• Communities near chemical plants should develop preparedness, response plans: Experts

    Researchers found that despite the 2007 passage of the Chemical Facility Anti-Terrorism Standards (CFATS), only a few chemical facilities have completed the necessary security measures implementation. The authors recommend that communities should not wait for CFATS to be implemented before developing their own preparedness and response plans in anticipation of possible chemical disasters in the future, whether caused by terrorism or accident.

  • New guidance on estimating area affected by a chlorine release issued

    Arlington, Virginia-based Chlorine Institute (CI) has issued a new version of Pamphlet 74 - Guidance On Estimating the Area Affected By A Chlorine Release. The new version, Edition 6, dated June 2015, reflects CI’s collaboration with the U.S. Department of Homeland Security’s Chemical Security Analysis Center and incorporates information obtained from the DHS “Jack Rabbit I” chlorine release field tests.  

  • U.S. military bases vulnerable to cyberattacks on their power, utility systems

    U.S. military bases are at risk for cyberattacks against the bases’ power grid and other utility systems, according to a new report on defense infrastructure from the Government Accounting Office. The 72-page GAO document concludes military bases “may be vulnerable to cyber incidents that could degrade operations and negatively impact missions.”

  • Different lessons from past floods

    More and more frequent extreme weather events lead to new projects on risk management and spatial planning. Past experiences represent an added value and suggest the importance of greater involvement of local communities. Luckily, past mistakes can sometimes be useful for present or especially future decisions. This can apply to spatial planning and management in response to natural disasters and extreme weather events.

  • Israel bolsters cyber defenses to cope with an escalating number of cyberattacks

    In 2013, Israel’s grid was cyberattacked, on average, a few hundred times per hour. Last year the average hourly attacks on Israel’s grid was 20,000.The number of detected cyberattacks on Israel reached two million a day during the war with Hamas last summer. The Israeli government decided there was a need to reorganize and improve the cyberdefense systems protecting Israel’s critical infrastructure.

  • Strengthening urban infrastructure to withstand extreme weather-related events

    A multi-disciplinary team of about fifty researchers from fifteen universities and other institutions will address the vulnerability of urban infrastructure to extreme weather related events, and ways of reducing that vulnerability. Funded under a $12 million research grant from the National Science Foundation (NSF), the researchers will conduct their extensive work over the coming five years. In light of weather related extremes, such as increasing storm frequency and intensity, as well as climate uncertainties, this network will evaluate threats to transportation, electricity, water, and other services in major urban areas, and the social, ecological, and technical systems to protect infrastructure and increase its flexibility and adaptability, using new designs and technologies.

  • Washington, D.C. sinking fast, compounding threat of sea-level rise

    New research confirms that the land under the Chesapeake Bay is sinking rapidly and projects that Washington, D.C., could drop by six or more inches by the end of this century — adding to the problems of sea-level rise. This falling land will exacerbate the flooding that the nation’s capital faces from rising ocean waters due to a warming climate and melting ice sheets — accelerating the threat to the region’s monuments, roads, wildlife refuges, and military installations. “It’s ironic that the nation’s capital — the place least responsive to the dangers of climate change — is sitting in one of the worst spots it could be in terms of this land subsidence,” says one researcher. “Will the Congress just sit there with their feet getting ever wetter?”

  • Israel shares its approach, solutions to drought with California

    Israel has developed expertise in coping with droughts, and a delegation from Israeli water companies recently visited California, meeting with state officials and corporations to propose solutions to the drought, now in its fourth year. It was the latest in a series of consultations and symposiums highlighting Israeli water expertise and its potential to help California.

  • Safer structures to withstand earthquakes, windstorms

    A new cyberinfrastructure effort funded by a $13.7 million grant from the National Science Foundation will help engineers build safer structures that can better withstand natural hazards such as earthquakes and windstorms. Researchers aim to build a software platform, data repository, and tools that will help the United States design more resilient buildings, levees, and other public infrastructure that could protect lives, property and communities.

  • Sea level rise, storm surges increasing risk of “compound flooding” for major U.S. cities

    Scientists investigating the increasing risk of “compound flooding” for major U.S. cities have found that flooding risk is greatest for cities along the Atlantic and Gulf coasts when strong storm surge and high rainfall amounts occur together. While rising sea levels are the main driver for increasing flood risk, storm surges caused by weather patterns that favor high precipitation exacerbates flood potential.

  • Mangroves help protect coasts against sea level rise

    Mangrove forests could play a crucial role in protecting coastal areas from sea level rise caused by climate change, according to new research. Taking New Zealand mangrove data as the basis of a new modelling system, the researchers were able to predict what will happen to different types of estuaries and river deltas when sea levels rise. They found areas without mangroves are likely to widen from erosion and more water will encroach inwards, whereas mangrove regions prevent this effect - which is likely due to soil building up around their mesh-like roots and acting to reduce energy from waves and tidal currents.

  • Where does solar energy stand, where does it need to go to fulfill its potential?

    Most experts agree that to have a shot at curbing the worst impacts of climate change, we need to extricate our society from fossil fuels and ramp up our use of renewable energy. The sun’s energy is unlimited, free and clean, and the amount that hits Earth in one hour is equal to the amount of energy used in one year by the entire planet. Yet, although installed global photovoltaic capacity increased almost nine-fold and the price of solar panels dropped by two-thirds between 2008 and 2013, only 1 percent of U.S. and global electricity generation come from solar energy. Where does solar energy stand today, and where does it need to go in order for us to make the transition to renewable energy?

  • Fusion Centers important in promoting cybersecurity

    Fusion centers were created after 9/11 to serve as primary focal points for state, local, federal, tribal, and territorial partners to receive, analyze, and share threat-related information. States can promote cybersecurity and enhance their capabilities by heightening the importance of cybersecurity as a mission of fusion centers, according to a paper released the other day by the National Governors Association (NGA).

  • Is your fear of radiation irrational?

    Radioactivity stirs primal fears in many people, but that an undue sense of its risks can cause real harm. Invisible threats are always the most unnerving, and radiation is not something you can see. Nor can you control it. The traditional secrecy of the biggest commercial user of radiation, the nuclear power industry, hasn’t helped. A justified fear of high and uncontrolled levels of radiation has thus undermined our willingness to see that the risks it poses at low levels are either acceptable or manageable.

  • Integrating renewable and nuclear power plants into the electrical grid

    “Electrical grids can work if, and only if, the amount of electricity inserted into the grid from power plants is matched, second by second, to the amount of electricity extracted from the grid by consumers.” If this does not happen there are black-outs. In order to maintain this equilibrium we must focus on two things: demand and supply of electricity into the grid. New research into sustainable energy systems focuses on integrating renewable and nuclear power plants into the electrical grid — a topic high on the agenda for scholars, industry, and policy makers.
