Tourism and Change in Polar Regions by C. Michael Hall,Jarkko Saarinen Pdf
The world’s polar regions are attracting more interest than ever before. Once regarded as barren, inhospitable places where only explorers go, the north and south polar regions have been transformed into high profile tourism destinations, increasingly visited by cruise ships as well as becoming accessible with direct flights. Tourism is seen as one of the few economic opportunities in these regions but at the same time the polar regions are being opened up to tourism development they are being affected by a number of new factors that are interconnected to travel and tourism. Climate change, landscape and species loss, increasing interest in energy resources and minerals, social changes in indigenous societies, and a new polar geopolitics all bring into question the sustainability of polar regions and the place of tourism within them. This timely volume provides a contemporary account of tourism and its impacts in polar regions. It explores the development and prospects of polar tourism, as well as tourism’s impacts and associated change at high latitudes from environmental, economic, social and political perspectives. It draws on cutting edge research from both the Arctic and Antarctic to provide a comparative review and illustrate the real life issues arising from tourism’s role in these regions. Integrating theory and practice the book fully evaluates varying perspectives on polar tourism and proposes actions that could be taken by local and global management to achieve a sustainable future for polar regions and development of tourism. This complete and current account of polar tourism issues is written by an international team of leading researchers in this area and will have global appeal to higher level students, researchers, academics in Tourism, Environmental Studies, Arctic/Polar Studies and conservation enthusiasts alike.

Ice in the Arctic is disappearing—and opportunity is calling. As climate change transforms the top of the world, warmer conditions are exposing a treasure trove of energy resources previously trapped in ice. The Arctic's oil, natural gas, minerals, and even wind and hydroelectric power are becoming more accessible than ever before. With untold riches hanging in the balance, the race is on to control the Arctic and its energy potential. Oil companies vie for drilling rights that go to the highest bidder. Nations around the globe—whether they're on the Arctic's doorstep or half a world away—hope to claim territory for themselves. And the indigenous peoples who have called this region home for thousands of years are determined to be on the ground floor of its development. But the Arctic's new possibilities come with grave risks. The pursuit of oil and natural gas threatens to further damage the Arctic's fragile ecosystems and accelerate global warming worldwide. International disputes over who owns which pieces of the Arctic could bring countries to the brink of war. The fate of the entire planet may hinge on how far people are willing to go to tap and control the Far North's energy resources. From oil rigs to military bases, the Arctic has never before hosted so many warring interests, and the stakes have never been so high. Join Stephanie Sammartino McPherson on a journey to the Far North to explore the energy controversies that will decide the future of the Arctic—and of the earth.

The committee recommends that the U.S. scientific community and participating agencies use this opportunity to better understand environmental change and variability in the polar regions; explore new scientific frontiers ranging from the molecular to the planetary scales; and engage the public through varied educations and outreach activities.
The Climate of the Arctic by Rajmund Przybylak Pdf
th Towards the end of the 19 century some researchers put forward the hypothesis that the Polar regions may play the key role in the shaping of the global climate. This supposition found its full confirmation in empirical and th model research conducted in the 20 century, particularly in recent decades. The intensification of the global warming after about 1975 brought into focus the physical causes of this phenomenon. The first climatic models created at that time, and the analyses of long observation series consistently showed that the Polar regions are the most sensitive to climatic changes. This aroused the interest of numerous researchers, who thought that the examination of the proc esses taking place in these regions might help to determine the mechanisms responsible for the "working" of the global climatic system. To date, a great number of publications on this issue have been published. However, as a re view of the literature shows, there is not a single monograph which comprises the basic information concerning the current state of the Arctic climate. The last study to discuss the climate of the Arctic in any depth was published in 1970 (Climates a/the Polar Regions, vol. 14, ed. S. Orvig) by the World Survey of Climatology, edited by H. E. Landsberg. This publication, however, does not provide the full climatic picture of many meteorological elements.

Frontiers in Understanding Climate Change and Polar Ecosystems by National Research Council,Division on Earth and Life Studies,Polar Research Board,Committee for the Workshop on Frontiers in Understanding Climate Change and Polar Ecosystems Pdf
The polar regions are experiencing rapid changes in climate. These changes are causing observable ecological impacts of various types and degrees of severity at all ecosystem levels, including society. Even larger changes and more significant impacts are anticipated. As species respond to changing environments over time, their interactions with the physical world and other organisms can also change. This chain of interactions can trigger cascades of impacts throughout entire ecosystems. Evaluating the interrelated physical, chemical, biological, and societal components of polar ecosystems is essential to understanding their vulnerability and resilience to climate forcing. The Polar Research Board (PRB) organized a workshop to address these issues. Experts gathered from a variety of disciplines with knowledge of both the Arctic and Antarctic regions. Participants were challenged to consider what is currently known about climate change and polar ecosystems and to identify the next big questions in the field. A set of interdisciplinary "frontier questions" emerged from the workshop discussions as important topics to be addressed in the coming decades. To begin to address these questions, workshop participants discussed the need for holistic, interdisciplinary systems approach to understanding polar ecosystem responses to climate change. As an outcome of the workshop, participants brainstormed methods and technologies that are crucial to advance the understanding of polar ecosystems and to promote the next generation of polar research. These include new and emerging technologies, sustained long-term observations, data synthesis and management, and data dissemination and outreach.
Stories of Change and Sustainability in the Arctic Regions by Rita Sørly,Tony Ghaye,Bård Kårtveit Pdf
This book presents stories of sustainability from communities in circumpolar regions as they grapple with environmental, economic and societal changes and challenges. Polar regions are changing rapidly. These changes will dramatically effect ecosystems, economy, people, communities and their interdependencies. Given this, the stories being told about lives and livelihood development are changing also. This book is the first of its kind to curate stories about opportunity and responsibility, tensions and contradictions, un/ethical action, resilience, adaptability and sustainability, all within the shifting geopolitics of the north. The book looks at change and sustainability through multidisciplinary and empirically based work, drawing on case studies from Norway, Sweden, Alaska, Canada, Finland and Northwest Russia, with a notable focus on indigenous peoples. Chapters touch on topics as wide ranging as reindeer herding, mental health, climate change, land-use conflicts and sustainable business. The volume asks whose voices are being heard, who benefits, how particular changes affect people’s sense of community and longstanding and cherished values plus livelihood practices and what are the environmental, economic and social impacts of contemporary and future oriented changes with regard to issues of sustainability? This volume will be of great interest to students and scholars of sustainability studies, sustainable development, environmental sociology, indigenous studies and environmental anthropology.
