• Sandy shows need for more effective preparedness, resiliency standards

    The rebuilding efforts following the devastation wreaked by Superstorm Sandy have triggered a discussion over preparedness and resiliency in America’s commercial and residential buildings.Some experts callfor a presidential appointment of a building resilience “’czar”’ with authority to coordinate and seek synergies between public and private sector initiatives.

  • 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.

  • 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.

  • 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.

  • 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.

  • Assessing the risks of global aftershock

    The entire world becomes an aftershock zone after a massive magnitude (M) 7 or larger earthquake — but what hazard does this pose around the planet? Researchers are working to extend their earthquake risk estimates over a global scale, as they become better at forecasting the impact of aftershocks at a local and regional level.

  • Making storm warnings more exact, useful

    The College of Staten Island (CSI)is the home of one of the most powerful mainframe computer systems in the country, an outgrowth of the City University of New York’s (CUNY) Decade of Science initiative. Following August 2011 Hurricane Irene, CSI scientistsset out to use that computing horsepower to generate scientific data hard enough to make the warnings something more than abstract. They fed millions of data points into the supercomputers, turning an admixture of geology, oceanography, climatology, and land surveys into a set of highly specific projections. Then, on 25 October 2012, Superstorm Sandy hit, and the actual water surges could be measured against the surge projections of the CSI model. On street after street, the computer model predicted flooding to within a foot of the actual surges.

  • SkySweeper robot inspects power lines easily, cheaply

    Mechanical engineers invented a robot designed to scoot along utility lines, searching for damage and other problems that require repairs. Made of off-the-shelf electronics and plastic parts printed on an inexpensive 3D printer, the SkySweeper prototype could be scaled up for less than $1,000, making it significantly more economical than the two models of robots currently used to inspect power lines.

  • Next NIST workshop on critical infrastructure cybersecurity framework: Dallas, 11 September 2013

    Registration is now open for the fourth in a series of workshops to bring together representatives from government, industry, and academia to establish a voluntary Cybersecurity Framework which will help reduce risks to critical infrastructure. The workshop will be held 11-13 September 2013, at the University of Texas at Dallas, and will be the final public session before the preliminary framework is formally released later this year.

  • Man-induced quakes to help in building safer, sturdier buildings

    A team led by Johns Hopkins structural engineers is shaking up a building in the name of science and safety. Using massive moving platforms and an array of sensors and cameras, the researchers are trying to find out how well a two-story building made of cold-formed steel can stand up to a lab-generated Southern California quake.

  • Ten-fold increase in frequency of Katrina-magnitude storms this century

    Tropical cyclones arise over warm ocean surfaces with strong evaporation and warming of the air. Since 1923, there has been a Katrina magnitude storm surge every twenty years. Researchers found that 0.4 degrees Celcius warming of the climate corresponds to a doubling of the frequency of extreme storm surges like the one following Hurricane Katrina. If the temperature rises an additional degree, the frequency will increase by 3-4 times, and if the global climate becomes two degrees warmer, there will be about ten times as many extreme storm surges.
