• New study tracks long-term sea-level rise

    Greenhouse gas emissions up to now have triggered an irreversible warming of the Earth which will cause sea-levels to rise for thousands of years to come, new research has shown; mankind has already committed itself to a sea-level rise of 1.1 meters by the year 3000 as a result of greenhouse gas emissions up to now; this irreversible damage could be worse, depending on the route we take to mitigating emissions

  • Former DHS official says U.S. should go on cybersecurity offensive

    Stewart Baker, the first assistant secretary for policy at DHS under President George W. Bush, has a straightforward theory when it comes to cyber security in the United States: “To prevail in the cybersecurity war, defense is not enough”; not all cuber experts agree with him

  • Experts warn of growing cyber security risks to U.S., criticize Congress’s inaction

    U.S.and Russian cyber experts are trying to scare officials into improving cybersecurity protection in the United Statesand around the world; cyber attacks against critical infrastructure escalate in scope and severity; soon, Kaspersky Lab’s Eugene Kaspersky said: “If previous viruses were like bicycles,then the Stuxnet worm that damaged uranium enrichment centrifuges at the Natanz plant in Iran two years ago would be a plane and the latest programs, dubbed Flame and Gauss,would be space shuttles”

  • Experts trying to determine cause of a giant Louisiana sinkhole

    The earth near Bayou Corne, Louisiana opened on 2 August: a 300-foot-wide sinkhole, with depth varying between 50 and 300 feet, suddenly opened up in an area, and the authorities have been trying to determine whether the sinkhole was caused by the collapse of an abandoned brine mining cavern along the margin of the Napoleonville Salt Dome or by something else

  • Pentagon says privately owned computer networks vulnerable to attack

    Deputy U.S. Defense Secretary Ashton Carter told hundreds of industry executives and military officials at a conference that he  is concerned with the potential of a cyber attack on privately owned U.S. computer networks; “I hope this isn’t one of those situations where we won’t do what we need to do until we get slammed,” Carter said

  • DHS focus on suspicious activity at critical infrastructure facilities

    Federal, state, and local law enforcement let people know that if theytake pictures or notes around monuments and critical infrastructure facilities, theycould be subject to an interrogation or an arrest; in addition to the See Something, Say Something awareness campaign, DHS also has broader initiatives such as the Buffer Zone Protection Program, which teach local police and security how to spot potential terrorist activities

  • Chile relies on new technologies to cope with frequent earthquakes

    Citizens of Chile are used to the ground shaking beneath their feet; in the past two years alone Chile has experienced more than forty earthquakes with magnitudes of six or higher; with so many earthquakes and the potential of thousands dying yearly, Chilean authorities are using new methods to protect their citizens from death and buildings from damage

  • Hurricane Irene polluted Catskills watershed

    The water quality of lakes and coastal systems will be altered if  hurricanes intensify in a warming world, according to a Yale study; researchers found that last summer during Hurricane Irene — the worst storm in the New York area in 200 years — record amounts of dissolved organic matter darkened Catskill waters and affected the Ashokan Reservoir that supplies New York City with drinking water

  • Debate over causes of levee failure during Katrina intensifies

    A court case in which residents of two sections of New Orleans are suing a construction group has put millions of dollars at stake; residents of the Lower 9th Ward and St. Bernard Parish residents claim that Washington Group International (WGI), an Amy Corps of Engineers contractor, removed several buildings and pilings from land along the Industrial Canal as part of a construction plan to expand the canal’s shipping lock, then failed adequately to plug the holes left behind; the holes allowed rainwater from Hurricane Katrina to seep underneath the 14-foot wall, essentially lifting the wall and allowing the areas to be flooded

  • Repair bill for Miami-Dade water and sewage system: $12 billion

    Repairing, replacing, and rebuilding 13,000 miles of old water and sewage pipes and the treatment plants they connect to could cost Miami-Dade County, Florida more than $12 billion dollars over the next fifteen years; this is a staggering amount – made even more so in light of the fact that this is considerably more than the original estimate of $1 billion

  • Dutch test-levee experiment helps strengthen U.S. levees, dams

    In the United States, the national flood-control infrastructure is aging and its structural health is deteriorating; the system comprises more than 5,600 km of levees, and 43 percent of the U.S. population lives in counties with levees designed to provide some level of protection from flooding; some of these levees are as old as 150 years; in 2009, the American Society of Civil Engineers Report Card for America’s Infrastructure gave the condition of the nation’s dams a grade of D, and levees a grade of D-minus; an dam-strength experiment in the Netherland helps engineers collect data to validate new suite of technologies for assessing the health of levees and dams

  • New FERC office to focus on cyber security

    The Federal Energy Regulatory Commission (FERC) has created a new FERC office — Office of Energy Infrastructure Security (OEIS) —  which will help the Commission focus on potential cyber and physical security risks to energy facilities under its jurisdiction

  • Rare Earth metals: Will we have enough?

    Life in the twenty-first century would not be the same without rare Earth metals; cell phones, iPads, laptops, televisions, hybrid cars, wind turbines, solar cells, and many more products depend on rare Earth metals to function; will there be enough for us to continue our high-tech lifestyle and transition to a renewable energy economy? Do we need to turn to deep seabed or asteroid mining to meet future demand?

  • Specialty metals recycling policy needed: experts

    An international policy is needed for recycling scarce specialty metals that are critical in the production of consumer goods; because they are used in small amounts for very precise technological purposes, such as red phosphors, high-strength magnets, thin-film solar cells, and computer chips, recovery can be so technologically and economically challenging that the attempt is seldom made

  • New York unprepared for flooding, sea level rise

    New York City may be a fast paced city of bright lights, sleek attitudes, fashion trends, and some of the best sports teams in the country, but underneath the glitz and glamour is a city which is not prepared for an act of God and which is being threatened by rising sea levels and severe storm flooding; “It’s a million small changes that need to happen,” one expert says
