Anthropocene The Anthropocene is an informal geologic chronological term that marks the evidence and extent of human activities that have had a significant global impact on the Earth's ecosystems. The term was coined in the 1980s[1] by ecologist Eugene F. Stoermer and has been widely popularized by the Nobel Prize-winning atmospheric chemist, Paul Crutzen, who regards the influence of human behavior on the Earth's atmosphere in recent centuries as so significant as to constitute a new geological epoch for its lithosphere. To date, the term has not been adopted as part of the official nomenclature of the geological field of study. In 2008 a proposal was presented to the Stratigraphy Commission of the Geological Society of London to make the Anthropocene a formal unit of geological epoch divisions.[2] A large majority of that Stratigraphy Commission decided the proposal had merit and should therefore be examined further.

Kevin Costner Shows Machine that Extracts 97% of Oil From Water (Video) Screen grabs: Youtube Wants to Use it on BP Oil Spill If you don't know about the BP oil spill by now, you've probably been living in a cave for the past few weeks. This Makes Up for Waterworld From what has been revealed, it seems like there's a centrifuge inside of the machine that helps it separate the oil from the water (because of their different densities). Costner helped fund the development of this machine 15 years ago.

NASA officials released this statement on the study on March 20, which seeks to distance the agency from the paper: "A soon-to-be published research paper, 'Human and Nature Dynamics (HANDY): Modeling Inequality and Use of Resources in the Collapse or Sustainability of Societies' by University of Maryland researchers Safa Motesharrei and Eugenia Kalnay, and University of Minnesota's Jorge Rivas, was not solicited, directed or reviewed by NASA. It is an independent study by the university researchers utilizing research tools developed for a separate NASA activity. As is the case with all independent research, the views and conclusions in the paper are those of the authors alone. NASA does not endorse the paper or its conclusions." Read the original story below. Civilization was pretty great while it lasted, wasn't it? Science will surely save us, the nay-sayers may yell. Economic growth is the biggest destroyer of the ecology.
Living On a New Earth Forget banking and the automotive industry. Earth is the one system that is truly “too big to fail.” For centuries humans have used up the planet’s resources, saddled it with our waste and simply moved on when a wellspring dried up or the back forty became polluted. But now we’ve exhausted that strategy. Scientists, social thinkers and the global public are realizing that humankind has transformed the natural planet into an industrialized one, and we must transition again to a sustainable planet if we are to survive. So what is the bailout plan?

Life After People The very notion is deliciously ghoulish: What happens to earth if - or when - people suddenly vanished? The History Channel presents a dramatic, fascinating what-if scenario, part science fiction and part true natural science. Welcome to Earth, Population: 0 is the catchy tagline, Life After People's 94 minutes are so gripping you nearly forget while you watch that you, yourself, will be gone too. It turns out that earth can go along very nicely without us. The impact of the lack of people will be noticed right away, as most power grids shut down around the planet. Elsewhere, critters and plants will have their run of Manhattan and every other previously "civilized" spot. Watch the full documentary now - Season 1 (playlist - 14 hours)
Un grand retournement se prépare, en travaillant les alternatives Interview par Michel Janva pour le Salon Beige, 6 novembre 2019. Pierre de Lauzun (X et ENA), ancien directeur général de la Fédération bancaire française et délégué général de l’Association française des marchés financiers (AMAFI), vient de publier “Pour un grand retournement politique. Faces aux impasses du paradigme actuel“. Nous l’avons interrogé : Dans votre ouvrage, vous proposez “un grand retournement politique” sur les bases de la pensée classique. Un paradigme, c’est ce qui structure la pensée collective et son expression publique. C’est pourquoi je plaide dans ce livre pour le retour à la pensée politique classique, celle d’Aristote et de Thomas d’Aquin. Au vu de l’immigration, ne pensez-vous pas que nous risquons de sortir du paradigme actuel pour tomber aux mains de l’islam ? C’est un des points les plus inquiétants de notre situation actuelle. Deux choses sont vraies en même temps, que la pensée classique a toujours soulignées.
August 22 was Earth Overshoot Day In 8 Months, Humanity Exhausts Earth's Budget for the Year August 20 is Earth Overshoot Day 2013, marking the date when humanity exhausted nature’s budget for the year. We are now operating in overdraft. For the rest of the year, we will maintain our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere. Just as a bank statement tracks income against expenditures, Global Footprint Network measures humanity’s demand for and supply of natural resources and ecological services. In 1993, Earth Overshoot Day—the approximate date our resource consumption for a given year exceeds the planet’s ability to replenish—fell on October 21. Earth Overshoot Day, a concept originally developed by Global Footprint Network partner and U.K. think tank new economics foundation, is the annual marker of when we begin living beyond our means in a given year.

Les livres blancs | La plateforme de référence du livre blanc et de l'ebook The Anthropocene | An Introduction Every living thing affects its surroundings. But humanity is now influencing every aspect of the Earth on a scale akin to the great forces of nature. There are now so many of us, using so many resources, that we’re disrupting the grand cycles of biology, chemistry and geology by which elements like carbon and nitrogen circulate between land, sea and atmosphere. Our species’ whole recorded history has taken place in the geological period called the Holocene – the brief interval stretching back 10,000 years. Probably the best-known aspect of our newfound influence is what we’re doing to the climate. These developments are all connected, and there’s a risk of an irreversible cascade of changes leading us into a future that’s profoundly different from anything we’ve faced before. The Anthropocene is a decisive break from what came before. Whenever the new epoch started, we’re living in it now. More on the origin of the concept:International Geosphere-Biosphere Programme
