On Gaia

A critical examination of James Lovelock's controversial Gaia hypothesis 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.

Gaia, in which James Lovelock puts forward his inspirational and controversial idea that the Earth functions as a single organism, with life influencing planetary processes to form a self-regulating system aiding its own survival, is now a classic work that continues to provoke heated scientific debate.

• Examines how integrating important alchemical images with Gaian science can offer insights into our interconnectedness with Gaia • Looks at how the four components of the living earth--biosphere, atmosphere, hydrosphere, and lithosphere--mesh with the four elements of alchemical theory and the four functions of consciousness as understood by depth psychology • Offers guided meditations and contemplative exercises to open your receptivity to messages from the biosphere and help you connect more deeply with Gaia During the scientific revolution, science and soul were drastically separated, propelling humanity into four centuries of scientific exploration based solely on empiricism and rationality. But, as scientist and ecologist Stephan Harding, Ph.D., demonstrates in detail, by reintegrating science with profound personal experiences of psyche and soul, we can reclaim our lost sacred wholeness and help heal ourselves and our planet. The book begins with compelling introductions to depth psychology, alchemy, and Gaia theory--the science of seeing the Earth as an intelligent, self-regulating system, a theory pioneered by the author’s mentor James Lovelock. Harding then explores how alchemy, as understood through the depth psychology of C. G. Jung, offers us powerful methods of reuniting rationality and intuition, science and soul. He examines the integration of important alchemical engravings, including those from L’Azoth des Philosophes and the Rosarium Philosophorum, with Gaian science. He shows how the seven key alchemical operations in the Azoth image can help us develop deeply transformative experiences and insights into our interconnectedness with Gaia. He then looks at how the four components of the living Earth--biosphere, atmosphere, hydrosphere, and lithosphere--mesh not only with the four elements of alchemical theory but also with the four functions of consciousness from depth psychology. Woven throughout with the author’s own experiences of Gaia alchemy, the book also offers guided meditations and contemplative exercises to open your receptivity to messages from the biosphere and help you develop your own Gaian alchemical way of life, full of wonder and healing.

This classic work is reissued with a new preface by the author. Written for non-scientists the idea is put forward that life on Earth functions as a single organism.

Working up the courage to take a big, important leap is hard, but Jabari is almost absolutely ready to make a giant splash. Jabari is definitely ready to jump off the diving board. He’s finished his swimming lessons and passed his swim test, and he’s a great jumper, so he’s not scared at all. “Looks easy,” says Jabari, watching the other kids take their turns. But when his dad squeezes his hand, Jabari squeezes back. He needs to figure out what kind of special jump to do anyway, and he should probably do some stretches before climbing up onto the diving board. In a sweetly appealing tale of overcoming your fears, newcomer Gaia Cornwall captures a moment between a patient and encouraging father and a determined little boy you can’t help but root for.

This is Guy Laliberté documentation of his experience in space featuring his photographs of Earth as seen from the International Space Station. Captivated by the beauty of the surface of the Earth, Laliberté’s photos show the colors and textures visible only 220 miles away. A stable subject and a moving photographer - the ISS is moving at 17,500 miles per hour, doing 6 tours of the earth every 24 hours - made for truly original conditions. Using the Nikon D3S and Nikon D3X digital-SLR cameras, deserts resemble contemporary abstract paintings, cities rise up like mini-mountain ranges, and faces and figures are revealed in nature. 'Gaia' is the tour de force of Cirque du Soleil founder Guy Laliberté. A hand-bound limited edition with color plates presented in a linen clamshell box.

The emergence of modern sciences in the seventeenth century profoundly renewed our understanding of nature. For the last three centuries new ideas of nature have been continually developed by theology, politics, economics, and science, especially the sciences of the material world. The situation is even more unstable today, now that we have entered an ecological mutation of unprecedented scale. Some call it the Anthropocene, but it is best described as a new climatic regime. And a new regime it certainly is, since the many unexpected connections between human activity and the natural world oblige every one of us to reopen the earlier notions of nature and redistribute what had been packed inside. So the question now arises: what will replace the old ways of looking at nature? This book explores a potential candidate proposed by James Lovelock when he chose the name 'Gaia' for the fragile, complex system through which living phenomena modify the Earth. The fact that he was immediately misunderstood proves simply that his readers have tried to fit this new notion into an older frame, transforming Gaia into a single organism, a kind of giant thermostat, some sort of New Age goddess, or even divine Providence. In this series of lectures on 'natural religion,' Bruno Latour argues that the complex and ambiguous figure of Gaia offers, on the contrary, an ideal way to disentangle the ethical, political, theological, and scientific aspects of the now obsolete notion of nature. He lays the groundwork for a future collaboration among scientists, theologians, activists, and artists as they, and we, begin to adjust to the new climatic regime.
