The 10 Best TED Talks of 2011 Watching videos online is usually considered fun, but generally a waste of time. Not so with TED videos, which are uniformly interesting, educational, inspiring, and enjoyable. If you haven't spent much time (or any) checking out TED videos, you should – and to help with that, I've compiled what seem to be the very best 10 TED videos of 2011. It was a grueling task, combing through the cream of the crop on the TED site, but somebody had to do it. Some of the talks may have been filmed prior to 2011 but all of the talks here were posted in 2011. Unless you were lucky enough to attend the TED event in question, it's still new to you. How I Became 100 Artists You don't need to be an artist to appreciate Shea Hembrey's "How I became 100 artists," but if you are it's even more amazing. A Modern Take on Piano, Violin, Cello If music is more your thing, then the "Modern Take on Piano, Violin, Cello" entry from the Ahn Trio is a must-watch (and listen). 3 Things I Learned While My Plane Crashed
Le négationnisme climatique Chaque mois paraît dans le monde un ouvrage niant soit le réchauffement, soit ses causes humaines, soit sa gravité. On explique même que ce réchauffement serait une chance pour l’humanité en permettant d’accéder à des ressources jusque-là inexploitées (pétrole en Alaska, agriculture en Sibérie, nouvelles routes maritimes dans le Grand Nord, etc.). Chaque jour des dizaines d’articles expliquent aussi que la science aura de toute façon une réponse au problème du réchauffement planétaire. D’ici à 2100, nous nous dirigeons très probablement vers une hausse globale des températures de +3°C, voire +4°C à la surface de la terre. Le défi à relever est immense. Ce livre est fondé sur une enquête de plusieurs années qui a conduit Florence Leray à lire cette presse, à fréquenter ces réseaux, etc. Le négationnisme climatique, Florence Leray, éditions Golias, janvier 2011, Préface Paul Ariès, avant-propos de Pascal Picq et épilogue de Jean Jouzel. 15 euros.

Some People's Climate Beliefs Shift With Weather - The Earth Institute, Columbia University Study Shows Daily Malleability on a Long-Term Question Social scientists are struggling with a perplexing earth-science question: as the power of evidence showing manmade global warming is rising, why do opinion polls suggest public belief in the findings is wavering? Part of the answer may be that some people are too easily swayed by the easiest, most irrational piece of evidence at hand: their own estimation of the day’s temperature. In three separate studies, researchers affiliated with Columbia University’s Center for Research on Environmental Decisions (CRED) surveyed about 1,200 people in the United States and Australia, and found that those who thought the current day was warmer than usual were more likely to believe in and feel concern about global warming than those who thought the day was unusually cold. A new paper describing the studies appears in the current issue of the journal Psychological Science. The other authors are Eric J.
Welcome | Copenhagen Consensus Center Two degrees is out of reach | Mark Lynas This is the worrying news coming from the latest-generation of climate modelling efforts, just published in Geophysical Research Letters (abstract) by a Canadian team of scientists. The team use an Earth system model, fired up with a new generation of carbon emissions scenarios, to conclude that even limiting the 2100 temperature rise to 2.3C above pre-industrial would require “an immediate and rapid ramp down of emissions, followed by negative emissions (sequestration) in the later half of this century”. As for the goal of holding “the increase in global average temperature below 2C above pre-industrial levels”, well, to get onto that trajectory we would have to take global emissions “down to zero immediately”, because the allowable cumulative carbon budget associated with that temperature target has already been emitted. Whoops! Can we come back to this in four years?
Copenhagen Consensus 2012 | Copenhagen Consensus Center The third Copenhagen Consensus was a year-long project involving more than 65 researchers tasked with setting priorities among a series of proposals to confront ten great global challenges. A panel of economic experts, comprising some of the world’s most distinguished economists, was invited to consider these issues. The ten Assessment Papers, commissioned from acknowledged authorities in each area of policy, included nearly 40 proposals for the panel’s consideration. During the conference the panel examined these proposals in detail. Fighting malnourishment should be the top priority for policy-makers and philanthropists The Expert Panel was presented with nearly 40 investment proposals designed by experts to reduce the challenges of Armed Conflict, Biodiversity Destruction, Chronic Disease, Climate Change, Education Shortages, Hunger and Malnutrition, Infectious Disease, Natural Disasters, Population Growth, and Water and Sanitation Shortages.
{sciences²} - TERRE > Climat : le CNRS répond à Claude Allègre Livre Cnrs Du peuple, la justice est lente, Elle est lente, mais elle vient !, dit la chanson (1). La réponse du CNRS à Claude Allègre est du même acabit. Elle est venue… un an après. Sous la forme d’un pavé collectif - signé de 120 scientifiques - titré sans aucune volonté polémique : «Le climat à découvert. Outils et méthodes en recherche climatique.» Hier matin, au siège du navire amiral de la science française, le Président du CNRS, Alain Fuchs, se déclarait «très content» de tenir cet ouvrage en main. Bref, la présentation officielle de ce livre a failli tourner au grand comique, avec concours de chochoterries pour ne pas nommer l’ancien ministre Claude Allègre et Vincent Courtillot, l’ex-directeur de l’Institut de physique du Globe de Paris. En avril 2010, Alain Fuchs prend deux décisions. Cet audit, conduit par Catherine Jeandel et Remy Mossery s’est appuyé sur l’expertise du Comité, Pour mémoire, parmi les notes du blog consacrées à cette affaire :
Bjorn Lomborg's Dirty Little Math | CleanTechnicaCleanTechnica Cars Published on March 17th, 2013 | by NRDC By Max Baumhefner A Wall Street Journal Op-Ed by Bjorn Lomborg, “Green Cars Have a Dirty Little Secret,” argues that even though driving on electricity emits half as much pollution as driving on gasoline, it never makes up for the additional energy it takes to build electric cars. Lomborg’s argument rests on the reasoning included in this sentence: “If a typical electric car is driven 50,000 miles over its lifetime, the huge initial emissions from its manufacture means the car will actually have put more carbon-dioxide in the atmosphere than a similar-size gasoline-powered car driven the same number of miles.” The premise that the typical electric car will only be driven 50,000 miles is fanciful. Lomborg also claims that cars charged with electricity made from coal are dirtier than gasoline vehicles. And that’s today. Max Baumhefner is an attorney, outdoor enthusiast, and a bread baker.
