An Introduction to the Earth-Life System. Chapter 5 3rd Edition. When seeking to act personally in favor of Gaia through moderation, I find it helpful to think of the three deadly Cs: Archived from the original on February 23, Abrupt climate change Anoxic event Arctic dipole anomaly Arctic haze Arctic methane emissions Climate change and agriculture Climate change and ecosystems Climate change and gender Climate change and poverty Drought Economics of global warming Effects on plant biodiversity Effects on health Effects on humans Effects on marine mammals Environmental migrant Extinction risk from global warming Fisheries and climate change Forest dieback Industry and society Iris hypothesis Megadrought Ocean acidification Ozone depletion Physical impacts Polar stratospheric cloud Regime shift Retreat of glaciers since Runaway climate change Sea level rise Season creep Shutdown of thermohaline circulation.
Constraints on adaptation locelock important for planetary self-regulation”. Can it be tested? Carbon capture loevlock storage Efficient energy use Low-carbon economy Nuclear power Renewable energy. I see the world as a living organism of which we are a part; not the owner, nor the tenant, not even a passenger. Gaia always operates like this to achieve her altruism.
Ocean salinity has been constant at about 3. 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.
Hipotesis GAIA by Laura Flechas Mejia on Prezi
Most accusations of teleologism ceased, following this conference. The hypothesis was formulated by the chemist James Lovelock  and co-developed by the microbiologist Lynn Margulis in the s. A geophysiological system always begins with the action of an individual organism. The stability of the atmosphere in Earth is not a consequence of chemical equilibrium.
The Gaia hypothesis continues to be broadly skeptically received by the scientific community. Because we are sentient there are alternatives, both good and bad.
This model is powerfully homeostatic and can resist large perturbations not only of solar output but also of plant population. It was all too easy to lose sight of the picture in the searching and sorting of the pieces.
It affects even Darwin’s great vision, for it may no longer hiptesis sufficient to say that organisms that leave the most progeny will succeed. Gaia tra mito e scienza.
Many processes in the Earth’s surface essential for the conditions of life depend on the interaction of living forms, especially microorganismswith inorganic elements. Calcium carbonate is used by living organisms to manufacture carbonaceous tests and shells.
The latter is the “weakest” form of Gaia that Lovelock has advocated. Brightness temperature Effective temperature Geologic record Hiatus Historical climatology Instrumental record Paleoclimatology Paleotempestology Proxy data Record of the past 1, years Satellite measurements.

Retrieved 19 October Are we doomed to precipitate a change from the present comfortable state of the Earth to one almost certainly unfavorable for us but comfortable to the new biosphere of our successors? There is no foresight or planning involved. Lovelock gave evidence of this in his second book, showing the evolution from the lovelovk of the early thermo-acido-philic and methanogenic bacteria towards the oxygen-enriched atmosphere today that lovrlock more complex life.
It has a profound significance for biology. This new statement of the Gaia hypothesis was more acceptable to the scientific community. When seen in infrared light, the Earth is a strange and wonderful anomaly among the planets of the solar system.
Opponents of this view sometimes reference examples of events that resulted in dramatic change rather than stable equilibrium, such as the conversion of the Earth’s atmosphere from a reducing environment to an oxygen -rich one at the end of the Archaean and the beginning of the Proterozoic periods.
