• Warming pushes Western U.S. toward driest period in 1,000 years

    Study warns of unprecedented risk of drought in twenty-first century. Today, eleven of the past fourteen years have been drought years in much of the American West, including California, Nevada, New Mexico, and Arizona and across the Southern Plains to Texas and Oklahoma. The current drought directly affects more than sixty-four million people in the Southwest and Southern Plains, and many more are indirectly affected because of the impacts on agricultural regions. A new study predicts that during the second half of the twenty-first century, the U.S. Southwest and Great Plains will face persistent drought worse than anything seen in times ancient or modern, with the drying conditions “driven primarily” by human-induced global warming.

  • Geoengineering solutions to climate change not likely to be ready in time

    Governments have been slow to adopt measures to deal with climate change, so it is not surprising that scientists and engineers have been offering different technologies which would help slow down, or even reverse, global warming. These different technologies are called “geoengineering.” Some scientists have now concluded that even if a technological solution is found, it may not be developed and implemented quickly enough to affect the change required.

  • Midwest floods becoming more frequent

    The U.S. Midwest region and surrounding states have endured increasingly more frequent floods during the last half-century, according to results of a new study. The findings fit well with current thinking among scientists about how the hydrologic cycle is being affected by climate change. In general, as the atmosphere becomes warmer, it can hold more moisture. One consequence of higher water vapor concentrations is more frequent, intense precipitation.  The floods caused agricultural and other economic losses in the billions of dollars, displaced people, and led to loss of life.

  • Oklahoma rejects “rush to judgment” on the connection between fracking and earthquakes

    Between 1978 to mid-2009, Oklahoma recorded one or two 3.0 or greater magnitude earthquakes. Last year the state experienced 585 earthquakes of 3.0 magnitude or greater. Studies conducted by seismologists, including those who work with the United States Geological Survey(USGS), have attributed the spike in earthquakes to the roughly 3,200 active disposal wells, in which wastewater produced during oil and gas drilling is stored deep underground, and independent scientific studies have established the causal relationship between fracking and earthquake. Arkansas, Ohio, and Colorado have imposed temporary restrictions on fracking, while Texas and Illinois are considering similar measures – but the Oklahoma Geological Survey says that “We consider a rush to judgment about earthquakes being triggered to be harmful to state, public and industry interests.”

  • Texas appoints seismologist to examine wave of Irving-area quakes

    Research over decades has shown the fracking process — injecting fluid underground to release oil — has been the cause of fault slips and fractures. The fluid can often lubricate existing faults and cause them to slip. The Texas Railroad Commission (RRC) has turned to David Craig Pearson to help study a series of quakes which hit the area of Irving within a span of a few days. A UT-Austin seismologist has already published a report which found that most earthquakes in Texas’s oil-rich Barnett Shale occurred within two miles of an injection well, essentially proving that some of the quakes are caused by fracking. Pearson’s appointment was not universally welcomed, as some see him as too close to industry. “I’m absolutely engaged with trying to figure out the cause of all earthquakes throughout Texas,” said Pearson. “I’m a scientists first, and a Railroad Commission employee second.”

  • Obama continues push for cybersecurity bill

    Following his remarks on cybersecurity at the 2015 State of the Union address, President Barack Obama will attenda summit on Cybersecurity and Consumer Protectionat Stanford Universitythis Friday. Attendees will include major stakeholders in cybersecurity and consumer financial protection issues, including executives from the financial services, telecommunications, and retail industries, as well as law enforcement officials and consumer advocates. Obama has requested $14 billion for cybersecurity initiatives in the 2016 federal budget, a 10 percent increase from 2015 budget.

  • "uisance flooding” becoming problem for many U.S. coastal communities

    Scientists say that floods and surges will become a regular feature of life in many coastal U.S. cities, even when the weather is not particularly bad or stormy. Some communities along the East Coast are flooding even in calm, clear weather, indicating a trend of “nuisance floods” which will increasingly plague many parts of the U.S. coast in the future. Annapolis, Maryland, is but one example: From 1957 to 1963, flooding hit the city about 3.8 days a year. From 2007 to 2013, that average had increased to 39.3 days a year.

  • Coastal communities can lower flood insurance rates by addressing sea-level rise

    City leaders and property developers in Tampa Bay are urging coastal communities to prepare today for sea-level rise and future floods in order to keep flood insurance rates low in the future. FEMA, which administers the National Flood Insurance Program(NFIP), is increasing flood insurance premiums across the country, partly to offset losses from recent disasters such as hurricanes Katrina and Sandy. Cities can reduce insurance premiums for nearly all residents who carry flood coverage by improving storm-water drainage, updating building codes to reflect projected rise in sea-levels, moving homes out of potentially hazardous areas, and effectively informing residents about storm danger and evacuation routes.

  • Rising seas may force coastal communities to “strategically retreat”: Corps of Engineers

    In response to Hurricane Sandy, the U.S. Army Corps of Engineershas conducted a two-year study on 31,200 miles of coastal, back bay, and estuarine areas in ten states. The Corps has identified nine high-risk areas for future flooding along the North Atlantic coast. The study offers a nine-step planning process on how to identify risky areas and develop strategies to reduce the risk. It also recommends several ways communities can deal with rising sea levels, including bulkheads, seawalls, levees, elevation of homes and roads, dunes, breakwaters, living shorelines made of natural materials, groins, deployable floodwalls, and reefs. “Some communities looking out twenty years or more may consider strategic retreat and relocating people to higher ground. Each community has to evaluate which measures will work for them,” said Amy Guise, the chief of the Army Corps command center in Baltimore.

  • U.S. yet to develop a strategy to secure nation’s critical infrastructure

    For years, the U.S. government has warned federal and state agencies about the threat posed by hackers who may target computer systems responsible for operating nuclear plants, electric substations, oil and gas pipelines, transit systems, chemical facilities, and drinking water facilities. In February 2013, President Barack Obama issued a directive stating, “It is the policy of the United States to strengthen the security and resilience of its critical infrastructure against both physical and cyber threats.” Two years later the federal government has yet to develop or adopt a consensus on how to secure America’s critical infrastructure from cyber criminals.

  • 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.

  • Idaho bolsters the state’s cyber defenses

    Idaho’s director of the Bureau of Homeland Security says that cyber threats remain the most important yet least understood risk to government and the private sector. He has announced plans to tackle that vulnerability in the state. The director of the Bureau says that cybersecurity will never be perfect, which makes it imperative for organizations like the Idaho Bureau of Homeland Security to focus on planning that incorporates not just defense, but also detection and the mitigation of damage that has already occurred.

  • Early warning systems to boost security for critical infrastructures

    Using data mining, data fusion, and what are known as “rule based engines,” the EU-funded ARGOS, which stands for Advanced Protection of Critical Buildings by Overhauling Anticipating Systems, has developed an innovative early warning security system for critical infrastructure facilities, letting site operators know whether there is a potential threat. The rule-based engines allow operators to “teach” the system what alarms are true enabling systems to ‘learn’ and improve over time. The early warning systems extend the sites’ “security zone” and helps vital infrastructure to become more secure against intruders.

  • 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.
