If the Moon Were Only 1 Pixel - A tediously accurate map of the solar system Mercury Venus Earth You Are Here Moon Mars Jupiter Io Europa Ganymede Callisto Saturn Titan Uranus Neptune Pluto(we still love you) That was about 10 million km (6,213,710 mi) just now. Pretty empty out here. Here comes our first planet... As it turns out, things are pretty far apart. We’ll be coming up on a new planet soon. Most of space is just space. Halfway home. Destination: Mars! It would take about seven months to travel this distance in a spaceship. Sit back and relax. When are we gonna be there? Seriously. This is where we might at least see some asteroids to wake us up. I spy, with my little eye... something black. If you were on a road trip, driving at 75mi/hr, it would have taken you over 500 years to get here from earth. All these distances are just averages, mind you. If you plan it right, you can actually move relatively quickly between planets. Pretty close to Jupiter now. Sorry. Lots of time to think out here... Pop the champagne! We're always trying to come up with metaphors for big numbers.
Antonio Stoppani's Anthropozoic || Making the Geologic Now Edited by Etienne Turpin + Valeria Federighi Images Lisa Hirmer Lisa Hirmer, Untitled, from Sudbury Slag, 2012 Introduction The Italian geologist Antonio Stoppani is a remarkable but little known figure in the history of science and the theoretical humanities. Following this siege, Stoppani also participated in subsequent confrontations, but after the Battle of Novara he returned to the seminary as a grammar teacher. In the late 1880s, Stoppani would return to confront his theological roots, publishing Gli intransigent – a book critical of the Catholic Church and its resistance to political and social change – which prompted attacks from L’Osservatore Romano. back to top ↑ First Period of Anthropozoic Era by Antonio Stoppani, translated by Valeria Federeighi, edited by Etienne Turpin + Valeria Federeghi Images Lisa Hirmer I recall with pleasure the event that we believe opened the vulgar era. It is in this sense, precisely, that I do not hesitate in proclaiming the Anthropozoic era.
Cartographie de l’Anthropocène - Globaïa The Anthropocene: A primer. The Anthropocene. We’re already there. This is our time, our creation, our challenge. Officially, this epoch does not exist. Unofficially however, the term is used more frequently in the scientific literature and, more recently, in publications dedicated to the general public. So, might you ask, what is the Anthropocene? First, the etymology. The term was proposed in 2000 by Paul J. Technically, the Anthropocene is the most recent period of the Quaternary, succeding to the Holocene. The Pleistocene (2.588 Ma to 11.7 Ka) was a tumultuous era, during which more than eleven major glaciations occurred. The Holocene (11.7 ka until about 1800 AD) was a time comparatively smoother in terms of climate variability. We are officially still in the Holocene. We collectively rolled over into a new era, which includes its stakes and challenges but also its opportunities and great qualities. Here is the definition more or less impressionistic we propose for the Anthropocene:
Alive | The Incredible Shrinking Humans Arne Hendriks « The Incredible Shrinking Man » (« L’Incroyable Homme qui rétréci ») est un projet de recherches spéculatives qui explore la possibilité de rétrécir l’espèce humaine pour une meilleure adéquation avec la planète. L’être humain a tendance à grandir de génération en génération. Il en résulte que nous avons besoin de plus en plus de ressources, de nourriture, d’énergie et d’espace pour l’espèce humaine. Grandir de 10 % représente une augmentation de 33 % du poids, et donc une augmentation considérable en besoins matériels. « The Incredible Shrinking Man » propose de ramener l’Homme à 50 cm : il utiliserait alors entre 2 % et 5 % des ressources naturelles dont il a actuellement besoin. « The Incredible Shrinking Man » propose de ramener l’Homme à 50 cm : il utiliserait alors entre 2 % et 5 % des ressources naturelles dont il a actuellement besoin. 2013 — Art — Arne Hendriks —
Homepage ::: Planet Under Pressure Distant Oasis How Did Humans First Alter Global Climate? The scientific consensus that human actions first began to have a warming effect on the earth's climate within the past century has become part of the public perception as well. With the advent of coal-burning factories and power plants, industrial societies began releasing carbon dioxide (CO2) and other greenhouse gases into the air. Later, motor vehicles added to such emissions. In this scenario, those of us who have lived during the industrial era are responsible not only for the gas buildup in the atmosphere but also for at least part of the accompanying global warming trend. Now, though, it seems our ancient agrarian ancestors may have begun adding these gases to the atmosphere many millennia ago, thereby altering the earth's climate long before anyone thought. New evidence suggests that concentrations of CO2 started rising about 8,000 years ago, even though natural trends indicate they should have been dropping. Select an option below: Customer Sign In
L'homme tient l'avenir de la Terre dans ses mains: bienvenue dans l'anthropocène Temps de lecture: 14 min Anthropo-quoi? «Anthropocène», terme proposé par Paul Crutzen, chimiste et météorologue néerlandais nobélisé pour ses travaux sur la couche d'ozone, signifie que l'espèce humaine est devenue la principale force géophysique de la Terre, capable de modifier définitivement son environnement. L'impact de ses activités l'emporte en effet, pour la première fois dans l'histoire de notre planète, sur toutes les autres, c'est-à-dire l'ensemble des facteurs naturels. Dans cet anthropocène –du grec anthropos, être humain–, l'homme modifie le climat planétaire ainsi que les grands équilibres de la biosphère, essentiellement par la masse de gaz polluants qu'il produit. L'usine remplace alors le travail agricole et artisanal. Nos colocataires? Bon. La Terre, planète toute riquiqui à l'échelle de l'univers, parmi des milliards d'autres exoplanètes, pourrait bien devenir, par nos regards indifférents, la somme cataclysmique de nos actes. Soyons clair. Notre histoire s'accélère.
Climat : le jet-stream perd le nord ! Le réchauffement de l'Arctique pourrait affecter durablement le "jet-stream" polaire, qui est déterminant pour le climat en Amérique du Nord et en Europe, selon des travaux américains. Cette étude indique que les vents du "jet-stream", qui soufflent d'ouest en est à haute altitude, "s'affaiblissent et ce courant tend de ce fait à s'élargir et à dévier plus facilement de sa trajectoire", a expliqué Jennifer Francis, professeur de climatologie à l'université Rutgers dans le New Jersey. Elle est le principal auteur de cette recherche présentée samedi à la conférence annuelle de l'Association américaine pour l'avancement de la science (AAAS) réunie ce week-end à Chicago. "Quand le jet-stream s'affaiblit - ce qui a été le cas ces deux dernières décennies -, les phénomènes météorologiques ont tendance à durer plus longtemps", a-t-elle dit lors d'une conférence de presse.

The geology of the planet: Welcome to the Anthropocene THE Earth is a big thing; if you divided it up evenly among its 7 billion inhabitants, they would get almost 1 trillion tonnes each. To think that the workings of so vast an entity could be lastingly changed by a species that has been scampering across its surface for less than 1% of 1% of its history seems, on the face of it, absurd. But it is not. Humans have become a force of nature reshaping the planet on a geological scale—but at a far-faster-than-geological speed. A single engineering project, the Syncrude mine in the Athabasca tar sands, involves moving 30 billion tonnes of earth—twice the amount of sediment that flows down all the rivers in the world in a year. Geologists care about sediments, hammering away at them to uncover what they have to say about the past—especially the huge spans of time as the Earth passes from one geological period to another. The carbon cycle (and the global warming debate) is part of this change. The new geology leaves all in doubt
La 'respiración' del planeta en un par de imágenes Fuente: NPR (Pincha para ver en grande) El diseñador John Nelson tomó las imágenes de la NASA y las ha resumido en este impresionante gif que publican en NPR. En él vemos el ciclo anual de vegetación y deshielo, una especie de latido del planeta que muestra los cambios que se producen en el casquete polar ártico cada año. Este latido no siempre ha sido igual, pero desde que tenemos capacidad para observarlo, los científicos se han dado cuenta de que durante el período de contracción veraniego, la parte blanca, es cada vez menor, hasta el punto de que se teme que desaparezca por completo.
