Book Description
This book gives the most detailed and comprehensive insights into the morphology, morphometry and dynamics of glaciers in the Georgian Caucasus region up to date. It examines the variability of valley glaciers after the Little Ice Age maximum and identifies glacial dynamics during historical periods. The reconstruction of glaciation in the Late Pleistocene and Holocene was conducted based on long lasting detailed glacial-geomorphological observations by the author. It further analyses moraine structures, river terraces, geodynamics of the relief, and snow and firn line locations derived from field surveys in most glacier basins in the southern and northern slopes of the Georgian Caucasus. A whole set of methodological approaches was applied including remote sensing and GIS, glacio-geomorphological, cartographical, aerial image processing and petrographic methods, unveiling accurate information about glaciers difficult to access, e.g. in the Abkhazeti and Tskhinvali regions. The book provides a full database of Georgia’s modern glaciation and displays a set of compiled maps of the distribution of the Late Pleistocene glaciation of the Georgian Caucasus.

Book Description
Located at the crossroads of Western Asia and Eastern Europe, Georgia is a country of rainforests and swamps, snow and glaciers, and semi-arid plains. It has ski resorts and mineral springs, monuments and an oil pipeline. It also has one of the longest and most turbulent histories in the Christian or Near Eastern world, but no comprehensive, up-to-date account has been written about this little-known country—until now. Remedying this omission, Donald Rayfield accesses a mass of new material from recently opened archives to tell Georgia’s absorbing story. Beginning with the first intimations of the existence of Georgians in ancient Anatolia and ending with the volatile presidency of Mikheil Saakashvili, Rayfield deals with the country’s internal politics and swings between disintegration and unity, and divulges Georgia’s complex struggles with the empires that have tried to control, fragment, or even destroy it. He describes the country’s conflicts with Xenophon’s Greeks, Arabs, invading Turks, the Crusades, Genghis Khan, the Persian Empire, the Russian Empire, and Soviet totalitarianism. A wide-ranging examination of this small but colorful country, its dramatic state-building, and its tragic political mistakes, Edge of Empires draws our eyes to this often overlooked nation.

Book Description
An international team of over 150 experts provide up-to-date satellite imaging and quantitative analysis of the state and dynamics of the glaciers around the world, and they provide an in-depth review of analysis methodologies. Includes an e-published supplement. Global Land Ice Measurements from Space - Satellite Multispectral Imaging of Glaciers (GLIMS book for short) is the leading state-of-the-art technical and interpretive presentation of satellite image data and analysis of the changing state of the world's glaciers. The book is the most definitive, comprehensive product of a global glacier remote sensing consortium, Global Land Ice Measurements from Space (GLIMS, http://www.glims.org). With 33 chapters and a companion e-supplement, the world's foremost experts in satellite image analysis of glaciers analyze the current state and recent and possible future changes of glaciers across the globe and interpret these findings for policy planners. Climate change is with us for some time to come, and its impacts are being felt by the world's population. The GLIMS Book, to be released about the same time as the IPCC's 5th Assessment report on global climate warming, buttresses and adds rich details and authority to the global change community's understanding of climate change impacts on the cryosphere. This will be a definitive and technically complete reference for experts and students examining the responses of glaciers to climate change. World experts demonstrate that glaciers are changing in response to the ongoing climatic upheaval in addition to other factors that pertain to the circumstances of individual glaciers. The global mosaic of glacier changes is documented by quantitative analyses and are placed into a perspective of causative factors. Starting with a Foreword, Preface, and Introduction, the GLIMS book gives the rationale for and history of glacier monitoring and satellite data analysis. It includes a comprehensive set of six "how-to" methodology chapters, twenty-five chapters detailing regional glacier state and dynamical changes, and an in-depth summary and interpretation chapter placing the observed glacier changes into a global context of the coupled atmosphere-land-ocean system. An accompanying e-supplement will include oversize imagery and other other highly visual renderings of scientific data.

Book Description
Glaciers and ice sheets have been melting significantly during recent decades, posing environmental threats at local, regional and global scales. Changes in glaciers are one of the clearest indicators of alterations in regional climate, since they are governed by changes in accumulation (from snowfall) and ablation (by melting of ice). Glacier chan

Book Description
Toward the end of the Age of Dinosaurs, during a time known as the Late Cretaceous, a new type of giant predator appeared along the southern coasts of North America. It was a huge species of crocodylian called Deinosuchus. Neither a crocodile nor an alligator, it was an ancestor of both modern groups; it reached weights of many tons and it had some features unique to its own species. Average-sized individuals were bigger than the carnivorous dinosaurs with which they co-existed; the largest specimens were the size of a T-rex. King of the Crocodylians, the biography of these giant beasts, tells the long history of their discovery and reports on new research about their makeup. The book also deals with the ancient life and geology of the coastal areas where Deinosuchus thrived, its competitors, and its prey, which probably included carnivorous dinosaurs. There is also detailed discussion of the methods used to determine the size of these giant animals, the dating of the fossils, the nature of their living environments, and how we know who ate whom 80 million years ago.

Book Description
Iberia, Land of Glaciers: How The Mountains Were Shaped By Glaciers discusses the impact of past glaciers in the current landscape of Iberia. Currently, there are only small glaciers in the highest peaks of the Pyrenees that are the legacy of the last cold period that ended at the end of the 19th century: The Little Ice Age. However, an accurate observation of the landscape of the highest peaks and adjacent valleys of the Iberian Peninsula reveals a past shaped by the successive passage of glaciers with hundreds of meters of ice, similar to what happens today in the Alps or Patagonia.Iberian glaciation has resulted in ice expansion through valleys that are now used by the road network and where important populations settle; in addition, large accumulations of sediments deposited by those glaciers are still unstable today and can trigger risks for mountain populations. Iberia, Land of Glaciers presents the impact of the glaciers in the landscape of mountains following a more educational perspective with examples of 21 Iberian massifs written by specialists from each of the areas. - Assesses present-day Iberian Peninsula landscape trends by understanding the past behavior of glaciers - Includes the latest findings of all the major Iberian mountains in a single book - Includes quality, color figures to enhance understanding of glacier formations - Provides a more educational and pedagogical perspective on glacial processes to reach an audience beyond academia

Book Description
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.
