An urgent account of the explorers and scientists racing to understand the rapidly melting ice sheet in Greenland, a dramatic harbinger of climate change. As Greenland's ice melts and runs off into the sea, it not only threatens to affect hundreds of millions of people who live in coastal areas. It will also have drastic effects on ocean currents, weather systems, economies, and migration patterns

The earth’s cryosphere, which includes snow, glaciers, ice caps, ice sheets, ice shelves, sea ice, river and lake ice, and permafrost, contains about 75% of the earth’s fresh water. It exists at almost all latitudes, from the tropics to the poles, and plays a vital role in controlling the global climate system. It also provides direct visible evidence of the effect of climate change, and, therefore, requires proper understanding of its complex dynamics. This encyclopedia mainly focuses on the various aspects of snow, ice and glaciers, but also covers other cryospheric branches, and provides up-to-date information and basic concepts on relevant topics. It includes alphabetically arranged and professionally written, comprehensive and authoritative academic articles by well-known international experts in individual fields. The encyclopedia contains a broad spectrum of topics, ranging from the atmospheric processes responsible for snow formation; transformation of snow to ice and changes in their properties; classification of ice and glaciers and their worldwide distribution; glaciation and ice ages; glacier dynamics; glacier surface and subsurface characteristics; geomorphic processes and landscape formation; hydrology and sedimentary systems; permafrost degradation; hazards caused by cryospheric changes; and trends of glacier retreat on the global scale along with the impact of climate change. This book can serve as a source of reference at the undergraduate and graduate level and help to better understand snow, ice and glaciers. It will also be an indispensable tool containing specialized literature for geologists, geographers, climatologists, hydrologists, and water resources engineers; as well as for those who are engaged in the practice of agricultural and civil engineering, earth sciences, environmental sciences and engineering, ecosystem management, and other relevant subjects.

In the 1990s Richard B. Alley and his colleagues made headlines with the discovery that the last ice age came to an abrupt end over a period of only three years. In The Two-Mile Time Machine, Alley tells the fascinating history of global climate changes as revealed by reading the annual rings of ice from cores drilled in Greenland. He explains that humans have experienced an unusually temperate climate compared to the wild fluctuations that characterized most of prehistory. He warns that our comfortable environment could come to an end in a matter of years and tells us what we need to know in order to understand and perhaps overcome climate changes in the future. In a new preface, the author weighs in on whether our understanding of global climate change has altered in the years since the book was first published, what the latest research tells us, and what he is working on next.

Earth’s climate is changing. This book investigates the scientific, environmental, social, political, and economic aspects of climate change. It enables students to reach an informed opinion and encourages active engagement in finding solutions. It begins with a strong introduction to the scientific factors that drive natural and anthropogenic climate change and expands over three chapters to explore the impact of greenhouse gases on the distribution of solar energy across land, sea, ice, and air. The author examines geologically ancient climates in order to highlight possible future scenarios, and case studies from around the world highlight the impact of climate change on the physical and human environment. The final chapters investigate how society can respond to the challenges of climate change and overcome the political, social, and economic factors that are barriers to progress, focusing on the role of energy policy, fiscal policy, and risk assessment as a means to stimulate discussion about science, society, and the role of the media. Science is the foundation of any solution, but to turn this knowledge into action requires the application of a broad set of skills that are rooted in the liberal arts experience such as critical thinking, analytical thinking, problem solving, and communication. This textbook will be an essential resource for students taking courses in environmental geography, climate change, natural hazards, climatology, and meteorology.

The challenge in teaching an introductory course on sustainability is there are many ways to teach it, and many issues to cover. The United Nations Sustainable Development Goals offer a cohesive and interconnected set of topics to help address this problem – indeed the SDGs are now the guiding framework for planning and implementing sustainability through 2030. They are the focus of international development efforts, and the lingua franca of sustainability as a field of study, the international consensus on “what is sustainability?” As such, the UN SDGs present an ideal framework for an introductory level textbook because taken together, they integrate the “Three Es”—environment, economic development, and equity—that are the core definition of sustainability. This book introduces students to sustainability structured around the 17 UN SDGs. Through a global perspective, with attention given equally to how sustainability challenges the highest income countries of the Global North, as well as to the moderate- and low-income countries of the Global South, Benton-Short synthesizes basic environmental science, policy, and interdisciplinary perspectives while investigating key challenges to developing a more sustainable future through the SDG framework. Readers will easily tackle this complex set of topics through an accessible writing style, comprehensive scholarship, and diverse perspectives. Guided by a lush art program, complete with numerous maps, figures, and photos to enliven the presentation, students will develop a greater understanding of the important trends in sustainability in the twenty-first century. The broad arguments highlighted through numerous case studies and boxes prepare global citizens to grapple with the environmental, social, economic, and political challenges that face our collective future. Features of this exciting, brand-new text include: Chapter opening learning objectives to guide students’ course goals Helpful study aids such as key terms—bolded in the text and compiled both at the end of each chapter and in a comprehensive glossary End-of-chapter questions for discussion and activities to promote active learning A stunning art program, with detailed maps, figures, tables, and photos, to engage students as visual learners Critical Perspectives and Expert Voice boxes to present the diverse perspectives in sustainability Interconnections boxes to help students tie together ideas across the issues Key Terms and Concepts and Understanding the Issue boxes to go in-depth on important topics Making Progress and Solutions boxes that show students hopeful trends toward seemingly intractable problems SDGs and the Law boxes that provide a legal and governance context.
