Book Description
"The importance of the Arctic in many fields of human activity strongly increased over the past decades. The academic scientific research demonstrates a 3-fold increase in the number of journal articles dealing with "Arctic": from 1,400 in 2000 to 4,200 in 2018. This increase is not fortuitous but certainly stems from double importance of Arctic regions for humanity. The first importance is the role that the Arctic plays in the on-going environmental changes, mostly linked to climate warming and environmental pollution. Here, the first key issues are the Arctic Ocean, ice melt, permafrost thaw, greenhouse gases emission, and organic carbon mobilization from soils to rivers. From the other hand, highly fragile Arctic ecosystems and biota are strongly affected by environmental pollution, be it organic compounds or toxic metals and radionuclides. The rising concern of humanity to the key role of the Arctic in climate regulation on the planetary scale and the extreme fragility of its ecosystem, biota and native population to on-going environmental change can certainly explain an explosive interest of scientific researchers to the Arctic in connection with 'climate change'. The second big issue of the Arctic is its eminent role in problems of natural resources. The Artic shelf contains vast amount of hydrocarbons (gas and oil), whereas the terrestrial polar regions, now liberating from ice, may turn out to be highly important sites of future ore industry. The importance of possibly ice-free Arctic Ocean as future maritime shipping routes will further enhance the accessibility of natural resources in this region. Taken together, this can be the main driving factors of almost exponential increase in the interest to natural resources in the Arctic over past few years. The present book addresses a wide variety of environmental, social and economic issues of the Arctic, in response to rising interest to this region in academic science, sociology and business. The 14 chapters represent state-of-the art reviews written by the experts on problems of native communities, climate change, political issues, implementation of large-scale projects, natural resources and conservation, environmental monitoring and assessment of pollution issues"--

Book Description
Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.

Book Description
This book is a new and revised second edition of the book ‘The Climate of the Arctic’, published in 2003. It presents a comprehensive analysis of the current state of knowledge related to the climate of the Arctic, using the latest meteorological data. All meteorological elements are described in detail and an up-to-date review of the available literature for each element is given. Climatic regions are distinguished and described. The monograph also provides an account of the present state of research on climate change and variability in the Arctic for three time scales: the Holocene, the last Millennium, and the instrumental period. The book concludes with a presentation of the scenarios of the Arctic climate in the 21st century. This monograph is intended for all those with a general interest in the fields of meteorology, climatology, and with a knowledge of the application of statistics in these areas.

Book Description
The United States has enduring national and strategic interests in the polar regions, including citizens living above the Arctic circle and three year-round scientific stations in the Antarctic. Polar icebreaking ships are needed to access both regions. Over the past several decades, the U.S. government has supported a fleet of four icebreakersâ€"three multi-mission U.S. Coast Guard ships (the POLAR SEA, POLAR STAR, and HEALY) and the National Science Foundation's PALMER, which is dedicated solely to scientific research. Today, the POLAR STAR and the POLAR SEA are at the end of their service lives, and a lack of funds and no plans for an extension of the program has put U.S. icebreaking capability at risk. This report concludes that the United States should continue to support its interests in the Arctic and Antarctic for multiple missions, including maintaining leadership in polar science. The report recommends that the United States immediately program, budget, design, and construct two new polar icebreakers to be operated by the U.S. Coast Guard. The POLAR SEA should remain mission capable and the POLAR STAR should remain available for reactivation until the new polar icebreakers enter service. The U.S. Coast Guard should be provided sufficient operations and maintenance budget to support an increased, regular, and influential presence in the Arctic, with support from other agencies. The report also calls for a Presidential Decision Directive to clearly align agency responsibilities and budgetary authorities.

Book Description
Public awareness of the importance of Antarctic research, particularly in relation to global problems, has increased. The book spans a broad spectrum of Antarctic science from the "ozone hole" to microbiology to the sea ice. The main focus is on the role of Antarctica and the Southern Ocean in the world climate system, e.g. the formation of sea ice and its relevance to ocean circulation, the biological pump in relation to CO2 release. The past climate history is revealed by the analysis of ice cores and sediments. Studies of plate tectonics and fossil records reach further back in earth history. Key words in the biological chapters are krill and the rich Antarctic benthos. Finally, the potential conflict between conservationists, researchers and tourists is discussed.
