• Louisiana energy companies sued over destruction of New Orleans' wetlands

    The Louisiana oil and gas industry has dredged more than 10,000 miles of canals through the state’s wetlands, causing the destruction of natural buffers and barriers which, in the past, had moderated the impact of hurricanes and protected New Orleans from severe storms. The Army Corps of Engineers has embarked on a $14.6 billion plan to undo some of the damage caused by the energy companies. The plan consists of levee improvement, wetland restoration, and land reclamation to make New Orleans better protected in the face of rising seas and more frequent and severe extreme weather events. The Southeast Louisiana Flood Protection Authority East (SLFPAE) has filed suit against 94energy companies,asking the court to order the companies to do their part to correct the problem they have caused.

  • U.S. power plants, utilities face growing cyber vulnerability

    American power plants and utility companies face a growing cyber vulnerability. No U.S power plant has so far suffered a significant cyberattack, even if small-scale attacks are nearly constant, but experts say preventative actions must be taken to ensure safety. Utilities provide services which, if disrupted for long periods of time, may result in economic chaos and may even lead to social unrest.

  • Heat waves to become more frequent, severe

    Climate change is set to trigger more frequent and severe heat waves in the next thirty years regardless of the amount of carbon dioxide (CO2) we emit into the atmosphere, a new study has shown. In the first half of the twenty-first century, these projections will occur regardless of the amount of CO2 emitted into the atmosphere. After then, the rise in frequency of extreme heat waves becomes dependent on the emission scenario adopted.

  • Breakthrough fuel cell technology: the future of electricity generation

    We currently rely upon an increasingly vulnerable electrical grid to provide the energy we need. The best way to decrease that vulnerability is through distributed energy, that is, by making our own energy on-site. A breakthrough fuel cell technology promises to provide always-on electricity to businesses, homes, and eventually automobiles, at about one-tenth the cost and one-tenth the size of current commercial fuel cell systems. The technology allows people to generate their own electricity with a system nearly impervious to hurricanes, thunderstorms, cyberattacks, derechos, and similar dangers, while simultaneously helping the environment.

  • NSA revelations hobble pursuit of a comprehensive cyberdefense initiative

    NSA director General Keith Alexander has proposed a digital version of Ronald Reagan’s space-based Star Wars missile defense program, which Reagan unveiled in 1983. In Alexander’s vision, when a cyberattack is launched at the United States, the defense system would intercept and thwart the attack before it caused any damage. Intercepting a cyberattack would require the NSA to tap, track, and scan all cyber traffic entering the United States. The technology needed to intercept cyberattacks, however, is strikingly similar to the technology the NSA uses for the types of surveillance Snowden exposed. Post-Snowden, it is doubtful that the administration would pursue a comprehensive cyberdefense initiative, or that lawmakers would accept it.

  • U.S. nuclear reactors vulnerable to terrorist attack: study

    More than ten years after the 9/11 hijackers considered flying a fully loaded passenger jet into a Manhattan area nuclear reactor, U.S. commercial and research nuclear facilities remain inadequately protected against two credible terrorist threats — the theft of bomb-grade material to make a nuclear weapon, and sabotage attacks intended to cause a reactor meltdown. A new report finds that none of the 104 commercial nuclear power reactors in the United States is adequately protected — but among the most vulnerable are eleven reactors in California, Connecticut, Florida, Maryland, Massachusetts, Missouri, New York, North Carolina, Texas, and Virginia. One of these reactors, on the grounds of the National Institute of Standards and Technology (NIST), is among the three research reactors fueled with bomb-grade uranium, and is located in the Washington, D.C. suburb of Gaithersburg, less than twenty-five miles from the White House.

  • Bacteria in drinking water are essential to keeping it clean

    Researchers point the way to more sophisticated and targeted methods of ensuring our drinking water remains safe to drink, while still reducing the need for chemical treatments and identifying potential hazards more quickly.

  • U.S. nuclear facilities vulnerable to terrorist attack: study

    Some U.S. nuclear facilities are inadequately protected against theft of weapons-grade materials and sabotage by terrorists. Terrorist attacks on vulnerable nuclear facilities could trigger a meltdown or lead to a diversion of bomb-grade uranium. The danger is far from hypothetical since the 9/11 hijackers are known to have considered flying a passenger jet into a U.S. nuclear reactor before they settled on the World Trade Center as their main terror target.

  • Site of proposed Los Angeles skyscrapers may contain active seismic fault

    Officials at New York-based Millennium Partners have agreed to dig a trench on a site proposed for two towers, thirty-nine and thirty-five stories tall, flanking the iconic Capitol Records building in Los Angeles. Opponents of the project say there is an active seismic fault under the planned location for the two towers, and the developer says the trench will allow geologists to see whether or not it would be safe to build the towers on the proposed site. Critics say that a panel of neutral experts, led by state officials, should do the geological investigation.

  • Better approach toward projecting, planning for rising sea levels on a warmer Earth

    More useful projections of sea level are possible despite substantial uncertainty about the future behavior of massive ice sheets, according to Princeton University researchers. The researchers present a probabilistic assessment of the Antarctic contribution to twenty-first century sea-level change. Their methodology folds observed changes and models of different complexity into unified projections that can be updated with new information. This approach provides a consistent means to integrate the potential contribution of both continental ice sheets — Greenland and Antarctica — into sea-level rise projections.

  • Bolstering national grid resilience as extreme weather events intensify

    Between 2003 and 2012, an estimated 679 widespread power outages in the United States occurred due to severe weather. A recent Congressional Research Service study estimates the inflation-adjusted cost of weather-related outages at $25 to $70 billion annually. A new White House report says that grid resilience is increasingly important as climate change increases the frequency and intensity of severe weather.

  • Groundwater in Vietnam threatened by a new source of arsenic

    In Southern Asia, an estimated 100 million people have been exposed to risks from groundwater contaminated with naturally occurring arsenic. The tainted water, used for drinking, agriculture, and industry, has resulted in a variety of serious health risks, including cancer. “Dig deep” to avoid naturally occurring arsenic contamination has been promoted as an answer to obtaining safe water in South Asia, but arsenic has been found in numerous deep wells drilled in the Mekong Delta region of southern Vietnam.

  • Safety engineers welcome Obama’s chemical facility safety Executive Order

    The American Society of Safety Engineers (ASSE) said it supports President Obama’s Executive Order to improve federal agency coordination of U.S. chemical facility safety and security oversight. The ASSE notes that while the causes of each chemical incident are unique and require careful investigation to help ensure similar incidents do not reoccur, common to every incident are the often overlapping and sometimes confusing layers of regulatory responsibility over facilities where potentially harmful chemicals are produced or stored.

  • Small modular reactors (SMEs) a “poor bet” to revive U.S. nuclear renaissance: report

    A shift to small modular reactors (SMRs) is unlikely to breathe new life into the troubled U.S. nuclear power industry, since SMRs will likely require tens of billions of dollars in federal subsidies or government purchase orders, create new reliability vulnerabilities, as well as concerns in relation to both safety and proliferation, according a report issued last week.

  • A 34-story wooden skyscraper to be built in Stockholm

    A Swedish architectural form is building a 34-story wood skyscraper in downtown Stockholm. Solid wood will be the predominant material in the building’s pillars and beams, while inside the apartments, walls, ceilings, fittings and window frames will be also constructed of wood.The firm says that wood is not only cheaper than either steel or concrete, but is also more fire resistant than both. This is due to 15 percent of wood mass being water, which will evaporate before the wood actually burns. In addition, logs get charred which protects the core.
