• Increase in wildfires may significantly degrade air quality, health in the future

    As the American West, parched by prolonged drought, braces for a season of potentially record-breaking wildfires, new research suggests these events not only pose an immediate threat to people’s safety and their homes, but also could take a toll on human health, agriculture, and ecosystems.

  • The world likely to face more frequent, and more severe, blackouts

    U.S. household electricity usage increased by 1,300 percent between 1940 and 2001. In the last few decades, air conditioning has been the greatest factor in increased electrical consumption, and one of the greatest sources of systematic strain, with considerably more blackouts occurring in the summer months than during winter. The electricity used to fuel America’s air conditioning is currently of a similar volume to the U.S. entire energy consumption in the 1950s. A new study reveals that today’s occasional blackouts are dress rehearsals for the future, when they will occur with greater frequency and increased severity. Power cuts will become more regular around the globe as electrical supply becomes increasingly vulnerable and demand for technology continues to grow at an unprecedented rate.

  • Natural flood management as a solution against future flooding

    Natural Flood Management (NFM) aims to reduce the downstream maximum water height of a flood — the peak — or delay the arrival of the flood peak downstream, increasing the time available to prepare. Back-to-nature flood schemes which use the land’s natural defenses to slow river flow and reduce flooding could be a cost-effective way of tackling one of the biggest problems facing the United Kingdom today.

  • Israel considering earthquake-proofing important Biblical-period structures

    Israel is located in one of the world’s earthquake-prone areas, along the friction point of the African and Arabian tectonic plates.Officials in Israel are taking preventative measures to protect the country’s most important ancient sites from earthquake damage. Engineers from the University of Padua in Italy have installed sensors throughout the Tower of David, one of Jerusalem most important historical sites, to determine what sort of earthquake-proofing may be needed. Some experts opined that in the event of an earthquake, Jerusalem’s most ancient structures might actually be the city’s most dependable. “If they still stand after so many earthquakes during the last 2,000 years, they must be good structures,” one of them said.

  • Thumbnail-sized quantum cascade laser, tuning forks detect greenhouse gases

    Human activities such as agriculture, fossil fuel combustion, wastewater management, and industrial processes are increasing the amount of nitrous oxide in the atmosphere. The warming impact of methane and nitrous oxide is more than 20 and 300 times, respectively, greater compared to the most prevalent greenhouse gas, carbon dioxide, over a 100-year period. Methane and nitrous oxide detection is crucial to environmental considerations. Scientists use a thumbnail-sized quantum cascade laser (QCL) as well as tuning forks that cost no more than a dime to detect very small amounts of nitrous oxide and methane.

  • U.S. power plant emissions down

    Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis. The so-called “combined cycle” natural gas power plants also release significantly less nitrogen oxides and sulfur dioxide, which can worsen air quality.

  • Nearby Georgia basin may amplify ground shaking from quakes in Vancouver

    In Greater Vancouver, there are more than 700 12-story and taller commercial and residential buildings, and large structures — high-rise buildings, bridges, and pipelines — which are more affected by long period seismic waves, or long wavelength shaking. Researchers find that tall buildings, bridges, and other long-period structures in Greater Vancouver may experience greater shaking from large (M 6.8 +) earthquakes than previously thought due to the amplification of surface waves passing through the Georgia basin.

  • Coastal flooding in Ireland offers warning of things to come

    Flooding in Ireland and the U.K. is typically associated with heavy rainfall, but the reason for more recent coastal flooding is different. Experts say that the increases in mean sea level suggests that mean sea-level rise rather than storminess is largely contributing to the dramatic increase in the frequency and scope of coastal flooding. Major cities like Cork, Dublin, and Galway will soon feel the impact of sea-level rise, and developers are discouraged from building within 100 meters of soft shoreline.

  • Growing threat of intense tropical cyclones hitting East Asia

    The intensity of tropical cyclones hitting East Asia has significantly increased over the past thirty years, according to a new study. The coastlines of China, Korea, and Japan in particular have experienced increasingly stronger cyclones, which the researchers have attributed to increasing sea surface temperatures and a change in atmospheric circulation patterns over the coastal seas.

  • New L.A. fault map threatens Hollywood development projects

    The state of California recently released new geological maps which reveal the presence of an active earthquake fault along the path of major developments in Hollywood. The maps established a zone of 500 feet on both sides of the fault, and state law will require new developments within the zone to conduct underground seismic testing to determine whether the fault runs beneath planned development sites. Building on top of faults is prohibited. Three prominent Hollywood developments — the Millennium Hollywood skyscraper project, the Blvd6200 development, and an apartment project on Yucca Street — are within the 500-foot fault zone.

  • Healthcare industry to conduct cyberattack drill in March

    The American health care industry, in partnership with the federal government, will in March conduct simulated cyberattacks targeting industry networks and resources in an effort to test the industry’s vulnerability to cyberattacks. This will be the first time insurers, hospitals, pharmaceutical manufacturers, and HHS will run coordinated drills. Healthcare is one of seventeen critical infrastructure sectors which, if attacked, could have damaging consequences for the country.

  • Massachusetts takes steps to withstand climate change impacts

    Governor Deval Patrick of Massachusetts earlier this week unveiled a $50 million plan to help prepare Massachusetts for the challenges climate change poses to energy supplies, public health, transportation, and basic infrastructure in his state. A $40 million grant from the state’s Department of Energy Resources will help cities and towns develop protections around energy services, and $10 million will go toward shoring up critical coastal infrastructure and dam repair.

  • Aging natural gas pipelines leak under Washington, D.C. streets

    More than 5,893 leaks from aging natural gas pipelines have been found under the streets of Washington, D.C., a team of researchers finds. A dozen of the leaks could have posed explosion risks, the researchers said. Some manholes had methane concentrations as high as 500,000 parts per million of natural gas — about ten times greater than the threshold at which explosions can occur.

  • NRC: storing spent nuclear fuel in cooling pools is safe

    The nuclear reactors now in service in the United States were built with the assumption that the spent fuel would be removed from nuclear the facilities after a few years, but because the government has failed to provide a centralized place to store the spent fuel, utility companies have had to store an ever-growing quantity of it in spent fuel pools on the grounds of the facilities. Scientists argue that it would be safer to move some of the spent fuel into giant steel and concrete casks, where it can be stored dry, with no reliance on water, pumps, or filters to keep them cool. The nuclear industry and the NRC do not agree.

  • The causes of recent Caribbean earthquakes

    A 6.4-magnitude earthquake shook Puerto Rico Monday 13 January. It caused some power outages and cracked floors, but no major damage or injuries were reported. The quake, which struck the northern coastal town of Hatillo, is one of the largest to hit the U.S. territory in recent years. This event comes four days after a 5.0-magnitude earthquake rattled Havana, Cuba. Researchers say that the earthquake in Puerto Rico occurred on the North American-Caribbean plate boundary, whereas the earthquake in Cuba happened well inside the North American plate. Although inter-plate earthquakes do occur, often on older faults that are reactivated, they are less common than those that form at plate boundaries.
