• New report identifies populations most vulnerable to extreme weather events

    Extreme weather events leave populations with not enough food both in the short- and the long-term. A new report has looked at which sections of the population are left most exposed to food shortages after extreme weather events, and concluded that better governance could have lessened the impact on the poorest and most vulnerable, and that affected populations have been let down by the authorities in the past.

  • NSF awards $15 million in second round of coastal sustainability grants

    More than half the world’s human population lived in coastal areas in the year 2000; that number is expected to rise to 75 percent by 2025. If current population trends continue, projections are for the crowded U.S. coast to see its population grow from 123 million people to nearly 134 million people by 2020. In wake of storms such as Hurricanes Sandy and Isaac, the NSF awards focus on better management of coastal environments.

  • To stay below 2°C warming, coal’s rapid phase out is essential, but not enough

    A rapid phase out of coal as an electricity source by 2050 would reduce warming by half a degree, according to a new study. The study authors ran a number of scenarios around phasing out fossil fuel emissions from the electricity sector, which produces around 40 percent of global C02 emissions. The electricity sector needs to be decarbonized faster than other sectors, but instead is heading in the opposite direction, increasing carbon intensity and significantly driven by increased coal use, and making it one of the largest sources of recent carbon emission increases.

  • Ten years after Hurricane Ivan, Alabama communities are better prepared

    Since Hurricane Ivan struck Baldwin County, Alabama and neighboring communities ten years ago, building officials have adopted better resilience protocols to protect human life and property from future storms. Ivan, which left an estimated $14.2 billion in damages throughout the Gulf Coast, is considered the worst storm to hit Alabama in twenty-five years, and the seventh most costly hurricane ever to affect the United States.

  • SF posting seismic warning posters on vulnerable buildings in a retrofitting drive

    In an effort to get property owners to retrofit vulnerable buildings, San Francisco is posting large signs — in English, Spanish, and Chinese, with red letters, and a drawing of a collapsed building — on apartment and hotel complexes that have failed to comply with the city’s seismic safety laws.The San Francisco tactic is similar to what city officials in Berkeley implemented in 2005, when building authorities placed small warning signs on at-risk wooden apartment buildings.

  • Simulating the ground motion of the south Napa earthquake

    Lawrence Livermore National Laboratory (LLNL) seismologists are tapping into LLNL’s supercomputers to simulate the detailed ground motion of last month’s magnitude 6.0 south Napa earthquake. The Napa tremor is the largest to hit the Bay Area since the magnitude 6.9 Loma Prieta event in 1989. Seismic simulations allow scientists better to understand the distribution of shaking and damage that can accompany earthquakes, including possible future “scenario” earthquakes.

  • A Santa Ana Wildfire Threat Index developed

    UCLA atmospheric scientists were instrumental in the creation of the Santa Ana Wildfire Threat Index — a new tool to classify the fire threat potential of the powerful, hot, dry Santa Ana wind, which can turn a spark into an inferno. The index was introduced 17 September by the U.S. Forest Service, in collaboration with UCLA and San Diego Gas and Electric.

  • Silicon Valley tech startups developing earthquake early warning mobile apps

    Silicon Valley tech startups are developing mobile applications to alert residents about earthquakes, but most lack a direct source to the seismic sensors deployed by the state’s ShakeAlertsystem which sends alerts seconds before the ground begins to shake.Googleis currently the only tech company with an agreement to access ShakeAlert’s data feed, and analysts anticipate that Google will integrate ShakeAlert’s system with its Nestthermostat, a Web-connected thermostat that sends alerts to users’ phone and e-mail with details on home temperature and energy use.

  • Tornadoes occurring earlier in Tornado Alley

    About 1,300 tornadoes hit the United States every year, killing an average of sixty people. Peak tornado activity in the central and southern Great Plains of the United States is occurring up to two weeks earlier than it did half a century ago, according to a new study whose findings could help states in “Tornado Alley” better prepare for these violent storms.

  • Cities seek new ways to cope with sea level rise – and look to the Dutch for advice

    Scientists predict a “tenfold increase” in the frequency of hurricanes and other storms, as well as sea-level rise of eleven to twenty-four inches within a little more than three decades – and planners and managers in U.S. coastal cities are looking at new ways to prepare their cities’ infrastructure for these challenges. In New York and New Orleans, city planners are studying the experience of the Dutch, who have gained a lot of experience – and fame — for their water control methods.

  • The State of New York launches disaster preparedness initiatives

    The state of New York is implementing a proactive strategy to deal with the threat of terrorism and natural disasters like Superstorm Sandy. Local municipalities have been granted state support for emergency preparedness projects, and the state’s Division of Homeland Security and Emergency Services(DHSES), led by commissioner Jerome Hauer, has expanded its regional footprint from five planning/response regions to ten. “Mother Nature has become much more aggressive, so we too must adopt a similar posture to ensure we are ready to respond effectively when the next disaster strikes, Hauer says.

  • Rural towns lose to urban centers in competition for coastal protection funding

    Infrastructure protection planners say there are only three ways coastal communities can defend themselves against rising sea levels: defend the shoreline with both natural and man-made barriers; raise key infrastructure such as buildings and roads; or retreat from the shoreline. Each of these options costs a fortune to follow. Smaller, more rural coastal communities in many states are finding that they are having a hard time competing with more powerful interests in coastal urban cities over funding for protection against sea-level rise.

  • Not all Oakland buildings are equally seismically vulnerable

    A mobile app which allows Oakland resident to check on whether their buildings are seismically vulnerable reveals that there is a vast inequality between safe and vulnerable homes in the city, as residents living in less-affluent, older multi-unit buildings would suffer the most in a major quake. Oakland is home to hundreds of those vulnerable buildings that may collapse in a major earthquake, and there is no law mandating property owners to retrofit buildings to safer standards.

  • Colorado recovering as it marks one year anniversary of devastating flood

    On 29 September 2013 Colorado experienced the most severe natural disaster that had ever befallen the state. Within three days much of the state had experienced a rainfall equivalent to its total for the entire year. In the end, nine people died, nearly 1,000 were evacuated by helicopter, and 1,800 homes were destroyed. The total cost of the damage reached $2.9 billion. Now, a year later, Colorado is finally coming back.

  • Sea level rise affecting the infrastructure, psychology of key mid-Atlantic towns

    Scientific research and flooding trends have led many to speculate that the Atlantic coast of the United States is already sinking. Mid-Atlantic towns on the coast stretching from Virginia to South Carolina have been experiencing increased flooding and receiving reports and satellite findings from government agencies, leading many of those living on the mid-Atlantic coast to wonder whether their hometowns are doomed.
