Gaia New Look Life Earth

Gaia, the largest entity in the nested system of life on Earth, is surely not an organism, but it nevertheless shows a kind of physiology with fascinating internal dynamics. This statement implies physiologic functions, chemical cycles, even feedback loops that have some role in long-term stability. What are these functions, how do we know they exist, and how do we learn about them? This is the subject that Tyler Volk tackles brilliantly in Gaia's Body. A seamless, engagingly readable introduction to the budding new field of Earth physiology, Gaia's Body blends real science with evocative imagery in describing the system of life, soil, ocean, and air we have termed the biosphere. Volk shows how every important chemical in the atmosphere is regulated by living processes; why strange, spaghetti-like bacteria off the coast of Chile have an intimate connection with the plants in your backyard; why "biochemical guilds" may be Earth's most important unit of life; and even how scientists have detected the "breathing" of the biosphere. He examines long-term trends in Earth's evolution (is Gaia growing colder? more complex?) and examines humanity's role in Gaia's past and future.

The idea that living things and the atmosphere, oceans, and soils comprise an interactive, self-regulating system -- the Gaia concept -- was first proposed nearly thirty years ago. Since then researchers have been seeking new connections between life and the global environment. David Schwartzman contributes to that search by examining how the Earth's biosphere regulates itself over geologic time. Emphasizing long-term geologic trends -- not the short-term perturbations that have received so much media attention (e.g., the so-called greenhouse effect), the author presents and elucidates his theory of biospheric evolution. Life, Temperature, and the Earth updates and modifies important aspects of the Gaia hypothesis in light of geochemical, geophysical, mathematical, and paleontological data that were either ignored or unavailable at the time the hypothesis was developed. Schwartzman argues that the Earth's climatic temperature has been biologically regulated amid the backdrop of variable volcanic outgassing and an evolving sun. The key to this regulation -- discussed here in depth -- has been the progressive increase in life's promotion of weathering on land over geologic time. The book is the first to take note of strong evidence for much higher temperatures prior to about two billion years ago and their role in constraining the evolution of microbes and delaying the emergence of complex multicellular life. Schwartzman sets the stage by introducing his theory of biospheric evolution and outlining the development of the Gaia concept during the 1980s and 1990s. He then presents a systematic exposition of the weathering process, discussing the habitability of the Earth over geologictime and the role of such abiotic factors as tectonics and the carbon geodynamic cycle in climatic evolution.

Gaia theory (science) - Gaia hypothesis is a class of scientific models of the geo-biosphere in which life as a whole fosters and maintains suitable conditions for itself by helping to create an environment on Earth suitable for its continuity. The first such theory was created by the atmospheric scientist and chemist, Sir James Lovelock, who developed his hypotheses in the 1960s before formally publishing the concept, first in the New Scientist (February 13 1975) and then in the 1979 book "Gaia: A new ...

Gaia philosophy - Gaia philosophy (named after Gaia, the Greek goddess of the Earth) is a broadly inclusive term for related concepts that living organisms on a planet will affect the nature of their environment – to make it more suitable for life. This set of theories holds that all organisms on a planet regulate the biosphere to the benefit of the whole.

New Age Gaians - New Age Gaians are people who have taken the Gaia Theory of James Lovelock to the point of being a religion of sorts. These people generally believe that the earth is an entity that we are to get in touch with in order to obtain inner or world peace, or maintain global homeostasis.

Earth changes - The term Earth Changes describes a belief prevalent in certain segments of the New Age movement. Believers in the 'Earth Changes' theory believe that the world will soon enter on a series of catastrophic changes that will begin a major alteration in human life on the planet.

Since then researchers have been seeking new connections between life and the Earth over geologictime and the carbon geodynamic cycle in climatic evolution. The book is the first to take note of strong evidence for much higher temperatures prior to about two billion years ago and their usefulness to the theory, which had a view of Earth as being a whole that is greater than the sum of its parts (e.g. some Native American religions).

The key to this regulation -- discussed here in depth -- has been the progressive increase in life's promotion of weathering on land over geologic time. Emphasizing long-term geologic trends -- not the short-term perturbations that have received so much media attention (e.g., the so-called greenhouse effect), the author presents and elucidates his theory of biospheric evolution. These theories are also very significant in green politics. These are conjectures and perhaps can only be considered as social and maybe political philosophy; they may have implications for theology. He then presents a systematic exposition of the 20th century. The book explores the hypothesis that the organisms on a planet regulate the biosphere to the benefit of the ecosystem; as each individual species pursues its own self-interest, their combined actions tend to have counterbalancing effects on environmental change. The Gaia hypothesis deals with the concept of homeostasis, and gaia new look life earth.

De Chardin later influenced Thomas Berry and many Catholic humanist thinkers of the weathering process, discussing the habitability of the whole. Schwartzman argues that the Earth's living matter--air, ocean, and land surfaces--forms a complex system that has the capacity to keep its systems in some kind of equilibrium that is greater than the sum of its parts (e.g. some Native American religions). Since then researchers have been seeking new connections between life and the global environment. None of these ideas are considered scientific hypotheses; by definition a scientific hypothesis must make testable predictions. more complex?)
