reports on the documented impacts of climate change on biotas. Massive releases of greenhouse gasses by humans have altered the climate. Rapid global warming is responsible for abiotic changes such as receding of glaciers and increase in wildfires. Increased CO2 concentrations in the atmosphere have acidified the oceans. Populations, species, and ecosystems are responding to these climatic conditions. Urgent actions are needed to reverse the climatic changes.Less

This chapter explains the dynamics of Glacier Lake Outburst Floods (GLOFs) or glacier tsunamis. It describes how climate change and resulting global warming is destabilizing high mountain glaciers perched above deep glacier lakes formed by receding glaciers and subsequent melting. The chapter goes on to explain how the collapse of large pieces of ice result in mountain top born tsunami waves that destroy downstream ecosystems, people, and infrastructure and how climate change is raising the likelihood that these glacier tsunamis will occur throughout the world. It recounts historical GLOF events throughout the world, detailing the impacts and risks of these tragic events.Less

The idealization of uninhabited landscapes and establishment of the first national parks reflect important developments in late-nineteenth-century Indian policy. Although the creation of the first national parks coincided with efforts to restrict Indians to reservations and assimilate them into American society, native use and occupancy of park lands often continued unabated. This book argues that uninhabited wilderness had to be created before it could be preserved, and this type of landscape became reified in the first national parks. It also focuses on the policies of Indian removal developed at Yosemite, Yellowstone, and Glacier national parks from the 1870s to the 1930s.Less

This chapter discusses the issue of Blackfeet rights and their claims on Glacier. The issue of Blackfeet rights in the park became a protracted battle that involved various federal and state agencies, touched on key constitutional issues, and captured the attention and energy of leading preservationists. The legal complexities of the conflict that arose between the park service and the tribe and the radically different meanings that Indians and non-Indians attached to the park landscape created a unique and potent arena of contention that continues to defy resolution.Less

This chapter demonstrates that Yosemite Valley remained home to a permanent, relatively autonomous Indian village. While native residence in the valley stands in the marked contrast to other early parks, it also presents an important comparison with the experiences of Indian peoples at Yellowstone and Glacier. Such differences shed important light on Yosemite's unique history and reveal the processes by which this park was eventually made to fit the standards of the national park ideal.Less

If cooperation on cultural issues further tribal efforts to exercise some control over national park lands, this could revolutionize the way all Americans experience the wilderness. At Glacier National Park, for instance, full recognition of Blackfeet claims would make plain that the American preservationist ideal is predicated on Indian dispossession. Rather than idolize wilderness as a nonhuman landscape, where a person can be nothing more than “a visitor who does not remain,” national parks might provide new lessons about the degree to which cultural values and actions have always shaped the “natural world.”Less
