Download or read book Thawing Permafrost written by J. van Huissteden and published by Springer Nature. This book was released on 2020-01-01 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a cross-disciplinary overview of permafrost and the carbon cycle by providing an introduction into the geographical distribution of permafrost, with a focus on the distribution of permafrost and its soil carbon reservoirs. The chapters explain the basic physical properties and processes of permafrost soils: ice, mineral and organic components, and how these interact with climate, vegetation and geomorphological processes. In particular, the book covers the role of the large quantities of ice in many permafrost soils which are crucial to understanding carbon cycle processes. An explanation is given on how permafrost becomes loaded with ice and carbon. Gas hydrates are also introduced. Structures and processes formed by the intense freeze-thaw action in the active layer are considered (e.g. ice wedging, cryoturbation), and the processes that occur as the permafrost thaws, (pond and lake formation, erosion). The book introduces soil carbon accumulation and decomposition mechanisms and how these are modified in a permafrost environment. A separate chapter deals with deep permafrost carbon, gas reservoirs and recently discovered methane emission phenomena from regions such as Northwest Siberia and the Siberian yedoma permafrost.

This book was released on 2020-10-30 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Academies of Sciences, Engineering, and Medicine in collaboration with the InterAcademy Partnership and the European Academies Science Advisory Committee held a workshop in November 2019 to bring together researchers and public health officials from different countries and across several relevant disciplines to explore what is known, and what critical knowledge gaps remain, regarding existing and possible future risks of harmful infectious agents emerging from thawing permafrost and melting ice in the Arctic region. The workshop examined case studies such as the specific case of Arctic region anthrax outbreaks, as a known, observed risk as well as other types of human and animal microbial health risks that have been discovered in snow, ice, or permafrost environments, or that could conceivably exist. The workshop primarily addressed two sources of emerging infectious diseases in the arctic: (1) new diseases likely to emerge in the Arctic as a result of climate change (such as vector-borne diseases) and (2) ancient and endemic diseases likely to emerge in the Arctic specifically as a result of permafrost thaw. Participants also considered key research that could advance knowledge including critical tools for improving observations, and surveillance to advance understanding of these risks, and to facilitate and implement effective early warning systems. Lessons learned from efforts to address emerging or re-emerging microbial threats elsewhere in the world were also discussed. This publication summarizes the presentation and discussion of the workshop.

Available in PDF, EPUB and Kindle. Book excerpt: "In the 1990s, researchers in the Arctic noticed that floating summer sea ice had begun receding. This was accompanied by shifts in ocean circulation and unexpected changes in weather patterns throughout the world. The Arctic's perennially frozen ground, known as permafrost, was warming, and treeless tundra was being overtaken by shrubs. What was going on? Brave New Arctic is Mark Serreze's riveting firsthand account of how scientists from around the globe came together to find answers"--Publisher's description
Download or read book The Big Thaw written by Eric Scigliano and published by Braided River, the conservation. This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permafrost--dark, ice-flaked, permanently frozen ground that lies under tundra and boreal forests across our northern regions--covers more than 12 percent of the earth's land mass. It exists in places that seem otherworldly and unimaginably remote to most of us, but the changes taking place in the permafrost layer may ultimately affect the lives of every person on Earth. InThe Big Thaw, readers meet a diverse team of scientists and students who have been studying the permafrost and what lies beneath: a vast store of ancient carbon, more than four times the quantity found in all of today's forests, which is releasing carbon dioxide and methane as the permafrost melts. The release of all this carbon would alter Earth's climate forever. Braving endless hordes of mosquitoes, quicksand, and extreme temperatures, the researchers are racing against the clock to educate us all about the changes we must make in order to preserve Earth's carbon balance.
Download or read book Vanishing Ice written by Vivien Gornitz and published by Columbia University Press. This book was released on 2019-06-11 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is thawing. In summer, cruise ships sail through the once ice-clogged Northwest Passage, lakes form on top of the Greenland Ice Sheet, and polar bears swim farther and farther in search of waning ice floes. At the opposite end of the world, floating Antarctic ice shelves are shrinking. Mountain glaciers are in retreat worldwide, unleashing flash floods and avalanches. We are on thin ice—and with melting permafrost’s potential to let loose still more greenhouse gases, these changes may be just the beginning. 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 explain why the big meltdown matters to us all. Written for all readers and students interested in the science of our changing climate, Vanishing Ice is an accessible and lucid warning of the coming thaw.
Download or read book Earth Ice Bone Blood written by Charlotte Wrigley and published by U of Minnesota Press. This book was released on 2023-04-04 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring one of the greatest potential contributors to climate change—thawing permafrost—and the anxiety of extinction on an increasingly hostile planet Climate scientists point to permafrost as a “ticking time bomb” for the planet, and from the Arctic, apocalyptic narratives proliferate on the devastating effects permafrost thaw poses to human survival. In Earth, Ice, Bone, Blood, Charlotte Wrigley considers how permafrost—and its disappearance—redefines extinction to be a lack of continuity, both material and social, and something that affects not only life on earth but nonlife, too. Earth, Ice, Bone, Blood approaches the topic of thawing permafrost and the wild new economies and mitigation strategies forming in the far north through a study of the Sakha Republic, Russia’s largest region, and its capital city Yakutsk, which is the coldest city in the world and built on permafrost. Wrigley examines people who are creating commerce out of thawing permafrost, including scientists wishing to recreate the prehistoric “Mammoth steppe” ecosystem by eventually rewilding resurrected woolly mammoths, Indigenous people who forage the tundra for exposed mammoth bodies to sell their tusks, and government officials hoping to keep their city standing as the ground collapses under it. Warming begets thawing begets economic activity— and as a result, permafrost becomes discontinuous, both as land and as a social category, in ways that have implications for the entire planet. Discontinuity, Wrigley shows, eventually evolves into extinction. Offering a new way of defining extinction through the concept of “discontinuity,” Earth, Ice, Bone, Blood presents a meditative and story-focused engagement with permafrost as more than just frozen ground.

Book excerpt: From a leading journalist in Moscow and correspondent for The New Yorker, a groundbreaking portrait of modern Russia and the inner struggles of the people who sustain Vladimir Putin's rule "Unforgettable. . . . This is a book about Putin's Russia that is unlike any other." --Patrick Radden Keefe, author of Say Nothing In this rich and novelistic tour of contemporary Russia, Joshua Yaffa introduces readers to some of the country's most remarkable figures--from politicians and entrepreneurs to artists and historians--who have built their careers and constructed their identities in the shadow of the Putin system. Torn between their own ambitions and the omnipresent demands of the state, each walks an individual path of compromise. Some muster cunning and cynicism to extract all manner of benefits and privileges from those in power. Others, finding themselves to be less adept, are left broken and demoralized. What binds them together is the tangled web of dilemmas and contradictions they face. Between Two Fires chronicles the lives of a number of strivers who understand that their dreams are best--or only--realized through varying degrees of cooperation with the Russian government. With sensitivity and depth, Yaffa profiles the director of the country's main television channel, an Orthodox priest at war with the church hierarchy, a Chechen humanitarian who turns a blind eye to persecutions, and many others. The result is an intimate and probing portrait of a nation that is much discussed yet little understood. By showing how citizens shape their lives around the demands of a capricious and frequently repressive state--as often by choice as under threat of force--Yaffa offers urgent lessons about the true nature of modern authoritarianism.

Download or read book Geocryology written by Stuart A. Harris and published by CRC Press. This book was released on 2017-09-28 with total page 903 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature. Finalist of the 2019 PROSE Awards.
