How Hot Is It? All You Need To See Are These Two Maps : The Two-Way The heat wave across much of the nation continues. We could hit 105 degrees on Saturday here in the nation's capital, the National Weather Service says. Washington, D.C., has already tied its record for most consecutive days (eight) with temperatures of 95 degrees or more. And as Wunderground.com writes, "more record-breaking triple-digit heat is expected Friday and Saturday across much of the Midwest and Tennessee Valley." The good news is that things could start to cool in just a few days. "Early next week and even this weekend we'll see rain in Kansas and Nebraska and parts of Texas," forecaster Bruce Sullivan of the National Weather Service, tells USA Today. But what we want to focus on are some incredible statistics and maps from the National Climatic Data Center. First, look at this image showing the number of places where daily maximum temperature records have been broken so far this month. All we can say is, whew! Other numbers about the scorching temperatures:
Après la pluie Ça s'est drôlement rafraîchi aujourd'hui. La pluie va sûrement plus tarder. Mais il a fait bien chaud ces derniers jours. Bin quoi ? Sebastião Salgado, Antarctique, 2005 Draches sacrées le mois dernier, donc. Chaque fois qu'aux temps chauds, il flotte de la sorte, je repense à l'explication fournie par Hervé Le Treut, l'un des plus éminents climatologues français, au cours d'un débat auquel je l'avais invité en septembre 2007, après un précédent été particulièrement humide : "Globalement, un climat plus chaud est un climat plus humide (...). Hé oui, c'est évident. Au mois de mai, il a pu faire 15°C sur le Sud-Ouest avec des pluies entrecoupées d'averses, tandis que c'était canicule et grand ciel bleu en Alsace. Imaginez un peu à quoi ressemblera la météo si ce genre de contrastes se trouve démultiplié, à mesure que le réchauffement global de l'atmosphère s'intensifiera. Mensonges par omissions. Deux mois avant les pluies de mai, ma mère a dû s'esbigner de sa plage favorite, en Gironde.
Global Warming Effects Map - Effects of Global Warming The Big Conf | Avenir Climatique The Big Conf 2 a été la plus grande conférence étudiante de France sur les enjeux énergie/climat en 2014. Cette deuxième conférence nationale a sensibilisé des milliers d’étudiants au travers de dizaines de conférences! L’objectif du projet a été de former les étudiants aux défis auxquels le monde fait face, pour ensuite devenir des acteurs éclairés s’ils le souhaitent. Pour en savoir plus sur ces sujets, rendez-vous sur la section correspondante de notre site . Dans l’optique de la COP 21 qui se déroulera à Paris en 2015, nous avons voulu que les étudiants puissent comprendre ce qu’il s’y joue. Ce rendez-vous majeur pourrait être un moment décisif si une contribution structurée des jeunes se forme autour des décideurs.

Natureza - Bolha de frio no Atlântico Norte desafia aquecimento global Sequência de mapas climáticos mostra persistência do frio no Atlântico Norte (Foto: NOAA) Com o aquecimento global avançando, 2015 tem boas chances de quebrar o recorde de 2014 como ano mais quente da história, mas existe uma região do mundo que desafia essa tendência: uma bolha de frio no Atlântico Norte. Em todos os últimos 12 meses de registro de temperaturas na região logo ao sul da Groenlândia e da Islândia, as temperaturas de superfície registradas ficaram muito abaixo da média histórica, e em alguns casos bateram recordes de frio. O que está acontecendo na região, porém, não é algo que coloque em xeque as previsões de cientistas sobre a mudança climática. Desde março, cientistas têm oferecido evidências de que uma corrente marinha chamada Amoc (Circulação de Revirada do Atlântico Meridional, na sigla em inglês), está se desacelerando. Ciclo desacelerado A Amoc é um braço da chamada rede mundial de “circulação termoalina”, a macroestrutura de fluxo de água nos oceanos.
The Titanic At 100 Years: We're Still Ignoring Warnings, This Time It's Climate Change, Says Director James Cameron By Joe Romm on April 13, 2012 at 12:31 pm "The Titanic At 100 Years: We’re Still Ignoring Warnings, This Time It’s Climate Change, Says Director James Cameron" One century ago this weekend, the great “unsinkable” ship ignored warnings of ice bergs in the vicinity, maintained a high speed, hit an iceberg because it couldn’t change course fast enough, and sank. Most passengers died, in large part because there weren’t enough lifeboats. The New Yorker and the Washington Post have devoted major columns to “Why we can’t let go of the Titanic” and why ”fascination with it seems to be” unsinkable . Director James Cameron offered his own answer this week, in Titanic: The Final Word with James Cameron on National Geographic Channel, which I’ve transcribed here. Part of the Titanic parable is of arrogance, of hubris, of the sense that we’re too big to fail. The tragedy today is not merely that we are ignoring multiple, highly credible warnings of disaster if we stay on our current course.
The Hockey Stick Lives: New Study Confirms Unprecedented Recent Warming Reverses 2,000 Years Of Cooling By Joe Romm "The Hockey Stick Lives: New Study Confirms Unprecedented Recent Warming Reverses 2,000 Years Of Cooling" Last month, we reported on the umpteenth study that confirmed the Hockey Stick. It made clear the rate of global warming since 1900 is 50 times greater than the rate of cooling in the previous 5000 years. That study, Marcott et al, is the most the most comprehensive “Reconstruction of Regional and Global Temperature for the Past 11,300 Years” ever done. Now a team of 78 researchers (from 60 institutions) in the international network PAGES (PAst Global Changes) has “published the most comprehensive reconstruction of past temperature changes at the continental scale” over the past 2000 years. The most coherent feature in nearly all of the regional temperature reconstructions is a long-term cooling trend, which ended late in the nineteenth century. No “worldwide Medieval Warm Period or Little Ice Age.” Here is a key figure from the new study: Related Post:
Warrior Day of Action We are not drowning. We are fighting. March 2nd, 2013 -- Join Us! Pacific Islanders across 15 Pacific Island nations and territories will come together in mass numbers on our islands, mobilising at prominent locations to perform our unique war challenges, songs, and dances. Our Challenge to the world We, the people of the Pacific, spread over hundreds of islands stand united by the Pacific Ocean that connects us. We will continue to fight for our land, our existence, and our identity that is threatened by the impacts of climate change. The world needs to hear the voices of our people! “This is our message to the world that we stand in solidarity against the unwelcomed global reality that is climate change.

Clathrate Un article de Wikipédia, l'encyclopédie libre. Un clathrate, du grec klathron qui signifie fermeture, est un composé d'inclusion formé d'une ou plusieurs molécules d'eau (liées entre elles par des liaisons hydrogène), dites « molécules hôtes », qui emprisonnent une autre molécule de gaz, dite « molécule invitée », dans une sorte de cage moléculaire[1]. Exemples de systèmes de molécules piégées en clathrates. Clathrate couronne d'éther « 18-couronne-6 » piégeant un ion potassium (en violet au centre). Les atomes d'oxygène sont représentés en rouge, ceux de carbone en noir et ceux d'hydrogène en blanc. L'hydrate de méthane, la « glace qui s'enflamme » est le clathrate le plus connu du public. Vocabulaire[modifier | modifier le code] Les clathrates sont aussi appelés host-guest complexes, inclusion compounds ou adducts pour les anglophones ou hydrates quand la molécule hôte est l'eau.

Obama Golfed With Oil Men As Climate Protesters Descended On White House WASHINGTON -- On the same weekend that 40,000 people gathered on the Mall in Washington to protest construction of the Keystone Pipeline -- to its critics, a monument to carbon-based folly -- President Obama was golfing in Florida with a pair of Texans who are key oil, gas and pipeline players. Obama has not shied away from supporting domestic drilling, especially for relatively clean natural gas, but in his most recent State of the Union speech he stressed the urgency of addressing climate change by weaning the country and the world from dependence on carbon-based fuels. "We can choose to believe that Superstorm Sandy and the most severe drought in decades and the worst wildfires some states have ever seen were all just a freak coincidence," Obama said in the speech, last week. "Or we can choose to believe in the overwhelming judgment of science -- and act before it's too late." Carroll is the chairman of CenterPoint Energy, a public utility company based in Houston, Texas.
