Hands up for the Gaia hypothesis

  title={Hands up for the Gaia hypothesis},
  author={James E. Lovelock},
The concept of Gaia, a self-regulating Earth, excites both admiration and obloquy. Its inventor (or rather re-discoverer) describes the genesis and evolution of the hypothesis. 
Gaia and natural selection
Evidence indicates that the Earth self-regulates at a state that is tolerated by life, but why should the organisms that leave the most descendants be the ones that contribute to regulating theirExpand
The Concept of ‘Gaia’
The Gaia theory of James Lovelock proposes that the Earth is a self-regulating system, or super-organism, maintaining conditions hospitable to contemporary planetary biota. Objections to this theory,Expand
Lovelock ' s initial hypothesis

The Gaia hypothesis is an ecological hypothesis proposing that the biosphere and the physical components of the Earth (atmosphere, cryosphere, hydrosphere and lithosphere) are closely integrated toExpand
Using the Gaia Hypothesis to Synthesize an Introductory Biology Course.
A study of the Gaia Hypothesis in a biology course illustrates to the students the development of a current scientific hypothesis, and the creative integration between different aspects of biology and between biology and other disciplines which often result in theDevelopment of new and novel hypotheses.

Economics of the Anthropocene: An Exploratory Essay
This essay summarizes some essential aspects of my recent contributions to ecological and evolutionary economics, in a way accessible to a general readership. I concentrate on the relationshipExpand
James Lovelock’s Gaia hypothesis: "A New Look at Life on Earth" ... for the Life and the Earth sciences
After a career as a chemist and engineer, James Lovelock proposed the Gaia hypothesis in the 1970’s with Lynn Margulis, a biologist. The hypothesis highlights the important influence that livingExpand

Concerns about the anthropogenic ecological degradation of the planet—deforestation, species endangerment, pollution, and an increasing carbon footprint—have prompted numerous studies calling forExpand
Vernadsky's Biosphere Concept: An Historical Perspective
PERHAPS it is no accident that as we approach the end of this century, some ideas that had emerged at its beginning are being reexamined by the scientific community. Although they are rarely embracedExpand
Chaos: Implications for forecasting☆
Abstract Uncertainty and complexity, while relatively new concepts in the social and economic spheres, have been long recognized in ecology and biophysics. Despite the element of human choice,Expand


Geophysiology, the science of Gaia
The Gaia hypothesis postulates that the climate and chemical composition of the Earth's surface environment is, and has been, regulated at a state tolerable for the biota. This notion was introducedExpand
Unpleasant surprises in the greenhouse?
There is now clear evidence that changes in the Earth's climate may be sudden rather than gradual. It is time to put research into the build-up of carbon dioxide in the atmosphere on a better footing.
Gaia as seen through the atmosphere
Life can flourish only within a narrowly circumscribed range of physical and chemical states and since life began the Earth has kept within this range. This is remarkable for there have been majorExpand
Life span of the biosphere
There has been life on Earth for at least 3,500 Myr but the assumption that a comparable future lies ahead may not be justified. Main sequence stars appear to increase their burning rate as they age.Expand
Biological modulation of the Earth's atmosphere
Abstract We review the evidence that the Earth's atmosphere is regulated by life on the surface so that the probability of growth of the entire biosphere is maximized. Acidity, gas compositionExpand
Book-Review - the Chemical Evolution of the Atmosphere and Oceans
In this first full-scale attempt to reconstruct the chemical evolution of the Earth's atmosphere and oceans, Heinrich Holland assembles data from a wide spectrum of fields to trace the history of theExpand
Biotic enhancement of weathering and the habitability of Earth
AN important question in the Earth sciences is the role of the biota in the chemical weathering of silicate rocks, which affects atmospheric CO2 and therefore climate1-10. No comprehensive study ofExpand
A negative feedback mechanism for the long‐term stabilization of Earth's surface temperature
We suggest that the partial pressure of carbon dioxide in the atmosphere is buffered, over geological time scales, by a negative feedback mechanism in which the rate of weathering of silicateExpand
Terrestrial feedback in atmospheric oxygen regulation by fire and phosphorus
The regulation of atmospheric oxygen levels (pO2) occurs on million-year timescales and is effected by modulation of sedimentary organic carbon burial and weathering rates1,2. Until recently it wasExpand
Life detection by atmospheric analysis
Abstract Living systems maintain themselves in a state of relatively low entropy at the expense of their nonliving environments. We may assume that this general property is common to all life in theExpand
