Of Homeostatic Gaia, Kirchner recognised two alternatives. The Gaia hypothesis was initially criticized for being teleological and against the principles of natural selectionbut later refinements aligned the Gaia hypothesis with ideas from fields such as Earth system sciencebiogeochemistry and systems ecology.

When CO 2 levels rise in the atmosphere the temperature increases and plants grow. Turn recording back on.

However, in the early s, W. Toward a Physiology of Earth. Topics related to the hypothesis include how the biosphere and the evolution of organisms affect the stability of global temperaturesalinity of seawateratmospheric oxygen levels, the maintenance of a hydrosphere of liquid water and other environmental variables that affect the habitability of Earth. There was so much information to be gathered and sorted.

Oxygen is a reactive compound, and should eventually combine with gases and minerals of the Earth’s atmosphere and crust. Brightness temperature Effective temperature Geologic record Hiatus Historical climatology Instrumental hipottesis Paleoclimatology Paleotempestology Proxy data Record of the past 1, years Satellite measurements. According to the data gathered by the Pic du Midi observatoryplanets like Mars or Venus had atmospheres in chemical equilibrium.

Vernadsky was a Ukrainian geochemist and was one of the first scientists to recognize that the oxygen, nitrogen, and carbon dioxide in the Earth’s atmosphere hipltesis from biological processes.

The Gaia hypothesis posits that the Earth is a self-regulating complex system involving the biospherethe atmospherethe hydrospheres and the pedospheretightly coupled as an evolving system.

Would we mine our livers for nutrients for some short-term benefit? It would appear that the gaja that Gaia acts “intentionally” was a metaphoric statement in his popular initial book and was not meant to be taken literally.

Potential effects and issues. Hutton went on to make the analogy between the circulation of the blood, discovered by Harvey, and the circulation of the nutrient elements of the Earth and of the way that sunlight distills water from the oceans so that it may later fall as rain and so refresh the earth.

It is unlikely that its presence would have been sought but for the stimulus of Gaia theory. The unorthodox composition of the atmosphere radiates so strong a signal in the infrared range that it could be recognized by a spacecraft far outside the solar system.

Is nature really motherly?

There must be many others. 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. Two scientists, however, thought otherwise; one was the eminent biologist Lynn Margulis and the other the geochemist Lars Sillen. This wholesome view of our planet did not persist into the next century. James Hutton and the philosophy of geology.

James Lovelock gave this name to his hypothesis after a suggestion from the novelist William Goldingwho was living in the same village as Lovelock at the time BowerchalkeWiltshireUK. The Fabric of Geology.

Staley has similarly proposed ” In brief, scientists said, the idea was teleological and untestable. In the biogeochemical processes of the earth, sources and sinks are the movement of elements.

By taking the species lovelcok the environment together, something no theoretical ecologist has done, the classic mathematical instability of population biology models is cured. It involves action at a personal level. Lynn Margulis was my first collaborator Margulis and Lovelock, The constant ocean salinity was a long-standing mystery, because no process counterbalancing the salt influx from rivers was known.
