Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the creation of a new index that will measure carbon dioxide emissions from the U.S. electrical power generation sector. The Carnegie Mellon Power Sector Carbon Index will track the environmental performance of U.S. power producers and compare current emissions to historical data collected nationwide for more than two decades. A quarterly press release will inform interested parties of power sector carbon emissions performance trends. In addition, CMU will provide an online resource for a wide variety of power sector emissions data and forecasts.
Flying over the remote during research at the Barnes Ice Cap on Baffin Island in 2009, a Boulder scientist saw dark where there should have been white.
Closer inspection revealed that what Gifford Miller spotted was the remnants of a 1963 geological camp that had been buried for decades by snow and ice. Long-abandoned tents and snowmobiles were being unveiled by melting of the ice cap, and that helped inspire a study that suggests a disturbing climate change signal.
Northern North Dakota – the Souris River, Devils Lake and the northernmost reaches of the Red River – has the greatest risk of major flooding this spring, while moderate flooding is possible over southern Idaho in the Snake River basin, according to NOAA’s Spring Outlook released today.
A research team led by University of Toronto's Faculty of Applied Science & Engineering ‘squashes’ the shape of nanoparticles, enabling inexpensive lasers that emit light in a customized rainbow of colours
Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study by Smithsonian scientists published in the Proceedings of the National Academy of Sciences. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone—a low-oxygen area that snuffs out marine life—rather than by ocean warming or acidification.
International research team warns of mineral supply constraints as demand increases for green technologies
An international team of researchers, led by the University of Delaware’s Saleem Ali, says global resource governance and sharing of geoscience data is needed to address challenges facing future mineral supply.
Specifically of concern are a range of technology minerals, which are an essential ingredient in everything from laptops and cell phones to hybrid or electric cars to solar panels and copper wiring for homes. However, base metals like copper are also a matter of immense concern.
Lamprey are slimy, parasitic eel-like fish, one of only two existing species of vertebrates that have no jaw. While many would be repulsed by these creatures, lamprey are exciting to biologists because they are so primitive, retaining many characteristics similar to their ancient ancestors and thus offering answers to some of life's biggest evolutionary questions. Now, by studying the lamprey, Caltech researchers have discovered an unexpected mechanism for the evolution of the neurons of the peripheral nervous system—nerves outside of the brain and spinal cord.
Extreme weather conditions due to climate change pose a new threat to ageing infrastructure. We need to be better prepared, according to a publication by the OECD's International Transport Forum. The findings of a number of research projects can now be applied worldwide. VTT Technical Research Centre of Finland was the lead author of the report in Finland.
ELECTRIC TRUCKS OFFER all the advantages of electric cars, namely, they’re greener. Trucks are a big source of the noxious emissions linked to smog and climate change. Minimizing the number of stinky, dirty diesels rumbling through town carries obvious public health benefits. But powering delivery trucks, let alone an 18-wheeler, with a big honkin’ battery simply isn’t practical. So engineers are taking another look at a century old solution: Stringing electrical cables over the road.
Chemists at FAU have developed a process in which nitrogen oxides generated during industrial processes can be used in the manufacture of colourants and medicines. Using the method, businesses will in future be able to combine the decontamination of exhaust fumes with the production of new substances.
Nitrogen oxides are a major environmental pollutant. Nitrogen and oxygen compounds are primarily formed during combustion, for example in automobile engines and coal and gas power plants, but also through other thermal and chemical techniques employed by industry. In order to clean these waste gases, the methods of post-combustion capture or catalytic reduction are employed – both of which are relatively complex and are also associated with certain disadvantages. But nitrogen oxides are not just unwanted toxins. In fact, recent research has shown that they can be used in the chemical synthesis of high-value products.
