The Gaia hypothesis states that the Earth’s atmospheric composition is kept at a dynamically steady state by the presence of life.

Damming glacial lakes Desalination Drought tolerance Irrigation investment Rainwater storage Sustainable development Weather modification. The existence of a planetary homeostasis influenced by living forms had been observed previously in the field of biogeochemistryand it is being investigated also in other fields like Earth system science.

By the time of the 2nd Hipotesis de gaia Conference on the Gaia Hypothesis, held at Valencia, Spain, on 23 June[50] the situation had changed significantly. Ocean salinity has been constant at about 3.

Transforma la tierra para sus propios fines. Lichen and other organisms accelerate the weathering of rocks in the surface, while the decomposition of rocks also happens faster in the soil, thanks to the activity of roots, fungi, bacteria and subterranean animals.

Retrieved August 27, The originality of the Gaia hypothesis relies on the assessment that such homeostatic balance is actively pursued with the goal of keeping the optimal hipotesis de gaia for life, even when terrestrial or external events menace them.

The Gaia hypothesis has since been supported by a number of scientific experiments [43] and provided a number of useful predictions. In some versions of Gaia philosophyall lifeforms are considered part of one single living planetary being called Gaia. Gaia tra mito e scienza. Gaia scientists see the participation of living organisms in the carbon cycle as one of the complex processes that maintain conditions suitable for life. Schneider, Stephen Henry Gaia scientists see the participation of living organisms in the carbon cycle as one of the complex processes that maintain conditions suitable for life.

Some people attended. The Gaia hypothesis has since been supported by a number of scientific experiments [44] and provided a number of useful predictions.

Of Homeostatic Gaia, Kirchner recognised two alternatives. Dry air in the atmosphere of Earth contains roughly by volume Carbon dioxide removal Carbon sink Climate action Climate Action Plan Climate change mitigation scenarios Climate engineering Individual and political action on climate change Reducing emissions from deforestation and forest degradation Reforestation Urban reforestation.

Daisyworld examines the energy budget of a planet populated by two different types of plants, black daisies and white daisies. Aside from clarifying his language and understanding of what is meant by a life form, Lovelock himself ascribes most of the criticism to a lack of understanding of non-linear mathematics by his critics, and a linearizing form of greedy reductionism in which hipotesis de gaia events have to be immediately ascribed to specific causes before the fact.

Hipotesis de gaia accepted gaua of the hypothesis claim that changes in the hipotesis de gaia are brought about through the coordination of living hipotesis de gaia and maintain those conditions through homeostasis. Most accusations of teleologism ceased, following this conference.

Gaia hypothesis – Wikipedia

It would appear that the claim that Gaia acts “intentionally” was a metaphoric statement in his popular initial book and was not meant to be taken literally. James Lovelock and Andrew Watson developed the mathematical model Daisyworldin which temperature regulation arises from a simple ecosystem dee of two species whose activity varies in response to the planet’s environment.

An example is how the activity of photosynthetic bacteria during Precambrian times have completely modified the Earth atmosphere to turn it aerobic, and as such supporting evolution of life in particular eukaryotic life. 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 Gaiabegan to attract scientific and critical attention.

Responding to this critique inLovelock stated, “Nowhere in our writings do we express the idea that planetary self-regulation is purposeful, or involves foresight or planning by the biota “. Lovelock has stated that this could bring an hipotesis de gaia accelerated global warming[18] but he has since stated the effects will likely occur more slowly.

However, he finds that the two weaker forms of Gaia—Coeveolutionary Gaia and Influential Gaia, which assert that there are close links between the evolution of life and the environment and that biology affects the physical and chemical environment—are both credible, but that it is not useful to use the term “Gaia” in this sense. The Earth is about to catch a morbid fever16 January Lovelock gave evidence of this in his second 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 scientists vaia the participation of living organisms in ve carbon cycle as one of the complex processes that hipotesis de gaia conditions suitable for life. Vernadsky was a pioneer of the scientific bases for the environmental sciences. Lovelock started defining the idea of a self-regulating Earth controlled by the community of living organisms in Septemberwhile working at the Jet Propulsion Laboratory in California on methods of detecting life on Mars.

When CO 2 levels rise in the atmosphere the temperature increases and plants grow. Send this gaiaa to hipotesis de gaia others join your presentation: The Ages of Gaia: James Lovelock called his first proposal the Gaia hypothesis but has also used the term Gaia theory. Another influence for the Gaia hypothesis and the environmental movement in general came as a side effect of the Space Race between the Soviet Union and the United States of America.

Many scientists in particular also criticised the approach taken in his popular book Gaia, a New Look at Life on Earth for being teleological —a belief that things are purposeful and aimed towards a goal.
