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.

Environmental factors in the Middle East and North Africa (MENA) have played a crucial role in the historical and social development of the region. The book delves into a broad set of historical literature from the past 15,000 years that neglected to consider environmental factors to their full effect. Beyond the broad historic analysis, the chapters derive conclusions for today’s debate on whether climate change leads to more social conflict and violence. Introducing a theoretical framework focused on adaptive cycling, this book probes and refines the role of climate in ancient and modern political-economic systems in the MENA region. It also underscores just how bad the 21st-century environment may become thanks to global warming. While the MENA region may not survive the latest onslaught of deteriorating climate, there is also some interest in how a region that once led the world in introducing all sorts of innovations thousands of years ago has evolved into a contemporary setting characterized by traditional conservatism, poverty, and incessant strife. Emphasizing regional dynamics, the book's central question deals with the role of climate change in the rise and decline of the MENA region. The book will be a key resource to students and readers interested in global warming, including academics and policymakers.

This unique book includes 250 maps related to various factors of meteorology and climate and their effects on the African continent. It provides detailed coverage of fundamentally important issues concerning African meterology, climatology, tropical circulation, rainfall, drought and climate change.

The Second International Symposium on the East African Lakes was held from 10-15 January 2000 at Club Makokola on the southern shore of Lake Malawi. The symposium was organized by the International Decade for the East African Lakes (IDEAL), a research consortium of African, European and North American scientists interested in promoting the investigations of African Great Lakes as archives of environmental and climatic dynamics. Over one hundred African, European and North American scientists with special expertise in the tropical lakes participated in the symposium which featured compelling presentations on the limnology, climatology, palaeoclimatology and biodiversity of the East African Lakes. It is their papers that comprise this book. The large lakes of East Africa are important natural resources that are heavily utilized by their bordering countries for transportation, water supply, fisheries, waste disposal, recreation and tourism. The lakes are unique in many ways: they are sensitive to climatic change and their circulation dynamics, water-column chemistry and biological complexity differ significantly from large lakes at higher latitudes; they have long, continuous, high resolution records of past climatic change; and they have rich and diverse populations of endemic organisms. These unique properties and the significance of the palaeolimnological records demand and attract research interest from around the world.
