25 Years of Toxic Right to Know
October 18, 2011 09:52 AM - Andy Soos, ENN
On the 25th anniversary of the law that created the Toxic Release Inventory (TRI), Environmental Protection Agency Administrator Lisa P. Jackson was joined by New Jersey Senators Frank R. Lautenberg and Robert Menendez to celebrate improved transparency and environmental quality since the legislation passed in 1986. TRI was established through legislation authored by Senator Lautenberg and signed into law as part of the Emergency Planning and Community Right-to-Know Act (EPCRA). The measure requires owners of facilities to report annually on the amount of toxic chemicals that have been released into the air, water or land. These facilities are also required to report how they dispose of chemicals that are not released into the environment.

It has often and continually debated on how much the level of the sea rise in the next few decades and centuries. Sea level changes is actually old hat and has been happening (up and down) for millenia. New research from several international research groups, including the Niels Bohr Institute at the University of Copenhagen provides independent consensus that IPCC predictions of less than a half a meter rise in sea levels is around 3 times too low. The new estimates show that the sea will rise approximately 1 meter in the next 100 years in agreement with other recent studies. The results have been published in the scientific journal, Geophysical Research Letters.
Solar Power and Which Roof to Use
October 17, 2011 12:19 PM - Andy Soos, ENN
A roof is more than a way of keeping the rain off. Nowadays many people think of a roof as a place to put solar panels to collect all of that free sunshine. The problem is that not all roofs are created equal. Scientists from the University of Gothenburg have launched a tool that uses the actual conditions to determine the maximum possible magnitude of solar incidence (and implied the maximum amount of time in shadow)- in a whole town, a neighborhood, or a particular roof. The scientists have surveyed Gothenburg in a pilot project.
Vermont Experiments in Cow Power

A recent case study in the State of Vermont suggests that deriving electricity from cow manure may be economically feasible. This small and largely agrarian state has no shortage of cows and dairy farms. It is conceivable that with the proper commitment from farmers, utilities, and government agencies, cow power could be a central part of the Vermont electric grid. The seven-year study was conducted by six dairy farms, and produced 12 million kilowatt hours of electricity per year.
Earthquakes in Mid America
October 17, 2011 08:46 AM - Andy Soos, ENN
Between Little Rock, Ark., and Memphis, Tenn., scientists have found evidence of an earthquake source capable of magnitude 7 or greater earthquakes located at the southwestern end of the ancient Reelfoot Rift. This is the same geologic structure that hosts the New Madrid seismic zone which is responsible for the major earthquakes that occurred in the midcontinent almost 200 years ago. The geologic proof includes large, visible sand blows formed by strong ground shaking, and subsurface geophysical imaging of faulting nearby. Field observations and radiocarbon dating suggest that the sand blows formed as the result of two to four earthquakes between 4,800 and 10,000 years ago.
Offshore Wind Development Progressing on US East Coast
October 14, 2011 09:21 AM - David A Gabel, ENN
Plans for large commercial-scale wind farms have been on the table for years, but constantly held up by environmental permitting issues, financing concerns, or local objections based on aesthetics. States like New Jersey, Rhode Island, Delaware, and Massachusetts all have offshore wind projects that have yet to commence. At the American Wind Energy Association's annual conference this week, two major offshore wind developers have announced progress in their attempts to build America's first offshore wind farms. Those two companies, Providence, RI-based Deepwater Wind, and Cape May, NJ-based Fisherman's Energy are taking their projects to the next phase.
Hesperia Planum Mystery
October 13, 2011 12:04 PM - Andy Soos, ENN
One of the supposedly best understood and least interesting landscapes on Mars is hiding something that could rewrite the planet’s history. Or not. In fact, about all that is certain is that decades of assumptions regarding the wide, flat Hesperia Planum are not holding up very well under renewed scrutiny with higher-resolution, more recent spacecraft data. Hesperia Planum is a broad lava plain in the southern highlands of the planet Mars. The plain is notable for its moderate number of impact craters and abundant wrinkle ridges. It is also the location of the ancient volcano Tyrrhena Mons (Tyrrhena Patera). The Hesperian time period on Mars is named after Hesperia Planum. The cause of of the mystery is whatcaused the numerous rilles: water or lava.
Virgin Atlantic Airways to Use Industrial Waste as Jet Fuel
October 13, 2011 10:53 AM - David A Gabel, ENN
Always on the cutting edge, Sir Richard Branson, president of Virgin Atlantic, has set his company on a course towards further sustainability. Virgin Atlantic Airways has announced plans to fly commercial routes on a waste-based, synthetic gas fuel rather than typical jet fuel. The reconstituted fuel will produce half the carbon emissions. The technology making this possible was developed by LanzaTech and Swedish Biofuels. Test flights with the new fuel will commence in New Zealand within the next 18 months. The first commercial flights are expected to begin in China by 2014.
Snowball Earth Cause Debated
October 13, 2011 10:39 AM - Andy Soos, ENN
The hypothesis that Earth was completely covered in ice (Snowball Earth) 635 million years may not be so. The atmospheric concentration of carbon dioxide during that period was much lower than previously thought, according to a team of French researchers from the Institut de Physique du Globe de Paris (CNRS/IPGP/Université Paris Diderot), working in collaboration with scientists from Brazil and the U.S. The Snowball Earth hypothesis posits that the Earth's surface became entirely or nearly entirely frozen at least once. Proponents of the hypothesis argue that it best explains sedimentary deposits generally regarded as of glacial origin at tropical paleolatitudes, and other otherwise enigmatic features in the geological record.
Carbon Sequestraion and the Balance of Property Right and the Public Good
October 12, 2011 01:38 PM - Andy Soos, ENN
Carbon sequestration is the capture of carbon dioxide (CO2). This is the process of carbon capture and storage, where carbon dioxide is removed from flue gases, such as on power stations, before being stored in underground reservoirs. There are also natural sequestration processes such as the ocean. Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming. It has been proposed as a way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels. The lack of a settled legal framework that balances private property rights while maximizing the public good ultimately hinders the large-scale commercial deployment of geologic carbon sequestration, according to research by A. Bryan Endres, a professor of agricultural law at the University of Illinois.
