The web of life: The Gaia hypothesis continues to be broadly skeptically received by the scientific community. A Biography of Our Living Earth.

For example, against the charge that Gaia was teleological, Lovelock and Andrew Watson offered the Daisyworld Model and its modifications, above as evidence against most of these criticisms.

Retrieved 1 December Hypothesis that living organisms interact with their surroundings in a self-regulating system.

Archived from the original PDF on Kirchner claimed that Lovelock and Gia had not presented one Gaia hypothesis, but four. In such case we would have all the visible attributes of a living thing, which we do not realize to be such because it is too big, and its life processes too slow. Lovelock suggested detecting such combinations in other planets’ atmospheres as a relatively reliable and cheap way to detect life.


Basic Books,p. The stability of the atmosphere in Earth is not a consequence of chemical equilibrium. Carbon capture and storage Efficient energy use Low-carbon economy Nuclear power Renewable energy.

Archived from the original on February 23, Vernadsky was a pioneer of the scientific bases for the environmental sciences. The elements that comprise salinity do not readily change and are a conservative property of seawater.

HIPÓTESIS GAIA by loreto cabrera on Prezi

Biogeochemical Selection or Gaia? Lovelock has suggested that global biological feedback mechanisms could evolve by natural selectionstating that organisms that improve their environment for their survival do better than those that damage their environment. One of these organisms is Emiliania huxleyian abundant coccolithophore algae which also has a role in the formation of clouds.

In accentuating the direct competition between individuals for hupotesis as the primary selection mechanism, Darwin and especially his followers created the impression that the environment was simply a static arena”.

Gaia hypothesis

Lovelock has also hypothesised that methanogens produced elevated levels of methane in gaiz early atmosphere, giving a view similar to that found in petrochemical smog, similar in some respects to the atmosphere on Titan. Lovelock states that the initial formulation was based on observation, but still lacked a scientific explanation. 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.

Animate Earth Science, Intuition and Gaia. Gaia scientists see the participation of living organisms in the carbon cycle as one of the complex processes that maintain conditions suitable hlpotesis life. Topics related to the hypothesis include how the biosphere and gaiw 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.

These processes establish a global control system that regulates Earth’s surface temperatureatmosphere composition and ocean salinitypowered by the global thermodynamic disequilibrium state of the Earth system. Oxygen is a reactive compound, and should eventually combine with gases and minerals of the Hi;otesis atmosphere and crust.

Prefazione di Enrico Bellone. The New York Times Magazine. Among many other speakers: 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.

Damming glacial lakes Desalination Drought tolerance Irrigation investment Rainwater storage Sustainable development Weather modification. The constant ocean salinity was a long-standing mystery, because no process counterbalancing the salt influx from rivers was known.

EAndreae, M. Later, other relationships such as sea creatures producing sulfur and iodine in approximately the same quantities as required by land creatures emerged and helped bolster the hypothesis. The Gaia hypothesis states that the Earth’s atmospheric composition is kept at a dynamically steady state by the presence of life. It is at least not impossible to hioptesis the earth’s parts—soil, mountains, rivers, atmosphere etc,—as organs or parts of organs of a coordinated whole, each part with its definite function.

Stephen Jay Gould criticised Gaia as being “a metaphor, not a hi;otesis.
