In the vast frozen whiteness of the central Arctic, the Polarstern, a German research vessel, has settled into the ice for a yearlong float.
For the past six years, some 140 scientists from five institutions have traveled to the Arctic Circle and beyond to gather field data as part of the Department of Energy-sponsored NGEE Arctic project. This article gives insight into how scientists gather the measurements that inform t...
It’s common knowledge that driving aggressively can dent gas mileage, but it’s difficult to determine exactly how much gas drivers waste. A new study by researchers at the Department of Energy’s Oak Ridge National Laboratory has quantified the impact speeding and slamming on the brakes has on fuel economy and consumption. They found that aggressive behavior behind the wheel can lower gas mileage in light-duty vehicles by about 10 to 40 percent in stop-and-go traffic and roughly 15 to 30 percent at highway speeds. This can equate to losing about $0.25 to $1 per gallon.
Deep stores of carbon in northern peatlands may remain stable despite rising temperatures, according to a team of researchers from several U.S.-based institutions. And that is good news for now, the researchers said. Florida State University ...
Complex oxides have long tantalized the materials science community for their promise in next-generation energy and information technologies. Complex oxide crystals combine oxygen atoms with assorted metals to produce unusual and very desirable properties.
depth, population-based approach to identifying such mechanisms for adaptation, and describes a method that could be harnessed for developing more accurate predictive climate change models. For the U.S. Department of...
Thomas Wilbanks and Benjamin Preston, both of the Climate Change Science Institute (CCSI) at Oak Ridge National Laboratory (ORNL), are among the 309 coordinating lead authors of the Intergovernmental Panel on Climate Change’s (IPCC’s) Working Group II (WG II) report.
Carbon dioxide in the atmosphere may get the lion’s share of attention in climate change discussions, but the biggest repository of carbon is actually underfoot: soils store an estimated 2.5 trillion tons of carbon in the form of organic matter.
On Tuesday, Feb. 18, President Obama unveiled the timing for the next phase of fuel economy regulations for trucks. He delivered his speech at a Safeway store in Maryland.
Former Energy Secretary Steven Chu mixed his Wigner Distinguished Lecture on Feb . 12 with a description of his current research at Stanford and his outlook on energy policy and climate change.
