Melt Water Retention Processes in Snow and Firn on Ice Sheets and Glaciers: Observations and Modeling
Melt takes place where the surface of glaciers or ice sheets interacts with the atmosphere. While the processes governing surface melt are fairly well understood, the pathways of the meltwater, from its origin to the moment it leaves a glacier system, remain enigmatic. It is not even guaranteed that meltwater leaves a glacier or ice sheet. On Greenland, for example, only slightly more than 50% of the meltwater runs off. The remainder mostly refreezes within the so-called firn cover of the ice sheet. This eBook contains 11 studies which tackle the challenge of understanding meltwater retention in snow and firn from various angles. The studies focus both on mountain glaciers and on the Greenland ice sheet and address challenges such as measuring firn properties, quantifying their influence on meltwater retention, modelling firn processes and meltwater refreezing as well as unravelling the mechanisms within the recently discovered Greenland firn aquifers.
Perils of Plenty
Among scholars who focus on the politics of natural resources, conventional wisdom asserts that resource-scarce states have the strongest interest in securing control over resources. Counterintuitively, however, in Perils of Plenty, Jonathan N. Markowitz finds that the opposite is true. In actuality, what states make influences what they want to take. Specifically, Markowitz argues that the more economically dependent states are on resource extraction rents for income, the stronger their preferences will be to secure control over resources. He tests the theory with a set of case studies that analyze how states reacted to the 2007 exogenous climate shock that exposed energy resources in the Arctic. Given the dangerous potential for conflict escalation in the Middle East and the South China Sea and the continued shrinkage of the polar ice cap, this book speaks to a genuinely important development in world politics that will have implications for understanding the political effects of climate change for many years to come.
Darkening Peaks
Discussing the ways that scientists have observed and modeled glaciers, this volume tells how climate change is altering their size and distribution, and looks closely at their effect on human life. Glaciers are important water and energy sources for those living in mountains and adjacent lowlands, as well as increase the hazards of flooding and landslides. In addition to investigating these issues and considering an array of possible responses, the contributors assess the cultural and spiritual impact of glacier retreat in this timely, comprehensive work on one of the most urgent and conspicuous consequences of global warming.
The Shaping of Greenland’s Resource Spaces
The book examines ideas about the making and shaping of Greenland’s society, environment, and resource spaces. It discusses how Greenland’s resources have been extracted at different points in its history, shows how acquiring knowledge of subsurface environments has been crucial for matters of securitisation, and explores how the country is being imagined as an emerging frontier with vast mineral reserves. The book delves into the history and contemporary practice of geological exploration and considers the politics and corporate activities that frame discussion about extractive industries and resource zones. It touches upon resource policies, the nature of social and environmental asses...
The Apocalyptic Dimensions of Climate Change
Climate change and the apocalypse are frequently associated in the popular imagination of the twenty-first century. This collection of essays brings together climatologists, theologians, historians, literary scholars, and philosophers to address and critically assess this association. The contributing authors are concerned, among other things, with the relation between cultural and scientific discourses on climate change; the role of apocalyptic images and narratives in representing environmental issues; and the tension between reality and fiction in apocalyptic representations of catastrophes. By focusing on how figures in fictional texts interact with their environment and deal with the consequences of climate change, this volume foregrounds the broader social and cultural function of apocalyptic narratives of climate change. By evoking a sense of collective human destiny in the face of the ultimate catastrophe, apocalyptic narratives have both cautionary and inspirational functions. Determining the extent to which such narratives square with scientific knowledge of climate change is one of the main aims of this book.
Climate Change and Energy Systems
Renewable energy sources contribute 16% of the global energy consumption and most nations are working to increase the share of renewables in their total energy budget, to reduce the dependence on fossil fuel sources. Most Nordic and Baltic countries have already surpassed the target set for EU countries by 2020, to produce 20% of energy use from renewables like hydropower, solar energy, wind power, bio-energy, ocean power and geothermal energy. This publication presents results from a comprehensive research project that investigated the effects of projected future climate change on hydropower, wind power and bioenergy in the Nordic and Baltic countries, with focus on the period 2020-2050.

Monumental Archaeology in the Mongolian Altai
The stone monuments of Mongolia’s Altai Mountains trace the web of ancient cultures across that remote land. This study breaks new ground by seeking their cultural significance from within their physical locations and viewsheds. It is the first study to join the mute stone monuments to the vivid petroglyphic rock art of that region. In that and in the examination of a monument’s individualizing details, I seek to recover the impulse of original intention, the way in which monument and location fix cultural memory, and the way in which memory finally gives way to the cultural development of myth.
