• Using hills to shelter buildings from tornadoes

    Researchers have demonstrated the influence of hills on tornadoes. The researchers’ models revealed that the height of a hill and the size of a tornado’s vortex have a significant effect on the tornado’s destructive power. The findings could be used to identify safer areas for construction.

  • U.S. formulates strategy for a new Arctic landscape

    U.S. national security officials have become increasingly concerned about the national security implications of an ice-free Arctic. The Arctic will become ice-free during the summer by mid-decade. In a strategy document, the Pentagon says: “Melting sea ice in the Arctic may lead to new opportunities for shipping, tourism, and resource exploration, but the increase in human activity may require a significant increase in operational capabilities in the region in order to safeguard lawful trade and travel and to prevent exploitation of new routes for smuggling and trafficking.”

     

  • Canadian city developed mathematical formula to evaluate risk

    The City of Hamilton, Ontario has ranked Terrorism fourth on its list of top ten emergency risks, below Hazardous Materials and Explosions, Energy Supply Emergencies, and Epidemics/Pandemics.The city’s ranking of top 10 emergencies for which it plans is not a mere judgment call: The city’s emergency management office uses a mathematical equation to rate the risks to the city and its population.

  • Maryland preparing for sea level rise

    Maryland has 3,100 miles of tidal shoreline. A scientific report recommends that it would prudent for the state to prepare for a sea level rise of 1.4 feet by 2050.Maryland’s CoastSmart Communities Initiative (CCI) provides grant funding for coastal communities which want to reduce their vulnerabilities to the effects of coastal hazards and sea level rise by becoming ready, adaptive, and resilient.

  • Budget impasse halts enforcement of chemical plants safety standards

    Security experts say that short of a direct nuclear attack on a U.S. city, the most dangerous, mass-casualty catastrophe the United States faces is a terrorist attack on, or an accident in, a chemical facility which would release toxic clouds over neighboring cities and towns. The federal government partial shutdown is making it impossible to enforce safety and security standards formulated to strengthen the ability of thousands of U.S. chemical facilities to withstand terrorist attacks.

  • Halt of CFATS work disrupts debate over program’s merit

    The budget impasse-related halting of monitoring and enforcing compliance with the 2007 Chemical Facility Anti-Terrorism Standards (CFATS) comes at a time of growing criticism of the measure by GOP – but not only GOP – lawmakers, who complain that there are too many problems with CFATS and the way it has so far been implemented.

  • Furloughs hamper U.S. ability to respond to chemical disasters

    Rafael Moure-Eraso, the chairman of the U.S. Chemical Safety Board(CSB) warned that the agency would be unable to respond to major chemical-related disasters if the government shutdown continued. The agency has furloughed more than 90 percent of its workers. The shutdown has delayed other CSB investigations into chemical accidents in California, Utah, Washington, and Texas. Moure-Eraso said that the delays in investigations could threaten public safety as the agency is unable to make recommendations for prevention of similar accidents.

  • Long-term trend of saltwater intrusion in the Everglades confirmed

    Mangroves love salt water, while sawgrass depends on fresh water. Satellite imagery over the southeastern Everglades confirms long-term trends of mangrove expansion and sawgrass habitat loss near the shore. The trend is related to salt water intrusion caused by sea-level rise and water management practices. Changes in water management, such as the implementation of the Comprehensive Everglades Restoration Plan, may help offset the possible effects caused by future salt water intrusion, but restoration may not suffice if sea-level rise accelerates.

  • Rural California country faces levee dilemma

    About 400 homes and rich farmland in District-10 of Marysville, California risk being flooded should the levees protecting the area fail. The levees, stretching over twenty-eight miles, were built in the early 1900s. The area’s low population may be one reason why county officials have neglected making improvements to the levees in District-10. Local opponents of investment in shoring up the levees are worried that if the levees are improved and the area made safer, “It would open the door for more agribusiness type things, but it would also open the door for more subdivisions,” in the words of one of them.

  • N.J. coastal wetlands moderated some of Hurricane Sandy’s fury

    Monitoring sensors along the New Jersey coast recorded marsh and wetland swelling during Hurricane Sandy. That swelling is an indication of marshes’ ability to absorb some of the storm surge — which, in hard-hit urban areas, had resulted in high water marks up to seven feet during Hurricane Sandy. Resilient, healthy wetlands near coastal areas have a key role in protecting local communities from hurricane-induced storm surges and flooding.

  • Policies governing rural land use can curb wildfire risks – up to a point

    Using Montana’s fast-growing Flathead County as a template, researchers hves found that moderately restrictive land-use policies can significantly curb the potential damage of rural wildfires. Highly restrictive planning laws, however, will not do much more.

  • First ever evidence discovered of a comet striking Earth

    The first ever evidence of a comet entering Earth’s atmosphere and exploding, raining down a shock wave of fire which obliterated every life form in its path, has been discovered. The comet entered Earth’s atmosphere above Egypt about twenty-eight million years ago. As it entered the atmosphere, it exploded, heating up the sand beneath it to a temperature of about 2,000 degrees Celsius, and resulting in the formation of a huge amount of yellow silica glass which lies scattered over a 6,000 square kilometer area in the Sahara.

  • U.S. nation-wide quake early-warning system

    The United States is likely to be struck by a major earthquake within the next twenty years. Scientists say that instead of waiting to experience a devastating earthquake and then invest in preventative measures for subsequent earthquakes, the country should be proactive and take action before the event. Investing in a nationwide earthquake warning system will save lives, prevent destruction of key infrastructure, and reduce the size of the economic loss that may result from an earthquake.

  • Bolstering water security in a crowded world

    With limited water and the increasing number of people depending on it – there will be more than nine billion people on the planet by 2050 — water security is tenuous. Integrated water management plans using “blue,” “green,” and “gray” water, however, can increase water security by allowing agriculture to rise to the challenge of feeding a growing world population while leaving enough water for other uses.
