Earth system science

Earth system science
Earth system science seeks to integrate various fields of academic study to understand the Earth as a system. It considers interaction between the atmosphere, hydrosphere, lithosphere (geosphere), biosphere,[1] and heliosphere.[2] In 1996, the American Geophysical Union, in cooperation with the Keck Geology Consortium and with support from five divisions within the National Science Foundation, convened a workshop "to define common educational goals among all disciplines in the Earth sciences." In its report, participants noted that, "The fields that make up the Earth and space sciences are currently undergoing a major advancement that promotes understanding the Earth as a number of interrelated systems." Recognizing the rise of this systems approach, the workshop report recommended that an Earth system science curriculum be developed with support from the National Science Foundation.[3] Definition[edit] Inspiration in the Gaia theory[edit] The programmes have stated the following: Related:  medio ambiente

James Lovelock James Ephraim Lovelock, CH, CBE, FRS[2] (born 26 July 1919) is an independent scientist, environmentalist and futurist who lives in Dorset, England. He is best known for proposing the Gaia hypothesis, which postulates that the biosphere is a self-regulating entity with the capacity to keep our planet healthy by controlling the interconnections of the chemical and physical environment.[5] Biography[edit] Career[edit] James Lovelock around 1960 A lifelong inventor, Lovelock has created and developed many scientific instruments, some of which were designed for NASA in its program of planetary exploration. In early 1961, Lovelock was engaged by NASA to develop sensitive instruments for the analysis of extraterrestrial atmospheres and planetary surfaces. Lovelock was elected a Fellow of the Royal Society in 1974. On 8 May 2012, he appeared on the Radio Four series "The Life Scientific", talking to Jim al-Khalili about the Gaia hypothesis.

Earth spheres Wili The following outline is provided as an overview of and topical guide to earth science: Earth's spheres[edit] The Earth's spheres are the many "spheres" into which the planet Earth is divided. The four most often recognized are the atmosphere, the biosphere, the hydrosphere and the geosphere. As a whole, the system is sometimes referred to as an ecosphere.

The Language of Degeneration The Language of Degeneration: Eugenic Ideas in The Time Machine by H. G. Wells and Man and Superman by George Bernard Shaw By Jenny Jopson ‘Given the fact that so much of the eugenicists’ writings read like science fiction…it was inevitable that they should have influenced the literary portrayals of modern life’1 Introduction Wells and Shaw represent two of the foremost intellectuals of their day who were motivated to embrace the doctrine of eugenics by a hope that it could effect social change. The period of the eugenics movement2 produced many novels and plays suffused with the fear of the deterioration of the race and the language of regeneration.3 Of these, The Time Machine and Man and Superman provide the main focus for this study, representing examples of the best-known and most influential of the works of their respective authors. Contexts The perceived degeneration of the race gave extra urgency to these concerns as to the inadequacy of social reform. Science as Saviour

Earth science - Wikipedia Earth science or geoscience is an all-embracing term for the fields of science related to the planet Earth.[1] It can be considered to be a branch of planetary science, but with a much older history. There are both reductionist and holistic approaches to Earth sciences. The Earth sciences can include the study of geology, the lithosphere, and the large-scale structure of the Earth's interior, as well as the atmosphere, hydrosphere, and biosphere. Fields of study[edit] The following fields of science are generally categorized within the Earth sciences: Earth's interior[edit] A volcanic eruption is the release of stored energy from below the surface of Earth.[9] Plate tectonics, mountain ranges, volcanoes, and earthquakes are geological phenomena that can be explained in terms of energy transformations in Earth's crust.[10] Plate tectonics might be thought of as the process by which the Earth is resurfaced. Volcanoes result primarily from the melting of subducted crust material.

Gaia hypothesis The study of planetary habitability is partly based upon extrapolation from knowledge of the Earth's conditions, as the Earth is the only planet currently known to harbour life The Gaia hypothesis, also known as Gaia theory or Gaia principle, proposes that organisms interact with their inorganic surroundings on Earth to form a self-regulating, complex system that contributes to maintaining the conditions for life on the planet. Topics of interest include how the biosphere and the evolution of life forms affect the stability of global temperature, ocean salinity, oxygen in the atmosphere and other environmental variables that affect the habitability of Earth. Introduction[edit] Less accepted versions of the hypothesis claim that changes in the biosphere are brought about through the coordination of living organisms and maintain those conditions through homeostasis. Details[edit] Regulation of the salinity in the oceans[edit] Regulation of oxygen in the atmosphere[edit] Processing of CO2[edit]

It is one of the Earth's spheres.[1] As human technology becomes more evolved, such as the greater ability of technology to cause deforestation, the impact of human activities on the environment potentially increases.
