Content: Intended as a text for upper-division undergraduates, graduate students and as a potential reference, this broad-scoped resource is extensive in its educational appeal by providing a new concept-based organization with end-of-chapter literature references, self-quizzes, and illustration interpretation. The concept-based, pedagogical approach, in contrast to the classic discipline-based approach, was specifically chosen to make the teaching and learning of plant anatomy more accessible for students. In addition, for instructors whose backgrounds may not primarily be plant anatomy, the features noted above are designed to provide sufficient reference material for organization and class presentation. This text is unique in the extensive use of over 1150 high-resolution color micrographs, color diagrams and scanning electron micrographs. Another feature is frequent side-boxes that highlight the relationship of plant anatomy to specialized investigations in plant molecular biology, classical investigations, functional activities, and research in forestry, environmental studies and genetics, as well as other fields. Each of the 19 richly-illustrated chapters has an abstract, a list of keywords, an introduction, a text body consisting of 10 to 20 concept-based sections, and a list of references and additional readings. At the end of each chapter, the instructor and student will find a section-by-section concept review, concept connections, concept assessment (10 multiple-choice questions), and concept applications. Answers to the assessment material are found in an appendix. An index and a glossary with over 700 defined terms complete the volume

Content: It is not so long ago (a mere 17,000 years – a blink in geologic time) that vast areas of the Northern Hemisphere were covered with ice sheets up to two miles thick, lowering the oceans by more than 120 m. By 11,000 years ago, most of the ice was gone. Evidence from polar ice cores and ocean sediments show that Ice Ages were persistent and recurrent over the past 800,000 years. The data suggests that Ice Ages were the normal state, and were temporarily interrupted by interglacial warm periods about nine times during this period. Quasi-periodic variations in the Earth cause the solar input to high northern latitudes to vary with time over thousands of years. The widely accepted Milankovitch theory implies that the interglacial warm periods are associated with high solar input to high northern latitudes. However, many periods of high solar input to high northern latitudes occur during Ice Ages while the ice sheets remain. The data also indicates that Ice Ages will persist regardless of solar input to high northern latitudes, until several conditions are met that are necessary to generate a termination of an Ice Age. An Ice Age will not terminate until it has been maturing for many tens of thousands of years leading to a reduction of the atmospheric CO2 concentration to less than 200 ppm. At that point, CO2 starvation coupled with lower temperatures will cause desertification of marginal regions, leading to the generation of large quantities of dust. High winds transfer this dust to the ice sheets greatly increasing their solar absorptivity, and at the next up-lobe in the solar input to high northern latitudes, solar power melts the ice sheets over about a 6,000-year interval. A warm interglacial period follows, during which dust levels drop remarkably. Slowly but surely, ice begins accumulating again at high northern latitudes and an incipient new Ice Age begins. This third edition presents data and models to support this theory

Uniform Title: La Dynamiqie du temps et du climat

Content: This is an up-to-date textbook on meteorology ond climatology with a fresh, unconventional view of the workings of the climate system, in which the author poses serious questions about the validity of certain aspects of current global warming theory. The book is divided into three parts. In Part I the author discusses general circulation in the troposphere. He argues that such circulation is driven by thermal deficil at the poles, causing Moving Polar Highs (MPHsl, which have the principal role of feeding cold air towards the tropics, This in turn causes warm air to move up towards the poles. The relief and distribution of land masses, and the Earth's rotation, control the trajectories of the MPHs, and the formation of Anticyclonic Agglutinations (AAs). The latter determine the properties of tropical circulation, the trade winds, and tropical monsoons. These discussions lead, in Part II, 10 a consideration of the dynamics of the weather through the study of perturbations, including precipitation, the role of MPHs in polar and temperate regions and at tropical margins, pulsations in the trade winds and monsoons, the concept of the meteorologIcal Equator, and tropical cyclones. Part Ill reviews the causes of climatic variations, including solar activity, variations relating to the Earth's orbit and axial inclination, volcanic eruptions and the anthropogenic greenhouse effect. The book concludes with a discussion of Palaeoclimatic variations and recent climatic evolution, including the Sahelian drought, changes in polar and alpine glaciers, and the El Niño/Southern Oscillation,

Content: This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature.

Content: The periglacial environment, Third Edition, provides an authoritative overview of the world's cold, non-glacial environments. Emphasis is placed upon the North American and Eurasian polar lowlands. Examples are also drawn from Antarctica, the Qinghai-Xizang (Tibet) Plateau, and the northern mid-latitudes. [...] The Third Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes, and landforms that typify periglacial environments. The text is divided into four parts. Part One discusses the periglacial concept and its interactions with geomorphology, geocryology and Quaternary science. It also outlines the range and variability of periglacial climates and the degree to which landscapes are in geomorphic equilibrium with prevailing periglacial conditions. Part Two describes present-day terrain that is either underlain by permafrost or experiencing intense frost action. The roles played by cryogenic weathering, ground ice, mass wasting, running water, wind action, snow and ice, and coastal processes are systematically analysed. Part Three summarizes evidence for the existence of periglacial conditions during the cold periods of the Pleistocene. Special reference is made to the mid-latitudes of Europe and North America. Part Four illustrates the geotechnical problems associated with human activity and resource development in periglacial environments, and discusses the potential impact of global climate change in the northern high latitudes.

Note: CONTENTS PREFACE ACKNOWLEDGEMENTS AN INTRODUCTORY NOTE CHAPTER 1 THE CHALLENGE Oil and gas pipelines: early development Pipelines for cold regions Pipelines and the public interest Where does the "North" begin? The freezing of soils Permafrost CHAPTER 2 THE TERRAIN IN COLD REGIONS Patterned ground Solifluction and other soil movements on slopes Ice-wedge polygons, pingoes and palsar Other ice in the ground and thermokarst The climate of the ground CHAPTER 3 A BRIEF HISTORY OF GEOTECHNICAL ACTIVITIES AND ASSOCIATED SCIENTIFIC RESEARCH IN THE NORTH The passive, or pre-technological approach Post-war Northern development and the geotechnical approach up to 1960 Pressure The scientific approach What happens when soils freeze? Conservation and concern for the natural environment CHAPTER 4 THE TRANS-ALASKA PIPELINE The first big pipeline on permafrost Permafrost and earthquakes Terrain conditions and site investigations The pipeline and hydrological conditions Solutions to the problems The completed pipeline CHAPTER 5 THE GAS PIPELINES AND THE FROST HEAVE PROBLEM The Mackenzie Valley pipeline Frost heave and the cold pipeline Origin of the heaving pressure Frost heave and the shut-off pressure Measuring the movement of water through frozen ground A difference of opinion A change of plans CHAPTER 6 THE ALASKA HIGHWAY PIPELINE The approved pipeline Some general problems applying to gas pipelines Creeping soils, rivers, and glacier-dammed lakes The Alaska Highway Pipeline and the frost heave problem Another change of plans CHAPTER 7 MORE PIPELINES, MORE SCIENCE AND MORE POLITICS Russian pipelines The Norman Wells oil pipeline Applied science carried out by a company A pipeline bent in France International science More mega projects CHAPTER 8 FREEZING GROUND, SCIENCE AND SOCIETY Pipelines in cold places: the future A new problem or an old one? A scientific challenge neglected Who is responsible? The unanswered questions Conclusion
