A co-winner of the 2007 Nobel Peace Prize offers a clear-eyed explanation of the planet’s imperiled ice. Much has been written about global warming, but the crucial relationship between people and ice has received little focus—until now. As one of the world’s leading experts on climate change, Henry Pollack provides an accessible, comprehensive survey of ice as a force of nature, and the potential consequences as we face the possibility of a world without ice. A World Without Ice traces the effect of mountain glaciers on supplies of drinking water and agricultural irrigation, as well as the current results of melting permafrost and shrinking Arctic sea ice—a situation that has degraded the habitat of numerous animals and sparked an international race for seabed oil and minerals. Catastrophic possibilities loom, including rising sea levels and subsequent flooding of lowlying regions worldwide, and the ultimate displacement of millions of coastal residents. A World Without Ice answers our most urgent questions about this pending crisis, laying out the necessary steps for managing the unavoidable and avoiding the unmanageable.

3 new biota and extinction of others, and extensive soil erosion reaching almost catastrophic proportions have led to desertification of many upland areas and abandonment by local populations. The role of climatic change as opposed to deforestation and sheep grazing in creating these new environments has proved a further issue of great controversy. While our understanding of historic environmental changes remains inadequate, our knowledge of processes that are modifying the present-day landscape is also sparse and selective. Little is known of active periglacial processes, slope instabilities, and rates of soil erosion by slope wash and aeolian transport. Coastal processes of erosion and beach formation have been studied only locally. Most of our information on recent or active processes comprises records of glacier fluctuations, volcanic eruptions and jOkulhlaup events, but sti11little is known of the mechanisms and processes of landscape change effected by these events. This volume of papers, based on a conference sponsored by the Quaternary Research Association and the Geologists Association and held at the University of Aberdeen in April 1989, addresses many of these crucial uncertainties regarding environmental changes in Iceland from the Lateglacial onwards. The papers make a major contribution to dispelling many earlier uncertainties and clarifying areas of controversy. Many of the papers challenge traditional and poorly supported ideas, replacing them with hypotheses based on new data and new insights derived from the expansion of wider scientific expertise and theory. The volume focuses on three major areas of research in particular.

In this new volume in the World Soil series, the various types of Icelandic soils, their different characteristics, their formation, degradation and erosion are reviewed. At the same time, the book also deals with the agriculture and land use in general to give a complete view of Icelandic soils. The first part details the natural parameters such as the climate and the geography of Iceland. It also explains Icelandic geology, which is the major parameter controlling the soil formation in this country. The author describes the formation of Iceland, the main volcanic systems, central volcanoes, tephra production and its influence on the soils. Explanations on rocks, glaciers, rivers and other main geologic features are also given. The book continues with a description of the Icelandic geomorphology, giving insights on the main surface types, frost, cryoturbation and other cryogenic features. Then it details the different types of soils, their formation and main features, comparing the Icelandic soils to other soils elsewhere in the world. Erosion and land degradation are then reviewed, including the exceptionally active wind erosion and dust production. Finally, it gives an insight on land use, agriculture and vegetation types. All this accompanied by the most amazing photos to illustrate the great diversity of Icelandic Soil.

The 2020 edition of The State of World Fisheries and Aquaculture has a particular focus on sustainability. This reflects a number of specific considerations. First, 2020 marks the twenty-fifth anniversary of the Code of Conduct for Responsible Fisheries (the Code). Second, several Sustainable Development Goal indicators mature in 2020. Third, FAO hosted the International Symposium on Fisheries Sustainability in late 2019, and fourth, 2020 sees the finalization of specific FAO guidelines on sustainable aquaculture growth, and on social sustainability along value chains. While Part 1 retains the format of previous editions, the structure of the rest of the publication has been revised. Part 2 opens with a special section marking the twenty fifth anniversary of the Code. It also focuses on issues coming to the fore, in particular, those related to Sustainable Development Goal 14 and its indicators for which FAO is the “custodian” agency. In addition, Part 2 covers various aspects of fisheries and aquaculture sustainability. The topics discussed range widely, from data and information systems to ocean pollution, product legality, user rights and climate change adaptation. Part 3 now forms the final part of the publication, covering projections and emerging issues such as new technologies and aquaculture biosecurity. It concludes by outlining steps towards a new vision for capture fisheries. The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to-date information to a wide audience – policymakers, managers, scientists, stakeholders and indeed everyone interested in the fisheries and aquaculture sector.

The book that will make you understand what our future holds for us, if we don't act immediately.

This book was written by undergraduate students at The Ohio State University (OSU) who were enrolled in the class Introduction to Environmental Science. The chapters describe some of Earth's major environmental challenges and discuss ways that humans are using cutting-edge science and engineering to provide sustainable solutions to these problems. Topics are as diverse as the students, who represent virtually every department, school and college at OSU. The environmental issue that is described in each chapter is particularly important to the author, who hopes that their story will serve as inspiration to protect Earth for all life.

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.
