Book Description
These proceedings record the results of climate change in many areas which are hyper-arid deserts today but which, almost cyclically, at intervals of thousands or even hundreds of thousands of years, have had a much more humid climate.

Book Description
The Arabian Sea region has several features that make it the best area for studies of climate and palaeoceanographic responses to tectonic activity, most notably in the context of the South Asian monsoon and its relationship to the growth of high topography in the adjacent Himalayas and Tibet. The papers range from high resolution, holocene palaeoceanographic studies of the Pakistan margin to regional tectonic reconstructions of the ocean basin and surrounding margins throughout the Cenozoic.

Book Description
Reconstructing climatic changes in deserts and their margins at a variety of scales in space and time, this book draws upon evidence from land and sea, including desert dunes, wind-blown dust, river and lake sediments, glacial moraines, plant and animal fossils, isotope geochemistry, speleothems, soils, and prehistoric archaeology. The book summarises the Cenozoic evolution of the major deserts of the Americas, Eurasia, Africa and Australia, and the causes of historic floods and droughts. The book then considers the causes and consequences of desertification and proposes four key conditions for achieving ecologically sustainable use of natural resources in arid and semi-arid areas. Climate Change in Deserts is an invaluable reference for researchers and advanced students interested in the climate and geomorphology of deserts: geographers, geologists, ecologists, archaeologists, soil scientists, hydrologists, climatologists and natural resource managers.

Book Description
The global climate changes that led to the expansion and contraction of high latitude ice sheets during the Quaternary period were associated with equally dramatic changes in tropical environments. These included shifts in vegetation zones, changes in the hydrology and ecology of lakes and rivers, and fluctuations in the size of mountain glaciers and sandy deserts. Until recently it was thought that such changes were triggered by fluctuations in the distribution of polar ice cover. Now there is increasing recognition that the tropics themselves have acted as drivers of global climate change over a range of timescales. The aim of Quaternary Environmental Change in the Tropics is to provide a synthesis of the changes that occurred in tropical terrestrial and marine systems during the Pleistocene and Holocene, complementing data-derived reconstructions with output from state-of-the-art climate models. It is targeted at final-year undergraduate students and research specialists, but will provide an introduction to tropical Quaternary research for a variety of other readers.

Book Description
Due to political pressures, prior to the 1990s little was known about the nature of human foraging adaptations in the deserts, grasslands, and mountains of north western China during the last glacial period. Even less was known about the transition to agriculture that followed. Now open to foreign visitation, there is now an increasing understanding of the foraging strategies which led both to the development of millet agriculture and to the utilization of the extreme environments of the Tibetan Plateau. This text explores the transition from the foraging societies of the Late Paleolithic to the emergence of settled farming societies and the emergent pastoralism of the middle Neolithic striving to help answer the diverse and numerous questions of this critical transitional period. * Examines the transition from foraging societies of the Late Paleolithic to the emergence of settled farming societies and the emergent pastoralism of the middle Neolithic * Explores explanatory models for the links between climate change and cultural change that may have influenced the development of millet agriculture * Reviews the relationship between climate change and population expansions and contraditions during the late Quaternary

Book Description
This is the first comprehensive survey of all the deserts of Arabia, based largely on the author’s 50 years of experience there. The text deals with every kind of desert in the region, from vast sand seas to clay pans and stony plains to volcanic flows. Along with dune types unique to the region the author outlines climatic changes, current ecology and human influence on desertification.

Book Description
About one-third of the Earth’s land surface experiences a desert climate, and this area supports approximately 15% of the planet’s population. This percentage continues to grow, and with this growth comes the need to acquire and apply an understanding of desert geomorphology. Such an understanding is vital in managing scarce and fragile resources and in mitigating natural hazards. This authoritative reference book is comprehensive in its coverage of the geomorphology of desert environments, and is arranged thematically. It begins with an overview of global deserts, proceeds through treatments of weathering, hillslopes, rivers, piedmonts, lake basins, and aeolian surfaces, and concludes with a discussion of the role of climatic change. Written by a team of international authors, all of whom are active in the field, the chapters cover the spectrum of desert geomorphology.

Book Description
Global Environments through the Quaternary delves into the environmental changes that have taken place during the Quaternary: the two to three million years during which man has inhabited the Earth. It is essential reading for any students seeking a balanced, objective overview of this truly interdisciplinary subject.

Book Description
Our views and understanding of variations in climate, geomorphological processes and the interrelationships that exist between climatic changes and land surface changes, both now and in the past, have developed greatly over the last decade. This book aims to encapsulate some of these recent advances and focuses on the integration of research that has been conducted by geomorphologists and climatologists on linking climate and land surface changes. This book is divided into two main parts: Section A incorporates research that has concentrated on short-term variations in climate, whilst Section B looks at some of the work on long-term climate variability. The volume concludes with a summary chapter that brings together the various ideas that have been presented in this work and other recent research in this general field. This text will be of interest to upper level students of geomorphology, Quaternary studies, climatology, earth sciences, and environmental studies. It will also be of use to researchers in these fields.

Book Description
Quaternary studies provide the essential context for evaluation of what is happening with the earth's climate today, and to clarify our vulnerability to hazardous natural processes. This book covers scientific aspects of past and present climatic changes of the quaternary period focused on the Indian subcontinent via response of modern environmental conditions on climate proxies, reconstruction of paleoclimate, paleomonsoon, glacial geology, climate variabilities using dendrochronology, cave deposits including quaternary tectonics and climate change over the Himalayan region. It consists of data generated from different landforms including lakes, caves, rivers, swamps, pits, and trenches using different proxies. Aimed at researchers, graduate students, professionals in geology, geography and environmental sciences, micropaleontology, and Quaternary climate change, this book: Studies Quaternary climate using various proxies in varied environments on the Indian sub-continent Covers pertinent historical and environmental archives to understand the current climate scenario Discusses the impact of climate change on biotic and abiotic components Includes thorough review of paleoclimate change studies Devotes significant space to glacial geology and all glacial climate proxies
