Geography professor Bruce Rhoads and geology professor Jim Best were conducting research where the Wabash River meets the Ohio River in the summer of 2008 when they heard about a new channel that had just formed, cutting off a bend in the winding Wabash just upstream from the confluence. That serendipity gave the researchers a rare view of a dynamic, little-understood river process that changed the local landscape and deposited so much sediment into the river system that it closed the Ohio River.
Global emissions of carbon dioxide (CO2) increased by 45 percent between 1990 and 2010, and reached an all-time high of 33 billion tons in 2010. Increased energy-efficiency, nuclear energy and the growing contributions of renewable energy are not compensating for the globally increasing demand for power and transport, which is strongest in developing countries.
On September 11, 2001, as the twin towers of the World Trade Center exploded and collapsed, clouds of dust billowed into the sky and across the city. Photographs from the outskirts show the thick clouds swallowing much of lower Manhattan. Satellite images reveal that the clouds were large enough to be seen from space. Survivors overtaken by the clouds emerged covered in a thick layer of dirt and debris. They reported that the clouds were so dense that they blacked out the sun.
Twelve people were charged yesterday with illegally distributing and selling unregistered and misbranded pesticides from multiple locations in Manhattan. Prosecutors charged two of the 12, Chen Yah Huang and Jai Ping Chen, with federal crimes, and the remaining ten were charged under state statutes
The black smoke that rose from the water’s surface during the controlled burns pumped more than 1 million pounds of black carbon (soot) pollution into the atmosphere, according to a new study published last week by researchers at NOAA and its Cooperative Institute for Research in Environmental Sciences (CIRES) in Boulder, Colo.
The federal and state natural resource trustees estimate that the spill killed 6,849 birds, affected 14 to 29 percent of the herring spawn that winter, oiled 3,367 acres of shoreline habitat and resulted in the loss of more than one million recreational user-days. A result of a multi-governmental effort by federal and state agencies, and municipal governments, the settlement is expected to fully compensate (in addition to previously reimbursed costs) for the natural resources and other damages and costs resulting from the spill.
The report identifies best practices and makes recommendations to help save more lives during future violent tornadoes. Most importantly, the assessment emphasizes that people must be prepared to take immediate action when a warning is issued.
Modifying soybean seed to increase phosphorus content can improve animal nutrition and reduce feed costs and nutrient pollution. However, further research is needed to commercialize this valuable technology.
DOE announces 16 projects supporting activities in 24 states and the District of Columbia to accelerate the adoption of electric vehicles in communities across the nation, and seven additional projects in seven states to help prepare college students for careers designing and building advanced vehicle technologies.
Worldwide energy consumption is projected to grow by 53 percent between 2008 and 2035, with much of the increase driven by strong economic growth in the developing nations especially China and India, according the Energy Information Administration’s International Energy Outlook 2011.
The bill would give algae-based biofuels tax parity while leveling the playing field for all advanced biofuels by expanding the Clean Air Act’s definition of an advanced biofuel.
A chemical manufacturing and distribution facility in South Portland, Maine, faces an EPA fine of up to $151,900 for improper storage of hazardous materials, in violation of federal and state laws.
EPA Region 10 issued final air quality permits to Shell on Sept. 19 for oil and gas exploration drilling in the Alaska Arctic. The permits will allow Shell to operate the Discoverer drillship and a support fleet of icebreakers, oil spill response vessels, and supply ships for up to 120 days each year in the Chukchi Sea and Beaufort Sea Outer Continental Shelf starting in 2012.
Deforestation in the rainforests of West Africa reduces rainfall over the rest of the forest, according to new University of Leeds research published in Geophysical Research Letters. The study shows that changing land use from forest to crop land reduces rainfall over neighboring trees by about 50 percent due to changes in the surface temperature, which affects the formation of rain clouds.
Our most reliable models rely on data acquired through a range of complex measurements. Most of the important measurements - such as ice cover, cloud cover, sea levels and temperature, chlorophyll (oceans and land) and the radiation balance (incoming to outgoing energy) – must be taken from space, and for constraining and testing the forecast models, made over long timescales.
the Energy Department has awarded more than $30 million to 24 universities in 23 states across the country to train undergraduate- and graduate-level engineering students in manufacturing efficiency to help these students become the nation's next generation of industrial energy-efficiency experts.
Gulf War Illness (GWI)—the chronic health condition that affects about one in four military veterans of the 1991 Gulf War—appears to be the result of several factors, which differed in importance depending upon where veterans served during the war, according to a Baylor University study.
The planet’s deep oceans at times may absorb enough heat to flatten the rate of global warming for periods of as long as a decade even in the middle of longer-term warming, according to a new analysis led by the National Center for Atmospheric Research (NCAR).
The new material can store and release hydrogen extremely fast and at low temperatures compared with similar materials, and it's rechargeable. These attributes could make it ideal for use in onboard hydrogen storage for next-generation hydrogen or fuel cell vehicles.
A team of researchers from the Georgia Institute of Technology is using the Aquarius underwater laboratory off the coast of Florida to study how the diversity of seaweed-eating fish affects endangered coral reefs. The research mission, which began Sept. 13, may provide new information to help scientists protect and even restore damaged coral reefs in the Caribbean.
