• More crude oil shipments by rail mean more accidents, but security measures lag

    American rail companies have long operated under federal laws, making it difficult for local officials to gather information on cargo and how rail companies select their routes. An increase in the number of trains transporting crude oil, accompanied by a series of derailments and explosions, has highlighted the dangers of transporting hazardous substances by rail.In February, the Department of Transportation announced that railroads had voluntarily agreed to apply the same routing rules to oil trains that they currently apply to other hazardous materials. Critics say more needs to be done.

  • Oklahoma worries that fracking-induced earthquakes threaten the state’s bridges

    Many residents in Oklahoma are questioning whether hydraulic fracking is to blame for the sudden increase in earthquakes, but for transportation officials, the security of the state’s 6,800 bridges is the immediate concern. There are 468 bridges in Oklahoma which are classified as “structurally deficient,” and most were not built with frequent earthquakes in mind. Earthquakes have become so common, however, that inspectors have had to inspect bridges several times a week.

  • Florida moves to protect coastal roads from sea level rise

    Alton Road is a few blocks west of the Atlantic Ocean, and is Miami Beach’s lowest point, at 2.8 feet above sea level. Trouble is, as a result of sea level rise, inundation tide now routinely reaches 3.4 feet above sea level. Geologist have long warned of the impact sea level rise would have on Florida’s coastal infrastructure, and they view Alto Road as Ground Zero, saying that at some point in the near future, water from flooding will not recede. The Florida Department of Transportation (FDOT) is taking steps to protect coastal transportation infrastructure from sea level rise.

  • Demand for terrorism insurance remains strong

    The fourth editionof the Terrorism Risk Insurance Report has found that demand for terrorism insurance remains strong and the renewal of the Terrorism Risk Insurance Program Reauthorization Act (TRIA) plays a key role in making coverage available and affordable. A survey of roughly 2,600 organizations found that the demand and price for terrorism insurance has remained constant since 2009. Education organizations purchase property terrorism insurance at a higher rate, 81 percent, than companies in any other industry segment surveyed in 2013, followed by healthcare organizations, financial institutions, and media companies.

  • New York public transit systems preparing for sea-level rise

    The Metropolitan Transportation Authority (MTA), which operates many New York state public transit lines, is beginning measures to factor for future sea-level rises within its projected five-year capital plans.Tobey Ritz, chief engineer of capital engineering at Metro-North, said: “It’s not so much for us to pick which study [of sea-level rise] is right, but to look at the entire range [of sea-level rise predictions], look at the time frames that are predicted and then consider when is the right time to act.”

  • Intelligent urban planning to drive climate change solutions

    A leaked report from the Intergovernmental Panel on Climate Change (IPCC) suggests that intelligent urban planning and investment in public transportation, especially in developing countries, could be the key factors in lower greenhouse gas emissions and reversing the effects of climate change.

  • Promoting nuclear power to avoid geoengineering

    There are two basic geoengineering strategies to reduce climate change: injecting aerosols such as sulfates into the stratosphere to block a portion of the sun’s radiation and thereby cool the Earth, much as volcanic emissions do; and the large-scale removal of carbon dioxide from the atmosphere. The aerosol-injection approach is much more likely to be pursued at current stages of technological development. Scientists say that in order to avoid the need for geoengineering, which could have enormous unforeseen consequences, the international community should pursue increased deployment of nuclear power plants, which do not emit carbon dioxide, to address the climate crisis. Many climate scientists are generally supportive of nuclear engineering and less fearful of it than they are of geoengineering.

  • Odds of storm waters overflowing Manhattan seawall up 20-fold, new study says

    Maximum water levels in New York harbor during major storms have risen by nearly two and a half feet since the mid-1800s, making the chances of water overtopping the Manhattan seawall now at least twenty times greater than they were 170 years ago, according to a new study. Whereas sea-level rise, which is occurring globally, has raised water levels along New York harbor by nearly a foot and a half since the mid-nineteenth century, the research shows that the maximum height of the city’s “once-in-10-years” storm tide has grown additionally by almost a foot in that same period.

  • Room-scouting robot to help first responders, soldiers

    Firefighters, police officers, and military personnel are often required to enter rooms with little information about what dangers might lie behind the door. A group of engineering students at Arizona State University is working on a project which would help alleviate that uncertainty. The product they are building consists of a laser sensor attached to a motor that sweeps all the way around a room, taking 700-800 individual scans, each one with about 680 unique data points. This information is transmitted to a computer program that creates a picture of the room and all its contents. Whoever is controlling the sensor remotely can see and analyze the data in real-time, as it is being collected.

  • Emergency water treatment guidelines questioned

    During floods and other emergencies, treating water for drinking is a must, but how to do it is up for debate. The Environmental Protection Agency’s (EPA’s) recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens and are often impractical to carry out, a new study has found.

  • Boston bombing spurred small, midsize businesses to buy terrorism insurance

    After the 2013 Boston Marathon bombing, terrorism insurance, designed for large businesses, became a necessary business expense for many midsize and small firms. Some 160 companies near the Boston explosion submitted insurance claims for property damage or business losses and only 14 percent had coverage for terrorism. “The Marathon attack changed the calculus,” an insurance industry insider says. “It taught us terrorism is a risk to businesses of every scale and size.”

  • Dams will not reduce flow of sand to Mississippi River Delta

    The wetlands of the Mississippi River Delta are slowly sinking and rapidly eroding, but new research has found the river’s supply of sand — the material engineers most need to rebuild the delta — will stay constant for centuries. The new study is encouraging news for scientists and government officials who are working to shore up southeastern Louisiana’s rapidly disappearing wetlands.

  • Small Virginia town debates cost of emergency siren system

    Installing an emergency siren system in Danville, Virginia would be too expensive, Danville fire chief David Eagle said during a recent update to the Danville city council on emergency notification systems. The city’s last siren system was discontinued about twenty-five years ago. A new system would cost between $300,000 and $400,000 to install, and would incur annual maintenance cost.

  • Dynamic atolls give hope that Pacific Islands can defy sea rise

    It is widely predicted that low-lying coral reef islands will drown as a result of sea-level rise, leaving their populations as environmental refugees. New evidence, however, now suggests that these small islands will be more resilient to sea-level rise than we thought. The new findings suggest that, rather than being passive lumps of rock that will be swamped by rising seas and eroded by storms, the islands are dynamic structures that can move and even grow in response to changing seas. Although the islands may survive into the future, the changes could still affect issues like fresh water and agriculture, potentially making life on these islands much more difficult than it is today.

  • Congress urged to renew the Terrorism Risk Insurance Act

    The Terrorism Risk Insurance Act (TRIA) is set to expire at the end of 2014 and members of Congress are urging its reinstatement before it is too late. The bill was enacted in 2002 in response to 9/11, and requires private insurers to offer terrorism coverage to individuals, with government assistance should the total payout from an event exceeds $100 million.
