• Prolonged heatwaves in urban areas increase significantly over past 40 years

    The world’s urban areas have experienced significant increases in heatwaves over the past forty years, according to new research published last week. These prolonged periods of extreme hot days have significantly increased in over 200 urban areas across the globe between 1973 and 2012, and have been most prominent in the most recent years on record. The study is one of the first to focus solely on the extent of extreme weather on a global scale, as well as examining disparities between urban and non-urban areas.

  • Corps of Engineers’ report details North Atlantic region’s coastal storm, flood risks

    The U.S. Army Corps of Engineers last week released to the public a report detailing the results of a two-year study to address coastal storm and flood risk to vulnerable populations, property, ecosystems, and infrastructure in the North Atlantic region of the United States affected by Hurricane Sandy in October, 2012. The NACCS provides tools and information, including a nine-step Coastal Storm Risk Management Framework that can be used by communities, states, tribes, and the Federal government to help identify coastal risk and develop strategies for reducing those risks.

  • Projects using federal funds to adopt siting, building codes informed by sea-level rise

    Following remarks about climate change in his recent State of the Union speech, President Barack Obama issued an executive orderlast week directing federal, state, and local government agencies, using federal funds, to adopt stricter building and siting standards to reflect scientific projections that future flooding will be more intense and frequent due to climate change. Already, post-Superstorm Sandy, FEMA and (HUD) developed updated elevation standards for New York, New Jersey, Connecticut, Maryland, and Rhode Island based on climate change projections, and required any approved projects to reflect those projections or local elevation requirements if they were tougher.

  • Severe-weather warnings most effective if probability included: Study

    Risk researchers find that the public may respond best to severe weather warnings if they include a probability estimate, an important finding not only for the present but also for the longer-term future as climate change brings more frequent and severe threats. As severe storm and other disaster warnings become more frequent, new research in this field could become critical for reducing weather-related injury and death.

  • Global warming won't lead to more storms, but will make storms stronger

    A study by atmospheric physicists finds that global warming will not lead to an overall increasingly stormy atmosphere, a topic debated by scientists for decades. Instead, strong storms will become stronger while weak storms become weaker, and the cumulative result of the number of storms will remain unchanged.

  • Preparing the Pacific Northwest for the Big One

    More than three hundred years ago this week, the geologic fault off Washington and Oregon’s coast lurched and caused a massive earthquake. The resulting tsunami sent ocean water surging far inland, and generated waves felt across the Pacific Ocean in Japan. Now, on the quake’s 315th anniversary, scientists are helping prepare the region for a repeat event that could come at any time. Efforts include helping design the first tsunami evacuation structure in the United States, a campus-wide research project on major earthquakes, and an upcoming rollout of early earthquake alerts.

  • N.C. considering regulations to cope with sea-level rise

    Later this week, researchers peer-reviewing the latest draft report that investigates sea-level rise along North Carolina’s coast, will submit their comments to the state Coastal Resources Commission’s(CRC) Science Panel. The initial 2010 report faced criticism from climate change skeptics and some property developers who claimed the report’s 100-year outlook on sea-level rise was unrealistic. The new report looks at changes along the coast for a period of thirty years.

  • Priorities for ocean science over next decade: Sea-level rise, geohazards

    A new report from the National Research Council identifies priority areas for ocean science research in the next decade, including the rate and impacts of sea-level rise, the effects of climate change on marine ecosystems, greater understanding of marine food webs, and better approaches for forecasting hazards such as mega-earthquakes and tsunamis. The report also recommends that the National Science Foundation rebalance its funding for ocean science research, which in recent years has shifted toward research infrastructure at the expense of core science programs.

  • Bulletin of the Atomic Scientists moves Doomsday Clock forward in dire warning

    TheBulletin of the Atomic Scientists, a 70-year old publication which monitors nuclear, security, and environmental developments, has pushed ahead its symbolic Doomsday Clock by two minutes — from five minutes to midnight to three minutes — amidst growing concerns about climate change and nuclear arsenal upkeep.

  • New climate change projections for Australia

    CSIRO and the Australian government’s Bureau of Meteorology the other day released climate change projections for Australia which provide updated national and regional information on how the climate may change to the end of the twenty-first century. The projections are the most comprehensive ever released for Australia and have been prepared with an emphasis on informing impact assessment and planning in the natural resource management sector. Information has been drawn from simulations based on up to forty global climate models.

  • Miami Beach to raise West Avenue in the face of sea-level rise

    City planners in Miami Beach will begin the first phase of a two-part project to raise West Avenue between 1.5 to two feet during the next few years in an effort to prepare the area in the face of sea-level rise. The project will coincide with stormwater drainage and sewer improvements which include installing more pumps to prevent flooding from rain and high tides.

  • Ohio helps resident pay for tornado safe rooms

    In recent years, Ohio has averaged twenty-three tornadoes annually. The state also experienced winds topping 70 mph during Hurricane Ike in 2008, 100 mph in the derecho during the summer of 2012, and near hurricane-force winds along Lake Erie in northeastern Ohio during superstorm Sandy in the fall of 2012. Many Ohio residents living along “Tornado Alley” have rehearsed their escape plans several times to prepare for the next time a tornado touches ground. To offer residents better protection, since 2013 the Ohio Emergency Management Agency(EMA) has been helping qualified homeowners pay for safe rooms which can withstand the most destructive windstorms.

  • Drawing disaster response lessons by comparing quake responses

    Following the devastating 2011 Great East Japan Earthquake which hit the Tohoku region of Japan, many local and provincial governments rushed to aid the people in the area with personnel and materials, providing important relief in a time of crisis. At a recent symposium, some were comparing the response to the 2011 disaster to the response to the Great Hanshin-Awaji Earthquake of 1995 in order to draw lessons and offer guidelines in effective crisis management.

  • Fracking-induced tremors lead to changes in building codes, insurance rates

    For its upcoming National Seismic Hazard Map, used by engineers to update building and construction codes and by insurers to set policy rates, the U.S. Geological Survey(USGS) will take into account risks posed by induced or man-made earthquakes. For North Texas, where earthquakes are historically uncommon, an increase in earthquake risk is likely as the Dallas area has suffered more than 120 earthquakes since 2008. Scientists have attributed these earthquakes to nearby fracking operations.

  • Atmospheric rivers, cloud-creating aerosol particles, and California water situation

    In the midst of the California rainy season, scientists – using aircraft, research vessel, and ground stations — are embarking on a field campaign designed to improve the understanding of the natural and human-caused phenomena that determine when and how the state gets its precipitation. They will do so by studying atmospheric rivers, meteorological events that include the famous rainmaker known as the Pineapple Express. Atmospheric rivers, which produce up to 50 percent of California’s precipitation and can transport 10-20 times the flow of the Mississippi River.
