• Egypt's Internet blackout revives U.S. "kill switch" debate

    Egypt’s five-day shutdown of the Internet has revived debate in the United States over how much authority the U.S. president should have over the Web in the event of a crisis; a bill pending before Congress would give the president the authority to shut down parts of the Internet in the event of a national security crisis such as a sustained enemy cyberattack on the U.S. national grid or financial systems; critics say this is a threat to civil liberties; “It’s not an Internet kill switch,” says one cyber expert; “But you can think about isolating certain domains or certain enterprises; say a big power company gets infected— You say to them, ‘Disconnect yourself before you infect other power companies’; It’s like an avian flu quarantine for the Internet”

  • Minnesota will see major floods in spring

    Meteorologists project major floods in Minnesota this spring; emergency response officials warn that major roadways will likely be closed and are urging residents to immediately purchase flood insurance; officials are also encouraging residents to develop evacuation plans and to begin raising appliances off of basement floors; a third particularly rainy autumn followed by double the average amount of snow is to be blamed for the floods, as excessive snow melt will swell rivers in the spring; last year similar conditions caused rampant flooding and an estimated $28 million in damages

  • California dams plagued by seismic concerns

    Half of Santa Clara County, California’s reservoirs cannot be filled to their full capacity due to seismic concerns; engineering tests revealed that in the event of a major earthquake the dam could slump sending a deadly tidal wave across densely populated communities; seismic retrofit costs to the county’s dam are estimated at $150 million; with the reduced capacity, the county’s dams must be maintained at 67 percent of its total capacity and cannot store more water in preparation for future droughts; the lost capacity could provide water for 280,000 people for a year

  • Megastorm could devastate California, not just earthquakes

    A team of over 100 scientists, engineers, and emergency planners are urging California disaster planning officials to prepare for megastorms; the team projected that a catastrophic megastorm could decimate California with massive landslides and flooding; the findings were based on geological evidence of such powerful storms that occur every 300 years; the last megastorm occurred in 1861 and left the Sacramento Valley an “inland sea”

  • Scientist tackles China's "sinking cities" problem

    A University of Nottingham researcher has been awarded funding to help China prevent human disaster as some of its fastest-growing cities sink under the weight of towering skyscrapers; one example: Shanghai, one of the most densely-populated cities in the world, is sinking at an average rate of between two centimeters to four centimeters a year, putting pressure on underground pedestrian and railway tunnels and building foundations

  • New York State prepares for sea level rise

    More than 62 percent of New York State’s population lives in marine coastal counties; sea level in the Lower Hudson Valley and Long Island is projected to rise two to five inches by the 2020s, increasing 12 to 23 inches by the end of the century (up to 55 inches by the end of the century if accelerated polar ice melt occurs); New York Harbor has already experienced an increase in sea level of more than 15 inches in the past 150 years, with harbor tide gauges showing a rise of between four and six inches since 1960

  • Aussies flee more flooding

    Flood water in northern Australia now cover an area larger than Germany and France combined; in addition to Queensland, large parts of the state of Victoria are now under water; around sixty towns across an area larger than Denmark to the north-west of the state capital, Melbourne, have been hit by floods as heavy rain from recent weeks makes its way across broad floodplains to the Murray River; the estimated damage in hard-hit Queensland now stands at US$19.8 billion

  • Rising sea waters threaten North Carolina's delicate coastline

    A North Carolina science panel is predicting the sea level will rise by one meter by 2100; this means about 2,000 square miles of coastline that is a meter or less above water is at risk; on that land is some of the state’s most expensive real estate that economists say is worth a total of almost $7 billion

  • Mexico City's sinking is worsening

    Scientists are alarmed by the extent to which Mexico City has sunk; over the last 100 years, parts of the city have sunk as much as forty-two feet — and sections of the city sink as much as eight inches a year; the sinking has caused the city’s sewage system to back up resulting in dangerous floods; the sinking is the result of water being pumped from the aquifer directly below the city more quickly than it is being replenished; Mexico City is built in the middle of Lake Texcoco, which has been drained

  • AVERT evaluates vulnerabilities, assess solutions

    Ares Corp.’s AVERT software tool analyzes the security of a given facility in order to understand vulnerabilities and evaluate the effectiveness of existing and proposed countermeasures; it aims to help users develop security solutions within budget and security constraints; traditional vulnerability analyses rely on subjective judgment and checklists, but the AVERT software applies probabilistic algorithms and Monte Carlo analysis to identify and quantify security vulnerabilities by simulating user-defined attacks against the site to determine worst case paths one or more intruders might take to specific targets

  • Brisbane under water

    Brisbane, a city of two million and Australia’s third largest, is flooded; roads are inundated, railway lines have been cut, and sewage is spreading into the waters; dozens of suburbs are under three meters of waters, with some factories and homes only visible by their roofs; more than 100,000 properties had their power cut as a precaution against flooding of electricity substations; the worst affected area was the town of Toowoomba, west of Brisbane, where residents described an 8-meter “instant inland tsunami” ripping through the streets on Monday; the flood zone in northern Australia now covers are larger than Germany and France combined

  • Aussie "inland tsunami" now threatens Brisbane

    The flood zone in northern Australia covers an area larger than France and Germany combined; incessant rain and wide-spread floods have destroyed infrastructure and severely hampered economic activity; the worst is yet to come: Brisbane river has broken its banks, sparking fears that the city — Australia’s third largest and home to two million people - will be flooded by Thursday; public health experts fear that outbreaks of Ross river virus — a debilitating disease transmitted by mosquitoes, which is endemic in Queensland — will increase

  • World Bank: Coastal cities in Asia face devastating floods

    Thirteen of the twenty largest cities in the world are located on the coast, with more than a third of the world’s population living within 100 miles of a shoreline; a World Bank report finds that Asia’s major coastal cities will experience more devastating floods; damage due to flooding could be as high as 6 percent of regional GDP in 2050; developing cities will be most heavily affected; the report urges the threatened cities immediately to begin developing and implementing long-term plans to harden critical infrastructure to withstand and mitigate the effects of increased flooding

  • New spacecraft to help break the climate debate gridlock

    NASA plans to settle the climate debate with a fleet of Earth-orbiting spacecraft keeping tabs on the planet’s changing climate; the fleet has two tasks: first: take the total amount of energy coming to Earth from the sun, subtract what gets reflected back or re-radiated from particles in the atmosphere, and see what you have left; if more energy is coming in than going out, it is getting hotter; second: figure out what fraction of these atmospheric particles stems from natural phenomena, such as wind-blown dust and volcanic eruptions, and what is coming from things we can control — our industrial processes, business pursuits, and recreational pass-times
