The Mackenzie Basin Impact Study is a six-year study supported by the Government of Canada's Green Plan and other sponsors to assess the potential impacts of global warming on the Mackenzie Basin region and its inhabitants. This interim report describes the study framework, structure, organization, methods and data, and identifies participants. It also discusses water, land resources, surficial geology and natural hazards, sea ice and coastal stability, terrestrial ecosystems/biomes, freshwater ecosystems, settlements, energy and mines, transportation and infrastructure, agriculture, tourism, the forest sector, Canadian defence policies and operations, and the methodology for development of climate change scenarios.
The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. Arctic Climate Impact Assessment was prepared by an international team of over 300 scientists, experts, and knowledgeable members of indigenous communities. The report has been thoroughly researched, is fully referenced, and provides the first comprehensive evaluation of arctic climate change, changes in ultraviolet radiation and their impacts for the region and for the world. It is illustrated in full color throughout. The results provided the scientific foundations for the ACIA synthesis report - Impacts of a Warming Arctic - published by Cambridge University Press in 2004.
This volume describes current understanding of the impacts that climate change and variability will have on all aspects of the Northwest Territories/Nunavut physical & biological environment and its socio-economic activities, and of existing or potential adaptation options. The initial sections review the region's socio-economic context, ecozones, and climate, and describe various scenarios of climate change as determined from global climate change models. Section D assesses impacts of and adaptation to climate change in the physical environment (hydrology, permafrost, sea ice, sea level & coastal processes, freshwater ice), in terrestrial & marine ecosystems, and in such socio-economic sectors as oil & gas, transportation, construction, tourism, forestry, and fisheries. The final section discusses opportunities for further research.
"From the pressures of development, technological advances, globalization and climate change to social and cultural life, this book attempts to define the nature of competing demands and assess their impact on the environment. These essays provide a detailed examination of ocean and coastal management in the Canadian north, exploring a wide range of issues critical to environmental stewardship, and breaking the ice to connect academics, government managers, policy-makers, aboriginal groups and industry." --Book Jacket.
Originally published in 2000, The Arctic provides a comprehensive overview of the region's rapidly changing physical and human dimensions, and demonstrates the importance of communication between natural scientists, social scientists, and local stakeholders in response to the tremendous challenges and opportunities facing the Arctic. It is an essential resource for all Arctic researchers, particularly those developing multidisciplinary projects. It provides an overview of key areas of Arctic research by renowned specialists in the field, and each chapter forms a detailed, varied and accessible account of current knowledge. Each author introduces the subject to a specialist readership, while retaining intellectual integrity and relevance for specialists. Overall, the richness of the material presented in this volume reflects the ecological and cultural diversity of this vast and environmentally critical part of the globe.
"Bosworth Creek originates at Hodgson (Jackfish) Lake (Latitude 65° 18' N Longitude 126° 41' W), Tulita District, Sahtu Settlement Area and parallels the base of Discovery Ridge before changing course to the southeast and joining the Mackenzie River (Latitude 65° 16' N Longitude 126° 51' W) within the municipal boundaries of the Town of Norman Wells. Bosworth Creek has played an important role in local history. Natural flow was impeded with the construction of a weir in 1960 approximately 250 metres from its confluence with the Mackenzie River. The pond created behind this weir supplied the oil refinery with water for stream driven electricity and drinking water for the Town of Norman Wells. The town abandoned this water source in 1991 and closure of the refinery in 1996 prompted channel flow reclamation as recommended by the Government of the Northwest Territories (GNWT). The weir was removed and natural flow restored in 2005 under Imperial Oil Resources NWT Limited's Reclamation and Restoration Plan (SRRB 2008).
