The book offers a modern, comprehensive, and holistic view of natural gas seepage, defined as the visible or invisible flow of gaseous hydrocarbons from subsurface sources to Earth’s surface. Beginning with definitions, classifications for onshore and offshore seepage, and fundamentals on gas migration mechanisms, the book reports the latest findings for the global distribution of gas seepage and describes detection methods. Seepage implications are discussed in relation to petroleum exploration, environmental impacts (hazards, pollution, atmospheric emissions, and past climate change), emerging scientific issues (abiotic gas and methane on Mars), and the role of seeps in ancient cultures. With an updated bibliography and an integrated analysis of available data, the book offers a new fundamental awareness - gas seepage is more widespread than previously thought and influences all of Earth’s external “spheres”, including the hydrosphere, atmosphere, biosphere, and anthroposphere.
From khat to kava to ketamine, drugs are constitutive parts of cultures, identities, economies and livelihoods. This much-needed book is a clear introduction to the anthropology of drugs, providing a cutting-edge and accessible overview of the topic. The authors examine and assess the following key topics: How drugs feature in anthropology and the work of anthropologists and the general role of drugs in society Comparison between biochemical and pharmacological approaches to drugs and bio-socio-cultural models of understanding drugs Evolutionary origins of psychotropic drug sensitivity and archaeological evidence for the spread of psychoactive substances in pre-history Drugs in spiritual and...
"Methane is a powerful greenhouse gas and is estimated to be responsible for approximately one-fifth of man-made global warming. Per kilogram, it is 25 times more powerful than carbon dioxide over a 100-year time horizon -- and global warming is likely to enhance methane release from a number of sources. Current natural and man-made sources include many where methane-producing micro-organisms can thrive in anaerobic conditions, particularly ruminant livestock, rice cultivation, landfill, wastewater, wetlands and marine sediments. This timely and authoritative book provides the only comprehensive and balanced overview of our current knowledge of sources of methane and how these might be contr...
The author looks at the prospects for a transition from natural gas to low carbon gas, which could take several decades, and at how this will depend on the evolution of the fossil fuel industry. She investigates the technologies and energy systems for making the best use of renewable gas resources.
1. PURPOSE OF PRESENT BOOK During the period May 19-26, 2003 the NATO Advanced Research Workshop (ARW) “Mud volcanism, Geodynamics and Seismicity” was held in Baku. Participants coming from USA, Germany, France, Italy, Portugal, Russian Federation, Ukraine, Romania, Georgia, UK, Israel, Azerbaijan, Tunisia have discussed about different geodynamic features of mud volcanism and participated to field trips oriented to a better knowledge of mud volcanic features. The Meeting focused on many features of mud volcanism occurrence and related geodynamic topics. The purpose of present book is to collect contributions discussed during the Meeting and to fill a marked editorial gap on mud volcanis...
"Weaving together historical and ethnographic research, Catalina M. de Onâis challenges the master narratives of Puerto Rico as a tourist destination and site of 'natural' disasters. She demonstrates how fossil-fuel economies are inextricably entwined with colonial practices and policies and how local community groups in Puerto Rico have struggled against energy coloniality and energy privilege to mobilize and transform power from the ground up. This work decenters continental contexts and deconstructs damaging hierarchies that devalue and exploit disenfranchised rural, coastal communities"--

This greatly expanded and revised edition contains more than 1,000 entries, covering everything from common everyday foods to the latest in genetic research—and beyond. Each substance’s properties are objectively described based on the latest scientific evidence. Included are substances that not only claim to improve thinking and other brain functions, but those that are thought to help prevent brain damage and degeneration, prevent aging and extend the human lifespan, enhance social skills and moral behavior, induce altered states of consciousness, and improve mood, stamina, and energy.
To understand climate change today, we first need to know how Earth’s climate changed over the past 450 million years. Finding answers depends upon contributions from a wide range of sciences, not just the rock record uncovered by geologists. In Earth’s Climate Evolution, Colin Summerhayes analyzes reports and records of past climate change dating back to the late 18th century to uncover key patterns in the climate system. The book will transform debate and set the agenda for the next generation of thought about future climate change. The book takes a unique approach to the subject providing a description of the greenhouse and icehouse worlds of the past 450 million years since land plan...
