Weathering: How the earth's deep wisdom can help us endure life's storms

by Ruth Allen

Rocks and mountains have withstood aeons of life on our planet - gradually eroding, shifting, solidifying, and weathering. We might spend a little less time on earth, but humans are also weathering: evolving and changing as we're transformed by the shifting climates of our lives and experiences. So, what might these ancient natural forms have to teach us about resilience and change?In a stunning exploration of our own connection to these enduring forms, outdoor psychotherapist and geologist Ruth Allen takes us on a journey through deep time and ancient landscapes, showing how geology - which has formed the bedrock of her own adult life and approach to therapy - can offer us a new way of thinking about our own grief, change and boundaries.In a world shaken by physical, political, and medical disasters, Weathering argues for a deeper understanding of the ground beneath our feet to better serve ourselves and the world we live in.

Weathering: An Introduction to the Scientific Principles

by Will J Bland David Rolls

Our landscape is constantly changing, but before the dramatic effects of erosion and mass movement take place, more subtle forces work on the rocks, minerals and soils around us. Weathering is the initial process which exposes the top few layers of the Earth to the potential for change. This book provides an introduction to the scientific principles behind mechanical, chemical and biological weathering. Starting with a consideration of the chemical and physical properties of rocks and water, the authors proceed to an accessible explanation of the weathering processes themselves, concluding with a review of weathering rates and intensities, and a survey of the effects of weathering on the landscape. Assuming little background knowledge, the authors develop ideas from first principles to provide a straightforward introduction to weathering for students of geography, geology and earth and environmental science.

Weathering and Erosion Processes in the Natural Environment

by Virendra Bahadur Singh Sughosh Madhav Naresh Chandra Pant Ravi Shekhar

Weathering and Erosion Processes in the Natural Environment An indispensable introduction to the key environmental processes of weathering and erosion Natural and human-induced weathering processes can have a great impact on soil and groundwater quality. With climate change and other environmental challenges placing increased emphasis on these resources, it has never been more important for researchers and environmental professionals to attain detailed knowledge of weathering and erosion processes. Weathering and Erosion Processes in the Natural Environment meets this need with a rigorous, systematic overview. Beginning with a description of different forces and processes that contribute to weathering, it then discusses the different kinds of landforms that can be produced by weathering and erosion processes, as well as the potential impacts of hydrogeological processes on both surface water and groundwater. The result is a volume that balances qualitative and quantitative understanding of this crucial subject. Weathering and Erosion Processes in the Natural Environment readers will also find: Documented examples in which weathering and erosion processes have led to heavy metals and other trace elements in groundwater Detailed discussion of climate change impacts, including extreme weather events and rising carbon dioxide levels Modeling approaches throughout to enable quantitative assessment and predictions of future impact Weathering and Erosion Processes in the Natural Environment is ideal for researchers and advanced students in geology, geochemistry, hydrogeochemistry and environmental science, as well as professionals dealing with water and soil management.

Weathering and the Riverine Denudation of Continents

by Pedro José Depetris Andrea Inés Pasquini Karina Leticia Lecomte

In this monograph the authors present an overview of the state-of-the-art and use examples or case histories to illustrate the combined role of rock decay and rivers on continental denudation. The Earth's surface dynamics would not be conceivable without the fundamental component of rock weathering and the subsequent transport of solid debris and dissolved components to the coastal ocean through riverine drainage pathways. In other words, continental wear away is highly dependent on the mechanisms that control mineral decay. Moreover, besides the significant role played by rivers in shaping the Earth's outer skin, there is the important function that rivers perform in all geochemical cycles, mediating between the lithosphere, the hydrosphere, the biosphere and the hydrosphere. Drainage basins and the weathering of rocks that occur therein may be significant sources (or sinks) of carbon dioxide and, hence, play a significant role in affecting the Earth's climate.

Weather affects us almost every day. When it's raining, we can't play outside. Sometimes weather is even more important. Sometimes weather shapes history.

Weaving a National Map: Review of the U.S. Geological Survey Concept of The National Map

by Committee to Review the U.S. Geological Survey Concept of The National Map

Weaving a National Map draws on contributions to a September 2002 workshop and the U.S. Geological Survey's (USGS) "vision" document for The National Map, envisioned by the USGS as a database providing public domain core geographic data about the United States and its territories that other agencies can extend, enhance, and reference as they concentrate on maintaining other data that are unique to their needs. The demand for up-to-date information in real time for public welfare and safety informs this need to update an aging paper map series that is, on average, 23 years old. The NRC report describes how "The National Map initiative would gain from improved definition so that the unprecedented number of partners needed for success will become energized to participate. The challenges faced by USGS in implementing "The National Map are more organizational than technical. To succeed, the USGS will need to continue to learn from challenges encountered in its ongoing pilot studies as well as from other federal-led programs that have partnered with multiple sectors.

Weeds of the Pacific Northwest: 368 Unwanted Plants and How to Control Them

by Sami Gray Mark Turner

A comprehensive guide to the most common weeds of the Pacific Northwest, with essential information on their management and eradication Weeds are everywhere. They crowd out valuable agricultural crops, compete with the tomatoes and beans in your vegetable garden, spread rampantly along roadsides, and pop up from the tiniest cracks in sidewalks. In order to manage them, we must first learn how to identify them. Weeds of the Pacific Northwest is a guide to identifying, controlling, and eradicating over 300 species of weeds that gardeners and homeowners are likely to encounter in Northern California, Oregon, Washington, and British Columbia. Though they can all cause trouble, each weed is different. The hundreds of user-friendly photographs and detailed descriptions of each species here ensure that you can spot and treat any weed in your path. As the experts behind this book demonstrate, some plants can be killed by eating them, some by digging, some by smothering, and some only by the judicious application of chemical herbicides—and it is very important for you and your neighbors to know and understand the differences.

A Week on the Concord and Merrimack Rivers (Dover Thrift Editions)

by Henry David Thoreau

Based on an 1839 boat trip Thoreau took with his brother from Concord, Massachusetts, to Concord, New Hampshire, and back, this classic of American literature is not only a vivid narrative of that journey, it is also a collection of thought-provoking observations on such diverse topics as poetry, literature and philosophy, Native American and Puritan histories of New England, friendship, sacred Eastern writings, traditional Christianity, and much more.Written, like Walden, while Thoreau lived at Walden Pond, and published in 1849, A Week (his first book) shares many themes with Walden, published in 1854. Both dramatize the process of self-renewal in nature and resolutely rail against the official culture and politics of the "trivial Nineteenth Century." Blending keen observation with a wealth of perceptive and informed reflections, Thoreau develops a continuous and lyrical dialogue between the past and present, as particular scenes on shore trigger reflections on the region's history and legends.Originally conceived as a travel book, A Week eventually became much more -- one of the most intellectually ambitious works of 19th-century America, and a requiem for Thoreau's brother John, who died from a sudden illness in 1842.Of Thoreau and this work, Ralph Waldo Emerson said, "H. D. Thoreau is a great man in Concord, a man of original genius and character. . . . I think it [A Week. . .] is a book of wonderful merit, which is to go far and last long."

Wege aus der Klimakatastrophe: Wie eine nachhaltige Energie- und Klimapolitik gelingt

by Lars Jaeger

Überschwemmungen, Artensterben, Völkerwanderungen, Dürren, Supertornados - der Klimawandel ist keine am Horizont drohende Gefahr mehr, sondern längst in unserem Alltag angekommen. Die Lage ist sehr ernst, aber wir haben durchaus Konzepte, den verheerenden Klimatrend aufzuhalten und umzukehren.Alle durch den Menschen erzeugten klimarelevanten Einflüsse lassen sich auf einen einzigen Faktor zurückführen: Energie. Wer die aktuelle Klimadynamik stoppen und sogar umkehren will, muss daher auch auf die drei zentralen Fragen zur Energie und dem Klima eine Antwort finden: Wie genau beeinflusst unsere bestehende Art des Energieverbrauchs das Klima? Welche Möglichkeiten haben wir, Energie ohne negative Klimaeffekte zu erzeugen? Welche technologischen Fortschritte werden uns dabei in der Zukunft konkret helfen?Lars Jaeger gibt einen Ausblick auf eine mögliche klimafreundliche Wirtschaft der Zukunft, beschreibt, wie eine ökologische Gesellschaft funktionieren kann und wie lokale Energiekonzepte weltweiten Erfolg haben können. Er kommt dabei mit einer klaren und optimistischen Botschaft: Wir verfügen schon heute über die technischen Möglichkeiten (und in der Zukunft umso mehr), um den verheerenden Klimatrend ohne signifikante Wohlstandsbeschränkung umzukehren. Die Hindernisse liegen vor allem in ökonomischen und politischen „Sachzwängen“ und partikulären wirtschaftlichen Interessenskonflikten. Diese zu überwinden, darum geht es in der zukünftigen Energiepolitik.

Wege zur Dorferneuerung: praktisches Fachwissen zur Bildung von Agro-Energiewirtschaften (SDG - Forschung, Konzepte, Lösungsansätze zur Nachhaltigkeit)

by Bernhard Adler Martin Dykstra Michael Winterstein

Vorliegendes Buch ist für Landwirte und die Bevölkerung des ländlichen Raumes konzipiert. Die Landwirte bekommen derzeit für die landwirtschaftlichen Produkte nicht den preislichen Gegenwert für ihre geleistete Arbeit. Die Bevölkerung im ländlichen Raum leidet unter der Abwanderung junger Leute und dem Zusammenbruch der Infrastrukturen. Beide Gruppen können durch eigenständiges Handeln diese Situation selbstständig und nachhaltig verbessern, denn die Ackerfläche bietet das Potenzial für zukünftige neue Produkte für die Energieversorgung. Dazu offeriert das Buch Strategien, Nahrungsmittel und Energien in Agro-Energiekomplexen zu gewinnen. Hierfür werden Synergismen bei der Produktion in der Pflanzen- und Energieproduktion auch unter dem Aspekt eines klimabedingten, temporären Wasser­mangels diskutiert sowie die Vorteile des Klarwassereinsatzes zur Bewässerung der Ackerböden. Nicht unerheblich scheint auch die Nutzung von Phosphat- und Ammoniumionen als Vollwertdüngemittel aus dem Abwasserrecycling. Beide obengenannten Zielgruppen erreichen eine spürbare Verbesserung ihrer Lebensverhältnisse durch die Bildung von Anbau- und Nutzergemeinschaften.

The Weierstrass Elliptic Function and Applications in Classical and Quantum Mechanics: A Primer for Advanced Undergraduates (SpringerBriefs in Physics)

by Georgios Pastras

The field of elliptic functions, apart from its own mathematical beauty, has many applications in physics in a variety of topics, such as string theory or integrable systems. This book, which focuses on the Weierstrass theory of elliptic functions, aims at senior undergraduate and junior graduate students in physics or applied mathematics. Supplemented by problems and solutions, it provides a fast, but thorough introduction to the mathematical theory and presents some important applications in classical and quantum mechanics. Elementary applications, such as the simple pendulum, help the readers develop physical intuition on the behavior of the Weierstrass elliptic and related functions, whereas more Interesting and advanced examples, like the n=1 Lamé problem-a periodic potential with an exactly solvable band structure, are also presented.

The Weierstrass Sigma Function in Higher Genus and Applications to Integrable Equations (Springer Monographs in Mathematics)

by Shigeki Matsutani

This book’s area is special functions of one or several complex variables. Special functions have been applied to dynamics and physics. Special functions such as elliptic or automorphic functions have an algebro-geometric nature. These attributes permeate the book. The “Kleinian sigma function”, or “higher-genus Weierstrass sigma function” generalizes the elliptic sigma function. It appears for the first time in the work of Weierstrass. Klein gave an explicit definition for hyperelliptic or genus-three curves, as a modular invariant analogue of the Riemann theta function on the Jacobian (the two functions are equivalent). H.F. Baker later used generalized Legendre relations for meromorphic differentials, and brought out the two principles of the theory: on the one hand, sigma uniformizes the Jacobian so that its (logarithmic) derivatives in one direction generate the field of meromorphic functions on the Jacobian, therefore algebraic relations among them generate the ideal of the Jacobian as a projective variety; on the other hand, a set of nonlinear PDEs (which turns out to include the “integrable hierarchies” of KdV type), characterize sigma. We follow Baker’s approach. There is no book where the theory of the sigma function is taken from its origins up to the latest most general results achieved, which cover large classes of curves. The authors propose to produce such a book, and cover applications to integrable PDEs, and the inclusion of related al functions, which have not yet received comparable attention but have applications to defining specific subvarieties of the degenerating family of curves. One reason for the attention given to sigma is its relationship to Sato's tau function and the heat equations for deformation from monomial curves. The book is based on classical literature and contemporary research, in particular our contribution which covers a class of curves whose sigma had not been found explicitly before.

The Weight of Nature: How a Changing Climate Changes Our Brains

by Clayton Page Aldern

A New York Times Editors' ChoiceA Next Big Idea Club and Sierra Magazine Must-Read BookA Behavioral Scientist&’s Summer Book List PickA Financial Times Best Summer BookA deeply reported, eye-opening book about climate change, our brains, and the weight of nature on us all. The march of climate change is stunning and vicious, with rising seas, extreme weather, and oppressive heat blanketing the globe. But its effects on our very brains constitute a public-health crisis that has gone largely unreported. Based on seven years of research, this book by the award-winning journalist and trained neuroscientist Clayton Page Aldern, synthesizes the emerging neuroscience, psychology, and behavioral economics of global warming and brain health. A masterpiece of literary journalism, this book shows readers how a changing environment is changing us today, from the inside out. Aldern calls it the weight of nature. Hotter temperatures make it harder to think clearly and problem-solve. They increase the chance of impulsive violence. Immigration judges are more likely to reject asylum applications on hotter days. Umpires, to miss calls. Air pollution, heatwaves, and hurricanes can warp and wear on memory, language, and sensory systems; wildfires seed PTSD. And climate-fueled ecosystem changes extend the reach of brain-disease carriers like mosquitos, brain-eating amoebas, and the bats that brought us the mental fog of long COVID. How we feel about climate change matters deeply; but this is a book about much more than climate anxiety. As Aldern richly details, it is about the profound, direct action of global warming on our brains and behavior—and the most startling portrait yet of unforeseen environmental influences on our minds. From farms in the San Joaquin Valley and public schools across the United States to communities in Norway&’s Arctic, the Micronesian islands, and the French Alps, this book is an unprecedented portrait of a global crisis we thought we understood.

Weird Worlds

by David A. Seargent

"Weird Worlds" is the third book in David Seargent's "Weird" series. This book assumes a basic level of astronomical understanding and concentrates on the "odd and interesting" aspects of planetary bodies, including asteroids and moons. From our viewpoint here on Earth, this work features the most unusual features of these worlds and the ways in which they appear "weird" to us. Within our own Solar System, odd facts such as the apparent reversal of the Sun in the skies of Mercury, CO2-driven fountains of dust on Mars, possible liquid water (and perhaps primitive life!) deep within the dwarf planet Ceres, and a variety of odd facts about the planetary moons are all discussed. A special chapter is devoted to Saturn's giant moon Titan, and its methane-based weather system and "hydrological" cycle. This chapter also includes recent speculation on the possibility of methane-based organisms and the form that these might take, if they really do exist. Beyond our Solar System, the book looks at the range of worlds discovered and hypothesized. In "Weird Worlds," the author discusses planets where temperatures are so high that it rains molten iron, and others so cold that liquid methane floods across plains of ice! Worlds are described where the lightest element acts like a metal and where winds blow at thousands of miles per hour - as well as possible planets whose orbits are essentially parabolic. In keeping with previous titles in David Seargent's "Weird" series, "Weird Worlds" contains several projects that astronomers of all levels can undertake.
