• All-natural mixture offers promising fire retardant

    What sounds like fixings for a wizard’s potion — a dash of clay, a dab of fiber from crab shells, and a dollop of DNA— actually are the ingredients of promising green fire retardants invented by NIST researchers. Applied to polyurethane foam, the bio-based coatings greatly reduced the flammability of the common furniture padding after it was exposed to an open flame. Peak and average rates of heat release — two key indicators of the magnitude of a fire hazard — were reduced by 48 percent and 77 percent.

  • Nationwide effort launched to weather-harden Canadian cities

    The frequency and magnitude of extreme weather events in Canada — from the floods in Southern Alberta and Toronto to the December ice storm in Central and Eastern Canada — are increasing, causing billions of dollars in damage to infrastructure, businesses and homeowners. Intact Financial Corporation and the University of Waterloo announced a national initiative involving the implementation of twenty climate change adaptation projects designed to reduce the physical, financial, and social impacts of extreme weather events in Canada.

  • Santa Monica to require retrofit of earthquake-vulnerable buildings

    Last week, the Santa Monica City Councilauthorized city officials to hire engineering consultants to help identify buildings built before 1996 which could potentially be at risk in a major earthquake.. Owners of vulnerable buildings would be notified and provided recommendations on how to best retrofit their buildings to make them more resilient. Santa Monica will become the first city in California to require retrofitting for concrete, steel, and wood-frame. San Francisco last year required similar retrofitting, but only for wood apartment buildings.

  • Hurricanes with female names deadlier than male-named storms

    In the coming Atlantic hurricane season, watch out for hurricanes with benign-sounding names like Dolly, Fay, or Hanna. According to a new study, hurricanes with feminine names are likely to cause significantly more deaths than hurricanes with masculine names, apparently because storms with feminine names are perceived as less threatening.

  • U.K. to face heavier, more frequent summer downpours, more destructive flash floods

    Global warming could cause extreme summer downpours to become several times more frequent in the United Kingdom by 2100, a new study suggests. Its authors say this will likely lead to an increased risk of flash flooding, similar to the Boscastle floods of 2004 and the “Toon Flood” in Newcastle in 2012.

  • The five biggest threats to human existence

    In the daily hubbub of current “crises” facing humanity, we forget about the many generations we hope are yet to come. Not those who will live 200 years from now, but 1,000 or 10,000 years from now. The word “hope” is appropriate because we face risks, called existential risks, which threaten to wipe out humanity. These risks are not just for big disasters, but for the disasters that could end history. These risks remain understudied. There is a sense of powerlessness and fatalism about them. People have been talking apocalypses for millennia, but few have tried to prevent them. Humans are also bad at doing anything about problems that have not occurred yet because of the tendency to overestimate the probability of events we know examples of, and underestimate events we cannot readily recall. There are some risks we cannot do anything at all about, such as gamma ray bursts that result from the explosions of galaxies. But if we learn we can do something, the priorities change.

  • The Pentagon integrates climate change into military planning

    With the release of the National Climate Assessment last month, a clearer picture has emerged of the official policy-related interpretation of climate change data. The debate may still go on amongst civilian branches of government, and between the administration and its critics, the Pentagon, for some time now, has already been integrating climate change-related policies into its daily operations across all branches of the military.

  • Sea level rise, not Hurricane Sandy impacts, main cause of subsequent East Coast storm flooding

    Flooding in coastal areas bordering Great South Bay, New York, and Barnegat Bay, New Jersey caused by winter storms that occurred following Hurricane Sandy was not influenced by changes Sandy made to barrier islands or other bay features, according to a new U.S. Geological Survey study. “While the existing barrier island and inlet system shield the mainland to a great extent from the daily tides, most of the storm surge, and all long-term changes in water level, such as those resulting from sea level rise, reach the mainland,” say the study’s authors.

  • Extreme weather events threaten U.S. national landmarks

    Rising seas, floods, and wildfires are threatening the U.S. most cherished historic sites — from Ellis Island to the Everglades, Cape Canaveral to California’s César Chávez National Monument. Scientists say that today these sites face an uncertain future in a world of rising sea levels, more frequent wildfires, increased flooding, and other damaging effects of climate change. At some sites — such as Liberty and Ellis Islands and Cape Hatteras — steps have already been taken to prepare for these growing climate risks. At many other sites, such efforts have not yet begun.

  • Extreme weather exposes the toxic legacy of an industrial past

    The increase in the number and intensity of extreme weather events in the United States carries with it yet another, more insidious danger: it forces to the surface toxic lead from long-shuttered smelters. Lead smelters had mostly closed down in the United States by the 1980s, but they left behind millions of tons of toxic waste. One example: In 2011, Joplin, Missouri suffered a devastating tornado which killed 158 people and flattened much of the city. Decades of lead processing in the Joplin area had created about 150 million tons of toxic wastes, with about 9 million tons still remaining after a federal Superfund cleanup. The 2011 tornado forced some of the buried lead to the surface, forcing Joplin to spend $3.5 million so far on lead clean up. The city now requires builders to test for lead, and clean up any traces, before beginning construction.

  • Rio builds a high tech integrated urban command center

    Rio de Janeiro is one of the most densely populated cities in South America. Much of the city is vulnerable to flooding, and about three-quarters of Rio’s districts have areas at risk of landslides. High temperatures can make living situations unbearable. In addition, a high crime rate and poor infrastructure make the city difficult to govern. In preparation for the 2014 World Cup and 2016 Summer Olympics, authorities are looking to improve response times to disasters and establish a more efficient system to deal with the city’s many challenges. One of the solutions is a high tech integrated urban command center — Centro de Operações Preifetura do Rio de Janeiro (COR) – which unites Rio’s thirty departments and some private suppliers in a single monitoring room where operators can track real-time conditions of the city and coordinate a response to emergencies and disruptions.

  • Canada is not doing enough to prepare for, cope with natural, man-made disasters

    The 2013 Alberta floods cost more than $6 billion, making it the worst weather disaster in Canada’s history. Before 1990, only three Canadian disasters exceeded $500 million, but in the past ten years alone nine disasters have exceeded that amount. Disaster management experts said that while it may be understandable that corporate and municipal budgets for disaster training and preparations have been reduced during the economic slowdown, corporate and government leaders in Canada must consider how such reductions would impact the ability of communities to build adequately resilience systems against potential natural and manmade disasters.

  • Rising sea levels will be too much, too fast for Florida

    The U.S. National Oceanic and Atmospheric Administration (NOAA) published its assessment of sea level rise in 2012 as part of the National Climate Assessment. Including estimates based on limited and maximum melt of the Greenland and Antarctic ice sheets, it anticipated a raise of 4.1 to 6.6ft (1.25 to 2m) by 2100, reaching 2ft (0.6m) by around 2050 and 3ft (0.9m) by around 2075. This means that by the middle of this century most of the barrier islands of south Florida and the world will be abandoned and the people relocated, while low areas such as Sweetwater and Hialeah bordering the Everglades will be frequently flooded and increasingly difficult places to live. Florida will start to lose its freshwater resources, its infrastructure will begin to fail, and the risk of catastrophic storm surges and hurricane flooding will increase. Florida counties should be planning for their future to determine at what point the costs of maintaining functional infrastructure, insurance, and human health and safety becomes economically impossible. Already, there are areas and properties that will become unlivable within a 30-year mortgage cycle.

  • NOAA predicts near-normal or below-normal 2014 Atlantic hurricane season

    In its 2014 Atlantic hurricane season outlook issued yesterday NOAA’s Climate Prediction Center is forecasting a near-normal or below-normal season. The main driver of this year’s outlook is the anticipated development of El Niño this summer. El Niño causes stronger wind shear, which reduces the number and intensity of tropical storms and hurricanes. El Niño can also strengthen the trade winds and increase the atmospheric stability across the tropical Atlantic, making it more difficult for cloud systems coming off of Africa to intensify into tropical storms.

  • Public-private partnership proposed to fund Calif. seismic early warning system

    California state agencies federal agencies, are proposing a partnership between public and private agencies to build the $23.1 million earthquake early warning system in the state, and fund the $11.4 million annual operating budget. Governor Jerry Brown signed Senate Bill 135 in 2013 authorizing construction of the warning system, but the bill does not provide or allocate funding, despite a plan to have the system active in two years. The early warning system will provide Los Angeles residents up to a minute’s notice if a large earthquake is generated on the San Andreas Fault in the Salton Sea area. The system could also provide warnings for earthquakes that occur throughout California’s earthquake-prone landscape.
