Readers Defend the Anthropocene Epoch
So it is with the Anthropocene. Humans have mixed faunas and floras globally, lopped branches from the tree of life, and greatly increased the abundance of selected species. Even if we avoid another mass extinction, we have already deflected future biological history. Human-caused changes to Earth systems are also no blip. Industrially generated CO2 already in the atmosphere (about a trillion tons, and rising) will likely eliminate the next glacial phase altogether, changing ocean chemistry and climate history for hundreds of thousands of years to come. Brannen insists that “the idea of the Anthropocene inflates our own importance by promising eternal geological life to our creations.” Scott Wing, Jan Zalasiewicz, Colin Waters, John McNeill, Will Steffen, Erle Ellis, Naomi Oreskes, Michael Wagreich, Daniel DeB.

When Did the Anthropocene Begin? A Great Climate Debate
William Ruddiman, a professor of environmental sciences at the University of Virginia, is extremely worried about climate change, but he nonetheless hopes the committee votes against both questions. For the past two years, he has lobbied its members to think of the Anthropocene not as a sudden upheaval, but as a gradual change, a slow transformation of the planet that began 5,000 years ago. “Where could you possibly pick a single start date in this ever-evolving story?” Last week, he and 23 other researchers argued the topic at length in the scientific journal Progress in Physical Geography. For Jan Zalasiewicz, a professor of geography at the University of Leicester, the answer is clear. “If you look at the main parameters of the Earth-system metabolism, then … things only began to change sharply and dramatically with industrialization,” he told me. It was “the Big Zoom,” he said, borrowing a phrase from the journalist Andrew Revkin. Ruddiman isn’t so sure.

International Society for the Systems Sciences
The International Society for the Systems Sciences (ISSS) is among the first and oldest organizations devoted to interdisciplinary inquiry into the nature of complex systems, and remains perhaps the most broadly inclusive. The Society was initially conceived in 1954 at the Stanford Center for Advanced Study in the Behavioral Sciences by Ludwig von Bertalanffy, Kenneth Boulding, Ralph Gerard, and Anatol Rapoport. In collaboration with James Grier Miller, it was formally established as an affiliate of the American Association for the Advancement of Science in 1956. Originally founded as the Society for General Systems Research, the society adopted its current name in 1988 to reflect its broadening scope. The initial purpose of the society was "to encourage the development of theoretical systems which are applicable to more than one of the traditional departments of knowledge," with the following principal aims:
Downward causation
In philosophy, downward causation is a causal relationship from higher levels of a system to lower-level parts of that system: for example, mental events acting to cause physical events,[1] The term was originally coined in 1974 by the philosopher and social scientist Donald T. Campbell.[2][1] See also[edit] References[edit] Further reading[edit] Campbell, Donald T. (1974) "Downward causation in hierarchically organised biological systems".

Donella Meadows
Origem: Wikipédia, a enciclopédia livre. Donella H. "Dana" Meadows (Illinois - EUA, 13 de Março de 1941 - Hanover, New Hampshire - 20 de fevereiro de 2001)[1] foi uma cientista ambiental, professora e escritora co-autora do livro "Os limites do crescimento", traduzido para mais de 28 idiomas, e tendo sido um best-seller mundial, influenciando o pensamento científico e social desde então.[2] Licenciou-se em química pelo Carleton College em 1963, e em 1968 obteve o doutoramento em Biofísica pela Universidade de Harvard, tendo mais tarde entrado no MIT como investigadora, onde trabalhou em estreita colaboração com Jay W. Fundou, em 1981 o INRIC (International Network of Resource Information Centres – Rede Internacional de Centros de Informação de Recursos), apelidado de Batalon group, um processo global de parcerias e troca de informações entre o mundo académico, investigadores e activistas do desenvolvimento sustentável, sendo coordenadora do projecto por 18 anos.
