Book Description
Development of reliable source emission inventories is needed to advance the understanding of the origin of Arctic haze using chemical transport modeling. This paper develops a regional anthropogenic black carbon (BC) emission inventory for the Russian Federation, the largest country by land area in the Arctic Council. Activity data from combination of local Russia information and international resources, emission factors based on either Russian documents or adjusted values for local conditions, and other emission source data are used to approximate the BC emissions. Emissions are gridded at a resolution of 0.1° × 0.1° and developed into a monthly temporal profile. Total anthropogenic BC emission of Russia in 2010 is estimated to be around 224 Gg. Gas flaring, a commonly ignored black carbon source, contributes a significant fraction of 36.2% to Russia's total anthropogenic BC emissions. Other sectors, i.e., residential, transportation, industry, and power plants, contribute 25.0%, 20.3%, 13.1%, and 5.4%, respectively. Three major BC hot spot regions are identified: the European part of Russia, the southern central part of Russia where human population densities are relatively high, and the Urals Federal District where Russia's major oil and gas fields are located but with sparse human population. BC simulations are conducted using the hemispheric version of Community Multi-scale Air Quality Model with emission inputs from a global emission database EDGAR (Emissions Database for Global Atmospheric Research)-HTAPv2 (Hemispheric Transport of Air Pollution) and EDGAR-HTAPv2 with its Russian part replaced by the newly developed Russian BC emissions, respectively. The simulation using the new Russian BC emission inventory could improve 30-65% of absorption aerosol optical depth measured at the AERONET sites in Russia throughout the whole year as compared to that using the default HTAPv2 emissions. At the four ground monitoring sites (Zeppelin, Barrow, Alert, and Tiksi) in the Arctic Circle, surface BC simulations are improved the most during the Arctic haze periods (October-March). The poor performance of Arctic BC simulations in previous studies may be partly ascribed to the Russian BC emissions built on out-of-date and/or missing information, which could result in biases to both emission rates and the spatial distribution of emissions. Finally, this study highlights that the impact of Russian emissions on the Arctic haze has likely been underestimated, and its role in the Arctic climate system needs to be reassessed. The Russian black carbon emission source data generated in this study can be obtained via http://abci.ornl.gov/download.shtml or http://acs.engr.utk.edu/Data.php.

Book Description
Wildland fires are occurring more frequently and affecting more of Earth's surface than ever before. These fires affect the properties of soils and the processes by which they form, but the nature of these impacts has not been well understood. Given that healthy soil is necessary to sustain biodiversity, ecosystems and agriculture, the impact of fire on soil is a vital field of research. Fire Effects on Soil Properties brings together current research on the effects of fire on the physical, biological and chemical properties of soil. Written by over 60 international experts in the field, it includes examples from fire-prone areas across the world, dealing with ash, meso and macrofauna, smouldering fires, recurrent fires and management of fire-affected soils. It also describes current best practice methodologies for research and monitoring of fire effects and new methodologies for future research. This is the first time information on this topic has been presented in a single volume and the book will be an important reference for students, practitioners, managers and academics interested in the effects of fire on ecosystems, including soil scientists, geologists, forestry researchers and environmentalists.

Book Description
The first evidence on the adverse effects of organic pollutants on Arctic ecosystems was provided by international research initiatives more than 30 years ago. Today, the indigenous people of the North are considered to be affected by exposure to persistent organic pollutants (POPs) and metals through their traditional marine food sources. The occurrence of pollutants of emerging concern in remote Polar environments is considered an essential criterion for prioritising this (largely neglected) type of contamination in national, international and global regulation schemes. Initiated during the first international Polar Years (IPY 2007-2009) and continued afterwards, 11 representative initiatives and projects are summarised as chapters in this book, which highlights today’s interdisciplinary research on POPs in the Polar environment. The individual chapters describe in detail the consequences, priorities and perspectives of international research on POPs (legacy and emerging xenobiotics), its implications for regulations and scientific priorities including societal and cultural developments in the Arctic, as well as conservation priorities in Antarctica. This book is intended for all readers interested in learning more about modern research on environmental pollutants in the Polar environments (with a strong focus on Arctic environments). The impacts of pollution and climate change on Polar regions and the world as a whole will continue to be felt for many years to come. Sound science is, thus, vital in order to underpin actions that need to be taken at the global, regional and local levels. This book contributes to this highly relevant, interdisciplinary environmental scientific endeavour.

Book Description
The concept of carbonaceous aerosol has only recently emerged from atmospheric pollution studies; even standard nomenclature and terminology are still unsettled. This monograph is the first to offer comprehensive coverage of the nature and atmospheric role of carbonaceous aerosol particles. Atmospheric chemists, physicists, meteorologists, and modellers will find this a thought-inspiring and sometimes provocative overview of all global phenomena affected by or related to carbonaceous aerosol.

Book Description
The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species - these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news. Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world, kindling intense debates. The reason is clear. The Anthropocene represents far more than just another interval of geologic time. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised. This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: the nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? Erle Ellis considers the many ways that the Anthropocene's "evolving paradigm" is reshaping the sciences, stimulating the humanities, and foregrounding the politics of life on a planet transformed by humans. The Anthropocene remains a work in progress. Is this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption? Ellis offers an insightful discussion of our role in shaping the planet, and how this will influence our future on many fronts. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Description
#1 NEW YORK TIMES BEST SELLER • In this urgent, authoritative book, Bill Gates sets out a wide-ranging, practical—and accessible—plan for how the world can get to zero greenhouse gas emissions in time to avoid a climate catastrophe. Bill Gates has spent a decade investigating the causes and effects of climate change. With the help of experts in the fields of physics, chemistry, biology, engineering, political science, and finance, he has focused on what must be done in order to stop the planet's slide to certain environmental disaster. In this book, he not only explains why we need to work toward net-zero emissions of greenhouse gases, but also details what we need to do to achieve this profoundly important goal. He gives us a clear-eyed description of the challenges we face. Drawing on his understanding of innovation and what it takes to get new ideas into the market, he describes the areas in which technology is already helping to reduce emissions, where and how the current technology can be made to function more effectively, where breakthrough technologies are needed, and who is working on these essential innovations. Finally, he lays out a concrete, practical plan for achieving the goal of zero emissions—suggesting not only policies that governments should adopt, but what we as individuals can do to keep our government, our employers, and ourselves accountable in this crucial enterprise. As Bill Gates makes clear, achieving zero emissions will not be simple or easy to do, but if we follow the plan he sets out here, it is a goal firmly within our reach.

Book Description
This report explores the potential for mitigating the impacts of climate change by improved management and protection of marine ecosystems and especially the vegetated coastal habitat, or blue carbon sinks. The objective of this report is to highlight the critical role of the oceans and ocean ecosystems in maintaining our climate and in assisting policy makers to mainstream an oceans agenda into national and international climate change initiatives. While emissions' reductions are currently at the centre of the climate change discussions, the critical role of the oceans and ocean ecosystems has been vastly overlooked.

Book Description
Blending close readings of literature, films, and other artworks with analysis of texts of political philosophy, science, and social theory, Mieka Erley offers an interdisciplinary perspective on attitudes to soil in Russia and the Soviet Union from the early nineteenth to the mid-twentieth century. As Erley shows in On Russian Soil, the earth has inspired utopian dreams, reactionary ideologies, social theories, and durable myths about the relationship between nation and nature. In this period of modernization, soil was understood as the collective body of the nation, sitting at the crux of all economic and social problems. The "soil question" was debated by nationalists and radical materialists, Slavophiles and Westernizers, poets and scientists. On Russian Soil highlights a selection of key myths at the intersection of cultural and material history that show how soil served as a natural, national, and symbolic resource from Fedor Dostoevsky's native soil movement to Nikita Khrushchev's Virgin Lands campaign at the Soviet periphery in the 1960s. Providing an original contribution to ecocriticism and environmental humanities, Erley expands our understanding of how cultural processes write nature and how nature inspires culture. On Russian Soil brings Slavic studies into new conversations in the environmental humanities, generating fresh interpretations of literary and cultural movements and innovative readings of major writers.

Book Description
A Brookings Institution Press and Chatham House publication The Russian annexation of Crimea was one of the great strategic shocks of the past twenty-five years. For many in the West, Moscow's actions in early 2014 marked the end of illusions about cooperation, and the return to geopolitical and ideological confrontation. Russia, for so long a peripheral presence, had become the central actor in a new global drama. In this groundbreaking book, renowned scholar Bobo Lo analyzes the broader context of the crisis by examining the interplay between Russian foreign policy and an increasingly anarchic international environment. He argues that Moscow's approach to regional and global affairs reflects the tension between two very different worlds—the perceptual and the actual. The Kremlin highlights the decline of the West, a resurgent Russia, and the emergence of a new multipolar order. But this idealized view is contradicted by a world disorder that challenges core assumptions about the dominance of great powers and the utility of military might. Its lesson is that only those states that embrace change will prosper in the twenty-first century. A Russia able to redefine itself as a modern power would exert a critical influence in many areas of international politics. But a Russia that rests on an outdated sense of entitlement may end up instead as one of the principal casualties of global transformation.
