In The Medea Hypothesis, renowned paleontologist Peter Ward proposes a revolutionary and provocative vision of life's relationship with the Earth's biosphere--one that has frightening implications for our future, yet also offers hope. Using the latest discoveries from the geological record, he argues that life might be its own worst enemy. This stands in stark contrast to James Lovelock's Gaia hypothesis--the idea that life sustains habitable conditions on Earth. In answer to Gaia, which draws on the idea of the "good mother" who nurtures life, Ward invokes Medea, the mythical mother who killed her own children. Could life by its very nature threaten its own existence? According to the Medea hypothesis, it does. Ward demonstrates that all but one of the mass extinctions that have struck Earth were caused by life itself. He looks at our planet's history in a new way, revealing an Earth that is witnessing an alarming decline of diversity and biomass--a decline brought on by life's own "biocidal" tendencies. And the Medea hypothesis applies not just to our planet--its dire prognosis extends to all potential life in the universe. Yet life on Earth doesn't have to be lethal. Ward shows why, but warns that our time is running out. Breathtaking in scope, The Medea Hypothesis is certain to arouse fierce debate and radically transform our worldview. It serves as an urgent challenge to all of us to think in new ways if we hope to save ourselves from ourselves.

One of the enduring questions about our planet is how it has remained continuously habitable over vast stretches of geological time despite the fact that its atmosphere and climate are potentially unstable. James Lovelock's Gaia hypothesis posits that life itself has intervened in the regulation of the planetary environment in order to keep it stable and favorable for life. First proposed in the 1970s, Lovelock's hypothesis remains highly controversial and continues to provoke fierce debate. On Gaia undertakes the first in-depth investigation of the arguments put forward by Lovelock and others--and concludes that the evidence doesn't stack up in support of Gaia. Toby Tyrrell draws on the latest findings in fields as diverse as climate science, oceanography, atmospheric science, geology, ecology, and evolutionary biology. He takes readers to obscure corners of the natural world, from southern Africa where ancient rocks reveal that icebergs were once present near the equator, to mimics of cleaner fish on Indonesian reefs, to blind fish deep in Mexican caves. Tyrrell weaves these and many other intriguing observations into a comprehensive analysis of the major assertions and lines of argument underpinning Gaia, and finds that it is not a credible picture of how life and Earth interact. On Gaia reflects on the scientific evidence indicating that life and environment mutually affect each other, and proposes that feedbacks on Earth do not provide robust protection against the environment becoming uninhabitable--or against poor stewardship by us.

Climate change has been the subject of thousands of books and magazines, scientific journals, and newspaper articles daily. It’s a subject that can be very political and emotional, often blurring the lines between fact and fiction. The vast majority of research, studies, projections and recommendations tend to focus on the human influence on climate change and global warming as the result of CO2 emissions, often to the exclusion of other threats that include population growth and the stress placed on energy sources due to emerging global affluence. Climate Vulnerability seeks to strip away the politics and emotion that surround climate change and will assess the broad range of threats using the bottom up approach—including CO2 emissions, population growth, emerging affluence, and many others—to our five most critical resources: water, food, ecosystems, energy, and human health. Inclusively determining what these threats are while seeking preventive measures and adaptations is at the heart of this unique reference work. Takes a Bottom-Up approach, addressing climate change and the threat to our key resources at the local level first and globally second, providing a more accurate and inclusive approach. Includes extensive cross-referencing, which is key to readers as new connections between factors can be discovered. Cuts across a number of disciplines and will appeal to Biological Science, Earth & Environmental Science, Ecology, and Social Science, comprehensively addressing climate change and other threats to our key resources from multiple perspectives

Das kleine Buch der Stringtheorie bietet eine knappe und unterhaltsame Einführung in eines der meistdiskutierten Gebiete der modernen Physik. Die Stringtheorie gilt als eine „Theorie für Alles“, mit der sich sämtliche Grundkräfte der Natur beschreiben lassen. Bisher allerdings konnte sie experimentell nicht bestätigt werden, und unter Physikern wird sie sehr kontrovers diskutiert. Dieses Buch gibt Ihnen die Gelegenheit, sich ein eigenes Bild zu machen!

Das berühmte Standardwerk von Simone de Beauvoir. Die universelle Standortbestimmung der Frau, die aus jahrtausendealter Abhängigkeit von männlicher Vorherrschaft ausgebrochen ist, hat nichts an Gültigkeit eingebüßt. Die Scharfsichtigkeit der grundlegenden Analyse tritt in der Neuübersetzung noch deutlicher hervor.

Ökologien der Erde bestimmen die Gegenwart. Dabei gewinnt die in den 1970er Jahren von James Lovelock gemeinsam mit Lynn Margulis entwickelte Gaia-Theorie heute neue ErklÄrungskraft. Wenn Gaia bei Bruno Latour sogar zum allgemeinen Modell der WelterklÄrung im 21. Jahrhundert wird, gilt es, nach der PlausibilitÄt zu fragen, die die Rede von Gaia aktuell entwickelt. Die vier BeitrÄge des Bandes geben hierauf eine Antwort, indem sie die metaphorologischen und begriffshistorischen Linien der Gaia-Theorie nachzeichnen und ihren Bezug auf zeitgenÖssische Computersimulationen in den Blick nehmen. So wird der gegenwÄrtige Ort des Wiederauflebens Gaias deutlich - und damit die VerschrÄnkung von kybernetischen und organizistischen Ökologien mit der Annahme einer Programmierbarkeit von Umgebungen.
