Risky futures : climate, geopolitics and local realities in the uncertain circumpolar North
\"The volume examines complex intersections of environmental conditions, geopolitical tensions and local innovative reactions characterising 'the Arctic' in the early twenty-first century. What happens in the region (such as permafrost thaw or methane release) not only sweeps rapidly through local eco-systems but also has profound global implications. Bringing together a unique combination of authors who are local practitioners, indigenous scholars and international researchers, the book provides nuanced views of the social consequences of climate change and environmental risks across human and non-human realms\"-- Provided by publisher.

Polar cousins : comparing Antarctic and Arctic geostrategic futures
Geopolitics and climate change now have immediate consequences for national and international security interests across the Arctic and Antarctic. The world’s polar regions are contested and strategically central to geopolitical rivalry. At the same time, rapid political, social, and environmental change presents unprecedented challenges for governance, environmental protection, and maritime operations in the regions. With chapters that raise awareness, address challenges, and inform policy options, Polar Cousins reviews the state of strategic thinking and options on Antarctica and the Southern Oceans in light of experience in the circumpolar North. Prioritizing strategic issues, it provides an essential discussion of geostrategic thinking, strategic policy, and strategy development. Featuring contributions from international defence experts, scientists, academics, policymakers, and decisionmakers, Polar Cousins offers key insights into the challenges unique to the polar regions.

Toward an Integrated Arctic Observing Network
Observable changes with regional and global implications, such as warming temperatures and reduced sea ice, are taking place across the Arctic. However, the record of Arctic observations suffers from incomplete geographic coverage and limited duration, and measurements are not well coordinated. This makes it difficult to comprehensively describe current conditions in the Arctic, let alone understand the changes that are underway or their connections to the rest of the Earth system.
The U.S. National Science Foundation asked for guidance to help design a pan-arctic observing network. This book outlines the potential scope, composition, and implementation strategy for an arctic observing network. Such an integrated, complete, and multidisciplinary environmental observing network will improve society's understanding of and ability to respond to ongoing systemic changes in the Arctic and its capability to anticipate, predict, and respond to future change both in the Arctic and around the globe. The network would build on and enhance existing national and international efforts and deliver easily accessible, complete, reliable, timely, long-term, pan-arctic observations. Because many potential components of the network already exist or are being planned, and because of the surge of activity during the International Polar Year, there is an immediate opportunity for major progress.

Arctic doom, Arctic boom
An expert examination of the way climate change is transforming the Arctic environmentally, economically, and geopolitically, and how the challenges of that transformation should be met. A growing number of scientists estimate that there will be no summer ice in the Arctic by as soon as 2013. Are we approaching the \"End of the Arctic?\" as journalist Ed Struzik asked in 1992, or fully entering the \"Age of the Arctic,\" as Arctic expert Oran Young predicted in 1986? Arctic Doom, Arctic Boom: The Geopolitics of Climate Change in the Arctic looks at the uncertainty at the top of the world as the shrinking of the polar ice cap opens up new sea lanes and the vast hydrocarbon riches of the Arctic seafloor to commercial development and creates environmental disasters for Arctic biota and indigenous peoples. Arctic Doom, Arctic Boom explores the geopolitics of the Arctic from a historical as well as a contemporary perspective, showing how the warming of the Earth is transforming our very conception of the Arctic. In addition to addressing economic and environmental issues, the book also considers the vital strategic role of the region in our nation's defenses.

Vanishing ice : glaciers, ice sheets, and rising seas
\"The Arctic is thawing. 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 demonstrate why the big meltdown matters to us all\"-- Provided by publisher.

A history of the Arctic
Bitter cold and constant snow. Polar bears, seals, and killer whales. Victor Frankenstein chasing his monstrous creation across icy terrain in a dogsled. The arctic calls to mind a myriad different images. Consisting of the Arctic Ocean and parts of Canada, the United States, Russia, Greenland, Finland, Norway and Sweden, the arctic possesses a unique ecosystem-temperatures average negative 29 degrees Fahrenheit in winter and rarely rise above freezing in summer-and the indigenous peoples and cultures that live in the region have had to adapt to the harsh weather conditions. As global temperatures rise, the arctic is facing an environmental crisis, with melting glaciers causing grave concern around the world. But for all the renown of this frozen region, the arctic remains far from perfectly understood. In A History of the Arctic, award-winning polar historian John McCannon provides an engaging overview of the region that spans from the Stone Age to the present. McCannon discusses polar exploration and science, nation-building, diplomacy, environmental issues, and climate change, and the role indigenous populations have played in the arctic's story. Chronicling the history of each arctic nation, he details the many failed searches for a Northwest Passage and the territorial claims that hamper use of these waterways. He also explores the resources found in the arctic-oil, natural gas, minerals, fresh water, and fish-and describes the importance they hold as these resources are depleted elsewhere, as well as the challenges we face in extracting them. A timely assessment of current diplomatic and environmental realities, as well as the dire risks the region now faces, A History of the Arctic is a thoroughly engrossing book on the past-and future-of the top of the world.
