Welt steuert auf mindestens drei Grad zu – selbst mit umgesetztem Klimaschutz Kaum noch Chancen fürs Zwei-Grad-Ziel Hat die Menschheit versagt? Die Chance, die Erderwärmung bis 2100 auf zwei Grad oder weniger zu begrenzen, liegt nur noch bei rund fünf Prozent, wie Klimaforscher ermittelt haben. Selbst wenn man sofort alle CO2-Emissionen weltweit stoppen würde – was absolut unrealistisch wäre, steigen die Temperaturen bis 2100 in jedem Falle um 1,3 Grad. Die Aussichten sind nicht rosig: Geht der Klimawandel so weiter, drohen in vielen Teilen der Erde Hitze, Dürren, sintflutartige Regenfälle und überflutete Küstengebiete. Extrapolation aktueller Trends Doch wie realistisch ist dieses Zwei-Grad-Ziel? Ihr Modell basiert auf Daten der letzten 50 Jahre zu Bruttoninlandsprodukt und CO2-Ausstoß pro Wirtschaftseinheit aller Staaten sowie der Tatsache, dass die Weltbevölkerung bis 2100 auf elf Milliarden Menschen wachsen wird, wie die UN prognostiziert. Chance bei fünf Prozent Das Ergebnis: „Unsere Analyse zeigt, dass das Zwei-Grad-Ziel ein ziemliches Best-Case-Szenario ist“, sagt Raftery.

The name says it all. The 2014/2015 movie by that name—“The Film That Environmental Organizations Don’t Want You to See,” according to its website—has uncovered an immense conspiracy between governments and the world’s biggest environmental organizations, to deceive the public about the principal cause of global warming. According to Cowspiracy, the major source of global warming pollution isn’t fossil fuels like coal, oil, and natural gas, as the world’s scientists are telling us. Cows worse than fossil fuels? Central to Cowspiracy’s conspiracy theory is the supposed “fact” that a 2009 study found that 51% of all greenhouse gases are produced by animal agriculture. Since the 51% figure is key to the film’s conspiracy theory, let’s look at the study that it comes from. Inflating livestock emissions by misinterpreting basic biology Changing the impact of methane Why do they do this? And who is in cahoots?
Nouvelles sur le climat | Climate Impact News National geographic Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth’s surface and the human societies spread across it. They also examine how human culture interacts with the natural environment, and the way that locations and places can have an impact on people. Ancient Geographers The term "geography" comes to us from the ancient Greeks, who needed a word to describe the writings and maps that were helping them make sense of the world in which they lived. Of course, the Greeks were not the only people interested in geography. Indeed, mapmaking probably came even before writing in many places. During the Middle Ages, geography ceased to be a major academic pursuit in Europe. In addition to the advances in the Middle East, the Chinese empire in Asia also contributed immensely to geography. Age of Discovery With the dawn of the Age of Discovery, the study of geography regained popularity in Europe.
kelvy bird | surfacing latent, intuited, potential Lo más destacado del Año Europeo del Desarrollo La Unión Europea dedicará 2015 a la ayuda al desarrollo para realzar la importancia de la política de cooperación internacional y el papel fundamental que Europa y sus Estados desempeñan. El Parlamento estará muy implicado en los actos del Año Europeo de Desarrollo, entre los que figuran las Jornadas Europeas del Desarrollo, sesiones temáticas en la comisión de Desarrollo de la Eurocámara y la Expo Mundial de Milán. "El Año Europeo del Desarrollo es una gran oportunidad para implicar a los ciudadanos en el trabajo de las instituciones de la Unión Europea sobre política de desarrollo", aseguró la eurodiputada laborista británica Linda McAvan, Presidenta de la comisión parlamentaria de Desarrollo, en una entrevista publicada en diciembre de 2014 en la web de la Eurocámara. En la nómina de eventos y actividades programados con motivo del Año Europeo del Desarrollo figuran la inauguración oficial del año en Riga (Letonia) este viernes 9 de enero.

The 1847 lecture that predicted human-induced climate change | Leo Hickman | Environment When we think of the birth of the conservation movement in the 19th century, the names that usually spring to mind are the likes of John Muir and Henry David Thoreau, men who wrote about the need to protect wilderness areas in an age when the notion of mankind's "manifest destiny" was all the rage. But a far less remembered American - a contemporary of Muir and Thoreau - can claim to be the person who first publicised the now largely unchallenged idea that humans can negatively influence the environment that supports them. George Perkins Marsh (1801-1882) certainly had a varied career. Here's how Clark University in Massachusetts, which has named an institute in his memory, describes him: Throughout his 80 years Marsh had many careers as a lawyer (though, by his own words, "an indifferent practitioner"), newspaper editor, sheep farmer, mill owner, lecturer, politician and diplomat. In other words, he kept himself busy.
