Here are some stunning news. To TreeHugger : ” Scientists have just completed the most accurate tally of the planet’s species yet (though the projection still has a pretty healthy margin of error). The magic number?” ” 8.7 million, according to the study, which was recently published in the journal PLoS Biology. But the amazing …
To the Independent : ” Climate researchers from Britain, the US (…) have formed a new alliance that aims to investigate exceptional weather events to see whether they can be attributable to global warming caused by greenhouse gas emissions. ” ” They intend to assess each unusual event in terms of the probability that it …
To Climate Progress : ” Is the “Global Weirding” of 2010 and 2011 the new normal? (…) Any one of the extreme weather events of 2010 or 2011 could have occurred naturally sometime during the past 1,000 years. “ ” But it is highly improbable that the remarkable extreme weather events of 2010 and 2011 …
This is the title of an interesting article at GreenTech Media. Here are some essential quotes of it : ” Hydrogen. In green technology circles, just mentioning the word is enough to start an argument. “ ” Hydrogen could become a ubiquitous source of electricity and heat, say advocates. Plus, it’s somewhat prevalent. Hydrogen remains …
To CleanTechies : ” According to a new NASA-funded study, Greenland and Antarctic ice sheets are losing mass at a much faster rate than previous model forecasts have predicted. “ ” Results suggest that the ice sheets, found only in Antarctica and Greenland, are melting faster than mountain glaciers and ice caps and are poised …

It’s a well known fact, the production of electricity via traditional coal and natural gas burning plants and in a lesser way nuclear reactors is vastly inefficient. But this might change soon thanks to scientific research. To Ecogeek : ” Researchers (…) are developing a new gas turbine to increase the efficiency of conventional electrical …

According to the Canadian magazine Corporate Knights : ” If the concept of a sustainable city sounds like a paradox, that’s because it is, according to physicist Geoffrey West.” ” Ironically, because of their urban “metabolism,” cities require only 85 per cent of the resources necessary to double in size, and they’re more energy efficient …
It made the headlights last week on practically all environmental websites. The hidden costs – the negative externalities if you prefer – of coal are of 500 billion Dollars per year for the United States alone. Yes, you read it right : burning coal costs the country half a trillion dollar on health costs, premature …

As CleanTechnica recently noted : ” A serious challenger has emerged to take on graphene’s title as the miracle material of the 21st century, and that is a common, silvery looking mineral called molybdenite. (…) The lead researcher asserts that compared to conventional silicon transistors, a molybdenite transistor would use about 100,000 times less energy …
Sometimes a short video does better at explaining things than a long text. This is again the case with a video showing the five-year average global temperature anomalies from 1880 to 2010. Using data collected by the NASA’s Goddard Institute for Space Studies, the US National Climatic Data Center, the Japanese Meteorological Agency and the Met …
