• Limiting methane emissions would more quickly affect climate than limiting CO2

    When discussing climate change, scientists point to “radiative forcing,” a measure of trapped heat in Earth’s atmosphere from man-made greenhouse gases. The current role of methane looms large, they say, contributing over 40 percent of current radiative forcing from all greenhouse gases. The role of methane as a driver of global warming is even more critical than this 40 percent value might indicate, they note, since the climate system responds much more quickly to reducing methane than to reducing carbon dioxide. The implication is that while it is true that in order to slow, or even reverse, global warming we must limit emissions of both carbon dioxide and methane, it makes more sense to concentrate now on limiting methane emissions because reducing methane emissions would buy society some critical decades of lower temperatures.

  • Behind the Boko Haram headlines, slavery in Africa is the real crisis

    The mass kidnapping of schoolgirls by terrorist group Boko Haram in Nigeria is neither a new nor rare occurrence. Boko Haram has been active in Nigeria for five years and is just the tip of the iceberg when it comes to Africa’s slavery crisis. In Nigeria, there are tens of thousands of people bought and sold every year, according to Africa experts. The majority are children: in 2003, the International Labor Organization estimated that as many as six million Nigerian children had been trafficked at some time in their lives. In Africa as a whole, the scale of the problem is vast and far beyond the resources currently allocated to fight it, let alone sufficient to help victims. Experts estimate that $1.6 billion profit (an amount larger than the GDP of eight African countries last year) derives from African and Middle Eastern slavery annually.

  • Large areas of Plains states now drier than during Dust Bowl

    As a result of the drought conditions that have largely remained a constant since 2011, parts of the Texas and Oklahoma panhandles, as well as northeastern New Mexico and southeaster Colorado, are now drier than they were during the infamous Dust Bowl of the 1930s. While experts explain that the possibility of another Dust Bowl is not likely due to modern farming and irrigation techniques which have been enacted as a response in the 1930s, greater erosion due to drought and wind has resulted in a number of vicious dust storms.

  • Bolstering shipping security

    During a press conference following the March 2014 Nuclear Secu­rity Summit in the Hague, President Barack Obama noted that his biggest security concern was not Russia — or any other regional superpower — but rather “the prospect of a nuclear weapon going off in Manhattan.” Experts say that the most likely way in which a nuclear weapon would potentially come to a major U.S. city is not on the tip of a missile but in the belly of a ship, noting that this view has been openly validated by the intelligence community. In 2007, Congress passed a law requiring all overseas cargo containers to be inspected before they are loaded on a U.S.-bound ship. That law, however, has never been enforced.

  • Battelle shows smart technology for biodefense and hazard avoidance

    Battelle last week announced production of the next generation chemical and biological hazard sensor system, which the company says operates at a fraction of the cost of current technologies. The technology, known as the Resource Effective BioIdentification System (REBS), is a battery-powered system capable of autonomous use with operating costs of less than $1 per day per unit (the company notes that current system costs that can range from $500 - $3,000 per day) and assay costs of $0.04 per sample (compared to current systems at over $100 per sample).

  • TSA expands PreCheck screening program to international airlines

    The TSA is expanding its PreCheckscreening program to passengers on international airlines. Air Canada is the first international carrier to join the list of PreCheck carriers, which already includes several U.S. airlines.Some international airlines are reluctant to join the PreCheck carrier list because it entails upgrading their computer systems to print a PreCheck logo and embed PreCheck data in their boarding pass barcodes. With Air Canada joining the list, the TSA believes other foreign carriers with a large U.S. passenger base would benefit if they offered PreCheck status to their customers.

  • Industry, Democrats reject GOP-sponsored TRIA-extension draft

    House democrats and members of Property Casualty Insurers, a leading insurance trade group, have rejected a Republican-sponsored draft proposal which would alter some measures of the current Terrorism Risk Insurance Act (TRIA). The Property Casualty Insurers did not mince words, calling the GOP plan “unworkable for the marketplace.” The proposal would raise the amount of damage caused by a terrorist attack from the current $100 million to $500 million before government coverage is triggered (the higher threshold would apply to attacks which do not involve nuclear, biological, chemical, or radiological means).

  • Farmers try to cope with the challenges posed by extreme weather

    Across the country, farmers are reporting that they are at yet another critical juncture for agriculture. Citing more unpredictable and severe weather due to climate change, scientists are researching defensive measures and looking to previous agricultural challenges for inspiration. Some are looking to the way individual farmers and government agencies addressed the Dust Bowl hardships of America during the Great Depression as a source of inspiration.

  • States lack expertise, staff to deal with cyberthreats to utilities

    The vulnerability of national electric grids to cyberattacks has caught the attention of federal utility regulators and industry safety groups, but state commissions tasked with regulating local distribution utilities are slow to respond to emerging cybersecurity risks. The annual membership directory of state utility regulators lists hundreds of key staff members of state commissions throughout the country, but not a single staff position had “cybersecurity” in the title.

  • Attackers exploited Microsoft security hole before company’s announcement

    Before Microsoft alerted its customers of a security flaw in Windows XP over a week ago, a group of advanced hackers had already discovered and used the vulnerability against targeted financial, energy, and defense companies.

  • California bill banning use of antibiotics in livestock withdrawn

    The Centers for Disease Control and Preventionreports that 23,000 people die every year from infections that cannot be cured, often due to overuse of antibiotics which creates drug resistant bugs. Last Wednesday, California Assemblyman Kevin Mullin (D-San Mateo) withdrew proposed legislation which would ban the sale of meat and poultry fed on nontherapeutic antibiotics. He lacked sufficient support from fellow legislators.

  • FBI warns healthcare providers about cybersecurity

    The FBI has issued a private industry notification (PIN), warning healthcare providers that their cybersecurity networks are not sufficiently secure compared to the networks of the financial and retail sectors, making healthcare systems even more vulnerable to attacks by hackers seeking Americans’ personal medical records and health insurance data. Healthcare data are as valuable on the black market than credit card numbers because the data contain information that can be used to access bank accounts or obtain prescription for controlled substances.

  • Fairbanks, Alaska UAV test site conducts first flight test

    The Pan-Pacific Unmanned Aircraft Systems Test Range Complex at the University of Alaska Fairbanks was established last year to help the Federal Aviation Administration (FAA) develop regulations and certifications for unmanned aircraft operators and equipment. The goal is to integrate them into the National Airspace System. On Monday, an Aeryon Scout mini quadcopter was the first UAV to be tested at the range. The range is the second of six UAV test sites to receive an FAA’s Certificate of Authorization.

  • South Carolina withdraws MOX lawsuit against DOE, NNSA

    The state of South Carolina said Friday that it would not go ahead with its lawsuit against the Department of Energy and the National Nuclear Security Administration (NNSA) in support of the Savannah River Site’s Mixed Oxide (MOX) Fuel Fabrication Facility. The dismissal of the lawsuit follows an announcement last Tuesday by the DOE and NNSA that construction will continue on the MOX facility through the end of the fiscal year. The two agencies made it clear, though, that they still plan to mothball the plant.

  • Lawmakers want DOE to reduce run-away costs of S.C. plutonium processing plant

    Lawmakers have given the Obama administration two weeks to submit a plan for reducing the cost of constructing the mixed-oxide fuel conversion (MOX) facility which would convert bomb-grade plutonium into nuclear fuel. The MOX facility at the Savannah River Site, South Carolina was launched to help the United States meet its nuclear arms reduction agreement with Russia, and agreement which called for the two countries to dispose of at least thirty-four metric tons each of weapons-grade plutonium.
