Did the Earth once undergo a super ice age, one that froze the entire planet? A global adventure story and a fascinating account of scientist Paul Hoffman's quest to prove his maverick 'Snowball Earth' theory, this is science writing at its most gripping. In SNOWBALL EARTH, Gabrielle Walker takes us on a thrilling natural history expedition in search of supporting evidence for the audacious theory which argues that the Earth experienced a climatic cataclysm 600 million years ago that froze the entire planet from the poles to the equator. Because the global snowball happened so long ago the ice has now long gone - but it left its traces in rocks around the world and in order to see the evidence, Walker visited such places as Australia, Namibia, South Africa and Death Valley, USA. Part adventure story and part travel book, it's a tale of the ultimate human endeavour to understand our origins.
Up-and-coming rock star, Joan Devintia, has come to realize that some shadows aren't benign, some stares aren't innocent, and she is no longer safe. Tired of fearing her stalker, she goes to her manager for a solution. He hires Carmen Savedra - celebrity bodyguard and inactive duty Marine - to protect the singer from harm. In the midst of recording her pioneer album, Joan finds temptation in the form of illicit drugs and danger taking the shape of a man in a red tie. Safety comes with the sound of jingling dog tags that Carmen never takes off. Carmen's shadow is bigger and more imposing than Joan's stalker. Her stare is more meaningful. Unless Joan can face her fears off the stage - her career, her growing relationship with Carmen - her very life could end....
Leading scientists bring the controversy over Gaia up to date by exploring a broad range of recent thinking on Gaia theory.
In recent years climate change has become recognised as the foremost environmental problem of the twenty-first century. Not only will climate change potentially affect the multibillion dollar energy strategies of countries worldwide, but it also could seriously affect many species, including our own. A fascinating introduction to the subject, this textbook provides a broad review of past, present and likely future climate change from the viewpoints of biology, ecology and human ecology. It will be of interest to a wide range of people, from students in the life sciences who need a brief overview of the basics of climate science, to atmospheric science, geography, and environmental science students who need to understand the biological and human ecological implications of climate change. It will also be a valuable reference for those involved in environmental monitoring, conservation, policy-making and policy lobbying.
This book provides a comprehensive coverage of the major topicswithin undergraduate study programmes in geosciences, environmentalscience, physical geography, natural hazards and ecology. This text introduces students to the Earth's four keyinterdependent systems: the atmosphere, lithosphere, hydrosphereand biosphere, focussing on their key components, interactionsbetween them and environmental change. Topics covered include: An earth systems model; componentssystems and processes: atmospheric systems; oceanography, endogenicgeological systems and exogenic geological systems, biogeographyand, aspects of the Earth's Record. The impact of climate and environmental change is discussed in afinal chapter which draws together Earth's systems and theirevolution and looks ahead to future earth changes and environmentsand various time periods in the geological record. Throughout the book geological case studies are used in additionto the modern processes.
20 font size. Snowball Earth is the first of three books about the end of our present ice age. The Earth cools down very fast, and life becomes more of a struggle. Plans are made for human survival, in stasis vats on earth and in colonies in space... What will happen to the Waters family? Mum is expecting a baby, and babies can't go into stasis until they are 2 years old. Sheila and Jack the two children aren't sure about what is to happen, and if the plans are good enough for them to return to the Earth many years in the future.

What determines whether complex life will arise on a planet, or even any life at all? Questions such as these are investigated in this groundbreaking book. In doing so, the authors synthesize information from astronomy, biology, and paleontology, and apply it to what we know about the rise of life on Earth and to what could possibly happen elsewhere in the universe. Everyone who has been thrilled by the recent discoveries of extrasolar planets and the indications of life on Mars and the Jovian moon Europa will be fascinated by Rare Earth, and its implications for those who look to the heavens for companionship.
"Through the contributions of more than sixty leading experts in the field, Comparative Climatology of Terrestrial Planets sets forth the foundations for this emerging new science and brings the reader to the forefront of our current understanding of atmospheric formation and climate evolution"--Provided by publisher.
When it comes to big science, very few things are conclusively known. From Quantum Mechanics to Natural Selection, what we have instead are theories - ideas explain why things happen the way they do. We don't know for certain these are correct - no one ever saw the Big Bang - but with them we can paint beautiful, breathtaking pictures of everything from human behaviour to what the future may hold. Profiling the key scientists behind each theory, "30-Second Theories" presents each entry in a unique, eye-catching full-colour design, with thought-provoking extras and stylish illustrations. It is essential for anyone keen on expanding their mind with science's most thrilling ideas.
Determining the precise timing for the evolutionary origin of groups of organisms has become increasingly important as scientists from diverse disciplines attempt to examine rates of anatomical or molecular evolution and correlate intrinsic biological events to extrinsic environmental events. Molecular clock analyses indicate that many major groups are twice as old, or more, than a literal reading of the fossil record attests, implying that the fossil record is incomplete. Few paleontologists agree that the fossil record is inadequate, arguing instead that our understanding of the molecular clock is far from ideal. Telling the Evolutionary Time: Molecular Clocks and the Fossil Record represents a discussion between molecular biologists and paleontologists, in which they investigate the significance of competing sources of data, explain the nature of molecular clocks and the fossil record, and strive to develop compromise models that incorporate contradictory opinions. These are presented as a series of case studies dealing with many of the most important groups of complex organisms, such as protists, land plants, flowering plants, complex animals, chordates, vertebrates, tetrapods, and modern birds. Bringing fresh insight and various perspectives to a complicated argument, this book assembles all sides of the debate into one comprehensive text. It is a significant volume for research scientists and advanced students across the field of evolutionary biology.
