Book Description
Could a giant asteroid or comet crash into Earth and destroy life as we know it? Many astronomers who once discredited the risks are now convinced. You will be too after reading Duncan Steel's critically acclaimed examination of the evidence of Earth's encounters with killer comets and asteroids. Acclaim for Rogue Asteroids and Doomsday Comets "A chilling and utterly convincing account of a cosmic menace that must not be ignored any longer. This book is a welcome challenge to the scientific prejudice against catastrophism." --Paul Davies, author of The Mind of God "Written in clear prose for the layperson, this gripping report advocates the creation of an international search program to detect, intercept, and divert Earth-menacing asteroids and comets." --Publishers Weekly. "Steel writes clearly and ominously, and he should be listened to." --The Daily Telegraph (London) A selection of the Astronomy Book Club A Library Journal "Best Science Book of the Year" selection

Book Description
This monograph addresses the legal and policy issues relating to the commercial exploitation of natural resources in outer space. It begins by establishing the economic necessity and technical feasibility of space mining today, an estimate of the financial commitments required, followed by a risk analysis of a commercial mining venture in space, identifying the economic and legal risks. This leads to the recognition that the legal risks must be minimised to enable such projects to be financed. This is followed by a discussion of the principles of international space law, particularly dealing with state responsibility and international liability, as well as some of the issues arising from space mining activities. Much detail is devoted to the analysis of the content of the common heritage of mankind doctrine. The monograph then attempts to balance such interests in creating a legal and policy compromise to create a new regulatory regime.

Book Description
Tsunamis are underrated as major hazards, mainly due to the misconceptions that they occur infrequently and happen along some distant shoreline. However, evidence for past great tsunami has recently been discovered along apparently aseismic and protected coastlines, such as those of Australia and Western Europe. This is a comprehensive and well illustrated textbook on all aspects of tsunami. It can be used by a student or layperson to gain encyclopedic knowledge about tsunami.

Book Description
Imagining the End provides students and general readers with contextualized examples of how the apocalypse has been imagined across all mediums of American popular culture. Detailed entries analyze the development, influence, and enjoyment of end-times narratives. Imagining the End provides a contextual overview and individual description and analysis of the wide range of depictions of the end of the world that have appeared in American popular culture. American writers, filmmakers, television producers, and game developers inundated the culture with hundreds of imagined apocalyptic scenarios, influenced by the Biblical Book of Revelation, the advent of the end of the second millennium (2000 CE), or predictions of catastrophic events such as nuclear war, climate change, and the spread of AIDS. From being "raptured" to surviving the zombie apocalypse, readers and viewers have been left with an almost endless sequence of disasters to experience. Imagining the End examines this phenomenon and provides a context for understanding, and perhaps appreciating, the end of the world. This title is composed of alphabetized entries covering all topics related to the end times, covering popular culture mediums such as comic books, literature, films, and music.

Book Description
Using a broad selection of classic and current sources, The Natural History of the Earth probes selected discussions within biology, climatology, geology, and geomorphology and explores a selection of debates about Earth and life history, considering their origins and their present state-of-play. After outlining the arguments, placing them in an historical context and indicating their significance, the book goes on to deal with specific debates. In the geosphere section, topics covered include geological processes, the bombardment hypothesis, frigid climates and cataclysmic floods, and in the section concerning the biosphere, the topics covered include evolutionary patterns, mass extinctions, patterns in life’s history and life–environment connections. Written in a clear and accessible style, this volume will interest Earth and life scientists, physical geographers and any informed person fascinated by long-term Earth history. This accessible volume is illustrated throughout with over fifty informative diagrams, photographs, tables and over 700 references.
