Earth Sciences RSS FeedsPolitical leaders play key role in how worried Americans are by climate change - (Ohio State University) More than extreme weather events and the work of scientists, it is national political leaders who influence how much Americans worry about the threat of climate change, new research finds. In a study of public opinion from 2002 to 2010, researchers found that public belief that climate change was a threat peaked in 2006-2007 when Democrats and Republicans in Congress showed the most agreement on the issue....Feed Source: www.eurekalert.org What drives public opinion on climate change? - (Springer) The researchers reveal that the driving factor that most influences public opinion on climate change is the mobilizing efforts of advocacy groups and elites. The study conducted an empirical analysis of the factors affecting US public concern about the threat of climate change between January 2002 and December 2010. The five factors that were examined were extreme weather events, public access to accurate scientific information, media coverage, elite cues and movement/countermovement advocacy.... New methodology assesses risk of scarce metals - (Yale University) Yale researchers have developed a methodology for governments and corporations to determine the availability of critical metals, according to a paper in Environmental Science & Technology.... Established journal Evolutionary Applications to publish under open-access model - (Wiley-Blackwell) Wiley-Blackwell, the scientific, technical, medical and scholarly publishing business of John Wiley & Sons Inc., today announced that Evolutionary Applications has joined the Wiley Open Access publishing program. All newly published articles in the journal will be open access and free to view, download and share for non-commercial use.... Tree rings may underestimate climate response to volcanic eruptions - (Penn State) Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change because large enough temperature drops lead to greatly shortened or even absent growing seasons, according to climate researchers, who compared tree-ring temperature reconstructions with model simulations of past temperature changes.... Land-cover changes do not impact glacier loss - (University of Innsbruck) A new study shows that land-cover changes, in particular deforestation, in the vicinity of glaciers do not have an impact on glacier loss. However, the study, in which Innsbruck climate researcher were directly involved, also shows that deforestation decreases precipitation in mid elevation zones, which affects the quality of life of the population living in the surrounding areas. The study is published online in Nature Climate Change on Feb. 5 2012.... University of Miami student Bignami among 5 Guy Harvey Scholarship recipients - (University of Miami Rosenstiel School of Marine & Atmospheric Science) University of Miami Rosenstiel School of Marine & Atmospheric Science graduate student Sean Bignami received a Guy Harvey Ocean Foundation scholarship for his studies of how the changing chemistry of marine waters as a result of ocean acidification might affect the early development of large marine fish.... AIBS names emerging public policy leaders - (American Institute of Biological Sciences) The American Institute of Biological Sciences has selected two graduate students to receive the 2012 AIBS Emerging Public Policy Leadership Award.

Castaway lizards offer new look at evolutionary processes - (National Science Foundation) Biologists who released lizards on tiny uninhabited islands in the Bahamas have uncovered a seldom-observed interaction between evolutionary processes.Jason Kolbe, a biologist at the University of Rhode Island -- along with colleagues at Duke University, Harvard University and the University of California, Davis -- found that the lizards' genetic and morphological traits were determined by both natural selection and a phenomenon called the founder effect.... Global extinction: Gradual doom is just as bad as abrupt - (University of Cincinnati) Around 250 million years ago, most life on Earth was wiped out in an extinction known as the "Great Dying." A team led by University of Cincinnati geologist Thomas J. Algeo finds that the end came slowly from thousands of centuries of volcanic activity.... Southampton enters research agreement with the Crown Estate - (University of Southampton) The University of Southampton has entered into a research agreement with the Crown Estate to provide specialist expertise to projects involving the seabed and near surface geology of UK waters.... Sediments from the Enol lake reveal more than 13,500 years of environmental history - (FECYT - Spanish Foundation for Science and Technology) A team of Spanish researchers have used different geological samples, extracted from the Enol lake in Asturias, to show that the Holocene, a period that started 11,600 years ago, did not have a climate as stable as was believed.... Parasites or not? Transposable elements in fruit flies - (University of Veterinary Medicine -- Vienna) The problem of parasitism occurs at all levels right down to the DNA scale. Genomes may contain up to 80 percent "foreign" DNA but details of the mechanisms by which this enters the host genome and how hosts attempt to combat its spread are still the subject of conjecture. Important new information comes from the group of Christian Schlötterer at the University of Veterinary Medicine, Vienna. The findings are published in the prestigious journal PLoS Genetics.... Batchelor Foundation challenge grant to support helicopter purchase - (University of Miami Rosenstiel School of Marine & Atmospheric Science) The University of Miami's Rosenstiel School of Marine & Atmospheric Science announced that it has received a challenge grant for $700,000 from the Miami-based Batchelor Foundation to support its exploration research efforts. The funds will be applied toward the acquisition of a helicopter outfitted with a suite of scientific equipment that will serve as the basis for a one-of-a-kind platform for environmental observations at the School.... A battle of the vampires, 20 million years ago? - (Oregon State University) They are tiny, ugly, disease-carrying little blood-suckers that most people have never seen or heard of, but a new discovery in a one-of-a-kind fossil shows that "bat flies" have been doing their noxious business with bats for at least 20 million years.... NASA satellites see wind shear battering Tropical Depression Iggy - (NASA/Goddard Space Flight Center) NASA satellites have watched as wind shear has torn Cyclone Iggy apart over the last day. NASA infrared satellite imagery showed that Iggy's strongest thunderstorms have been pushed away from the storm's center and visible imagery shows the storm is being stretched out. Iggy is weakening and heading for a landfall between Geraldton and Perth.... 'First light' taken by NASA's newest CERES instrument - (NASA/Goddard Space Flight Center) The doors are open on NASA's Suomi NPP satellite and the newest version of the Clouds and the Earth's Radiant Energy System (CERES) instrument is scanning Earth for the first time, helping to assure continued availability of measurements of the energy leaving the Earth-atmosphere system.... Scientists coax shy microorganisms to stand out in a crowd - (University of Washington) Scientists have advanced a method that allowed them to single out a marine microorganism and map its genome even though the organism made up less than 10 percent of a water sample teeming with many millions of individuals from dozens of identifiable groups of microbes....

WHOI scientists will install first real-time seafloor earthquake observatory at Cascadia Fault - (Woods Hole Oceanographic Institution) A $1 million grant from the W. M. Keck Foundation to scientists at the Woods Hole Oceanographic Institution will fund the first seafloor geodesy observatory above the expected rupture zone of the Pacific Northwest's Cascadia fault -- an offshore, subduction zone fault capable of producing a magnitude 9 earthquake and generating a large tsunami.... Bouquet bargains - (National Evolutionary Synthesis Center (NESCent)) Most creatures face compromises when they reproduce -- the more energy they devote to having lots of babies, the less they can invest in each one. But do the same tradeoffs hold true for plants? Biologists have long assumed that plants with bigger, showier flowers can make fewer of them per plant. But the data don't always hold up, scientists say. A new study by researchers at the National Evolutionary Synthesis Center may help explain why.... New super-Earth detected within the habitable zone of a nearby cool star - (Carnegie Institution) An international team of scientists led by Carnegie's Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star. The star is a member of a triple star system and has a different makeup than our Sun, being relatively lacking in metallic elements. This discovery demonstrates that habitable planets could form in a greater variety of environments than previously believed.... EARTH: Dangerous dust - (American Geological Institute) What would you do if you found out that the roads you drive on could cause cancer? This is the reality that residents face in Dunn County, North Dakota. For roughly 30 years, gravel containing the potentially carcinogenic mineral erionite was spread on nearly 500 kilometers of roads, playgrounds, parking lots, and even flower beds throughout Dunn County....
