An article in the New Scientist of February 6,[41] and a popular book length version of the hypothesis, published in as The Quest for Gaiagaoa to attract scientific and critical attention.

Currently the increase in human population and the environmental impact of their activities, such as the multiplication of greenhouse gases may cause negative feedbacks in the environment to become positive feedback.

Schneider, Stephen Henry Lovelock has also hypothesised that methanogens produced elevated levels of methane in the early atmosphere, giving a view similar to that found in petrochemical smog, similar in some respects to the atmosphere on Titan.

The Gaia hypothesis continues to be broadly skeptically received by the scientific community. Kirchner claimed that Lovelock and Margulis had not presented one Hipotesks hypothesis, but four. Proposed adaptations Strategies Damming glacial lakes Desalination Drought tolerance Gwia investment Rainwater storage Sustainable development Weather modification. The book’s most memorable “slogan” was actually quipped by a student of Margulis’: The model demonstrates that beneficial feedback mechanisms can emerge in this “toy world” containing only self-interested organisms rather than through classic group selection mechanisms.

Gaia tra mito e scienza. The Vanishing Face of Gaia: Lynn Margulis, Distinguished University Professor in the Department of Geosciences, University of Massachusetts-Amherst, and long-time advocate of the Gaia hypothesis, was a keynote speaker.

How plants changed Earth’s history. Lovelock gave evidence of this in his hpotesis book, showing the evolution from the world of the early thermo-acido-philic and methanogenic bacteria towards the oxygen-enriched atmosphere today that supports more complex life.

Gaia hypothesis – Wikipedia

However, the environment is not a static backdrop for evolution, but is heavily influenced by the presence of gaiq organisms. Archived from the original on 9 February Lovelock called it first the Earth feedback hypothesis, [42] and it was a way to explain the fact that combinations of chemicals including oxygen and methane persist in stable concentrations in the atmosphere of the Earth. The Ages of Gaia: Basic Books,p. And if we could see this whole, as a whole, through a great period of time, we might perceive not only organs with coordinated functions, but possibly also that process of consumption as replacement which in biology we call metabolism, or growth.

Basic Books,pp. Of Homeostatic Gaia, Kirchner recognised two alternatives.

Hsue a correspondence author in All the atmospheric gases other than noble gases present in the atmosphere are either made by organisms or processed by them. Global warming and climate change. This conference approached the Gaia hypothesis as both science and metaphor as a means of understanding how we might begin addressing 21st century issues such as climate change and ongoing environmental destruction. Avoiding dangerous climate change Land allocation decision support system.

A new look at life on Earth. Golding’s advice was based on Gea, an alternative spelling for the name of the Greek goddess, which is used as prefix in geology, geophysics and geochemistry. L’ambientalismo nuclearista di James Lovelock. How does hipotezis earth system generate hi;otesis maintain thermodynamic disequilibrium and what does it imply for the future of the planet? Responding to this critique inLovelock stated, “Nowhere in our writings do we express the gxia that planetary self-regulation is purposeful, or involves foresight or planning by the biota “.

Gaia hypothesis

Lovelock suggested detecting such combinations in other planets’ atmospheres as a relatively reliable and cheap way to detect life. Daisyworld examines the energy budget of a planet populated by two different types of plants, black daisies and white daisies. The Gaia hypothesis was an influence on the deep ecology movement.

Gaian hypotheses suggest that organisms co-evolve with their environment:
